Abstract

The utility model belongs to the technical field of transmission transformer, relating to a compact American transformer substation transformer structure specially used for American transformer substation, which comprises a high pressure gasoline tank and a transformer gasoline tank arranged side by side and separated by a clapboard, wherein the transformer gasoline tank is provided with a transformer, the high pressure gasoline tank is provided with a high pressure switch; the high pressure end three-phase conductor of the transformer is led and connected in the high pressure gasoline tank by three wall bushings on the clapboard, and a radiator is positioned on the upper of the high pressure gasoline tank and the transformer gasoline tank and is connected with the tank cap of the transformer gasoline tank. The utility model is of compact structure, small floor area, convenient mounting and transporting, little oil filling quantity and high operation reliability.

Description

Compact Type American Transformer Substation Transformer Structure

Technical field

The utility model belongs to the transmitting transformer technical field, relates to a kind of Compact Type American Transformer Substation Transformer Structure that is exclusively used in American transformer station.

Background technology

In the transformer device structure of existing American transformer station, radiator is generally gilled radiator or the ripple radiator that is arranged on the oil tank of transformer periphery, the device body of transformer and the same chamber of high tension apparatus, both sides at the fuel tank panel are provided with the high-low pressure case respectively, and this has just formed the American transformer station of traditional order font, isosceles triangle, L shaped structure.The defective that this structure exists is: 1, structure is not compact, and the space can not effectively utilize, make box-type substation after, floor space is big, volume is big, the inconvenience transportation; 2, its high tension apparatus generally is placed in the top of transformer body, and the fuel tank inner volume can not make full use of, and has increased the size of fuel tank, increases the use amount of transformer oil; 3, the contaminated oil of high-voltage switch gear hot line job generation can have influence on the operational reliability of transformer.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of compact conformation, it is little to take up an area of, installation and transportation convenient, innage is few, operational reliability high Compact Type American Transformer Substation Transformer Structure.

Compact Type American Transformer Substation Transformer Structure of the present utility model includes arrangement side by side and by pressure-oil tank and oil tank of transformer that dividing plate separates, transformer is installed in the oil tank of transformer, and high-voltage switch gear is installed in the pressure-oil tank; The high-pressure side three-phase conductor of transformer draws by three wall bushings on the dividing plate to be received in the pressure-oil tank, and radiator is positioned at the top of pressure-oil tank and oil tank of transformer and is connected with the case lid of oil tank of transformer.

The utility model is owing to will put on the radiator, make its compact conformation, take up an area of little, be convenient to transportation and install; Because the high tension apparatus part is independent separately with transformer portion, the fuel tank volume is used effectively, and innage obviously reduces, and has reduced cost; Oil in the pressure-oil tank and the oil in the oil tank of transformer are separated out, and the contaminated oil that the high-voltage switch gear hot line job produces can not have influence on transformer, thereby can improve its operational reliability.

Embodiment

As shown in the figure, in the transformer device structure of the American transformer station of the utility model, fuel tank is divided into separately independently pressure-oil tank 1 and oil tank of transformer 2 side by side, the three-phase conductor of step-up side draws by three wall bushings 3 on the dividing plate and receives in the pressure-oil tank in the oil tank of transformer, and the radiator 4 of transformer is positioned at whole fuel tank top and is fixedly connected on the case lid of oil tank of transformer.

Claims

1, a kind of Compact Type American Transformer Substation Transformer Structure is characterized in that: it includes arrangement side by side and by pressure-oil tank (1) and oil tank of transformer (2) that dividing plate separates, transformer is installed in the oil tank of transformer, and high-voltage switch gear is installed in the pressure-oil tank; The high-pressure side three-phase conductor of transformer draws by three wall bushings (3) on the dividing plate to be received in the pressure-oil tank, and radiator (4) is positioned at the top of pressure-oil tank and oil tank of transformer and is connected with the case lid of oil tank of transformer.
