带有试验开关的矿用隔爆型组合真空电磁起动器机械联锁机构设计Ⅱ

Mechanism Linking Device DesignⅡof Flame-proof Combined Vacuum Electromagnetic Starter with Test Switches for Mine

带有试验的开关的矿用隔爆型组合真空电磁起动器可以在隔离换向开关打在断开位即输出不带电的情况下对整机进行调试和试验,既安全,又方便。但这种起动器原设计的主要电器配件四个隔离换向开关垂直安装在壳腔的右侧,安装维修不甚方便。对此又设计了一种四个隔离换向开关横向按装壳腔顶部的组合真空电磁起动器。简要阐述该起动器的联锁机构。

The vacuum electromagnetic starter with test switches can adjust and test to the unit during the isolator change-over switch being open, that is output without electrictiy. They are both safe and convenient. However, four isolator change-over switches of the starter are vertically mounted on the right of the housing cavity, the installation and maintain are not convenient. For this reason, our company has desinged a starter with four isolator change-over switches of the housing cavity cross top. The paper sketeched the linking mechanism of the starter.
