Double-circulation ventilation cabinet of auxiliary transformer for locomotive

Abstract

The invention discloses a double-circulation ventilation cabinet of an auxiliary transformer for a locomotive. The double-circulation ventilation cabinet comprises a cabinet body, a cabinet top fan and the transformer, and further comprises a clapboard structure, a cyclone dust remover, a dust removal box, a dust exhaust air duct and a heat dissipation fan of the auxiliary transformer, wherein the clapboard structure comprises an inclined plate, a horizontal plate and a vertical plate; one end of the inclined plate is connected with the interior of the cabinet body, and the other end of the inclined plate is connected with one end of the horizontal plate; the angle formed by the inclined plate and the horizontal plate is 130-160 degrees; the other end of the horizontal plate is connected with the dust removal box; one end of the vertical plate is connected with the inclined plate, and the other end of the vertical plate clings to the transformer; the cyclone dust remover and the heat dissipation fan of the auxiliary transformer are arranged at the inner side of the cabinet body; the cyclone dust remover and the dust removal box are both communicated with the dust exhaust air duct. The double-circulation ventilation cabinet disclosed by the invention greatly improves the working environment of the auxiliary transformer, and thoroughly solves the grounding faults of the auxiliary transformer, due to water inlet and dust inlet.

Description

technical field [0001] The invention relates to the field of heat dissipation in a mechanical room of an electric locomotive, in particular to an auxiliary transformer double-circulation fume hood for an electric locomotive. Background technique [0002] At present, there are two ventilation methods for the auxiliary transformer cabinet of electric locomotives at home and abroad: 1. The auxiliary transformer cabinet only provides ventilation and heat dissipation for the auxiliary transformer, and does not have the ventilation and heat dissipation function of the mechanical room. 2. The auxiliary transformer cabinet not only provides ventilation and heat dissipation for the auxiliary transformer, but also has the function of ventilation and heat dissipation in the mechanical room. [0003] Both types of auxiliary transformer cabinets have only one ventilation branch and are equipped with a cooling fan. The auxiliary transformer cabinet is suitable for the ventilation and hea...

Problems solved by technology

[0004] The auxiliary transformer cabinet of an electric locomotive that enters the wind from outside the vehicle, after the air outside the vehicle is roughly filtered, some rainwater and dust still enter the cabinet. The auxiliary transformer works in the environment of rainwater and dust for a long time, which accelerates the aging of the insulation and reduces the insulation performance. ground fault in the auxiliary transformer
