摘要

针对目前25 kV 受电弓存在的一些故障现象，提出了一种新型的25 kV 受电弓控制电路设计方案，该方案可实现受电弓降落自动将高压隔离开关断开，同时又具备远程控制隔离的功能，保持受电弓在降弓期间被隔离，并使隔离侧网压互感器不带电, 而且只有升弓指令时才能使高压隔离开关的闭合电磁阀得电。该方案简单，可靠。

Abstract

Aiming at the fault phenomenon of 25 kV pantograph, a novel pantograph control circuit scheme was proposed, whichbreaked high-voltage isolating switch automatically when pantograph fell with remote control insulation function and kept voltagetransformer insulation until the lift command arrived. The method is simple and reliable.
