低压断路器一些可调参数的整定

Some Adjustable Parameters Setting of Low Voltage Circuit Breaker

介绍了基于两级低压配电系统中的各级断路器应具有的保护功能,讨论了各断路器过电流脱扣器的参数整定基本原则,并列出具体整定实例。结果表明,通过正确的参数整定,可以有效提高低压配电系统的运行性能,保证两级低压配电系统的稳定运行。

Based on two-level low voltage distribution system,the protective functions that each circuit breaker should have were introduced.The basic principles of over-current tripping device parameters setting were discussed and specific setting examples were listed.The results show that the operating performance of low voltage distribution system is highly improved through parameters setting to insure stable running of two-level low voltage distribution system.
