Cable chamber door interlocking mechanism of armored movable metal-enclosed switchgear
The invention discloses a cable chamber door interlocking mechanism of armored movable metal-enclosed switchgear, and relates to the technical field of switchgears. The mechanism comprises a cabinet body, a grounding switch operating shaft, a cable chamber door, an interlocking mechanism and a propelling mechanism; the grounding switch operating shaft and the interlocking mechanism are both arranged in an inner cavity of the cabinet body, and the cable chamber door is hinged to the cabinet body; the propelling mechanism is mounted on the cable chamber door; the interlocking mechanism can limitthe rotation of the grounding switch operating shaft when the cable chamber door is in an open state, so the grounding knife switch is kept in a closed state. The propulsion mechanism can release thelimit of the interlocking mechanism on the operating shaft of the grounding switch, so that the grounding knife switch can be switched between a switching-off state and a switching-on state. The high-voltage switchgear cable chamber door can achieve the function that the high-voltage switchgear cable chamber door cannot be used for power transmission in an unclosed state, prevents an operator from entering an electrified interval by mistake, facilitates the improvement of the reliability and safety coefficient of a whole product, and is high in practicality.
本发明公开一种铠装移开式金属封闭开关设备电缆室门连锁机构，涉及开关设备技术领域，包括柜体、接地开关操作轴、电缆室门、连锁机构和推进机构，接地开关操作轴和连锁机构均设置于柜体内腔，电缆室门铰接于柜体，推进机构安装于电缆室门上；连锁机构能够在电缆室门处于开启状态时限制接地开关操作轴转动，使接地刀开关保持合闸状态；推进机构能够解除连锁机构对接地开关操作轴的限制，使接地刀开关进行分、合闸状态的转换。本发明可实现高压开关设备电缆室门在未关闭的状态下不能进行送电投用功能，防止作业人员误入带电间隔等现象，有利于提高整个产品的可靠性和安全系数，实用性强。
