冶金起重机定子异常失电保护功能检验方法探讨

Explore Test Method about Abnormal Power Failure Protection of Forward and Reverse Contactors Control Crane Stator

带正反向接触器控制的起重机定子异常失电保护功能的检验,传统检验方法容易产生电弧,引发火灾和爆炸,存在一定的安全隐患。结合检验实践,提出了动力电路和控制电路分开独立检验的方法,提高了检验的安全性和有效性。

For the inspection of metallurgical crane stator abnormal power failure protection function with forward and reverse contactor control,the traditional inspection method is easy to generate arcs, cause fire and explosion, and there are certain safety risks.The author puts forward an independent test method of power circuit and control circuit, and analyzes the electrical diagram and the specific test method.The practice shows that the method improves the safety and effectiveness of the test.
