摘要
三相低压供电系统零线断线及施工误接线经常造成电压偏移而导致大面积烧毁用户用电器的事故,给国家和用户造成经济损失。为避免该类事故的发生,采用新型的具有保护零线断线保护功能的断路器是非常有益的。
Zero conductor broken and wire connection wrongly of the three-phase low pressure power supply system can cause voltage inaccurate and lead to accident of electrical apparatus are burned.In order to avoid this kind of accident,the using of new circuit breaker with protection function of zero curve broken is extremely beneficial.
