真空断路器操作过电压试验分析及其防护

Operation Overvoltage Test Analysis and Protection of Vacuum Circuit Breaker

真空断路器操作感性负载引起的操作过电压的危害越来越受到关注,文章通过试验对真空断路器操作感性负载产生的过电压进行分析,并提出六柱避雷器防护措施,可有效防护真空短路器操作时产生的相间及相对过电压,保证变压器、电感、电动机等设备的安全运行。

The hazards of operating overvoltage caused by vacuum circuit breaker operating inductive loads have attracted more and more attention.The overvoltage generated by the vacuum circuit breaker operating the inductive load was analyzed through the test.The six-pole lightning arrester protection measures was proposed,which could effectively protect the phase-to-phase and relative over-voltages generated during the operation of the vacuum short-circuit device,and ensured the safe operation of transformers,inductors,motors and other equipment.
