摘要
高压断路器分合闸线圈在长期运行条件下,会受到温度、湿度、盐雾等环境因素的影响,其性能也会发生相应的劣化。采用湿热试验考察温度、湿度对252 kV断路器分合闸线圈的影响,采用交变盐雾试验考察温湿度及盐雾对252 kV断路器分合闸线圈的综合影响,研究了分合闸线圈在相应试验条件下的劣化情况以及分合闸线圈电流的变化情况。研究结果表明,在湿热环境下,252 kV断路器的分合闸线圈性能的劣化是一个突变过程,无法通过分合闸线圈电流进行反映;在盐雾环境下,252 kV断路器的分合闸线圈性能的劣化是一个非线性的加速过程。
Under long-term operating conditions,the performance of opening/closing coil of high voltage circuit breakers degrades due to the environmental factors such as temperature,humidity and salt spray.The damp heat test is used to simulate the effects of temperature and humidity on the opening/closing coil of 252 kV circuit breaker,and the alternating salt spray test is used to simulate the combined effects of temperature,humidity and salt spray on the opening/closing coil of 252 kV circuit breaker.The degradation of the opening/closing coil under the corresponding conditions and the change of the opening/closing coil currents are studied.The study results show that the degradation of 252 kV circuit breaker’s opening/closing coil under hot and humid environment is a process of rapid change,which cannot be reflected by the opening/closing coil currents,and the degradation of 252 kV circuit breaker’s opening/closing coil under salt spray environment is a nonlinear acceleration process.
