浅谈断路器在低压配电设计中的选用

The discussion of election to the opening circuit switch in low pressure distributed-electricity design

根据多年从事电气设计的经验,总结了选用低压断路器的原则,探讨了配电保护型断路器的选用和电动机保护型断路器的选用,并对断路器的分断能力进行了分析,指出正确使用断路器可以有效提高低压配电系统的运行性能。

Based on many years＇ experience working on electric design, the paper summaries to the principle of electing low pressure＇s opening circuit switch, and then discusses two kinds of eletion on the opening circuit switch, they are respectively electricity-distributed with protective function and electric motor＇ protective function. Meanwhile, it also analyzes the ability of opening circuit switch to distribute electricity. At last, points out that using the opening circuit switch appropriately can strengthen effectively the operating function of low pressure electricitydistributed system.
