Abstract

The utility model is an integrated box-type substation, at the rear of the box body of which a high temperature resistant liquid immersed transformer is arranged and the high pressure chamber and low pressure chamber is separated by a clapboard in the middle of the rectangular box. A Low pressure ceramic casing is positioned on the box wall between the rear of the low pressure chamber and the transformer, and a low voltage circuit breaker is positioned on the installation shelf of the central low-voltage circuit breaker. A capacitance room is provided at the right side of the low pressure chamber, and the clapboard is positioned between the two chambers, and capacitors and a capacitor monitoring device are positioned on the installation shelf inside the capacitance room. And a high voltage ceramic casing and high voltage switch installation beam are positioned on the box wall between the rear of the high voltage chamber and the transformer, high voltage load switches and a combined electrical appliance of the circuit breaker are positioned on the beam and the operation mechanism of high voltage switches are at the left of the combined electrical appliance. The high voltage switches of the utility model are oil-free, safely operate, and are maintained and operated more conveniently, with smaller size and less occupation land, overcoming the fundamental problem of phase-missing in operation in American box-type substations.

Description

Integrated Box Transformer Substation

Technical field

The utility model relates to the transformer station in equipment for power transmission and distribution field, especially a kind of Integrated Box Transformer Substation of miniaturization.

Background technology

Present American box-type substation, its volume is little, low price, the transformer good heat dissipation effect is taken up an area of and is lacked, convenient transportation, but its maintenance cost height, and can't solve the harm of phase-deficient operation to transformer itself and electrical network.Existing European box-type substation, its transformer capacity is bigger, and scheme combination is flexible, realized the no oiling design and the application of switch, but its volume is big, and result of ventilating heat dissipation is poor, and occupation of land is many, the cost height.

Summary of the invention

Technical problem to be solved in the utility model: be to supply a kind of Integrated Box Transformer Substation that has American box-type substation and European box-type substation advantage concurrently, utilize new technology, new material, reduced volume, reduce cost, convenient transportation, installation and use, improve power supply quality, strengthen fail safe and reliability.

For solving the technical scheme that above technical problem adopts is such: the utility model shell is a transformer station box, it is characterized in that: the casing rear is provided with high temperature resistant liquid-immersed transformer, in the middle of rectangular box, have with about high, the dividing plate that low-pressure chamber separates, tank wall between low-pressure chamber rear and the transformer is provided with the low pressure porcelain bushing, be provided with the installation column in relevant position, on the low-voltage circuit breaker installing rack of low-pressure chamber central authorities, be equipped with low-voltage circuit breaker, be provided with the electric capacity chamber in the low-pressure chamber right-hand member, and be provided with low-pressure chamber and electric capacity chamber dividing plate, the indoor capacitor mounting rail that the front and back trend is arranged of electric capacity, mounting rail is provided with capacitor and capacitor supervising device; On the tank wall between rear, hyperbaric chamber and the transformer, be provided with high voltage porcelain bushing pipe and high-voltage switch gear mounting rail, high voltage load switch and fuse combined electric apparatus being housed on mounting rail, being provided with the high-voltage switch gear operating mechanism at the combined electrical apparatus left end, is the high-voltage switch gear guidance panel in the operating mechanism left side.

Because adopt above technical scheme, its effect is conspicuous:

1, operation is safer, meets the development trend that national high-voltage switch gear does not have oiling, and when having avoided the on-load switch operation to the carbonization of transformer oil, effectively prolonged the useful life of transformer.

2, can expand high pressure measurement, and solve the root problem of phase-deficient operation.

3, operation and easy to maintenance, volume is littler, takes up an area of to lack, and economy is practical again.
