35kV/10kV中置柜设备检修操作中验电接地的对策

Countermeasures of Checking Electric Grounding in the Equipment Maintenance Operation 35kV/10kV Cabinet

随着电网技术的发展,35kV/10kV设备已大量采用中置柜形式,例如10kV的KYN28(GZS1)型铠装中置式交流金属封闭开关设备。此类设备防爆等级高,操作方便,有较完善的防误闭锁功能,但其母线检修及线路电缆检修时验电和接地均不方便。文中根据工作实际,对此提出了相应对策。

With the continuous development of power grid, 35 kV/10 kV equipment Have been widely used in cabinets form, such ;is 10 kv KYN28 （GZS1） sheathed type AC metal-enclosed switching equipment. Such devices anti-explosion grade is high. easy to operate, has better anti blocking function by mistake. But it was not convenient when checking elec- tric and grounding in the bus maintenance and cable line maintenance. According to the actual, this paper put forward the counlermeasures.
