低压断路器的选型与应用

摘要

介绍了低压断路器在配电线路、家用及类似场所负载、电动机负载的选型方法,并分析了在断路器保护功能以及不同负载特性情况下的选型策略。通过对低压断路器的合理选型,使低压断路器达到最佳的保护状态,并避免了因断路器选型不当及安装不合理而造成的安全隐患。%Introduction was made to a low-voltage circuit breaker type selection method in distribution line, household use, similar sites load and motor loads. Analysis was made to type selection strategy under circuit breaker protection function and different load characteristics conditions. Reasonable type selection of low-voltage circuit breakers enables low-voltage circuit breakers to reach optimal protection status, so as to avoid safety dangers caused by unsuitable circuit breaker type selection and unreasonable installation.
