摘要
以典型的电气事故为引子,实例分析常规和智能型塑壳断路器在农村低压总保护中存在的缺点和不足。结合农村公用配电变压器低压总保护范围大且广的特点,提出了解决问题的设想和思路,以期为设计人员和使用者提供参考。
The shortcomings and deficiencies of the conventional and intelligent moulded case circuit breaker（MCCB） in the total protection of rural low-voltage were analyzed,by taking a typical electrical accident as a prel-ude.Combining the large and wide characteristizes of the rural public distribution transformer for low-voltage main protection,the ideas to solve problems were put forward,with a view to provide reference for designers and users.
