Description

Used for wind power generation combined transformer waterborne

Technical field

The utility model relates to a kind of combined transformer, relates in particular to a kind of box-like transformer of wind power generation dedicated set that is adapted at using on the water surface.

Background technology

Wind power generation more and more receives the attention of countries in the world as a kind of clean reproducible energy.And combined transformer is owing to its convenience with short production cycle, simple in structure, an advantage such as less investment have obtained extensive use.This novel used for wind power generation combined transformer waterborne is specially for the mode of connection on the water surface designs, and voltage is boosted to the electric equipment that is connected to the grid behind the 35Kv (10kV) by 0.69kV.

There is following shortcoming in existing used for wind power generation combined transformer on using:

1, receive the region restriction bigger.Wind power generation is followed the wind resource abundant area and is established; The power generation site complicated topographical conditions is changeable; Be arranged on areas such as seabeach, shoal, lake surface sometimes; And also do not have on the market separately for to be located at the combined transformer that manufactures and designs in the water, common combined transformer often receives condition restriction such as antiseptic power, ground size bigger;

2, the high-pressure side mode of connection is single.Existing combined transformer can only realize the built on stilts inlet wire in subjacent cable inlet wire or top one of them, can not satisfy combined transformer waterborne and both can realize cable outlet, various demand that again can overhead outlet;

3, the combined transformer of overhead outlet can not install high-voltage arrester (or overvoltage protection device) additional.Common built on stilts inlet wire type combined transformer all adopts the outlet of bushing top, and transformer one side is a low-pressure chamber, and a side is a gilled radiator, because limited space should not install overvoltage protection again additional.

Summary of the invention

For solving the problems referred to above that existing combined transformer exists, the utility model provides a kind of high and low pressure components and parts to adopt the used for wind power generation combined transformer waterborne of new arrangement mode, and its technical scheme of taking is:

The low-pressure chamber of right side of face before this combined transformer comprises oil tank of transformer, is positioned at the operation with high pressure chamber of oil tank of transformer front, left side and is positioned at oil tank of transformer; The left and right sides of oil tank of transformer is respectively equipped with gilled radiator; The back of oil tank of transformer is provided with high-voltage terminal sleeve pipe and lightning arrester; Be provided with transformer body in the oil tank of transformer; Be provided with low-tension bushing and low-voltage cabinet in the low-pressure chamber, low-voltage cabinet links to each other with transformer body through low-tension bushing, and transformer body links to each other with outside overhead wire or bottom outlet cable through the high-voltage terminal sleeve pipe simultaneously.

Said high-voltage terminal sleeve pipe is porcelain bushing and the horizontal mounting means of employing, and said lightning arrester can replace with overvoltage protection device.

This combined transformer designs for wind power generation waterborne specially, adopts the mode of high voltage porcelain bushing pipe side outlet, owing to use on the water, has reduced the workload of building ground; The top overhead outlet both can be realized in the high-pressure side, also can realize the subjacent cable outlet, can use the subjacent cable outlet in the phytal zone, and the profundal zone also can overhead outlet; Gilled radiator is arranged on the left and right sides of fuel tank, and the overvoltage situation that case becomes can protected and monitor to dress lightning arrester sum counter below bushing.

Therefore the utlity model has compactness rational in infrastructure, production cost is low, and performance is safe and reliable, good looking appearance, the characteristics of convenient maintenance.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

Like Fig. 1, Fig. 2 and shown in Figure 3; Oil tank of transformer 14 is placed in the middle; Operation with high pressure chamber 3 and low-pressure chamber 5 lay respectively at the left and right sides of oil tank of transformer 14 fronts, and making the back of oil tank of transformer 14 is the high-pressure side, and the lightning arrester that horizontal arrangement is set 12 (or overvoltage protection device) of adequate space is arranged; The upper and lower of lightning arrester 12 is established connected high-voltage terminal sleeve pipe 11 sum counters 13 respectively, and wherein high-voltage terminal sleeve pipe 11 is porcelain bushing and adopts horizontal mounting means.Gilled radiator 9 is arranged on the left and right sides of oil tank of transformer 14, and is both elegant in appearance, can bring into play the natural cooling effect of air again to greatest extent.Low-pressure chamber 5 comprises low-voltage cabinet 10 and low-tension bushing 1; Low tension switch in the low-voltage cabinet 10 links to each other with subjacent cable; The operation of instrument and meters such as high-tension fuse 8, shunting switch 4 and on-load switch 6 all is arranged in the operation with high pressure chamber 3 isolated, that do not have electrified body, and handling safety is reliable.Low-voltage cabinet 10 links to each other with transformer body 2 through low-tension bushing 1, and transformer body 2 links to each other with outside overhead wire or bottom outlet cable through high-voltage terminal sleeve pipe 11 simultaneously.

When using this combined transformer; Remain with air gap more than the pasta of oil tank of transformer 14; Be used for compensator transformer oil because the space that gradient of temperature forms; Electric energy gets into from low-voltage cabinet 10, is upgraded to high side voltage through transformer body 2, gets into 110kV or 220kV booster stations again after being in communication with the outside through high voltage porcelain bushing pipe 11 then.
