设计说明Design description

技术说明

YRM-12全绝缘全封闭环网开关设备(标准化)安装在一个镀锌板框架上,开关单元在SF6气箱内，气箱由抗腐蚀和无磁性3mm厚不锈钢板制成。
SF6气箱是一个“密封压力系统”在正常工作环境下可运行20年。SF6气体正常工作时压力为0.03\~0.25Mpa。

气箱装有压力释放装置，当压力过高时，保证气体能从底部或后部释放。

开关单元

负荷开关采用同轴旋转双断点方式，通过同一操作孔与滑板配合进行动能操作，因此开关在任一时刻只能处于“合闸、分闸、接地”三种状态的其中之一，彻底避免误操作。

操作机构

开关的操作机构安装在气箱外的前部，经特殊工艺处理，防锈蚀，方便手动操作及维护，并很容易实现电动操作。

Technical description

YRM-12 fully insulated and fully enclosed main ring unit switchgear (standardized) is installed on a galvanized sheet frame with switchgear inside an SF gas tank made of corrosion-proof and non-magnetic 3mm-thick stainless steel sheet.

The SFgas tank is a“sealed pressure system”that can run for 20 years in normal work conditions. The SF6 gas normal operation pressure is 0.03\~0.25Mpa.

The gas tank is equipped with a pressure relief device to guarantee that the gas can be relieved from the bottom or the back when the pressure is too high.

◆Switchgear

The load switch with coaxial rotating double-breakpoint method is operated in a same operation hole and a same slide plate to carry out kinetic operation, so it can only be in one of the three states of “closing, breaking, grounding” at any time to prevent any error in operation.

Actuator

The switch actuator is installed in the front of the gas tank and is treated by special technique to be corrosion-proof, easy to operate and maintain manually or actuate electrically.

变压器/线路保护Transformer, line protection

YRM-12全绝缘全封闭环网开关设备(标准化)提供了两种变压器保护方式：负荷开关熔断器组合电器和具有继电器保护的断路器。

YRM-12 fully insulated and fully enclosed main ring unit switchgear (standardized) provides two types of transformer protection: load switch fuse appliance combination and circuit breaker with relay protection.

使用负荷开关熔断器组合电器模块

变压器保护为限流高压熔断器与负荷开关的组合。熔断器室将安装在一个位于单元前部独立的有闭锁的外壳后面。负荷开关使用弹簧储能机构，该机构可由熔断器撞针所触发。为了便于熔断器的更换，可以使用操作手柄来拆卸熔断器室的端盖。熔断器的跳闸机构前置，保证了整个系统的防水性能。

◆Use of load switch fuse appliance combination module

The transformer protectionis a combination of current-limiting high-voltage fuse and load switch.The fuse chamber will be installed on the back of an independent latching enclosure shell in the front of the unit. The load switch has a spring-loaded energy storage mechanism to be triggered by fuse firing pin.

To make it easy to replace a fuse, can remove fuse chamber cover by handle.
The fuse trip mechanism is in front to keep the whole system water-proof.

附件Accessories

◆真正满足需求的电缆室A cable chamber as required

电缆连接室空间大，套管为标准式设计，实现与所有欧式标准电缆插头的配合。

正常情况下每个负荷开关单元可接1\~3回出线，特殊设计型可接4\~6回出线。

真空断路器单元可接1\~2回出线。

The cable chamber is very large and bushing has a standard design to adapt to all European standard cable plugs. In normal conditions, each loadswitch unit can connect 1\~3 circuit outlets, or 4\~6 circuit outlets with a special design. The vacuum circuit breaker unit can connect 1\~2 circuit outlets.

压力释放装置Pressure relief device

压力释放装置与电缆室之间用金属板隔开，如气箱内压力过高时，装置内防爆膜片破裂，以释放压力。

The pressure relief device is separated from cable chamber by a metal plate. If the pressure in the gas tank is too high, the explosionproof diaphragm in the device breaks to relieve the pressure.

电动操作Electric actuation

对电缆开关单元与变压器单元手动操作机构是标准的方案。也可以选择安装电动操作机构。

电缆开关，真空断路器和接地开关都是通过位于前面板后面的机构进行操作的。对于所有开关和断路器，都可以通过操作手柄操作(标准配置)，或者可以配备马达操作机构(附件)。但是，接地开关只能手动操作，并且配置了具有关合故障电流能力的机构。电动操作机构很容易分期实现。

The manual actuator for cable switch unit and transformer unit is standard. An electric actuator is also available.

The cable switch, vacuum circuit breaker and grounding switch are operated by a mechanism behind front panel. All switches and circuit breakers can be operated by handle (standard configuration)or can be equippedwitha motorized actuator (accessory). However, a grounding switch can only be operated manually and is equipped with a mechanism capable of breaking due to faulty current. It is easy for an electric actuator to realize.

◆电缆连接Cable connection

选用国际标准通用规格套管符合DIN47636标准，便于用户选择相应的电缆附件。采用T形前、后电缆插头连接，欧式螺栓逐级坚固式结构。前插头与套管的连接采用M16螺栓。

The international standard universal specification bushing conforms to DIN47636 standard, so it is convenient for users to choose corresponding cable accessories. The T-shaped front or rear cable plug and European-style bolt step structure are adopted to connect and tighten. M16 bolt is used to connect a front plug with a bushing.

Fully insulated and fully enclosed main ring unit switchgear (standardized main ring unit)

联锁机构Interlocking mechanism

开关内部的联锁机构能有效防止误操作。并确保电缆室只有在开关处于“接地”状态，才能进入，并可加明锁，锁定在不同状态。

The interlocking mechanism inside a switch can effectively prevent any error in operation, and guarantee that a person only can enter the cable chamber when the switch is “grounded”, with a lock to lock it in any state

◆避雷器连接Arrester connection

负荷开关单元可加装T形后插式硅橡胶全密封金属氧化锌避留器。

当电缆回路数较多，空间不够时可采用π形后插式避雷器。

The load switch unit can be equipped with T-shaped rear-plug silicone rubber fully-sealed metal zinc oxide arrester.

When there are many cable circuits without sufficient space,π-shaped rear-plug arrester is available.

◆辅助开关Auxiliary switch

负荷开关、接地开关可根据需要配置能同步反映开关位置状态的辅助开关。

The load switch and grounding switch can be equipped with an auxiliary switch to show the switch position synchronously as required.

熔断器Fuse

YRM-12系列开关熔断器更换直接、简便。使断器置于绝缘管内。绝缘管位于SF的金属气箱内，这种设计有如下优点：

◆熔断器盖及密封装置在电场最弱部分

无导电物质能附在熔断器组件上

在SF6气体中的部分完全受保护

◆熔断器盖无需额外的绝缘

弹簧储能操作机构和联动跳闸装置保证负荷开关三相在任一相熔断器熔断时同时自动断开。

It' s easy to replace YRM-12 series of switch fuse. The fuse is in an insulation cartridge, which is in SF6 metal gas tank. This design has following advantages:

◆Fuse cover and sealing device are at the weakest part of the electric field

◆No conductive substance can attach to the fuse assembly

◆The part within SF6 gas is completely protected

Fuse cover does not require additional insulation

The spring energy storage actuator and linked tripping device guarantee that the 3-phase load switch trips automatically when the fuse of any phase breaks.
