摘要
利用化学成分检测、微观形貌检测、金相检测、力学性能检测及断口形貌分析等试验方法,对某10 kV全封闭隔离开关断裂原因进行了分析,得出该隔离开关转轴存在大量的气孔是断裂的主要原因.此外,为防止再次出现隔离开关断裂故障,提出了针对性的建议.
Abstract
The fracture reason of a 10 kV fully enclosed isolation switch was analyzed by means of chemical composition detection,microscopic morphology detection,metallographic detection,mechanical properties detection and fracture morphology analysis.It was concluded that the main reason for the fracture was the existence of a large number of pores in the rotating shaft of the switch.In addition,in order to prevent the failure of the isolation switch from happening again,specific suggestions are put forward.
