摘要
ZN18系列真空断路器合闸线圈为短时工作制线圈,由于构成合闸回路的元件多,若维护不当或不到位,使用运行中出现合闸线圈烧坏和面临烧坏的情况时有发生,所以对其各种故障原因加以分析,便于确保ZN18真空断路器的正常工作运行。
The Closing Solenoid of ZN18 vacuum circuit breaker works in temporary duty.The control circuit is made up of many components.Improper maintenance often leads to the Closing Solenoid burnt out or approaching to burn out.To identify the damaged causes of the Solenoid will improve the reliable performance of ZN18 vacuum circuit breaker.
