Abstract
The utility model relates to a tank-separating preassembled substation, which comprises a transformer, a high-voltage switch, a fuse, an operating chamber of a high-voltage switch and a chamber of a low voltage switch. The utility model is characterized in that the high-voltage switch, the fuse and the transformer are horizontally arranged in separate tanks, the high-voltage switch and the fuse are singly arranged in an oil tank of a high-voltage switch and a fuse, and the transformer is arranged in an oil tank of a transformer. Since the high voltage switch, the fuse and the transformer are separately arranged in two horizontal separate tanks by the utility model, the insulation performance of transformer oil is ensured and the service life of the transformer is extended. Since the tank of a transformer and an oil tank of a load switch and a fuse are respectively independent, the overhauling can be respectively conducted and the other tank does not need to be disassembled. After the tanks are horizontally separated, the oil tank of a transformer tank, the oil tank of a high-voltage switch and a fuse, the operating chamber of a high-voltage switch and the chamber of a low voltage switch can be arranged in parallel in different modes of left, right, front and back. The utility model has the advantages of convenient maintenance, small size, compact structure, beautiful appearance, good manufacturability of production and manufacture, simple processing and manufacture and man-hour saving.
Description
(1) technical field
The utility model relates to a kind of power transmission and transforming equipment, is a kind of case-distributed prepackage type transformer station specifically.
(2) background technology
In electric transmission and in using, for the high voltage electric energy in the electrical network is converted to low-voltage electric energy, extensively adopt preassembled transformer station, become as American case, because of its volume little, hermetically sealed, all insulation, supply power mode is flexible, advantage such as safe and reliable, be widely used in the town power distribution network, but its blemish in an otherwise perfect thing is a high voltage load switch, fuse and transformer place among the same fuel tank, the electric arc that produces when operational load switch or fuse action can make transformer oil produce carbonization, easily pollute transformer oil, reduce insulation level, reduce the performance and the useful life of transformer, even cause transformer to damage.
In order fundamentally to solve the above-mentioned deficiency of American transformer, some enterprises begin to produce the box case change of branch in recent years, the box case of producing as companies such as the high designed box case change of branch in west and Association of South-east Asian Nations, positive Thailands of branch becomes and is laminar branch mailbox up and down, the bottom is a transformer tank, top is on-load switch and fuse box, and there is following shortcoming in the box case change of this branch:
1, mounting means complexity during the product assembling, must be installed transformer tank earlier.After the transformer tank installation on-load switch and fuse box could be installed.
2, constant in maintenance, go wrong or transformer tank when the oil impregnate phenomenon occurring and overhauling as transformer, must take on-load switch and fuse box earlier apart after, could overhaul transformer tank is installed, so not only time-consuming but also effort, very trouble.
3, branch mailbox is owing to the effect of tank pressure difference up and down, if connector is poorly sealed between on-load switch and fuse and the transformer tank, when oil impregnate occurring, contaminated oil will enter transformer tank.
4, product structure complexity, overall dimension are big, are not easy to processing, and time-consuming, the manufacturing cost height, and manufacturability is poor, and is not attractive in appearance.
5, the low pressure equipped circuit is few, and scheme is simple.
6, between high and low voltage chamber continuously every, do not meet the electric operation rules.
(3) summary of the invention
In order to solve the deficiency that above-mentioned prior art exists, the utility model provides that a kind of volume is little, compact conformation, good looking appearance, branch box preassembled transformer station easy to maintenance.
The technical scheme that adopts is:
A kind of minute box preassembled transformer station, comprise transformer, high-voltage switch gear, fuse, high-voltage switch gear operating room, low tension switch chamber, its structural feature is the horizontal branch mailbox setting of described high-voltage switch gear and fuse and transformer, high-voltage switch gear and fuse are arranged on separately in high-voltage switch gear and the fuse fuel tank, transformer is arranged in the oil tank of transformer, between oil tank of transformer, high-voltage switch gear and fuse fuel tank, high-voltage switch gear operating room and low tension switch chamber four parts, can arrange side by side by the left-right and front-back different modes.
The utility model advantage is:
1, because high-voltage switch gear and fuse and transformer branch are located in two horizontal branch mailboxes, thereby the electric arc carbonization pollution transformer oil that produces can not make the action of on-load switch or fuse the time.Guarantee the insulation property of transformer oil, and then prolonged the useful life of transformer.
2, because transformer tank and on-load switch and fuse box are independent separately,, can overhaul respectively, need not tear another case open, the maintenance safe ready in case go wrong.
3, behind the horizontal branch mailbox, can arrange side by side by the left-right and front-back different modes between oil tank of transformer, high-voltage switch gear and fuse fuel tank, high-voltage switch gear operating room, low tension switch chamber four parts, volume is little, compact conformation, good looking appearance.
4, manufacturing process is good, and processing and manufacturing is simple, saves man-hour.

(5) embodiment
See also Fig. 1-Fig. 4, a kind of minute of the present utility model box preassembled transformer station comprises transformer 1, high-voltage switch gear 2, fuse 3, high-voltage switch gear operating room 4 and low tension switch chamber 5.Transformer 1 is arranged on and becomes in the device fuel tank 6.High-voltage switch gear 2 and fuse 3 be arranged on oil tank of transformer 6 high-voltage switch gear and fuse fuel tank 7 side by side in.High-voltage switch gear operating room 4 and low tension switch chamber 5 are arranged side by side the place ahead at oil tank of transformer 6 and high-voltage switch gear, fuse fuel tank 7.
Claims (2)
1, a kind of minute box preassembled transformer station, comprise transformer (1), high-voltage switch gear (2), fuse (3), high-voltage switch gear operating room (4), low tension switch chamber (5), it is characterized in that described high-voltage switch gear (2) and fuse (3) and the horizontal branch mailbox setting of transformer (1), high-voltage switch gear (2) and fuse (3) are arranged on separately in high-voltage switch gear and the fuse fuel tank (7), and transformer (1) is arranged in the oil tank of transformer (6).
