Description

A kind of novel preassembled transformer station

Technical field

The utility model relates to power transmission and transforming equipment, promptly a kind of novel preassembled transformer station.

Background technology

The preassembled transformer station of the present extensive use of China is commonly called as case and becomes, and has European and American two kinds, and its characteristics and drawback are respectively arranged, and European case change all places box house with high and low pressure switchgear and transformer, separates with dividing plate, and volume is big, weak heat-dissipating.American case becomes because directly externally heat radiation of fin, season in spring and autumn radiating condition better, but in southern summer, sun direct projection, the temperature inside the box is very high; American in addition case uprises and compresses switch and transformer case altogether, and when the operate high pressure switch, the electric arc of generation causes the pasta temperature to raise easily with the transformer oil carbonization, and easily oxidation influences the insulation property of transformer oil.

Summary of the invention

In order to overcome big, the weak heat-dissipating of European case variable volume, American case becomes weak heat-dissipating, unsafe shortcoming, the utility model proposes that a kind of comprehensive European case becomes and American case change advantage, good heat dissipation, safer, new design that volume is little.

This novel preassembled transformer station, by the hyperbaric chamber in casing and the casing, low-pressure chamber and transformer room form, be equipped with high-voltage switch gear in the hyperbaric chamber, be equipped with low tension switch in the low-pressure chamber, be equipped with transformer in the transformer room, it is characterized in that, casing is a cuboid, low-pressure chamber is in a side on long limit, and hyperbaric chamber and transformer room are at the opposite side on long limit, and above-mentioned three chambers are cuboid, separate with dividing plate, on horizontal profile, three chambers are isosceles triangle arranges have connecting line to link to each other between three Room, on the boxboard of the tank ends of hyperbaric chamber and low-pressure chamber, the heat radiation window is arranged, on the boxboard of transformer room's casing and door, the heat radiation window is arranged also, at low-pressure chamber, on hyperbaric chamber and the transformer room box plate outwardly, respectively be provided with 1～2 door.

In low-pressure chamber, top is the metering basement, and the bottom is capacitor chamber and outlet chamber.

Transformer is general oil-filled transformer or dry-type transformer.

High-voltage switch gear is the sulphur hexafluoride on-load switch.

The configurable Electric capacity compensation device of low-pressure chamber.

The utility model has the advantages that: 1, volume is little, in light weight, and performance of ventilating is good, can eliminate because condensation causes the danger of insulation fault; 2, dustproof, moistureproof, anti-toy is safe and reliable, easy to maintenance; 3, high-voltage switch gear adopts the sulphur hexafluoride on-load switch, can realize looped network, double loop or terminal power supply; 4, low-pressure side disposes Electric capacity compensation device, can realize high voltage supply high pressure measurement or high voltage supply low-temperature measurement, also can adopt the multiloop outlet.
