摘要
Abstract
There are various safety hazards in the three-phase inconsistency protection circuit of LW13A-550/Y type 500 kV split phase operation circuit breaker produced by Zhenxiong Company.The circuit breaker is in the closed state.When the three-phase is inconsistent and the outlet relay trips,or if it is accidentally touched or moved by human error,it will cause the circuit breaker to trip incorrectly.This article introduces how to efficiently solve the above-mentioned problems in a simplified optimization method based on the original circuit,effectively preventing the accidental tripping of circuit breakers during operation,and further improving the safety,stability,and reliability of network related equipment.关键词
