Problems solved by technology

[0003] At present, the following problems exist in the protection and use of outdoor high and low voltage power distribution cabinets: a. Most of the existing protection devices for power distribution cabinets use sealed protection or mesh protection, and the sealed protection can effectively isolate the outside rainwater, flying sand and stones and Litter and fallen leaves fall into it, but the air permeability is poor and there is no heat dissipation capacity; the mesh protection can effectively dissipate heat, but it is not rainproof, and sand, stones and fallen leaves will also fall into it through the protection device; b. Existing protection Generally, the device can only be opened on one side so that the staff can enter it to inspect and maintain the power distribution cabinet, but it is inconvenient when it is necessary to inspect and maintain other positions of the power distribution cabinet

Abstract

The invention relates to the technical field of power distribution cabinets, in particular to a high-low voltage power distribution cabinet protection device which comprises a side wall protection mechanism and a top cover mechanism, the side wall protection mechanism is installed on an existing foundation, a power distribution cabinet is arranged in the side wall protection mechanism, and the top cover mechanism is arranged at the top of the side wall protection mechanism. The protection device designed by the invention can realize the functions of preventing rain and sand, stone and fallen leaves, the periphery of the power distribution cabinet is mainly separated and protected through the protection door, and downward inclined vent holes formed in the protection door can realize gas exchange between the outside and the interior of the protection device, so that the power distribution cabinet can be cooled, and the service life of the power distribution cabinet is prolonged. Meanwhile, the downwards inclined vent holes can prevent rainwater from entering the protection device, and the rainproof function is achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a protective device for high and low voltage power distribution cabinets. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is the general name of the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits. The motor control center is used in the occasions where the load is concentrated and there are many circuits. The electrical energy distributed to the nearest load, this level of equipment should provide protection, monitoring and control of the load. [0003] At present, the following problems exist in the protection and use of outdoor high and low voltage power distribu...
