Indoor combined high-voltage cabinet with built-in fireproof isolation structure

Abstract

The invention discloses an indoor combined high-voltage cabinet with a built-in fireproof isolation structure, and the cabinet comprises a cabinet bottom shockproof frame which is disposed at the bottom of a high-voltage cabinet body, fireproof plates are symmetrically connected to the inner walls of the left and right sides of the high-voltage cabinet body, a partition plate frame which is disposed at the rear side of the fireproof plates, and an equipment plate frame and an isolation plate frame are connected to the partition plate frame. And the front side of the equipment plate frame is provided with electrical elements and heat dissipation shutters which are symmetrically arranged on the high-voltage cabinet body and the fireproof plate. When the indoor combined high-voltage cabinet with the built-in fireproof isolation structure is used in a daily safe environment, the shutters can be kept open to keep air flow in the cabinet body so as to enhance the heat dissipation capability, the shutters can be isolated and closed in time when a fire disaster occurs inside and outside the cabinet body, and the fire extinguisher for flame-retardant air can be automatically started, so that the indoor combined high-voltage cabinet is convenient to use. Therefore, oxygen required by a fire ignition point is reduced, open fire is prevented from being generated, damage to the cabinet body is avoided, manual operation steps can be reduced, and the safety performance of the cabinet body is improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage cabinet equipment, in particular to an indoor combined high-voltage cabinet with a built-in fireproof isolation structure. Background technique [0002] High-voltage cabinet refers to the equipment that plays the role of on-off, control or protection in power system power generation, transmission, power conversion and consumption. High-voltage cabinets are generally used in power supply bureaus or substations, and are transported into low-voltage cabinets after being stepped down by transformers. After that, it is transported to each power distribution box again, and high-voltage cabinets are generally equipped with precision equipment such as instruments, automatic controls, motor magnetic switches, and various AC contactors. Therefore, high-voltage cabinets need to have good and stable fire protection capabilities. Prevent the normal operation of the equipment from being affected in case of...

Problems solved by technology

[0004] The object of the present invention is to provide an indoor combined high-voltage cabinet with a built-in fire-proof isolation structure, so as to solve the problem that the currently used high-voltage cabinets proposed in the above-mentioned background technology cannot isolate the cabinet body from the external environment in time when a fire occurs, and cannot Effectively isolate the air flow to prevent flames, which will easily lead to the problem of accelerated damage to the interior of the cabinet due to high temperature and smoke
