摘要
LW9-66型断路器需要具有较好的动作特性和灭弧性能。它执行断开电流的分闸操作和接通电流的合闸操作,出现故障的概率较大。因此,对断路器的故障分析及处理一直备受重点关注。通过阐述LW9-66型六氟化硫断路器的结构特点及工作原理,针对该断路器常见故障问题,分析其故障原因,并提出了日常维护工作中的重点。
The LW9-66 type circuit breaker needs better operating characteristics and arc extinguishing performance,it carries out the switching operation of breaking current and the closing operation of turning on the current, the probability of failure is large, so the fault analysis and treatment of the circuit breaker have been focused on. This paper describes the structure characteristics and working principle of LW9-66 sulfur hexafluoride circuit breaker, analyzes the causes of its faults, and puts forward the emphasis of routine maintenance work.
