Compact box-type substation

Abstract

The invention discloses a compact box-type substation, and belongs to the technical field of power supply devices. The compact box-type substation comprises a box top, a first side wall, a transformer, a high-voltage chamber, a low-voltage chamber, a heat dissipation device, heat dissipation window adjusting devices and a bottom wall; a second side wall is installed at one side of the first side wall, a third side wall is installed at the other side of the first side wall, and a fourth side wall is installed between the second side wall and the third side wall; heat dissipation openings are formed at one side of the second side wall and one side of the third side wall, the heat dissipation window adjusting devices are rotationally installed at the two sides of the heat dissipation openings, and each heat dissipation window adjusting device comprises baffles, a photoresistor, a micro motor and an angle sensor the baffles are rotationally installed at the two sides of the heat dissipation openings through the output ends of the micro motor, the photoresistor is fixedly installed at one side of the baffle, and the wiring end of the photoresistor penetrates through one side of the baffle and extends to an inner cavity of the baffle to be connected with the wiring end of the micro motor.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a compact box-type substation. Background technique [0002] The box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device, which replaces the traditional civil transformer. Compared with the traditional transformer, the box-type substation is small in size and easy to transport and install, so the box-type substation is widely used. Applied to various places. [0003] The heat dissipation equipment of the existing box-type substation mainly uses air cooling and water cooling to dissipate heat. Among them, the cost of water cooling is high and the space occupied is large, which will lead to an increase in the volume of the box-type substation compared with the previous ones, which is not conducive to the box-type substation. Substations are installed and transported, and box-type substations often ...

AI Technical Summary

Problems solved by technology

[0003] The heat dissipation equipment of the existing box-type substation mainly uses air cooling and water cooling to dissipate heat. Among them, the cost of water cooling is high and it takes up a lot of space, which will lead to an increase in the size of the box-type substation compared with the previous ones, which is not conducive to the box-type substation. Substations are installed and transported, and box-type substations often increase the installation height of box-type substations by increasing the foundation. Inside the electrical box, the equipment inside the box-type substation will be damaged due to long-term soaking in water, and the internal planning of the box-type substation is relatively complicated. Unreasonable use will lead to excessive occupation of each equipment and increase production costs
