Sealing waterproof mechanism used in power distribution cabinet

Abstract

The invention discloses a sealing waterproof mechanism used in a power distribution cabinet, and specifically relates to the field of power distribution cabinets. The sealing waterproof mechanism comprises a drainage base and a power distribution cabinet body; an electrostatic dehumidification box is arranged on the inner side of the power distribution cabinet body; the inner wall of the power distribution cabinet body and the inner side of an air inlet cooling mechanism are provided with a plurality of fixed support bars and equipment mounting racks; an electrostatic grid and a high-voltage electrostatic generator are arranged in the electrostatic dehumidification box; the top surface of the inner cavity of the power distribution cabinet body is provided with a temperature and humidity sensor; and one side of the electrostatic dehumidification box is provided with the air inlet cooling mechanism. According to the invention, the electrostatic grid in the electrostatic dehumidificationbox is used for filtering airflow entering the power distribution cabinet; liquid drop small particles and part of dust particles mixed in a large amount of inlet air flow can be effectively adsorbedthrough the electrostatic adsorption effect; the liquid drop small particles are gathered and liquefied in the electrostatic grid and then collected and discharged out of the outer side of the power distribution cabinet; and the dry environment in the power distribution cabinet is guaranteed on the basis that the sealing performance of the power distribution cabinet is not damaged.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, and more specifically, the invention is a sealing and waterproof mechanism for the interior of a power distribution cabinet. Background technique [0002] The power distribution cabinet is a commonly used power distribution equipment. It is often placed in the open air, so it is easy to enter the power distribution cabinet in rainy weather, which will affect the stability and safety of the communication cabinet. The existing technology mainly uses The sealing strip is sealed. Although it can complete the rainwater seal to a certain extent, it is easily aged in harsh environments for a long time, thereby affecting the waterproof performance of normal use, and the applicability and practicability are limited. In the case of flooding, water will enter the interior of the power distribution cabinet from the gap in the shell of the power distribution cabinet, and the components in ...

Problems solved by technology

[0002] The power distribution cabinet is a commonly used power distribution equipment. It is often placed in the open air, so it is easy to enter the power distribution cabinet in rainy weather, which will affect the stability and safety of the communication cabinet. The existing technology mainly uses The sealing strip is used for sealing. Although it can complete the rainwater seal to a certain extent, it is easy to age in the harsh environment after long-term use, thus affecting the waterproof performance of normal use, and the applicability and practicability are limited.

In the case of flooding, water will enter the interior of the power distribution cabinet from the gap in the shell of the power distribution cabinet, and the components in the power distribution cabinet will be soaked in water, which will cause the electrical equipment to fail to operate normally, and will also cause serious safety hazards

[0003] At present, the existing power distribution cabinets have been greatly improved in rainproof and waterproof performance. They can be closed and waterproof to maintain the stable operation of the internal equipment of the power distribution cabinet. The heat dissipation structure of the electric cabinet itself causes a large amount of moisture to enter the interior of the cabinet. Due to the influence of its sealed and waterproof structure, the moisture is difficult to discharge outside the equipment, resulting in a large amount of moisture accumulating into liquid droplets inside the power distribution cabinet, resulting in a short circuit of the equipment. High humidity environment is more likely to cause corrosion and aging of equipment
