最近，笔者参加了一起机破分析。这起机破是因电流互感器二次线圈回路开路而造成的。由于这种故障很少发生，且后果较为严重，故对这起机破做一剖析，并谈点防范措施。一、机被的起因和损失概况酿成这起机破的原因是电流互感器二次线圈即副边绕组，与531、532、523号导线连接处 Recently, I participated in a machine broken analysis. This breakage is caused by the open circuit of the secondary coil of the current transformer. Because this kind of trouble rarely occurs, and the consequence is more serious, so this machine break makes an analysis, and talk about preventive measures. First, the machine was the cause of the loss and loss led to the cause of this broken machine is the secondary coil current transformer secondary windings, and 531,532,523 leads at the junction
