Description

一种固封极柱及真空重合器 技术领域
本发明涉及电力设备技术领域，特别涉及一种固封极柱及真空重合器。
背景技术
24kV户外真空重合器目前在国内以三相支柱式、L形进出线居多，电压、电流采样采用外置的电压互感器和电流互感器。造成成套设备体积庞大，造价较高，不满足上方安装空间受限的场合。现有技术中缺少一种小型化、低成本、可在上方安装空间受限的场合安装使用的固封极柱。
现有国内24kV户外真空重合器用固封极柱绝大多数是L形进出线，电压、电流采样采用外置的电压互感器和电流互感器。现有其它电压等级户外真空断路器所用固封极柱，有在进线侧和出线侧采用内置电压传感器的实例，进线侧内置电压传感器和出线侧内置电压传感器均放置在出线侧，进线侧内置电压传感器通过金属引线将进线侧电压引至出线侧。
由于电压互感器和电流互感器外置，造成现有技术体积庞大、造价较高。因为竖直进线和水平出线成L形，高压进线需要从竖直上方或斜上方引入，在上方安装空间受限的场合就不能直接安装使用。进线侧电压传感器放置在出线侧，导致其除了在合闸状态承受相对地电压外还要在分闸状态下承受较强的出线侧断口电压，而且电场不均匀系数也较大；使用高压引线，导致其浇注时定位、固定不稳，浇注质量较差，容易产生放电气隙。
