摘要
随着变电站智能运维的推进,各电力公司均在试点电气设备程序化操作,如对刀闸电机电源实施长投,则存在带负荷分合隔离开关的风险,难以承受。选择在运行刀闸电机回路中设置防止带负荷拉刀闸的二次联锁回路,则技术改造太大,回路复杂,运行管理困难。鉴于此,本文提出了几种实现变电站刀闸电机电源远方遥控的详细技术路线,并论证推荐了最优方案。
With the promotion of intelligent operation and maintenance of substation,all power companies are experimenting with the programmed operation of electrical equipment.If the power supply of knife switch motor is put into operation for a long time,there is a risk of disconnecting switch with load,which is hard to bear.If we choose to set up the secondary interlock circuit in the motor circuit of the operating knife switch to prevent the knife switch with load,the technical transformation is too large,the circuit is complex,and the operation management is difficult.In view of this,this paper puts forward several detailed technical routes to realize remote control of knife switch motor power supply in substation,and demonstrates and recommends the optimal scheme.
