摘要
当前电力公司大量配用户外柱上开关实现本地化远程控制,本文对其所安装的专用电压互感器在采用现场搭接连接的安装过程中,易使电压互感器发生烧毁事故的原因进行分析论述,并提出相应的改进意见或措施。
At present, many power companies have equipped a large number of outdoor column switches which have implemented localized remote control. This paper discusses the cause of voltage transformer burning in the installation process using on-site lap connections, and proposes corresponding improvement suggestions or methods.
