摘要
LTB245E1型断路器为220 kV SF_6断路器,配置BLK222型弹簧操动机构,目前广泛应用于四川电网中。通过对一起该型断路器弹簧机构缺陷原因的分析,就LTB245E1-BLK222型断路器检修工作重点及对策进行了探讨,以预防电气故障的发生。
LTB245 E1 circuit breaker is a widely used switch equipment in electric power enterprises currently. It is the 220 kV SF_6 circuit breaker produced by Beijing ABB Company, which is equipped with BLK222 spring operating mechanism. A typical fault of spring operating mechanism is analyzed. In order to prevent the electrical faults, the focus of the repair work and countermeasures are discussed.
