Automatic interlocking mechanism for isolation chamber doors of high-voltage switchgear
The invention discloses an automatic interlocking mechanism for isolation chamber doors of a high-voltage switchgear. The automatic interlocking mechanism comprises an ejecting rod and a return pin. The rear ends of the ejecting rod and the return pin are separately hinged to the two ends of a connecting rod. The middle part of the connecting rod is hinged to a connecting rod seat, and the connecting rod seat is fixed to the inner side of a box. A return pin spring is arranged between the return pin and the inner side of the box; the front end of the ejecting rod corresponds to the inner surface of a right door, and the front end of the return pin corresponds to a blind hole in the inner surface of a left door. When the right door is opened, the front end of the ejecting rod separates fromthe inner surface of the right door, and the front end of the return pin exits the blind hole in the inner surface of the left door; when the right door is closed, the inner surface of the right doorpushes the front end of the ejecting rod, the front end of the return pin is inserted into the blind hole in the inner face of the left door. The automatic interlocking and unlocking of the isolationchamber doors is realized by the return pin spring, the complexity of a locking mechanism is greatly reduced, the accuracy and feasibility of the operation are improved, and the safety performance isimproved. The automatic interlocking mechanism is suitable for the locking of the two adjacent isolation chamber doors.
本发明公开了一种高压开关设备隔离腔门自动互锁机构，包括顶杆和回位销，顶杆和回位销的后端分别与连杆的两端铰接，连杆的中部与连杆座铰接，连杆座固定在箱体内侧，回位销与箱体内侧之间设有回位销弹簧；顶杆的前端对应右侧门的内面，回位销的前端对应左侧门内面的盲孔。右侧门打开时，顶杆的前端脱离右侧门的内面，回位销的前端退出左侧门内面的盲孔；右侧门关闭时，右侧门的内面推动顶杆的前端，回位销的前端插入到左侧门内面的盲孔中。通过回位销弹簧实现隔离腔门的自动互锁解锁，很大程度上减小了闭锁机构的复杂性，提高了操作的准确可行性，增强了安全性能。适用于相邻两隔离腔门的闭锁。
