Abstract

The utility model discloses an underground substation comprising a waterproof concrete prefabricated box buried in the ground pit and a ground pit cover plate which seals and matches with the ground pit. The middle of the box is provided with a door and at the lower part of the box is provided with a diaphragm in which has an air opening to separate the high-low voltage chest and transformer into a high-low voltage distribution room and a transformer room. The side wall of the box in the high-low distribution room is provided with an air-inlet which has an interconnecting high-low voltage distribution room and a grounding right-angle air inlet pipe. The side wall of the transformer room is provided with an air-outlet which has a channel continuous transformer and a grounding right-angle air outlet pipe. The utility model has the following advantages: 1) the utility model can be applied to the places which have the strict requirement for the ground landscape as all the power distribution facilities are arranged under the ground. 2) the excellent ventilation guarantees the control of the temperature rise of the equipment so that the equipment can be safely operated. 3) With no need of the corresponding drainage system, the ground pit is completely sealed to guarantee no water flowing to the ground pit which will cause the accident such as short-circuits.

voltage cabinet

1,2 separate into high and low voltage electric distribution chamber 51 and transformer room 52 with transformer 3, on the 51 melt pit cover plates 6 of living in of high and low voltage electric distribution chamber, be provided with the import and export 60 that enter for the maintainer, its inlet and

outlet

61,62 are located at respectively on the melt pit cover plate 6 upper and lower tank walls at protrusion position in the outside of the outside of high and low voltage electric distribution chamber 51 and transformer 52 and with iron bar and seal, as rainy day, rainwater can flow in the melt pit and by supporting gutter along the iron bar that protrudes the position and discharge, under the perfect not enough situation of drainage system, a large amount of ponding enters 4 li of melt pits as can't discharge smoothly, enter the most at last in the high and low voltage electric distribution chamber 51, its result will cause major accidents such as short circuit.

Summary of the invention

So the utility model purpose is overcoming the deficiencies in the prior art, a kind of underground type transformer station is provided, this underground type transformer station guarantees on ground no distribution facility and need not supporting drainage system.

The technical scheme that realizes above-mentioned purpose is: a kind of underground type transformer station, comprise waterproof concrete prefabricated box of imbedding in the melt pit and the melt pit cover plate that is sealed and matched with this melt pit, the centre of casing is provided with door by one, and the dividing plate that is provided with ventilation opening in the bottom is with height, low-voltage cabinet separates into high and low voltage electric distribution chamber and transformer room with transformer, offer air intake on the wall box of described high and low voltage electric distribution chamber, set out the air port on the wall box of transformer room, described air intake is provided with the rectangular-shaped intake stack that is communicated with high and low voltage electric distribution chamber and ground, and described air outlet is provided with the rectangular-shaped wind pipe on Dao Lian transformer room and ground.

Above-mentioned underground type transformer station wherein, describedly can settle ventilation fan respectively on the air port.

Above-mentioned underground type transformer station wherein, also is provided with Temperature Detector on the described ventilation fan.

Above-mentioned underground type transformer station wherein, is provided with the access hole of coming in and going out for the maintainer hermetically on the melt pit cover plate that is positioned at described high and low voltage electric distribution chamber.

Above-mentioned underground type transformer station, wherein, described air intake and air outlet can be located on the corresponding melt pit cover plate in low-voltage distribution chamber and transformer room.

The utility model has the advantages that: 1) adapt to the place that ground landscape is had strict demand, all distribution facilities are installed in underground; 2) well-ventilated guarantees that the equipment temperature rise is controlled so that equipment safety operation; 3),, the assurance melt pit causes accidents such as short circuit thereby can not intaking because the sealing fully of melt pit need not corresponding drainage system.
