断路器防跳回路接线改进

随着变电站设计标准化的应用,断路器防跳功能由断路器本体机构实现,在变电站调试投运过程中发生运行操作和监视失效现象,给电网安全稳定运行带来事故隐患.文章介绍了在新建变电站中对保护装置内跳闸监视、合闸保持回路及一次机构箱内接线设计进行改进,避免了事故隐患,经实际运用收到良好成效,在增强设备运行稳定及保证电网安全方面发挥了积极作用.

Leap-preventive Circuit Improvement of Circuit Breaker

Aolng with the application of substation design standardization, the circuit breaker leap-preventive function implemented through its own structure, the operation and monitoring failure during substation debugging and putting into operation will induce hidden trouble for safe and stable operation of power grid. The paper introduces upgrading of the trip monitoring for protective device, switch on circuit and primary mechanism case internal wiring, thus avoids hidden trouble, and obtains favorable effect, it enstures equipment stable operation and power grid security.
