Abstract

The utility model discloses a special transformer for photovoltaic power generation, which comprises a transformer oil tank, a transformer body, a high-voltage sleeve, two groups of low-voltage sleeves and an oil storage cabinet. The transformer body is located in the transformer oil tank, the high-voltage sleeve and the low-voltage sleeves are located at the top of the transformer oil tank, the oil storage cabinet is located above the transformer oil tank and communicated with the same, the transformer body is an axial double-splitting structure, the transformer oil tank is a finned radiator structure, and the two groups of low-voltage sleeves are led out independently. The special transformer has the advantages of simple and applicable structure, safe and reliable property and convenient maintenance.

Description

The photovoltaic generation dedicated transformer

Technical field

The utility model relates to a kind of transformer that uses in photovoltaic generation.

Background technology

China's photovoltaic industry fast development, solar cell yield surpassed 4,000,000 kilowatts in 2009, accounted for 40% of world's photovoltaic cell output.Photovoltaic generation compares with thermal power generation that equipment is concise, reliable, the life-span is long, convenient for installation and maintenance, non-pollution discharge thing, construction period are short, also can utilize advantage such as building roof, therefore adopts photovoltaic generator to carry out photovoltaic generation and to develop its special-purpose transformer imperative.

For the photovoltaic generator transformer, require its anti-short circuit capability strong, also require the also generator more than two, adopt existing transformer can not satisfy above-mentioned requirements.

Summary of the invention

For realizing the above-mentioned requirements of photovoltaic generator to transformer, the utility model provides a kind of photovoltaic generation dedicated transformer, and its technical scheme of taking is:

The oil conservator that this transformer comprises oil tank of transformer, is positioned at the transformer body of oil tank of transformer, the bushing that is positioned at the transformer oil box top and low-tension bushing and is positioned at the oil tank of transformer top and is communicated with it, the transformer body is axially two splitted construction, oil tank of transformer is a sheet dissipating bind structure, and low-tension bushing is two groups and independently draws.

The transformer body adopts axially two splitted construction, and generator can be separately and branch's parallel running of this transformer, also can be with two branch's parallel runnings of two generators and this transformer.This overhauls, adjusts generating set according to power load and provide convenience for generating set.

Therefore the utlity model has simple and practically, performance is safe and reliable, the characteristics that maintenance cost is low.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the left view of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As Fig. 1, Fig. 2 and shown in Figure 3, transformer body 5 is positioned at oil tank of transformer 1, bushing 3 and two groups of low-tension bushings of independently drawing 4 are installed in the top of oil tank of transformer 1, oil conservator 2 is positioned at the top of oil tank of transformer 1 and is communicated with oil tank of transformer 1, transformer body 5 is axially two splitted construction, oil tank of transformer 1 is a sheet dissipating bind structure, and sheet diffusing 6 is located at the front side and the rear side of oil tank of transformer 1 respectively.

This transformer low voltage up and down two branch roads does not have the contact of electricity, but the contact of magnetic is arranged, and this transformer can move with a low pressure branch by high pressure, also can high pressure and two low pressure branches move simultaneously, if two low pressure capacity, voltage is identical, can also be with two branch's parallel runnings.When the generating set of two parallel runnings has a needs maintenance, it can be withdrawed from, have only a unit operation, when power load is low, also satisfyingly withdraw from a unit, this provides convenience for the client, has saved cost.

Claims

1. photovoltaic generation dedicated transformer, the oil conservator (2) that comprises oil tank of transformer (1), is positioned at the transformer body (5) of oil tank of transformer (1), the bushing (3) that is positioned at oil tank of transformer (1) top and low-tension bushing (4) and is positioned at oil tank of transformer (1) top and is communicated with it, it is characterized in that: transformer body (5) is axially two splitted construction, oil tank of transformer (1) is a sheet dissipating bind structure, and low-tension bushing (4) is two groups and independently draws.
