Description

Technical Field

[0001] This utility model relates to the field of prefabricated transformer substation technology, specifically a pre-installed underground prefabricated transformer substation. Background Technology

[0002] A prefabricated substation mainly consists of a transformer unit and a power distribution unit. Conventional prefabricated substations house the transformer, high-voltage and low-voltage switchgear, and all are placed on the ground inside the enclosure. After more than ten years of development, prefabricated substations have become more rational in structure, compact in layout, simple to install, convenient to use and maintain, and have diverse appearances that are in harmony with the surrounding environment. Their products are distributed throughout the country.

[0003] Transformers generate harmful radiation and noise pollution when they are working, and they also occupy surface area. Therefore, some manufacturers bury the transformer unit and the power distribution unit underground. To ensure the heat dissipation effect of the equipment inside the transformer, fans are usually installed to ventilate and dissipate heat inside the transformer. However, when the humidity in the air is high, the ventilation and heat dissipation inside the transformer can easily cause water vapor to be generated inside the transformer, which in turn affects the equipment inside the transformer.

[0026] Please see Figure 2-5 This utility model provides a pre-installed underground transformer substation technical solution: A pre-installed underground transformer substation, the dehumidification and ventilation air intake device 55 includes an air intake fan 551, an air intake pipe 552, a dehumidification box 553, a water collection plate 554, an air inlet 555, a bracket 556, a drain pipe 557, a filter plate 558, and absorbent cotton 559. The top of the air intake fan 551 is connected to one end of the air intake pipe 552, and the other end of the air intake pipe 552 is connected to the top of the dehumidification box 553. The water collection plate 554 is installed in the middle of the dehumidification box 553. An air inlet 555 is provided at the bottom left side of the dehumidification box 553. The bracket 556 is fixed at the bottom corner of the dehumidification box 553. The drain pipe 557 is connected to the middle of the bottom of the dehumidification box 553.

The air intake fan 551 is fixed to the bottom of the box 51 and the bottom of the air intake fan 551 is connected to the pre-installed transformer body 1. The bottom of the bracket 556 is fixedly connected to the box 51. The left end of the drain pipe 557 extends through the left side wall of the box 51, so that the water inside the dehumidification box 553 is discharged to the outside of the box 51 through the drain pipe 557. The bottom wall of the dehumidification box 553 is inclined from the outside to the inside towards the connection of the drain pipe 557, so that the water inside the dehumidification box 553 can enter the drain pipe 557 for discharge. Three sets of water collection plates 554 are provided to increase the dehumidification effect of moisture in the air.

[0027] When in use, first install the prefabricated transformer in the required position. The temperature and humidity inside the prefabricated transformer body 1 are monitored in real time by the temperature and humidity sensor inside the prefabricated transformer body 1. When the temperature or humidity inside the prefabricated transformer body 1 reaches the preset rated value, ventilation and heat dissipation are required inside the prefabricated transformer body 1 to avoid the temperature or humidity inside the prefabricated transformer body 1 being too high and affecting the equipment inside the prefabricated transformer body 1.

Then, it enters the prefabricated transformer substation body 1 through the air inlet pipe 552. The exhaust fan 57 draws in the hot or humid air inside the prefabricated transformer substation body 1 and discharges it through the air outlet pipe 58, thereby achieving the effect of ventilation, heat dissipation and dehumidification inside the prefabricated transformer substation body 1.

[0029] The water absorbed by the water collection plate 554 drips into the bottom of the dehumidification box 553 and is then discharged through the drain pipe 557.
