可带电分断电压的接线端子排
本专利技术涉及一种可带电分断电压的接线端子排。
技术介绍
接线端子排是电气设备中用来连接线路的一种电气元器件,接线端子排的材质、种类、连接方式等不断推陈出新,使用的场合越来越广,越来越便捷,功能越来越强大,但接线端子排设计普遍考虑的是电路的连接,很少考虑带电压分断,目前,带电电压分断应用较多的仅有滑块式端子排可实现接线端子排的带电分断。滑块式端子排的带电分断也存在一定的缺陷,一是带电分断需要拧松导电滑块固定螺丝,带动滑块向进线侧滑动,过程较费时间,碰到进线侧与负载侧滑轨错位,滑块无法向进线侧滑动,就无法实现电压的分断;二是松动滑块固定螺丝和向端子排进线侧移动滑块过程是带电作业,滑块固定螺丝拧动太松或松动不够,移动滑块过程容易用力不当,易引发事故。电力系统重要输电、配电设备的继电保护、计量等负载电压回路发生故障,在线处理风险太高,可能会造成检修人员触电伤害和电压回路短路事故,这就需要在电压回路找一个可靠的分断点,而接线端子排是首选,但现有接线端子排,即便是滑块式端子排也存在着上述问题,因此如何在确保检修人员作业安全的情况下对电压故障负载实 ...
