Mobile power distribution cabinet with buffering housing of double-layer structure

Abstract

The invention relates to the technical field of power equipment, in particular to a mobile power distribution cabinet with a buffering housing of a double-layer structure. The power distribution cabinet comprises the housing, first sliding slots are symmetrically formed in the top of an inner cavity of the housing, first springs are connected to the opposite sides of first sliding blocks, a baseplate is slidingly connected to the bottom of the inner cavity of the housing, and fourth springs are connected to the portions, at the bottoms of inner cavities of displacement boxes, of the lower endsof sliding blocks. An electric power cabinet body is arranged in an inner box; semiconductor refrigeration chips are disposed symmetrically on the outer side of the electric power cabinet body; a temperature sensor, a PLC and a refrigeration compressor are sequentially disposed in the middle of the bottom of the inner cavity of the housing; a diversion tube is communicated with the upper end of the refrigeration compressor through connecting tubes to form a circulation loop. Compared with the prior art, the power distribution cabinet has the advantages of not only buffering and protecting electronic components in the power distribution cabinet but also achieving a good heat dissipation function, and the service life of the power distribution cabinet can be prolonged.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a mobile power distribution cabinet with a double-layer buffer shell. Background technique [0002] The power distribution cabinet is the final equipment of the power system. The power distribution cabinet is the general name of the motor control center. It is often used in occasions where the load is relatively scattered and the circuit is less. The power distribution cabinet is a cabinet made of steel to protect the normal operation of circuit components. It is widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. [0003] When the existing power distribution cabinet is in use, once a foreign object hits the cabinet body, it will have a great impact on the internal electrical components and circuits, and cannot form a good pro...

AI Technical Summary

Problems solved by technology

[0003] When the existing power distribution cabinet is in use, once a foreign object hits the cabinet body, it will have a great impact on the internal electrical components and circuits, and cannot form a good protection for the electrical components inside the power distribution cabinet. In addition, the existing The power distribution cabinet cannot effectively dissipate heat. The power distribution cabinet will generate a lot of heat during operation. This heat will affect the normal operation of the internal equipment and circuits of the power distribution cabinet. In severe cases, it may even cause a fire due to overheating of the equipment.
