Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a closed type high and low voltage power distribution cabinet suitable for multiple places, which overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and aims to solve the problems of the existing high and low voltage power distribution cabinets. When the airtight function is equipped, the heat generated by the operation of the internally installed electrical components cannot be dissipated in time, so that the electrical components work in a higher temperature environment. On the one hand, it is easy to cause the electrical components in the cabinet to age. Problems that cause electrical components to burn out

Embodiment 1

[0035] A closed high and low voltage power distribution cabinet suitable for multiple places, including a power distribution cabinet body 1 and a base 4 installed at the lower end of the power distribution cabinet body 1, and the lower end of the base 4 is provided with matrix-distributed feet 41, the power distribution cabinet A cabinet door 15 is provided on the front wall of the cabinet body 1, and an anti-theft lock is provided on the cabinet door 15. It can be understood that after the cabinet door 15 is closed, the inner cavity of the power distribution cabinet body 1 is a closed space, effectively Waterproof and dustproof, a top cabinet 9 is installed on the upper end of the power distribution cabinet 1, and a backboard 2 is vertically installed at the rear of the inner cavity of the power distribution cabinet 1, and the backboard 2 separates the inner cavity of the power distribution cabinet 1 into The element cavity 101 on the front side and the cooling cavity 103 loca...

Embodiment 2

[0046] The difference between this embodiment and embodiment 1 is that, as Figure 3-5 As shown, the rear wall of the power distribution cabinet 1 is provided with a heat dissipation grid 8 for the cooling cavity 103 to communicate with the outside world, so as to ensure the contact between the outside air and the cooling pipes in the cooling cavity 103, thereby assisting in realizing rapid cooling. The effect is to protect the stable operation of the electrical components in the high and low voltage power distribution cabinet.

[0047] Refer to Example 1 for other undescribed structures.

Abstract

The invention relates to the technical field of high-and-low voltage switchgear and provides a closed high-and-low voltage power distribution cabinet suitable for multiple places. The invention aims to overcome the problem that heat generated by operation of electrical elements installed inside a traditional high-and-low voltage power distribution cabinet with a sealing function cannot be dissipated in time and thus easily causes aging of electrical elements in the cabinet body and burnout of the electrical elements due to high temperature in the cabinet body. The power distribution cabinet ofthe invention comprises a power distribution cabinet body and a base, wherein a top cabinet is mounted at the upper end of the power distribution cabinet body; a back plate is vertically installed onthe rear portion of an inner cavity of the power distribution cabinet body; the back plate divides the inner cavity of the power distribution cabinet body into an element cavity located on the frontside and a cooling cavity located on the rear side; a horizontal partition plate used for partitioning a liquid cavity out at the lower portion of the inner cavity of the element cavity is installed on the lower portion of the element cavity; and a cooling and heat dissipation system is arranged in the element cavity. The power distribution cabinet can be applied to multiple places, and has high social use value and application prospect.

Description

technical field [0001] The invention relates to the technical field of high and low voltage complete sets of equipment, in particular to a closed high and low voltage power distribution cabinet suitable for multiple places. Background technique [0002] High and low voltage power distribution cabinets, as the name implies, are power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then step down the low voltage through transformers. The side leads to the low-voltage power distribution cabinet, the low-voltage power distribution cabinet and then to each power distribution board, control box, switch box, through which some switches, circuit breakers, fuses, buttons, indicators, meters, wires and other protection devices A device that is assembled into a power distribution device that meets the design function requirements.
