摘要
针对某企业发生的变压器保护动作跳闸失电故障,通过对变压器失电原因的分析,确定了此次变压器失电是控制电缆故障引起的保护误动作。利用精密诊断技术准确定位了故障点并进行绝缘修复处理,快速恢复了系统正常供电。
The paper addresses a transformer protection tripping and power loss fault in an enterprise.Through analysis of the causes of the transformer power loss,it was determined that the fault was caused by a control cable fault leading to a protection misoperation.Using precise diagnostic technology,the fault point was accurately located,and insulation repair was performed,quickly restoring normal power supply to the system.
