摘要
针对220kV大港变电站在验收110kV线路时断路器控制回路中出现的问题,简单分析了电力系统中保护装置防跳与断路器机构防跳的原理及其在控制回路参数配合上出现的异常现象,并在此基础上,探讨了可能的解决方案及其优缺点,并最终给出较为成熟和经济的改造方案。
For the problem of the circuit breaker control loop of 110 kV line of Dagrang 220 kV substation acceptance,the unusual phenomenon of the principle and its control loop parameter match of the protector antitrip and circuit breaker mechanism antitrip in the power system has been analyzed. And on the basis of this,discuss the plan to be solved and strong and weak points. Finally gioe out improved plan.
