Abstract
The utility model discloses a combined type transformer for photovoltaic generation. The combined type transformer comprises a transformer chamber, a high voltage cable chamber, a low voltage chamber and a high voltage operation chamber, wherein the fours chambers are tightly arranged in a shape like a Chinese character pin. The transformer chamber is equipped with a transformer body and a fuse oil tank. The high voltage cable chamber is equipped with a lightning arrester, a high voltage sleeve and an insulator. The low voltage chamber is provided with a low voltage sleeve and a low voltage cabinet. The high voltage operation chamber is provided with a tapping-off switch and a load switch. The right end of the high voltage sleeve is arranged inside the fuse oil tank. The tapping-off switch is disposed above the transformer body. The load switch is disposed below the fuse oil tank. A low voltage top cover is connected with a high voltage top cover via a U-shaped plate. The combined type transformer for photovoltaic generation is reasonable and compact in structure, low in production cost, safe and reliable in performance and convenient in maintenance.
Description
Technical field
The utility model relates to a kind of photovoltaic generation and uses combined transformer.
Background technology
Photovoltaic power generation technology is flourish in China in recent years, and the power transmission and transformation product consumption supporting with it also grows with each passing day, and the combined transformer that photovoltaic generation is special-purpose is because advantages such as its convenience with short production cycle, simple in structure, less investment have obtained extensive use.
Prior art have a following problem:
1, photovoltaic generation adopts the order font structural configuration of high and low pressure chamber and fuel tank with combined transformer; This kind arrangement is simple; When but the U.S.A that is directed against 1250KVA and following capacity becomes; The low-voltage side outlet insufficient space is often owing to providing enough spaces to waste natural resourcess such as more transformer oil and non-ferrous metal.
2, photovoltaic generation adopts the delta structure of high and low pressure chamber and fuel tank to arrange with combined transformer; The low-voltage side outlet space is sufficient; It is tightr that but high voltage load switch in the fuel tank and shunting switch are arranged, and the insulation distance that connects lead-in wire each other is difficult to guarantee.
3, photovoltaic generation often is placed in the above highlands of height above sea level 3000m, rarefaction of air, and insulation distance needs to revise, and the increase of insulation distance will certainly strengthen the volume that case becomes between the high and low pressure outlet, has also increased material consumption.
4, the top cover size between the high and low pressure too greatly can not one-shot forming, and cooperating between the two just needs to consider that checking the wind and fixing the shifting sand is rainproof.
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 photovoltaic generation of new arrangement mode to use combined transformer, and its technical scheme of taking is:
This combined transformer comprises and is the compact arranged transformer room of isosceles triangle, high-tension cable chamber, low-pressure chamber and operation with high pressure chamber; Wherein low-pressure chamber and operation with high pressure chamber are positioned at the front, right side of high-tension cable chamber, and the transformer room is positioned at the back, right side of high-tension cable chamber, and low-pressure chamber is positioned at the right side of operation with high pressure chamber; Be provided with transformer body and fuse fuel tank in the transformer room; Indoor lightning arrester, bushing and the insulator of being provided with of high-tension cable is provided with low-tension bushing and low-voltage cabinet in the low-pressure chamber, the operation with high pressure chamber is provided with shunting switch and on-load switch; The right-hand member of bushing is located in the fuse fuel tank; Shunting switch be located at transformer body above, on-load switch be located at the fuse fuel tank below, the low pressure top cover is connected through the U template with the high pressure top cover.
The utility model shunting switch be placed on transformer body above; The space of no longer occupying the transformer body next door; And on-load switch be placed on the fuse fuel tank below; Under not increasing the situation that case becomes the space, made full use of sufficient space below the fuse fuel tank, compact conformation is reasonable, solves the spatial constraints of low-tension bushing with on-load switch and shunting switch; The bushing of high-tension cable chamber utilizes the sufficient space of fuse fuel tank, even the phase spacing of bushing, lightning arrester and insulator still can be met the demands after the coefficient correction through height above sea level 3000m; The area of low pressure top cover and high pressure top cover more greatly can not one-shot forming, utilizes the transition of U template each other, and the left-right and front-back four direction of U template effectively connects with casing, and in addition sealing strip sealing realizes the good rainproof effect of checking the wind and fixing the shifting sand again.
Therefore the utlity model has compactness rational in infrastructure, production cost is low, performance is safe and reliable, overhaul characteristics easily.
