High-voltage power distribution cabinet pressure relief device based on Internet of Things technology

Abstract

The invention provides a high-voltage power distribution cabinet pressure relief device based on the Internet of Things technology, and relates to the technical field of high-voltage power distribution cabinet pressure relief. The device comprises an assembly frame, pressure relief plates and a U-shaped synchronous frame; two back shore plates are symmetrically arranged at the top of the assembly frame, and the assembly frame is fixedly mounted at a pressure relief assembly opening of the power distribution cabinet through bolts; the pressure relief plates are vertically installed in the assembly frame, and the upper ends and the lower ends of the pressure relief plates are connected with the adjacent pressure relief plates correspondingly; the U-shaped synchronous frame is connected with the pressure relief plate, and the U-shaped synchronous frame is connected with the assembly frame through an elastic belt; and the buffer column is connected to the top end of the U-shaped synchronous frame, and the top end of the buffer column is connected with the top end of the assembly frame. When the pressure relief plates are influenced by high-pressure gas to rotate and open, the pressure relief plates drive the U-shaped synchronous frame to lift, and the U-shaped synchronous frame drives the other three pressure relief plates to synchronously rotate and open, so that the high-pressure gas is discharged through the assembly frame, and the high-pressure gas is prevented from exploding and hurting people.

Description

technical field [0001] The invention belongs to the technical field of pressure relief for high-voltage power distribution cabinets, and more specifically relates to a pressure relief device for high-voltage power distribution cabinets based on Internet of Things technology. Background technique [0002] During the operation of the high-voltage power distribution cabinet, when a short-circuit fault occurs in the primary circuit due to short-circuit, insulation aging, and human improper operation, high-temperature and high-pressure gas will be generated instantaneously under high short-circuit current. The cabinet body is generally provided with a pressure relief port, and a pressure relief device is arranged on the pressure relief port. [0003] The pressure relief device of the high-voltage power distribution cabinet can refer to the CN209544876U patent, which mainly includes a high-voltage power distribution cabinet body. The top of the cabinet body is provided with a pres...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a high-voltage power distribution cabinet pressure relief device based on the Internet of Things technology to solve the problem that the pressure relief plate is difficult to open synchronously in a short time when the existing similar high-voltage power distribution cabinet pressure relief device is in use. As a result, the pressure relief of the power distribution cabinet is not complete enough. The high-pressure gas is easy to cause damage to the electrical components inside the power distribution cabinet, and the protection effect on the pressure relief plate is poor. The instantaneous high temperature and high pressure gas can easily cause damage to the pressure relief plate. After the pressure relief plate is used It needs to be repaired and dealt with, the waste is large, and the maintenance is relatively cumbersome.
