Abstract
The utility model discloses a transformer comprising an oil tank (3) and a high-voltage coil (1) wound at the periphery of the a low-voltage coil (2), wherein the periphery of the high-voltage coil (1) is wrapped with at least one layer of insulating paper (4); and the inner side of each layer of the insulating paper (4) is provided with a plurality of oil passage supporting strips (5) parallel to the axis of the high-voltage coil (1). The transformer can reduce the distance between the high-voltage coil and the inner wall of the oil tank to be not less than 25mm, and can reduce the volume of the oil tank, thus reducing transformer oil in the oil tank and saving cost.
Description
Technical field
The utility model relates to transformer, specifically is a kind of transformer of oil immersed type.
Background technology
The high-voltage coil and low-voltage coil of the oil-filled transformer of 10KV electric pressure mostly is layered structure greatly at present, promptly adopt the coiling of high-voltage coil and low-voltage coil integral type, direct coiling high-tension coil makes each group (being phase-splitting) coil turn to an integral body continuously on the good low-voltage coil of coiling.Because the inside of high-voltage coil and low-voltage coil and fuel tank all has been full of transformer oil, but thermal diffusivity for insulation property between the inwall that guarantees high-tension coil and fuel tank and high-tension coil, distance between the inwall of its high-tension coil and fuel tank is general bigger, generally be not less than 35mm, cause the volume of fuel tank big like this, the transformer oil of inner dress is also many, cost is high.
The utility model content
The technical problems to be solved in the utility model is, thereby provides transformer oil in a kind of little minimizing of the volume fuel tank of fuel tank, save the transformer of cost.
The technical solution of the utility model is, a kind of transformer with following structure is provided, transformer, comprise fuel tank, be wound on the high-tension coil of low-voltage coil periphery, the periphery of described high-tension coil also is enclosed with one deck insulating paper at least, and the inboard of described every layer of insulating paper is provided with some oil duct stays of the axis of parallel high-tension coil.
After adopting above structure, the utility model compared with prior art, have the following advantages: because the periphery of described high-tension coil also is enclosed with one deck insulating paper at least, the inboard of described every layer of insulating paper is provided with some oil duct stays of the axis of parallel high-tension coil, the insulating paper that increases can increase the insulation property of high-tension coil and inner wall of oil tank, and the oil duct stay of setting up in the inboard of insulating paper makes transformer oil from flowing between the adjacent oil duct stay, can guarantee the heat radiation of high-tension coil, the spacing of high-tension coil and inner wall of oil tank can be dwindled like this, can reach and be not less than 25mm, can dwindle the volume of fuel tank, thereby reduce the transformer oil in the fuel tank, save cost.
As improvement, described some oil duct stays evenly distribute along the inboard of insulating paper, and transformer oil can be flow through from adjacent oil duct stay uniformly, guarantee the radiating effect of high-tension coil.
As improvement, the distance between the length direction center line of described adjacent two oil duct stays is 25mm, makes high-tension coil reach best radiating effect.
Description of drawings
Accompanying drawing 2 is the schematic diagram of insulating paper of the present utility model and oil duct stay.
As shown in the figure: 1, high-tension coil, 2, low-voltage coil, 3, fuel tank, 4, insulating paper, 5, the oil duct stay.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, transformer of the present utility model, comprise fuel tank 3, be wound on the high-tension coil 1 of low-voltage coil 2 peripheries, the periphery of described high-tension coil 1 also is enclosed with one deck insulating paper 4 at least, the inboard of described every layer of insulating paper 4 is provided with some oil duct stays 5 of the axis of parallel high-tension coil 1, changes the high-voltage tap lead tap into axial tap by radial simultaneously.
Described some oil duct stays 5 evenly distribute along the inside circumference of insulating paper 4.
Distance between the center line of the length direction of described adjacent two oil duct stays 5 is 25mm.
Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.Structure of the present utility model can have other variations, is not limited to said structure, and 5 of insulating paper 4 and oil duct stays are arranged on position rather than the whole periphery of high-tension coil 1 near fuel tank 3 inwalls as described.In a word, all various variations of being done in the protection range of the utility model product independent claims are all in protection range of the present utility model.
Claims (3)
1. transformer, comprise fuel tank (3), be wound on the high-tension coil (1) of low-voltage coil (2) periphery, it is characterized in that: the periphery of described high-tension coil (1) also is enclosed with one deck insulating paper (4) at least, and the inboard of described every layer of insulating paper (4) is provided with some oil duct stays (5) of the axis of parallel high-tension coil (1).
2. transformer according to claim 1 is characterized in that: described some oil duct stays (5) evenly distribute along the inside circumference of insulating paper (4).
3. transformer according to claim 1 is characterized in that: the distance between the center line of the length direction of described adjacent two oil duct stays (5) is 25mm.
