Switch cabinet for double-sided maintenance, the front overhaul of the relay room secondary components, maintenance of operating mechanism, mechanical interlocking and transmission parts, overhaul of circuit breakers. After the maintenance of the main bus and cable terminals, there are lights in the circuit breaker room and the cable room. Under the front door is a ground copper bus that is parallel to the width of the cabinet. Its section is 4 x 40mm².
Mechanical interlocking: In order to prevent the isolation switch with load switching,to prevent the mis-switching of the circuit breaker, to prevent straying into the live interval; Anti-livegrounding switch; To prevent the groundingknife from closing, the switchgear adopts the corresponding mechanical interlock. The operation principle of the mechanical interlock is as follows:
停电操作(运行一检修)
开关柜处于工作位置，即上下隔离开关、断路器处于合闸状态，前后门已锁好，并处于带电运行之中，这时的小手柄处于工作位置。先将断路器分闸后，再将小手柄扳到“分断闭锁”位置，这时断路器不能合闸，将操作手柄插入下隔离的操作孔内从上往下拉，拉到下隔离分闸位置，再将手柄拿下，再插入上隔离操作孔内，从上往下拉，拉到上隔离分闸位置。再将操作手柄拿下，插入接地开关操作孔内，从下向上推，使接地开关处于合闸位置，这时可将小于手柄扳到“检修”位置。可先打开前门，取出门后边钥匙打开后门，停电操作完甲，检修人员对断路器室及电缆室进行维护和检修。
◆Power outage operation (operation and maintenance)
The switch cabinet is in the working position, that is, the upper and lower isolation switch, the circuit breaker is in the closing state, the front and back doors are locked, and are in live operation, and the small handle is in the working position. First turn off the circuit breaker, and then turn the small handle to the "break lock" position, then the circuit breaker can not close, insert the operating handle into the lower isolation operating hole from the top down to the lower isolation opening position, and then remove the handle, and then insert the upper isolation operating hole, pull down from the top to the upper isolation opening position. Then take off the handle, insert it into the ground switch operating hole, and push it up from the bottom to make the ground switch in the closing position. In this case, you can switch the handle to the "maintenance" position. You can open the front door first, take out the key behind the door to open the back door, after the power failure operation, maintenance personnel to the circuit breaker room and cable room maintenance and overhaul.
送电操作(检修一运行)
若已检修完毕，需要送电，其操作程序如下:将后门关闭，钥匙取出后关前门，将小手柄从“检修”位置扳到“分断闭锁”位置，这时前门被锁定，断路器不能合闸，用操作手柄插入接地开关操作孔内，从上向下拉，使接地开关处于分闸位置，将操作手柄拿下，再插入上隔离的操作孔内，从下向上推，使上隔离处于合闸位置，将操作手柄拿下，插入下隔离的操作孔内，从下向上推使下隔离处于合闸位置，取出操作手柄，将小手柄扳至工作位置，这时可将断路器合闸。
◆Power supply operation (maintenance and operation)
If the maintenance is completed and power needs to be sent, the operation procedure is as follows: Close the back door, take out the key and close the front door. Switch the small handle from the "overhaul" position to the "break lock" position. At this time, the front door islocked and the circuit breaker cannot be closed. Insert the operating handle into the operating hole of the grounding switch and pull it down from the top to make the grounding switch in the opening position. Make the upper isolation in the closing position, remove the operating handle, insert it into the operating hole of the lower isolation, push it up from the bottom to make the lower isolation in the closing position, remove the operating handle, turn the small handle to the working position, then thecircuit breaker can be closed.

柜体分区设计Cabinet partition design
◆IMCC柜根据需要可组成单面操作柜或双面操作柜，每一柜体又固定分隔成三个小室。即主母线室、电器室和电缆室。(具体见图2)
◆IMCC cabinets can be composed of single-sided or double-sided operating cabinets according to needs, and each cabinet is fixed and divided into three small rooms. The main bus room, electrical room and cable room. (See Figure 2 for details)
安全保护系统
每柜都有一块阻燃型的高密度聚氨脂塑料功能板，或经过电镀的隔板安装在主母线室与电器室之间，其作用为有效防止开关元件因故障引起的飞弧与母线之间短路造成的事故，使操作更安全。
上下层抽屉之间都有带有通风孔的镀锌金属底板相隔离，对相邻回路之间具有较强的隔离作用。
柜内采用了多种塑料组件以支撑带电部份，这些组件要求是无卤素的，并具有CTI300等级的防漏电性能。
柜内设有独立的PE接地系统和N中性导体，都贯穿整个装置，各回路接地或接零都可就近联接。整个母线系统安装见图3所示。框架结构件采用自攻螺钉联接，具有较高的接地可靠性。(具体见图3)
◆Security protection system
Each cabinet has a flame-retardant high-density polyurethane plastic function board, or an electroplated partition installed between the main bus room and the electrical room, its role is to effectively prevent the switch components due to failure caused by flying arc and short circuit between the bus accidents, so that the operation is safer.
The upper and lower drawers are separated by a galvanized metal base plate with ventilation holes, which has a strong isolation effect between adjacent circuits.
A variety of plastic components are used in the cabinet to support the live parts. These components are required to be halogenfree and have CTI300 grade leakage resistance.
The cabinet is equipped withan independent PE grounding system and N neutral conductor, which run through the entire device, and the grounding or zero connection of each loop can be connected nearby. The entire bus system installation is shown in Figure 3. The frame structure is connected with self-tapping screws, which has high ground reliability. (See Figure 3 for details)
母线系统
开关柜的水平母线布置在开关柜的水平母线隔离室内，可置于柜后或柜顶，后出线结构的柜体中水平母线置于柜顶。配电母线(垂直母线)组装在阻燃型塑料功能板中，既可防止电弧引起的放电，又能防止人体接触，通过联接件与主母线联接。
◆Bus system
The horizontal bus bar of the switch cabinet is arranged in the horizontal bus bar isolation room of the switch cabinet, which can be placed behind the cabinet or on the top of the cabinet. The horizontal bus bar of the rear outlet structure is placed on the top of the cabinet. The distribution busbar (vertical busbar) is assembled in the flame-retardant plastic function board, which can prevent the discharge caused by the arc and prevent human contact, and is connected with the main busbar through the coupling.
抽屉的电气和机械联锁
抽屉单元有可靠的机械联锁装置，通过操作手柄控制，具有明显的分闸、合闸、试验、抽出和隔离位置。
为加强安全防范，操作手柄定位后可加上挂锁，最多可加三把锁。
◆Electrical and mechanical interlocking of drawers
The drawer unit has a reliable mechanical interlocking device, which is controlled by an operatinghandle and has distinct opening,closing, testing, extraction and isolation positions.
In order to enhance safetyprecautions, the padlock can be added after the operation handleis positioned, and up to three locks can be added.
后出线开关柜结构
柜后出线可以减少开关柜排列宽度。后出线开关柜的主母线水平安装在开关柜的顶部，柜的后半部为电缆室，进出线电缆均在柜后电缆室连接。开关柜的正面为装置小室，安装开关设备的功能单元。该系统设计将开关柜侧面的电缆室移至后半柜，大大减少了开关柜的排列宽度，以进一步满足变电站空间布置的要求。
馈电柜柜宽600mm，深1000mm，顶部为独立的母线室，与装置小室隔离。正面装置小室有效安装高度为72E(E=25mm)，经多功能板与后部电缆室隔离，充分利用了开关柜的安装空间，结构紧凑，单元配置灵活。后面电缆室带门，安装及维护方便。外型见图4。
进线柜的宽度按进线单元的框架电流确定，推荐宽度为400、600、800、1000mm，柜深1000mm。
Rear outlet switchgear structure
The cabinet rear outlet can reduce the width of the switch cabinet arrangement. The mainbus cable of the rear outlet switch cabinet is horizontally installed on the top of the switch cabinet. The rear half of the cabinet is a cable room. The incoming and outgoing cables are connected in the cable room at the rear of the cabinet. The front side of the switchgear cabinet is the device chamber, where the functional unit of the switchgear is installed. The system design moves the cable roomon the side of the switch cabinet to the back half cabinet, greatly reducing the arrangement width of the switch cabinet to further meet the requirements of the substation space layout.
The width of the feeder cabinet is 600mm, thedepth is 1000mm, and the topof thefeeder cabinet is an independent bus room, which isisolatedfrom the device room. The effective installation height of the front device chamber is72E(E=25mm), which is isolated from the rear cable room by the multi-function board, making full use of the installation space of the switch cabinet, compact structure and flexible unit configuration. The rear cable room has a door for easy installation and maintenance. The appearance is shown in Figure 4.
The width of the inlet cabinet is determined according to the frame current of the inlet unit. The recommended width is 400, 600, 800,1000mm, and the depth of the cabinet is 1000mm.
