Description

隔离开关与接地开关联锁操作机构
技术领域
本实用新型涉及一种电力设备，特别是一种隔离开关与接地开关联锁操作机构。
背景技术
部分高压开关设备中，由于结构原因隔离开关与接地开关之间为联动关系，即隔离开关合闸时接地开关自动分闸，隔离开关分闸时接地开关自动合闸。此种联动操作关系，不能在隔离开关分闸时，验电后再合接地开关。如果出线侧有倒送电时存在一定的安全隐患。
发明内容
本实用新型的目的就是为了避免背景技术中的不足之处，提供一种隔离开关与接地开关联锁操作机构。
为达到上述目的，本实用新型采用如下技术方案：隔离开关与接地开关联锁操作机构，它包括两组相对并呈上下分布的静触头、位于两静触头之间隔离开关刀片、拉杆、接地开关、接地开关轴、拐臂I、拐臂II和电磁锁，拉杆上端与拐臂I一端铰接，拐臂I另一端与隔离开关刀片中部铰接，拉杆下端和拐臂II左侧端铰接，拐臂II右侧端与机体铰接，所述接地开关轴左端与接地开关连接，其右端与拐臂II右侧端固定连接，所述电磁锁位于接地开关轴中部。
对于本实用新型的一种优化，所述拉杆下端设有长腰孔，拐臂II左侧端通过铰链销与长腰孔连接。
对于本实用新型的一种优化，拐臂II下方设有与机体连接的复位弹簧。
本实用新型与背景技术相比，具有结构简单，使用方便，隔离开关的分、合更安全可靠。
附图说明
图1是隔离开关与接地开关联锁操作机构的使用状态图I。
图2是隔离开关与接地开关联锁操作机构的使用状态图II。
具体实施方式
实施例1：参照图1和2。隔离开关与接地开关联锁操作机构，它包括两组相对并呈上下分布的静触头1、位于两静触头1之间隔离开关刀片2、拉杆4、接地开关8、接地开关轴7、拐臂I 3、拐臂II 5和电磁锁9，拉杆4上端与拐臂I 3一端铰接，拐臂I 3另一端与隔离开关刀片2中部铰接，拉杆4下端和拐臂II 5左侧端铰接，拐臂II 5右侧端与机体铰接，所述接地开关轴7左端与接地开关8连接，其右端与拐臂II 5右侧端固定连接，所述电磁锁 9位于接地开关轴 7中部。所述拉杆4下端设有长腰孔4a，拐臂II 5左侧端通过铰链销与长腰孔4a连接。拐臂II 5下方设有与机体连接的复位弹簧6。
