Description

箱式变电站内高压柜室和变压器室的互锁装置
技术领域
本实用新型涉及一种箱式变电站，尤其是箱式变电站内高压柜室和变压器室的互锁装置。
背景技术
现有的箱式变电站内高压柜室和变压器室的互锁装置都是采用电磁锁结构，其存在的不足是电磁锁闭锁可以人为强制解锁，安全性不够。
发明内容
本实用新型的发明目的是为了解决现有箱式变电站内高压柜室和变压器室的互锁装置存在的上述不足，提供一种结构新颖，安全性高的箱式变电站内高压柜室和变压器室的互锁装置。
为了实现上述的发明目的，本实用新型采用了以下的技术方案：箱式变电站内高压柜室和变压器室的互锁装置，包括熔断器组合电器、接地开关轴、钢缆绳、插销和门扣，熔断器组合电器安装在高压柜室内，门扣安装在变压器室的门上，接地开关轴与熔断器组合电器相连，接地开关轴通过钢缆绳连接插销，插销处于变压器室内且与门扣匹配。
作为优选，还包括两个安装片，所述插销安装在两个安装片上，两个安装片与门扣处于同一直线上，两个安装片之间的插销上套接弹簧，插销在两个安装片上左右移动实现与门扣的打开和锁合，弹簧起到复位作用。
作为优选，所述接地开关轴上安装转盘，钢缆绳一端固定在转盘上，另一端连接插销。
采用了上述技术方案的箱式变电站内高压柜室和变压器室的互锁装置，熔断器组合电器带动接地开关轴旋转，控制钢缆绳上的插销动作，即插销锁住门扣或者打开实现变压器室的门锁或开。该箱式变电站内高压柜室和变压器室的互锁装置采用机械锁合的方式，具有结构新颖，安全性能好的优点。
附图说明
图1：本实用新型的实施例结构示意图。
具体实施方式
下面结合附图1对本实用新型做进一步描述。
如图1所示的箱式变电站内高压柜室和变压器室的互锁装置，包括熔断器组合电器10、接地开关轴9、钢缆绳7、转盘8、插销4、弹簧5、门扣3和两个安装片6。熔断器组合电器10安装在高压柜室2内，门扣3安装在变压器室1的门上，接地开关轴9与熔断器组合电器10相连，接地开关轴9上安装转盘8，钢缆绳7一端固定在转盘8上，另一端连接插销4，插销4处于变压器室1内且与门扣3匹配。插销4安装在两个安装片6上，两个安装片6与门扣3处于同一直线上，两个安装片6之间的插销4上套接弹簧5，插销4在两个安装片6上左右移动实现与门扣3的打开和锁合，弹簧5起到复位作用。
使用时，高压柜带电，安装在高压柜室2内的熔断器组合电器开关10经手动闭合输出高压电，熔断器组合电器10上的接地开关轴9旋转，套在接地开关轴9上的转盘8转动，带动钢缆绳7及插销4向门扣3方向移动，直至插销4卡住门扣3将变压器室1的门锁住，实现了在变压器带电运行时变压器室1的门不能开启。当熔断器组合电器10手动断开时，熔断器组合电器10上的接地开关轴9反方向旋转，带动钢缆绳7上的插销4脱离门扣3，此时才可以打开变压器室1的门，从而保护了人身安全。
