一种级联式高压开关柜局部放电定位方法

Gaoya dianqi
针对高压开关柜局部放电定位技术存在误差大、效率低、难以实现定位到柜的问题，文中基于开关柜中局部放电TEV信号进行了定位技术研究，提出了TEV传感器级联式定位方法。通过分布式传感器有线级联的方式、双母线分时比较方法与TEV传感器状态开关切换策略，使单个双通道采集卡能对多面开关柜上的TEV传感器信号脉冲进行采集比较，从而快速、高效、准确地在成排高压开关柜中定位出局部放电源所在的开关柜。基于该方法设计了高压开关柜局部放电级联式定位系统，采用总线级联式的模块化设计 ...

2000m海拔35kV开关柜母排结构安全净距试验研究

Gaoya dianqi, 2013
35 kV开关柜母排相间、相对地保证安全的空气距离是在1 000 m以下海拔通过对棒—板间隙的试验得出,棒—板间隙结构与开关柜内部母排结构存在差异,同时高海拔地区大气压力降低,空气间隙放电变得容易,为了得到2 000 m海拔35 kV开关柜的安全净距,文中对开关柜内母排结构进行了分类并设计了模拟试验开关柜,对不同结构母排进行了2 000 m海拔的工频及冲击放电试验。试验通过对不同结构母排施加标准要求的试验电压值,得到相对应的最小不放电距离即安全净距,为2 000 m海拔开关柜的设计、制造提供了参考。

高压开关柜抗电弧强度

Gaoya dianqi, 1979
高压开关柜内部发生电弧短路时,电弧持续燃烧放出的能量可能造成严重破坏,本文综述了开关柜(特别是封闭式开关柜)内发生电弧短路时承受的电动力及其运动规律,柜内气压及温度变化等一系列物理过程,并指出能限制其破坏范围的措施。
