主要技术参数Main technical parameters

基本组件Basic component

◆SFL型负荷开关(ABB 原装件)

SFL型负荷开关为双断点、旋转式动触头，以SF6气体为灭弧介质，动静触头置于加强结构的模铸环氧树脂外壳中。在操作轴引出端是一个透明的热压成型的塑料端盖，透过端盖可以观察状态。

每个开关充以1.4帕气压的SF6气体后是永久密封的(SFL意“永远密封”),用氦检测器可以检查有无气体渗漏。

开关垂直或水平安装不限，在单元式柜内，典型的安装方式是在电缆室和母线室之间置一钢隔板，水平安装。这种安装方式将开关外壳封在接地的钢板内并将母线与电缆接头之间相隔离，以符合运行维护的最严格安全要求。

假若内部发生燃弧，在外壳后部有一个结构薄弱点，它将被冲开，把电弧气体导出开关之外，随后柜上面的泄弧活门被冲开并将过压气体导向柜外。

SFL type load switch (ABB original)

The SFL type load switch is a double-break, rotary moving contact with SF6 gas as the arc extinguishing medium, and the dynamic and static contact is placed in the moldcast epoxy resin shell with reinforced structure. At the leading end of the operating shaft is a transparent hot-pressed plastic end cover, through which the state can be observed.

Each switch is permanently sealed with 1.4pa of SF6 gas (SFL stands for "sealed forever") and can be checked for gas leakage with a helium detector.

The switch is not limited to vertical or horizontal installation. In the unit cabinet, the typical installation method is to place a steel partition between the cable room and the bus room, and install it horizontally. This installation encloses the switch housing in a grounded steel plate and isolates the busbar from the cable connector to meet the most stringent safety requirements for operation and maintenance.

If an internal arc occurs, there is a structural weakness at the back of the housing, which will be blown open, exporting the arc gas out of the switch, and then the arc relief valve above the cabinet will be blown open and direct the overpressured gas out of the cabinet.

◆VD4-S 真空断路器(ABB 原装件)

VD4-S型真空断路器是专为单元开关柜设计的，其开断容量足以应付各种状态，包括正常投切设备或分支网络的操作以及特殊情况下开断短路等。

真空断路器对在工作电流范围内频繁操作的网络尤为适用。VD4-S真空断路器配有弹簧操作机构具有重合闸功能(分-0.3s- 合分-180s-合分),并且动作可靠，寿命长。整个断路器包括三只真空开关，外部是树脂绝缘筒，立式结构。

电弧的熄灭是由于灭弧触头的螺旋型沟槽使电弧产生强制性移位的结果。由于开关绝缘筒内最低静态真空度是10-4至10-8帕，所以尽管开关触头间相对只有不大的间隙，却可以得到很高的绝缘强度。电弧在短路电流第一个零点时熄灭。由于触头间隙小，电弧压降处金属气体等离子区导电率高，加上燃弧时间短，使得电弧能

量极低，这对触头乃至整个开关寿命的延长都是有利的。

◆VD4-S vacuum Circuit breaker (ABB original)

VD4-S vacuum circuit breakeris specially designed for unit switchgear, its breaking capacity is sufficient to cope with a variety of conditions, including normal switching equipment or branch network operation and special circumstances to break short circuit.

Vacuum circuit breakers are particularly suitable for networks that operate frequently within the operating current range. VD4-S vacuum circuit breaker is equipped with a spring operating mechanism with reclosing function (min. 0.3s-closing - 180S-closing), and reliable operation, long life. The whole circuit breaker includes three vacuum switches, and the outside is a resin-insulated cylinder with a vertical structure.

The quenching of the arc is caused by the forced displacement of arc caused by the spiral groove of the arc extinguishing contact. Because the minimum static vacuum degree in the switch insulation cylinder is 10-4 to 10-8 pa, a high insulation strength can be obtained despite the relatively small gap between the switch contacts. The arc is extinguished at the first zero of the shortcircuit current. Due to the small contact gap, the high conductivity of metal gas plasma region at arc pressure drop, and the short arc burning time, the arc energy is generated

The amount is extremely low, which is beneficial for the extension of the life of the contacts and even the entire switch.

◆SFL型SF6 断路器(ABB 原装件)

SFL型SF6断路器是专为环网开关柜设计的，其开断容量足以应付各种状态，包括正常投切设备或分支网络的操作以及在特殊情况下开断短路等。新一代HAD具有最新的SF6开断工艺，加之结构简单，只需很小的操作能量，如此简单的储能式操作机构具有使用时机械寿命长的特点。断路器选用弹簧操作机构可以实现自动重合闸操作。

开关开断部分的特殊结构能够使电气寿命延长得到异乎寻常的保证。开关是做成分体独立柱式结构，立式安放。开关采用自能吹弧式原理，即用电弧自身能量来灭弧。当断路器分闸时，在灭弧室内的动静触头问产生电弧，电弧产生的高温和电离高效应使SF6气体压力在灭弧室内迅猛升高，随着压力的增强和燃弧触头的渐次分开将气体经由喷嘴强行喷向灭弧室外，于是使电弧变稀疏、冷却、遮断，并阻止重燃，因此开关运动部分只需要很少的能量，更加增进了长期运行的可靠性。

SFL type SF6 Circuit breaker (ABB original)

The SFL type SF6 circuit breaker is specially designed for ring switchgear, and its breaking capacity is sufficient to cope with various conditions, including normal switching equipment or branch network operationand breaking short circuit in special circumstances. The new generation of HAD has the latest SF6 breaking process, coupled with a simple structure, only a small operating energy, such a simple energy storage operating mechanism has a long mechanical life. Automatic reclosing operation can be realized by using spring operating mechanism.

The special structure of the breaking part of the switch enables the extension of the electrical life to be unusually guaranteed. The switch is made of a separate column structure, vertical placement. The switch adopts the principle of self-energy blowing arc, that is, the arc is extinguished by the arc's own energy. When the circuit breaker is opened, the dynamic and static contacts in the arc extinguishing room will produce an arc. The high temperature and high ionization efficiency generated by the arc will cause the SF6 gas pressure to rise rapidly in the arc extinguishing room. With the increase of pressure and the gradual separation of the arc burning contacts, the gas will be forcibly sprayed to the outside of the arc extinguishing room through the nozzle, so that the arc will be sparse, cooled, blocked and prevented from re-burning. Therefore, the moving part of the switch requires very little energy, which further improves the reliability of long-term operation.

主要结构特征Main structural features

◆开关设备可以背靠背组成双重排列，提高了开关设备的安全性和灵活性，减少占地面积。

◆The switchgear can be composed of back-to-back dual arrangement, which improves the safety and flexibility of the switchgear and reduces the footprint

◆外壳

开关设备的外壳选用进口敷铝锌钢板，经CNC机床加工，采用多重折边工艺制作而成。整个柜体具有精度高和很强的抗腐蚀与抗氧化性能，而且由于采用多重折边工艺，使柜体比其他同类设备柜体整体重量轻、机械强度高，外形美观。柜体采用组装式结构，用拉铆螺母和高强度的螺栓连接而成。使加工生产周期缩短，零部件通用性强，占地面积少，便于组织生产。

◆Shell

The shell of the switchgear is made of imported aluminum zinc steel plate, which is processed by CNCmachine tool and made by multiple hemming process. The whole cabinet has high precision and strong corrosion resistance and oxidation resistance, and because of the use of multiple flanging process, the cabinet is lighter than other similar equipment cabinets, high mechanical strength and beautiful appearance. The cabinet is of assembled construction, connected by riveted nuts and high strength bolts. The processing and production cycle is shortened, the parts are versatile,the floor area is small, and the production is easy to organize.

手车

手车骨架采用薄钢板经CNC机床加工后组装而成。手车与柜体配合精度高，机械联锁安全、可靠、灵活。手车根据用途不同分为断路器手车、电压互感器手车、计量手车、隔离手车等，同规格的手车可以自由互换。手车在柜体内有断开/试验位置和工作位置，每一位置都分别有定位装置，以保证联锁可靠。各种手车均采用丝杆推进、推出，操作轻便、灵活，适合值班人员操作。当手车需要移开柜体时，用一台专用转运车，就可方便取出，以便进行各种检查和维护。

当手车用运转车运入柜体断路器室时，便能可靠锁定在断开/试验位置，并且柜体位置指示灯显示其所在位置。只有手车完全锁定后，才能摇动丝杆推动结构，将手车推向工作位置。手车到达工作位置时，推进手柄操作力突然加大并摇转不动，其对应位置指示灯便显示其所在位置。手车的机械联锁能可靠保证手车只有在工作位置或试验位置，断路器才能进行合闸;而且断路器只有在分闸状态，手车才能移动。

Handcart

The frame of the handcart is made of thin steel plate processed by CNC machine tool and assembled. The hand car and the cabinet have high precision, and the mechanical interlock is safe, reliable and flexible. According to different uses, the handcart is divided into circuit breakerhandcart, voltage transformer handcart, measuringhandcart, isolation handcart, etc., andthe handcart of the same specification can be freely exchanged. The hand carhas a disconnect/test position and a working position in the cabinet body, and each position has a positioning device to ensure reliable interlocking. All kinds of handcarts are promoted and launched by screw rod, and the operation is light and flexible, suitable for duty personnel. When the hand car needs to remove the cabinet, a special transfer car can be used to remove it for various inspections and maintenance.

When the mobile car is transported into the cabinet breaker room, it can be reliably locked in the disconnect/test position, and the cabinet position indicator shows its position. Only after the hand car is completely locked can the screw be shaken to push the structure and push the hand car to the working position. When the hand car reaches the working position, the operation force of the push handle suddenly increases and doesnot move, and its corresponding position indicator will show its position. The mechanical interlock of the hand car can reliably ensure that the circuit breaker can be closed only in the working position or the test position; And the circuit breaker can only move when the brake is on.

隔室

开关设备主要电气元件都有其独立的隔室，既：断路器手车室、母线室、电缆室、继电器仪表室。各隔室间防护等级都达到IP2X。除继电器仪表室外，其他三个隔室都分别有泄压通道。由于采用了中置式形式，电缆室空间大为增加，因此设备可并接多路电缆。

A、母线隔室A;主母线是单台拼接相互贯穿连接，通过分支母线(静触头盒)及主母线绝缘套管固定。主母线 和联络母线为矩形截面的铜排，用于大电流负荷时采用双母排。对于特殊需要。母线可用热缩套管和定制的绝缘罩盒覆盖。相邻柜母线间安装有绝缘套管，如果出现内部故障电弧时，套管能有效把事故限制在隔室内而不向其它间隔蔓延。

B、断路器隔室B:隔室两侧安装了轨道，供手车在柜内由断开/试验位置移动至工作位置。静触头盒的隔板(活门)安装在手车室的后壁处，当手车从断开/试验位置移动到工作位置过程中，静触头盒口上的上、下活门与手车联动自动打开;当反向移动时，活门则自动闭合，直至手车退至一定位置而完全覆盖住静触头盒，形成有效的隔离。由于上、下活门之间不联动，在检修时，可锁定带电侧的活门，从而保证检修维护人员不触及带电体。在断路器室门关闭时，手车同样能被操作。通过门上的观察窗，可以观察隔室内手车所处位置，合、分闸指示及储能状况。

C、电缆隔室：开关设备采用中置式，因而电缆室空间较大。电流互感器、接地开关装在隔室后壁上(接地开关也可根据客户需要装在开关柜的中部)，避雷器安装于隔室后下部。将手车和可抽出式水平隔板移开后，施工人员能从正面进入柜内安装和维护。电缆室内的电缆连接导体，每相可接1\~3根电缆，必要时每相可并接6根电缆，电缆隔室的柜底配制可卸式开缝的金属封板或不导磁金属板，确保施工方便。

D、继电器仪表室：继电器仪表室内可安装继电保护元件、仪表、带电显示指示器以及特殊要求的二次设备。控制线路敷设在线槽内，线槽有金属板，可使二次线与高压元件隔离。左前侧线槽是为控制电缆的引进和引出预留的，底板相应部位开有二次电缆穿线孔。在继电器仪表室的顶板上还留有便于施工的母线穿越孔。接线时仪表室顶盖板可以翻开，便于小母线的安装。

◆Compartments

The main electrical components of the switchgear have their own independent compartments, namely: circuit breaker handcart room, bus bar room, cable room, relay instrument room. The protection level of each compartment reaches IP2X. In addition to the relay meter outside, the other three compartments have separate pressure relief channels. Due to the use of the central form, the cable room space is greatly increased, so the equipment can be connected to multiple cables.

A、Bus compartment A; The main busbar is a single splicingthrough each other and is fixed through the branch busbar (static contact box) and the main busbar insulation sleeve. The main busbar and the liaison busbar are copper bars of rectangular section, and double busbar is used for high current load. For special needs. The bus bar can be covered with heat shrink bushing and custom edge cover box. An insulating sleeve is installed between the bus bars of the adjacent cabinets. If there is an internal fault arc, the sleeve can effectively limit the accident to the compartment and not spread to other compartments.

B、Circuit breaker compartment B: Tracks are installed on both sides of the compartment for the hand car to move from the disconnect/test position to the working position in the cabinet. The partition board (trap door) of the quiet contact box isinstalled on the back wall of the handcar room. When the handcar moves from the disconnecting/testing position to the working position, the upper and lower valves on the mouth of the quiet contact box are linked with the handcar to open automatically; When moving in the opposite direction, the valve closes automatically until the hand car has retreated to a position that completely covers the static contact box, creating an effective isolation. Because the upper and lower valves are not connected, the valve on the live side can be locked during maintenance to ensure that maintenance personnel do not touch the live part. The hand car can also be operated while the circuit breaker door is closed. Through the observation window on the door, you can observe the position of the handcart in the compartment, the closing and opening of the brake indication and the energy storage status.

C、Cable compartment: The switchgear adopts the middle type, so the cable room space is larger. The current transformer and ground switch are installed on the back wall of the compartment (the ground switch can alsobe installed in the middle of the switch cabinet according to customer needs), and the arrester is installed in the lower part of the back of the compartment. After the handcart and withdrawable horizontal partition are removed, the construction personnel can enter the cabinet from the front to install and maintain. The cable connecting conductor in the cable room can be connected with 1 to 3 cables for each phase, and 6 cables for each phase if necessary. The bottom of the cable compartment is eguippedwith detachable slit metal sealing plates or non-magnetic conductive metal plates to ensure convenient construction.

D、 Relay instrument room: Relay instrument room can be installed relay protection components, meters, live display indicators and special requirements of secondary equipment. The control line is laid in the online groove, and the wire groove has a metal plate, which can isolate the secondary line from the high voltage element. The left front side cable slot is reserved for importing and routing control cables. A secondary cable threading hole is provided on the corresponding part of the baseplate. The top plate of the relay instrument room is also provided with a bus crossing hole for easy construction. The top cover plate of the instrument room can be opened to facilitate the installation of small bus bars.

◆泄压装置

在手车室、母线室和电缆室的上方均设有泄压装置，当隔室内发生故障产生电弧时，开关柜内部气压升高，装设在前门上的特殊密封圈把柜门封闭起来，顶部装备的泄压金属板被自动打开，释放压力和高温气体，确保操作人员和开关设备的安全。

◆Pressure relief device

The pressure relief device is providedabove the handcart room, bus bar room and cable room. When the fault occurs in the compartment and the arc occurs, the pressure inside the switch cabinet increases, the special sealing ring installed on the front door closes the cabinet door, and the pressure relief metal plate equipped on the top is automatically opened to release pressure and high temperature gas, ensuring the safety of the operator and the switchgear.

◆二次插头与手车的位置联系

无接地开关的断路器柜操作

A、将断路器可移开部件装入柜体：把断路器手车装在转运车上并锁定好，将转运车推到柜前，把小车升到合适位置后，将转运车前部定位锁板插入柜体中隔板插口并将转运车与柜体锁定，打开断路器小车锁定钩，将断 路器手车平稳推入柜体同时锁定，当确认已将手车与柜体锁定之后，解除转运车与柜体的锁定，将转运车拉开。

B、手车在柜内操作：断路器手车装入柜体后即处于断开位置，将辅助回路二次插头插好后手车处于试验位置。若通电则仪表室面板上试验位置指示灯亮，此时主回路接通，断路器处于工作位置，可通过控制回路对其进行合、分操作。

◆Circuit breaker cabinet operation without ground switch

A、 The circuit breaker removable parts into the cabinet: Install the circuit breaker handcart on the transfer car and lock it, push the transfer car to the front of the cabinet, lift the car to the appropriate position, insert the positioning lock plate of the front part of the transfer car into the bulkhead jack of the cabinet body and lock the transfer car with the cabinet body, open the locking hook of the circuit breaker car, and push the breaker handcart smoothly into the cabinet body and lock it at the same time. After confirming that the handcart and the cabinet body have been locked, Remove the lock between the transfer car and the cabinet. and pull the transfer car away.

B、 The hand car in the cabinet operation: the circuit breaker hand car into the cabinet is in the disconnected position, the secondary plug of the auxiliary circuit is inserted after the hand car is in the test position. If the power is on, the test position indicator on the panel of the instrument room is on, and the main circuit is connected and the circuit breaker is in the working position, and it can be operated by the control circuit.

若准备将小车从工作位置退出，首先应确认断路器已处于分闸关态，插入手车操作摇把，逆时针转动直到摇把明显受阻并听到清脆的辅助开关切换，小车便回到试验位置。此时，主回路已经完全断开，金属活门关闭。

A、从柜中取出手车:从柜内取出手车时要确定断路器处于分闸状态，然后解除辅助回路二次插头和锁在手车架上，此时将转运推至柜前(与手车装入柜内时相同)并锁定，然后将手车解锁并向外拉出。当手车完全进到转 运车上并确认与转运车锁定后，解除运转车与柜体的锁定，把转运车向后拉出。如手车要用转运车运输较长距离时，在推动转运小车过程中要格外小心，以避免运输过程中发生倾翻等事故。

B、断路器手车在柜内的分、合闸状态确认：分、合闸状态可由断路器手车面板上的分、合指示牌及仪表室面板上分、合闸指示灯来判定。若透过柜体中面板观察看到手车面板上绿色的分闸指示牌则判定断路器处于分开状态，此时如果辅助回路二次插头接通操作电源，则仪表面板上分闸指示灯亮。

If you are ready to withdraw the car from the working position, first confirm that the circuit breaker is in the switch off state, insert the hand car operation crank, turn counterclockwise until the crank is clearly blocked and hear the crisp auxiliary switch switch, the car will return to the test position. At this point, the main circuit has been completely disconnected and the metal valve is closed.

A、 Take out the car from the cabinet: when taking out the car from the cabinet, make sure that the circuit breaker is in the opening state, and then remove the secondary plug of the auxiliary circuit and lock the car frame, at this time, push the transfer to the front of the cabinet (the same as when the car is loaded into the cabinet) and lock, and then unlock the car and pull out. When the hand car is fully into the transfer car and confirmed to lock the transfer car, remove the lock between the running car and the cabinet, and pull the transfer car out backwards. If the hand car is to be transported by the transfer car for a long distance, extra care should be taken in the process of pushing the transfer car to avoid accidents such as tipping during transportation.

B、 Circuit breaker hand car in the cabinet of the division, closing state confirmation: the division, closing state can be determined by the circuit breaker hand car panel on the division, closing indicator and instrument room panel on the division, closing indicator light. If the green switch indicator on the handcar panel is seen through the cabinet panel, it is determined that the circuit breaker is in a separate state. At this time, if the secondary plug of the auxiliary circuit is connected to the operating power, the switch indicator on the instrument panel will light up.

有接地开关的断路器柜操作

将断路器手车推入柜内取出手车程序，与无接地开关的断路器柜的操作程序完全相同。仅将手车在柜内操作和

接地开关操作过程中要注意的地方叙述如下：

A、在柜外操作时：当准备将手车推入工作位置时，除了要遵守5.1b)中提请注意的诸项要求外，还应确认接地开关要处于分闸状态，否则下一步操作无法完成。

B、分、合接地开关操作:若要合接地开关，首先应确定手车已退到试验/断开位置，并取下推进摇把，然后按下接地开关操作孔的联锁弯板，插入接地开关操作手柄，顺时针转动90°,接地开关处于合闸状态。若再逆时针转动90°,便将接地开关分闸。

◆Circuit breaker cabinet operation with ground switch

The procedure of pushing the circuit breaker into the cabinet and taking out the circuit breaker is exactly the same as the operation procedure of the circuit breaker cabinet without ground switch. Only the hand car will be operated in the cabinet and The places to pay attention to during the operation of the grounding switch are described as follows:

A、When operating outside the cabinet: When preparing to push the handcart into the working position, in addition to complying with the reguirements drawn to attention in 5.1b), it should also confirm the connectionthe ground switch must be in the off state, otherwise the next operation cannot be completed.

B、 Switch and close ground switch operation: If you want to close the ground switch, first make sure that the hand car has retreated to the test/disconnect position, and remove the push crank, then press the interlock bend plate of the ground switch operating hole, insert the ground switch operating handle, turn 90° clockwise, and the ground switch is in the closing state. If you turn 90° counterclockwise again, the ground switch will be opened.

一般隔离柜操作

隔离插头不具备接通和断开负荷电流的能力，因此在带负荷的情况下不允许移动手车。在进行隔离操作手车作时，必须保证先将与之相配合的断路器分闸(见5.1中d),断路器分闸后其辅助触点转换解除与之融合的隔离手车上的电气联锁，只有这时才能操作隔离手车。具体操作程序与断路器手车操作程序相同。

KYN28A-12型开关设备是以机械联锁实现其“防误”功能。联锁操作过程中如发现操作阻力增大，应在排除有误操作可能的前提下，及时检查联锁装置。

◆General isolation cabinet operation

The isolation plug does not have the ability to turn on and off the load current, so it is not allowed to move the handcart under load. When the isolation operation is carried out, it must be ensured that the circuit breaker matched with it is switched off first (see d in 5.1). After the circuit breaker is switched on, its auxiliary contact switches to release the electrical interlock of the integrated isolation car. Only then can the isolation car be operated. The specific operation procedure is the same as that of the circuit breaker hand car.

KYN28A-12switchgear uses mechanical interlocking to achieve its "error-proof" function. If it is found that the operating resistance increases during the interlocking operation, the interlocking device should be checked in time on the premise of excluding the possibility of incorrect operation.
