A new type of cooling device for box-type substation with self-contained power supply

Abstract

The invention relates to the technical field of self-contained power supply heat dissipation, and discloses a novel box-type substation heat dissipation device with self-contained power supply, including a cabinet, rubber bases are fixedly connected to the four corners of the bottom of the cabinet, and solar photovoltaic panels are fixedly connected to the top of the cabinet ; The rear side of the inner cavity of the cabinet is vertically upwardly fixedly connected with a heat-dissipating aluminum box. In the present invention, the two connecting pipes on the rear side of the heat-dissipating aluminum box are sealed and inserted into the butt joint holes of the heat-dissipating aluminum box, and the suction pump works in the later stage to suck the oil in the oil tank into the heat-dissipating aluminum box and discharge it. Through the docking hole into the back-type heat dissipation aluminum box, the heat of the transformer is fully cooled and dissipated in an all-round way, and the heat dissipation efficiency is higher; when there is a lot of heat in the heat dissipation aluminum box, it is exhausted through the one-way valve and the air release valve to avoid internal heat dissipation. The heat cannot be dissipated; at the same time, the four sets of exhaust fans work to fully exhaust the heat on the cooling fins to ensure the cooling effect.

Description

technical field [0001] The invention relates to the technical field of self-contained power supply heat dissipation, in particular to a novel box-type substation heat dissipation device with self-contained power supply. Background technique [0002] At present, the medium and low voltage cabinets of existing box-type substations are generally located on opposite sides of the transformer, and the transformer can only be equipped with heat dissipation devices on the other two sides, that is, double-sided heat dissipation. In addition, there is no other auxiliary heat dissipation structure. In hot and humid areas, especially in the Yangtze River Basin, the temperature is high and the humidity is high in summer. If the cooling device of the substation with this structure is used, the temperature of the equipment in the substation will be high. The service life of the transformer. [0003] The heat dissipation mechanism provided in this technical solution is only equipped with a...

Problems solved by technology

In hot and humid areas, especially in the Yangtze River Basin, the temperature is high and the humidity is high in summer. If the cooling device of the substation with this structure is used, the temperature of the equipment in the substation will be high. Transformer service life

[0003] The heat dissipation mechanism provided in this technical solution is only equipped with a heat conduction plate for heat transfer and heat dissipation, but it can only dissipate the heat on the rear side wall of the transformer, and the heat dissipation effect is poor; The heat formed cannot be discharged in time, which affects the final heat dissipation effect
