Secondary screen cabinet of transformer substation
The invention belongs to the technical field of high-voltage electrical equipment, and discloses a transformer substation secondary screen cabinet which comprises a secondary screen cabinet door and a secondary screen cabinet body. The secondary screen cabinet door comprises a cabinet door body rotationally connected with a secondary screen cabinet body, an electromagnet used for adsorbing the cabinet door body or the secondary screen cabinet body, an elastic pushing piece used for pushing the cabinet door body and a self-locking unit, the self-locking unit comprises a traction piece, a fixing box and a connecting rod assembly rotationally connected with the fixing box, and the fixing box is connected with the secondary screen cabinet body. One end of the traction piece is connected with the connecting rod assembly, and when the elastic pushing piece pushes the cabinet door body to rotate outwards, the traction piece pulls the connecting rod assembly to rotate to the outer side of the cabinet door body so as to limit the cabinet door body from continuing to rotate outwards, and it is guaranteed that the secondary screen cabinet door can keep the locking state of the secondary screen cabinet body; failure of the secondary screen cabinet door caused by power failure or power failure is avoided, the stability of the secondary screen cabinet door is improved, and therefore the safety performance of the secondary screen cabinet of the transformer substation is improved.
本发明属于高压电器设备技术领域，公开一种变电站二次屏柜，变电站二次屏柜包括二次屏柜门和二次屏柜本体，二次屏柜门包括与二次屏柜本体转动连接的柜门本体、用于吸附柜门本体或二次屏柜本体的电磁铁、推动柜门本体的弹性推件以及自锁单元，自锁单元包括牵引件、固定盒以及与固定盒转动连接的连杆组件，固定盒与二次屏柜本体连接，牵引件的一端与连杆组件连接，弹性推件推动柜门本体向外转动时，牵引件拉动连杆组件转动至柜门本体的外侧，以限制柜门本体继续向外转动，保证二次屏柜门能够保持对二次屏柜本体的锁定状态，避免电力故障或断电导致二次屏柜门失效，提高二次屏柜门的稳定性，从而提高变电站二次屏柜的安全性能。
