INDOOR HIGH VOLTAGE MOTORIZED EARTHING SWITCH JES15-D-12/31.5

JES15-D-12/31.5型户内高压电动接地开关（以下简称接地开关）是我公司根据市场需要设计开发的新型接地开关， 适用于户内3~12KV三相交流50（60）Hz的电力系统内和各型号高压开关柜配套使用，亦可作为高压电器设备检修时系统接地用。并能使用在无人值守和智能化变电站中。

JES15-D-12/31.5 indoor high-voltage eleCTric earthing switch is a new type of earthing switch designed and developed by our company according to the market needs. It is suitable for indoor 3-12KV three-phase AC 50(60) Hz power system and various types of high-voltage Switchgear supporting use. It can also be used for system grounding during maintenance of high-voltage electrical equipment. And can be used in unattended and intelligent substation.

该产品符合***标准GB1985-2004《交流高压隔离开关和接地开关》及IEC62271-102-2002。接地开关结构简单紧凑，重量轻，操作灵活，安装方便，动热稳定性好，并有可靠的电动操作，保持原中置式开关柜的连锁不变，已获得了***专利。

The product conforms to national standard GB1985-2004 "AC high voltage disconnector and earthing switch" and IEC 62271-102-2002. The earthing switch has the advantages of simple and compact structure, light weight, flexible operation, convenient installation, good dynamic and thermal stability, and reliable motorized operation.

由于接地开关为电动操作，因此中置柜上手动操作连锁与原来保持风格一致，但是有部分零件已作修改，务必使用本公司配套的连锁件，否则会使电动接地开关的电机烧毁。

As the earthing switch is electric operation, so the manual operation of the chain on the cabinet is consistent with the original style, but some parts have been modified, be sure to use the company's matching chain parts, otherwise the motor of the earthing switch will be burnt down.

 若中置柜后门需要与电动接地开关有相应的连锁时，也务必使用本公司专利技术生产的后门连锁机构，并装有行程开关，当后门未关闭时，切断电动接地开关的操作电源，以避免电动接地开关的误操作而损坏电机。

If the back door of the middle cabinet needs to have a corresponding interLock with the motorized earthing switch, it must also use our patented technology to install a backdoor interlock, and equip with a travel switch, when the back door is not closed, cut off the operating power of the motorized earthing switch, in order to avoid damage to the motor due to the wrong operation of the electric earthing switch.

与电动接地开关进行电气连锁时，务必使用相关联电气元件的辅助触点来断开电动接地开关的操作电源而实现电气连锁。以确保电气连锁的可靠性。

When connecting by electrical interlock with the earthing switch, be sure to use the auxiliary contacts of the associated electrical components to disconnect the operating power supply of the earthing switch to achieve electrical interlock. To ensure the reliability of the electrical interlock.
