Problems solved by technology

[0003] When the power cabinet is working, a lot of heat will be generated inside, and there are too many internal circuits. In some special cases, the circuit aging and short circuit will cause internal heating and generate a lot of smoke, and then internal combustion, which is extremely prone to explosion.
[0004] In the prior art, there is a lack of conventional components for the explosion-proof of the power cabinet, and a pressure detection device is generally used, but it only has a monitoring effect for the explosion-proof, and its explosion-proof effect is limited

Embodiment 1

[0032] see Figure 1~3 , in an embodiment of the present invention, an electric automation explosion-proof power cabinet includes a housing 1, a gas leaking mechanism and a detection mechanism, the gas leaking mechanism includes a vent 3 provided through the upper end of the housing 1 and connected by a fuse connection assembly 5 On the explosion-proof upper cover 6 at the upper end of the housing 1 , the detection mechanism is electrically connected with the fuse connection assembly 5 .

[0033] The lower part of the housing 1 is horizontally connected with a mounting plate 2, and the mounting plate 2 is fixed on the inner wall of the housing 1 by riveting or welding, and the surface of the mounting plate 2 is evenly distributed with air holes; the housing The two sides of the lower end of 1 are symmetrically provided with anti-skid support pads; the front of the housing 1 is hingedly connected to be provided with a cover door 10 that is split apart, and the lower part of the...

Embodiment 2

[0039] see Figure 4~5, in an embodiment of the present invention, an explosion-proof power cabinet for electrical automation, on the basis of Embodiment 1, the fuse connection assembly 5 is a cavity structure, and a sliding rod 51 is slidably arranged in the fuse connection assembly 5, so The bottom of the sliding rod 51 is a disc-shaped protrusion that is slidably fitted in the fuse connection assembly 5, the upper end of the slide rod 51 slides through the fuse connection assembly 5 and the end is fixedly connected with the sealing ring 7; The lower end of the sliding rod 51 and the inner bottom of the fuse connection assembly 5 are elastically connected by a compression spring 52, the compression spring 52 is in a compressed state, and the middle part of the lower end of the fuse connection assembly 5 is also assembled and connected with a fuse bolt 53. The lower end of the fuse bolt 53 slides through the lower end of the fuse connection assembly 5 and is embedded and fixe...

Abstract

The invention discloses an electrically automated anti-explosion power cabinet, which comprises a shell, an air leakage mechanism and a detection mechanism, wherein the air leakage mechanism comprisesa ventilation opening and an anti-explosion upper cover; the ventilation opening penetrates through the upper end of the shell; the anti-explosion upper cover is connected to the upper end of the shell through fusion connecting components; and the detection mechanism and the fusion connecting component are electrically connected. Compared with a door which is connected through a common hinge to rotate in the prior art, the opening way disclosed by the invention is stable, a rotation angle can be easily fixed, a wrong opening problem is not likely to happen, and equipment in the shell can be more favorably protected. When the problems of short circuit and the like internally happen, the detection mechanism controls the fusion connecting components to fuse to form the segmented rise of theupper cover, so that the ventilation and the breathability of the ventilation opening are guaranteed, and explosion is avoided.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to an explosion-proof power cabinet for electrical automation. Background technique [0002] With the increasing number of electrical appliances in life, a lot of manual labor has been replaced by electronic equipment, and the stability of power needs to be guaranteed by qualified equipment. The power cabinet is a commonly used power infrastructure, which houses a large number of power components. [0003] When the power cabinet is working, a lot of heat will be generated inside, and there are too many internal circuits. In some special cases, the circuit aging and short circuit will cause internal heating and generate a lot of smoke, and then internal combustion, which is extremely prone to explosion. [0004] In the prior art, there is no conventional component for the explosion-proof of the power cabinet, and a pressure detection device is generally used, but it only has a mo...
