环境因素对12 kV充气柜可分离连接器绝缘性能的影响

open access: yesGaoya dianqi
文中旨在研究环境因素对12 kV充气柜可分离连接器绝缘性能的影响,同时为局放与化学融合检测法在12 kV充气式开关柜绝缘故障监测领域的应用提供实践依据。设计实验模型与实验方法,首先研究环境温、湿度对12 kV充气柜可分离连接器绝缘性能的影响,然后采用升高测试电压直至绝缘击穿的测试方式,加速模拟高湿度、高污秽、高盐度引发绝缘故障的发展过程,并采用电化学传感器对绝缘老化气体产物进行监测,研究绝缘击穿后绝缘材料裂解产物的变化规律。实验结果表明,高温、高湿环境以及高盐度条件均会降低12 ...
