Five-prevention lock rain-proof box used on transformer substation mechanism box

Abstract

The invention relates to a five-prevention lock rain-proof box used on a transformer substation mechanism box. The five-prevention lock rain-proof box used on the transformer substation mechanism boxcomprises a box body, an elastic cover and a spring lock catch structure; a lock groove is formed in the top of the box body; the elastic cover is arranged at the upper part of the lock groove; a through hole is formed in the side surface of the box body; the spring lock catch structure comprises a button; the button penetrates through the through hole in the box body and is arranged on the side surface of the box body; and the spring lock catch structure is arranged in the box body and is connected with the elastic cover. According to the five-prevention lock rain-proof box used on the transformer substation mechanism box, with the adoption of the box body, the elastic cover and the spring lock catch structure, closed storage of a five-prevention lock is achieved, the problem that the five-prevention lock is affected by rain in the long term is solved effectively, and the operating schedule of power outage work and power supply work is ensured.

Description

technical field [0001] The invention relates to the field of electric safety protection devices, and more specifically, relates to a five-lock-proof rainproof box used on a substation mechanism box. Background technique [0002] The five-proof mechanical program lock is mainly used in the switching operation of the power system in the substation to force the operators to operate in accordance with the power operation rules and procedures. Five-proof mechanical locks are widely installed in the substations of the power system. In addition to mandating the operation process of operators, it can also avoid misoperation during the operation: 1. Prevent the switch from being pulled and closed by mistake; 2. Prevent load distribution 3. Prevent the live wire from being connected to the ground wire; 4. Prevent the ground wire from closing the isolation knife switch; 5. Prevent mistakenly entering the charged interval. Therefore, the mechanical program lock is also called "five-pro...
