摘要
针对现场运行低压电力集中器的故障情况,对低压电力集中器元器件工作原理、电路结构、元器件的测试情况进行分析,认为雷击产生的瞬时过电压是造成本次故障的主要原因,并提出处理措施和改造建议。
For the failure of low voltage power concentrator,this paper analyzes the low voltage power concentrator com-ponents works principle, circuit structure, components andcomponents testing, considers that the lightning generatedtransient overvoltage is the main reasons for this failure, pro-poses treatment measures and transformation recommenda-tions.
