A key for switchgear of high-voltage substation

Abstract

A key for a switch cabinet of a high-voltage transformer substation comprises a key body and a rotary handle. Threads corresponding to a door lock of the switch cabinet are arranged in the front end of the key body. The tail end of the key body is a hexagonal prism. The specifications of the hexagonal prism correspond to those of a hexagonal connector of an electric screwdriver. The top end of the hexagonal prism is provided with a sliding mounting groove. The two sides of the inner wall of the sliding mounting groove are provided with mounting locking concave points. The rotary handle is of a strip shape. The middle of the rotary handle is provided with a sliding mounting block. The shape of the sliding mounting block corresponds to that of the sliding mounting groove. The two sides of the sliding mounting block are provided with mounting locking convex points. The mounting locking convex points are connected with each other through an elastic component.

Description

technical field [0001] The invention relates to a key, in particular to a key used for a switch cabinet of a high-voltage substation. Background technique [0002] In the daily work of the substation, the switchgear needs to be frequently operated, so the door of the switchgear needs to be opened and closed frequently. Since the door locks of the switch cabinets are all screw-type door locks, the key needs to be rotated 8-10 times when opening. The existing ordinary key has a very small rotating torque, so it takes time and effort to open and close the operation. Affect the power transmission of users. Especially when it comes to bus stop and power transmission operations, many feeders are involved and a wide range of users is involved. It can quickly and reliably open and close the cabinet door, effectively improve the power transmission efficiency, and ensure the power consumption of customers. Contents of the invention [0003] The main technical problem to be solved ...
