Gaoya dianqi机械性振动缺陷的检测是保证GIS设备安全运行的有效手段之一，尚缺乏针对GIS设备内部多种构件机械缺陷振动规律的系统性研究。文中研发了一套GIS设备振动状态高灵敏检测装置，搭建了高电压大电流GIS设备机械缺陷模拟平台，模拟出5种典型缺陷，开展了GIS设备振动信号特性试验研究。试验结果表明，在负载电流不变的情况下，电压的改变对振动信号基本没有变化；在同一电压作用下，振动信号波形保持基本不变，振动信号幅值随着负载电流增加而增加；机械缺陷情况下，振动信号主要频谱为100 Hz，并叠加了较多的高频成分 ...

Dianci bileiqi, 1989 约1.2万只带有机硅橡胶保护伞的聚合物绝缘子在高压线路上试运行4～5年后效果良好.在运行期间未发现机械的和电气的损坏,没有一条线路由于聚合物绝缘子的缘故而跳闸.从线路上卸下的绝缘子经试验后表明,它不存在机电特性下降的趋势.运行1～4.5年之后,自然污秽条件下的放电特性仍超过额定值,而机械特性为额定值的一倍半,其污层的表面电导率比玻璃绝缘子的小1/3～1/4.
