摘　　要：为避免双电源切换过程中相位不对造成的事故,双电源线路或设备在投运前均须进行核相。传统低压母线槽核相工作是由3人利用万用表完成,其弊端是核相人员离母线槽裸露部分较近,容易造成触电事故,且效率低。文章介绍一种新型低压母线槽核相器,可实现2人在安全距离内完成核相,有效提升工作质效。Avoiding accidents caused by phase mismatch during the switching process of dual power sources is a goal that the power system operation department always pursues.Therefore,dual power lines or equipment need to undergo phase verification before being put into operation.The traditional low-voltage bus duct core phase work is completed by three people using a multimeter.The disadvantage is that the core phase personnel are relatively close to the exposed part of the bus duct,which can easily cause electric shock accidents and relatively low efficiency.This article introduces a new type of low-voltage bus duct core phase transformer,which can achieve two people to complete the core phase within a safe distance,effectively improving work quality and efficiency.
