低压隔离电器与保护电器及其应用中存在的几个问题

Some Problems in the Applications of LV Disconnector and Protective Apparatus

结合实例讨论了我国低压隔离电器、断路器及熔断器产品在工程应用中存在的某些不合理的甚至是错误的用法 ,导致运行维护困难、运行故障与事故增多 ,或留下长期的安全隐患。

Combined with practical examples, some inreasonable uses of LV electrical apparatus products(including disconnector, circuit breaker and fuse)in engineering applications were discussed.Some improvements were proposed.
