Embodiment Construction

[0015] The present invention will be further described below with reference to specific embodiments.

[0016] refer to figure 1 , a key for high-voltage substation switch cabinets, comprising a key body 1 and a rotary handle 2;

[0017] The front end 11 of the key body 1 is provided with threads corresponding to the switch cabinet door lock; the tail end 12 of the key body 1 is a hexagonal prism, and the specifications of the hexagonal prism are the same as the hexagonal interface of the electric screwdriver. Correspondingly; the top end of the hexagonal prism body is provided with a sliding installation groove 13, and the two sides of the inner wall of the sliding installation groove 13 are provided with installation locking concave points 14; in this embodiment, the cross section of the sliding installation groove is convex. Chute. After this arrangement, the position is limited in the horizontal direction by the installation locking concave point, and the position in the ...

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 for a switch cabinet of a high-voltage substation. Background technique [0002] In the daily work of the substation, the switch cabinet needs to be operated frequently, so it is necessary to open and close the cabinet door of the switch cabinet frequently. Since the door locks of the switch cabinet are all screw-type door locks, the key needs to be rotated 8-10 turns when opening. The existing ordinary key has a small rotation torque, so it is time-consuming and laborious to insist on opening and closing operations. Affect the user's power transmission. Especially when it comes to the operation of bus stop and power transmission, there are many feeders involved and a wide range of users. The cabinet door can be opened and closed quickly and reliably, which can effectively improve the power transmission efficiency and ensure the power consumption of customers. SUMMARY OF THE INVENTION [0003] ...
