Overheating self-opening type power cabinet based on thermal bimetal

Abstract

The invention, which relates to the technical field of power cabinets, provides an overheating self-opening type power cabinet based on thermal bimetal. The overheating self-opening type power cabinetcomprises a cabinet frame. A cabinet door is rotatably connected to the front side of the cabinet frame; a lock shell is fixedly mounted at one side, close to the cabinet frame, of the cabinet door;and a lock cylinder is slidably connected to the left side of the lock shell. A limiting frame is fixedly mounted at the left side of the lock shell at the inner side of the cabinet frame; a mountingframe is fixedly mounted at the bottom end of the limiting frame; and a cylinder is fixedly mounted in the mounting frame. According to the overheating self-opening type power cabinet, the limiting ofthe cabinet door can be released and the cabinet door can pop up automatically, so that the fire in the power cabinet can be extinguished effectively and quickly and thus much more time is bought forthe fire extinguishment of the power cabinet; and with a self-opening mechanism of the power cabinet, the cabinet can be reused after fire control, so that the cost is saved and the power cabinet isrepaired conveniently.

Description

technical field [0001] The invention relates to the technical field of power cabinets, in particular to an overheated self-opening power cabinet based on thermal bimetal. Background technique [0002] Power cabinet, also known as power distribution cabinet, can be divided into power distribution cabinet and lighting distribution cabinet. It is the final equipment of power distribution system and the general name of motor control center. The electric energy of a certain circuit of the upper-level power distribution equipment is distributed to the nearby loads, and the loads are protected, monitored and controlled. [0003] In the power cabinet, there will be complicated wiring and more wire ends. Therefore, when the circuit is short-circuited, the power cabinet is also the most vulnerable to damage. When a fire occurs inside the power cabinet, due to high temperature and current leakage, people It is impossible to open the cabinet door manually, so that it is impossible to e...

Problems solved by technology

[0003] In the power cabinet, there will be complicated wiring and more wire ends. Therefore, when the circuit is short-circuited, the power cabinet is also the most vulnerable to damage. When a fire occurs inside the power cabinet, due to high temperature and current leakage, people The cabinet door cannot be opened manually, and thus the fire inside the power cabinet cannot be effectively extinguished. Although the traditional self-opening power cabinet can unlock the cabinet door in the event of a fire, it cannot pop the cabinet door open and still Tools are needed to turn and open the cabinet door, which takes a certain amount of time, and the trigger devices inside some self-opening power cabinets are designed for one-time use, and cannot be used after being opened once. costly and time consuming
