摘要
起重机供电电源断错相保护功能的常规检验方法较为烦琐,有时还可能影响检验结果的正确判断.设计一种供电电源断错相自动切换装置用于断错相保护功能的检验,以降低劳动强度、提高检验效率,并有效保证检验结论的正确性.
The conventional inspection method of the fault phase sequence protection function of power supply of Crane is more cumbersome,and sometimes it may affect the correct judgment of the test results.An automatic fault phase sequence switching device for power supply is designed for the inspection of the fault phase sequence protection function to reduce labor intensity,improve inspection efficiency,and effectively guarantee the correctness of inspection conclusions.
