Ventilation and heat dissipation structure of high voltage switch cabinets

Abstract

The invention relates to the technical field of high voltage switch cabinets, and discloses a ventilation and heat dissipation structure of high voltage switch cabinets. The structure includes a switch cabinet body, a left rubber pad, a right rubber pad, an air-leading bucket and an exhaust fan; the left rubber pad is located in the middle position on the left side of the inner wall of the switchcabinet body; and the right rubber pad is located in the middle position on the right side of the inner wall of the switch cabinet body. Through the arrangement of left and right slotting on the leftand right sides of the inner walls of the switch cabinet body, effects of natural ventilation of the switch cabinet body can be realized; through the installation of a first and second blower on the left and right sides of the inner walls of the switch cabinet body, fresh air can be absorbed from outside to discharge to the inner cavity of the switch cabinet body; through the inclined arrangementof a wind-guiding plate I and a wind-guiding plate II, the direction of horizontal blowing can be changed, no dead angle blowing of the inner cavity of the switch cabinet body can be realized, and compared with traditional ventilation and heat dissipation structures of high voltage switch cabinets, the structure is better in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of high-voltage switch cabinets, in particular to a ventilation and heat dissipation structure for high-voltage switch cabinets. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as electrical products with a voltage level of 3.6kV ~ 550kV, and high-voltage isolating switches There are several categories such as grounding switch, high-voltage load switch, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear. The switchgear has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly applicable to various places such as power plants, substations, pe...

Problems solved by technology

[0003] The existing high-voltage switchgear used outdoors has been placed outdoors for a long time. Due to the influence of the environment, dust often enters and accumulates. If the dust accumulates seriously, it enters the inner cavity of the high-voltage switchgear and will affect circuit components. Moreover, the existing high-voltage switchgear works for a long time without an independent ventilation and heat dissipation structure, which leads to the inability to dissipate the heat of the high-voltage switchgear, thereby affecting the power of its lines
