Heat dissipation structure and heat dissipation method for high-voltage switch cabinet

Abstract

The invention relates to the field of switch cabinets, in particular to a heat dissipation structure and a heat dissipation method for a high-voltage switch cabinet. The cabinet comprises a cabinet body, wherein an air inlet device is fixed at the upper end of the cabinet body; a primary filtering device is arranged in the air inlet device; an air outlet device is fixed at the lower end of the cabinet; a perforated plate is fixed in the cabinet body; a plurality of transverse brackets for mounting high-voltage switches are fixed at the front end of the perforated plate; a directional cooling device is arranged in the part, located at the front side of the perforated plate, of the cabinet body; the air inlet device communicates with the directional cooling device; the air outlet device communicates with the part, located at the rear side of the perforated plate, of the cabinet body; an auxiliary heat dissipation device is arranged on the part, located behind the perforated plate, of thecabinet body; and a dust removal device is arranged in an air inlet end part in the directional cooling device. According to the invention, the opening degree of an air outlet can be adjusted according to the high-voltage switches with different heating values, so sufficient air can flow through the high-voltage switches to perform specified heat dissipation on the high-voltage switches; dustproof effect is good; and the service life of the high-voltage switches can be prolonged.

Description

technical field [0001] The invention relates to the field of a switch cabinet, in particular to a heat dissipation structure and a heat dissipation method of a high-voltage switch cabinet. 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 And grounding switch, high-voltage load switch, high-voltage automatic recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear and other major categories. A serious problem in the existing switchgear is that the heat dissipation of the high-voltage switchgear is not fully considered. When the high-voltage switchgear cannot effectively dissipate heat, the internal temperature w...

Problems solved by technology

A serious problem in the existing switchgear is that the heat dissipation of the high-voltage switchgear is not fully considered. When the high-voltage switchgear cannot effectively dissipate heat, the internal temperature will rise, which not only greatly accelerates the internal parts of the high-voltage switchgear. Aging, and high temperature is easy to cause fire, there is a great safety hazard
