国外新一代塑壳断路器的现状和发展动向

Status and Developing Trend of New Generation of the Moulded-Case Circuit Breakers Abroad

介绍了近年来国外著名电气公司开发的新一代塑壳断路器(如双断点触头系统、电子脱扣器、可通信断路器、接地故障保护和剩余电流保护等)及其技术指标、产品结构特点和技术发展方向,对国外塑壳断路器的发展进行了全面的阐述。

The new generation of moulded case circuit breakers developed by main electrical companies abroad was introduced in the recent years, and their technical parameters, the feature of structure of the products, the developing trend of technology, for example double-gap contacts system, electronic release, communication-capable circuit breaker, earth-fault protection and residual current protection etc. were expatiated, so as the development of the moulded case circuit breakers abroad was introduced completely.
