Gas-heat inclined drainage type condensation-removing switch cabinet

Abstract

The invention discloses a gas-heat inclined drainage type condensation-removing switch cabinet, belonging to the field of switch cabinets. Through the cooperative arrangement of a water-heating balloon and a self-inclined condensation-guiding plate, when a condensation phenomenon occurs, a part of liquefied water drops are concentrated at the self-inclined condensation-guiding plate, a part of the water drops go upwards and are absorbed by a water absorption ball, a part of water drops enter the water-heating balloon under the absorption action of water guiding beards, so the water-heating balloon absorbs water and generates heat to expand, and expansion force directly extrudes the self-inclined condensation-guiding plate to allow the self-inclined condensation-guiding to be in an inclined state; a part of water drops which are not absorbed slide down to the inner wall of the cabinet door along an inclined plane, so compared with the prior art, the top is effectively prevented from direct and vertical dripping of condensation, and the damage rate of electrical elements is reduced; and in addition, due to the fact that the water-heating balloon is heated, the temperature difference between the self-inclined condensation-guiding plate and hot air in the cabinet body is reduced, the occurrence rate of the condensation phenomenon on the top of the cabinet body is effectively reduced, and the electrical elements are further protected.

Description

technical field [0001] The invention relates to the field of switch cabinets, more specifically, to an air-heat inclined drainage type decondensation switch cabinet. Background technique [0002] The main function of switchgear is to switch, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many classification methods of switch cabinets. For example, according to the installation method of circuit breakers, it can be divided into removable switch cabinets and fixed switch cabinets; or according to the different cabinet structures, it can be divided into open switch cabinets, metal-enclosed switch cabinets, and metal Closed armored switchgear; according to different voltage levels, it can be div...

AI Technical Summary

Problems solved by technology

[0003] There are usually multiple electrical components installed in the switchgear, which will generate a lot of heat during operation. In winter, especially in areas with high air humidity, after being heated, the hot and humid air in the switchgear encounters the inner wall of the switchgear with a lower temperature. Due to the temperature difference, condensation will occur on the inner wall. When the condensation is severe, the condensed dew will drip on the electrical components in the switch cabinet, causing damage to the electrical components, resulting in a high damage rate, especially on the top of the switch cabinet. , when condensation occurs at this place, the condensed water drops will fall vertically and will fall directly on the electrical components. Compared with the condensation on the side wall, the condensation at this place will do more damage to the electrical components
