Fireproof anti-seismic alternating-current low-voltage power distribution cabinet

Abstract

The invention discloses a fireproof shock-resistant alternating-current low-voltage power distribution cabinet which comprises a cabinet body. A high-voltage bottle is connected into the cabinet bodythrough bolts, a valve is connected to a bottle opening of the high-voltage bottle through threads, a connecting pipe is connected to the top of the valve through threads, and a fire-fighting spray head is connected to the end, away from the valve, of the connecting pipe through threads. A damping base is arranged at the bottom of the cabinet body, guide columns are connected to the outer wall ofthe bottom of the cabinet body through bolts, the bottoms of the guide columns penetrate through the outer wall of the top of the damping base to be welded with connecting plates located in the damping base, and guide rods are welded to the inner wall of the bottom of the damping base. Through the arrangement of the high-pressure bottle, the connecting pipe and the fire-fighting spray head, compressed carbon dioxide is contained in the high-pressure bottle, and the fire-fighting spray head is burst and opened at high temperature, so that the carbon dioxide in the high-pressure bottle is sprayed out from the fire-fighting spray head through the connecting pipe to extinguish fire in the cabinet body, and the fireproof effect of the power distribution cabinet is realized.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a fireproof and shockproof AC low-voltage power distribution cabinet. Background technique [0002] With the development of science and technology, the subway provides great convenience for people to travel. When the subway is running, its tunnel needs to use AC low-voltage power distribution cabinets to distribute power to the lighting system to improve the safety of the subway during operation. [0003] In the prior art AC low-voltage power distribution cabinet, when distributing power to subway tunnel lighting, the internal electrical appliances are prone to fire due to short circuit, causing internal electrical appliances to burn out, and the power distribution cabinet does not have anti-seismic effect, resulting in power distribution The electrical appliances inside the cabinet were damaged by the vibration generated by the subway. Therefore, it is urgen...
