Description

Technical Field

[0001] The present invention relates to the technical field of buried transformers, and specifically to a lamp box buried transformer substation. Background Art

[0002] A buried transformer is a device used for voltage transformation. The basic principle of a buried transformer is to utilize the electromagnetic induction principle to achieve voltage transformation. It consists of parts such as a high-voltage coil, a low-voltage coil, an iron core, and a housing. When high voltage passes through the high-voltage coil, the magnetic flux inside the iron core changes, and when it passes through the low-voltage coil, the magnetic flux changes again, thereby achieving voltage reduction.

In winter, the heat in the geothermal well can be introduced into the sealed heat insulation box through a water pump to keep the transformer warm, which can prevent the viscosity of the transformer oil from increasing and the core loss from increasing due to low temperature. In summer, the heat in the sealed heat insulation box can be introduced into the geothermal well to cool the inside of the sealed heat insulation box, realizing "dual use of one well". 2. Since the transformer is directly installed inside the sealed heat insulation box and located underground, it can completely get rid of the dependence on the ground air for heat dissipation of the transformer. At the same time, a completely sealed waterproof design can be realized. And compared with traditional air cooling, heat dissipation through the geothermal well can improve the heat dissipation efficiency inside the sealed heat insulation box. Also, since the transformer is installed underground, the noise can be directly isolated underground, and at the same time, it has complete dust and waterproof functions. 3. Through borrowing the ground for heat dissipation, the underground rock and soil layer can be transformed into a natural radiator, perfectly avoiding the contradiction between ventilation and waterproofing in the traditional heat dissipation scheme, and relying on natural heat conduction, the energy efficiency ratio of the forced circulation mode is extremely high.

[0029] Guide blocks are fixedly connected to both the front and back of the moving block 503. Guide chutes for accommodating the sliding of the guide blocks are provided on the inner walls of the front and back of the fixed frame 405. The pushing frame 502 and the moving block 503 are both placed inside the fixed frame 405. The moving block 503 is slidably connected to the guide chutes on the fixed frame 405 through the guide blocks, and the pushing frame 502 and the moving block 503 can move within the fixed frame 405.

[0030] One end of the push rod 504 away from the heat dissipation connection arc plate 505 penetrates through the fixed frame 405 and extends into the fixed frame 405 to be fixedly connected to the moving block 503. The heat exchange tube rack 607 is attached between the heat dissipation connection arc plate 505 and the heat exchange plate 506. The heat absorbed by the heat dissipation connection arc plate 505 and the heat exchange plate 506 can be transferred through the flow of water in the heat exchange tube rack 607.

[0033] When the transformer inside the sealed heat-insulating box 1 generates heat during operation, the electric telescopic rod 402 is controlled to operate, so that the electric telescopic rod 402 controls the lowering of the lifting plate 403 and the lifting frame 404 during operation. When the lifting frame 404 moves downward, it squeezes the push plate 501, causing the push plate 501 to rotate. At the same time, the push plate 501 is stressed and pushes the pushing frame 502 and the moving block 503, so that the moving block 503 slides in the guiding chute on the fixed frame 405 through the guiding block. When the moving block 503 moves, the moving block 503 pushes the push rod 504 and the heat dissipation connecting arc plate 505 to move, so that the heat exchange plate 506 contacts the inner wall of the geothermal well, and can absorb the heat on the inner wall of the geothermal well onto the heat dissipation connecting arc plate 505 and the heat exchange plate 506. Then, the water pump 603 is controlled to operate, so that the water in the heat exchange water tank 601 is pumped out, and is introduced into the connecting pipe 604 through the liquid outlet pipe 602 and the water pump 603.
