A high and low voltage prefabricated substation

Abstract

The invention discloses a high and low voltage prefabricated substation, which comprises a station building, a sealed door, a refrigeration device, an exhaust fan, and a heat dissipation pipe. There is a flow equalizer, the middle part of the upper end of the flow equalizer is provided with a heat dissipation pipe, both sides of the heat dissipation pipe are provided with bottom slide rails, the bottom slide rails are provided with an equipment mounting frame, and the equipment mounting frame is provided with Station room equipment, the front side of the station room equipment is a cold air area, and the rear side of the station room equipment is a hot air area. Both sides of the heat dissipation pipe are provided with upper partitions, and the upper end of the upper partition and the upper inner wall of the station building One end of the upper partition is docked with the airtight door. The refrigeration device is installed on one side of the station building. The refrigeration device communicates with the bottom of the station building through a cooling pipe, and the air outlet of the cooling pipe is located at the side of the cold air area. At the lower end, the exhaust fan is arranged on the outer wall of the station building, and the exhaust fan communicates with the hot air area.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a high and low voltage prefabricated substation. Background technique [0002] A substation is a power facility in the power system that transforms voltage, receives and distributes electric energy, controls the flow of power, and adjusts voltage. As an important power production site, a substation is mostly installed outdoors. Fault, ventilation and heat dissipation measures are essential, the existing substation only blows air from one side to the inside of the substation, blowing out the hot air, and the heat dissipation effect is not ideal. Contents of the invention [0003] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides a high and low voltage prefabricated substation. By changing the internal structure of the station building, the interior of the station building is divided into a cold air area and a hot air area,...

Problems solved by technology

[0003] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides a high and low voltage prefabricated substation. By changing the internal structure of the station building, the interior of the station building is divided into a cold air area and a hot air area, so as to realize the orderly flow of air flow. The lower end of the station building is equipped with a flow equalizer, which realizes the average distribution of cold air through the flow balance plate, and solves the problem of uneven heat dissipation in the current station building. Separate the station equipment inside the station to prevent the transfer of heat, and can play a very good heat dissipation effect, improve the heat dissipation effect of the station, and protect the normal operation of the internal equipment
