Abstract

The utility model relates to a pre-installed basement power substation, comprising a transformer house, wherein, the structure of which can be disassembled and assembled, the top of which is provided with an air exhausting duct, and one side of which is provided with an air inlet duct, a high voltage ring net cabinet, a low voltage power distributing cabinet, a capacitor disk, an operating platform and associated circuits. The utility model has the advantages of low noise, small volume, quick heat radiation, top wires, convenient disassembly and assembly, convenient transportation, etc. The utility model is suitable for being installed and used by 10KV basement power substations with small area and bay, such as a resident building, an office building, a business building, an enterprise building, etc.

Description

The basement preassembled transformer station

The utility model belongs to the power system transformer substation device, relates to a kind of basement preassembled transformer station that is applicable to small sizes such as residential building, the little standard width of a room in an old-style house.

Traditional transformer station is made up of unit such as transformer room, hyperbaric chamber, low-pressure chambers, because each unit is not removable integral body, volume is big, be not easy to carrying, must use crane lifting, again because floor space is bigger, the space that generally is used for outdoor or one-storey house can not be used for basement.Existing transformer station generally adopts inlet wire mode under the cable, must dig out cable trough in advance when civil engineering, can not be applicable to the basement transformer station of small sizes such as residential building, the little standard width of a room in an old-style house.Its ventilation and heat of existing transforming plant apparatus adopts ventilation fan usually, when fan damages influence and ventilates, must interruption maintenance, and also existing transforming plant apparatus do not have its anti-noise facility more, can not install in the residential building basement.

The purpose of this utility model is to provide a kind of super low noise that has, and little, the rapid heat dissipation of volume is dismantled and assembled, the basement preassembled transformer station of being convenient to carry.

The purpose of this utility model is achieved in that a kind of basement preassembled transformer station, comprise transformer room, high pressure ring cabinet, low-voltage distribution cabinet, capacitance disk, operating platform and interlock circuit, it is characterized in that the transformer room is dismantled and assembled structure, the top is that exhausting duct, a side are air inlet duct.The biside plate of transformer room and two panels adopt mother-son mouth to connect, and side plate is provided with Fire Hose.Be provided with muffler plate in exhausting duct and the air inlet duct.The side plate and the panel of transformer room are double panel structure, and inner plating has sound attenuation hole.

The utility model combines transformer and high and low pressure equipment by removable shell, adopt sound insulation double panel structure and noise elimination air channel to solve transformer heat radiation and noiseproof problem, solved the problem of the necessary trench excavation of time inlet wire, compared with prior art, have following good effect:

1. the frame shell is dismantled and assembled structure, and carrying is convenient in the cordwood system type combination, and general door can pass in and out.

2. super low noise can be installed under residential building, and the structure miniaturization can be at 24-40m ²Install in the basement.

3. the high and low pressure cable all can be passed in and out by the top, need not civil engineering.

4. there is not combustible, the fire protecting performance height.

5. natural draft heat radiation reduces maintenance.

6. rationally distributed, compact conformation, volume is little, is suitable for small size, the little standard width of a room in an old-style house, basement 10KV transformer stations such as residential building, office building, commercial building, enterprise building and installs and uses.
