Abstract
The utility model provides a high-voltage coil of an oil-immersed transformer. The high-voltage coil comprises a coil body wound by copper foil. End insulation is formed on the end portion of the coil body, and layer insulation is formed on the side portion of the coil body. The outer layer of the coil body is wrapped by insulated spot gluing paper. A telescopic coil outgoing head is led out of the coil body in the axial direction. Due to the fact that the length of the outgoing head of the high-voltage coil of the oil-immersed transformer is adjustable, the size of the transformer is reduced, oil consumption is reduced, safety performance of operation of the transformer is improved, raw material consumption is reduced and welding pollution is avoided.
Description
Technical field
The utility model relates to the power transmission and transformation technical field, particularly a kind of oil-filled transformer high-tension coil.
Background technology
In oil-filled transformer, the lifting one's head by with the leftover of bolt of cloth and tighten with lock tightly of transformer high-voltage coil, this winding protruding head is to be drawn by coil amplitude direction, and its lead-in wire space hold is big, makes that volume of transformer is big and the transformer oil loss is higher.
And this high-tension coil is lifted one's head length and is fixed, and need be welded to connect high-voltage connection by copper bar, and this Welding Structure is owing to need carry out operation inconvenience in the smaller transformer of space; The spark that produces during welding is splashed on the Transformer Winding easily, influences its operate as normal, and in addition, producing a large amount of harmful substances during welding also has bigger pollution to environment.
The utility model content
The purpose of this utility model is to propose a kind of lead-in wire to take up room for a short time, and raw materials consumption is low and and do not have an oil-filled transformer high-tension coil that welding is polluted.
For achieving the above object, the utility model proposes a kind of oil-filled transformer high-tension coil, the coil body that comprises the Copper Foil coiled, the end of described coil body is provided with the end insulation, the sidepiece of described coil body is provided with layer insulation, the skin of described coil body is enclosed with the insulating point gummed paper, and it axially leads to telescopic winding protruding head described coil body upper edge.
Further, in above-mentioned oil-filled transformer high-tension coil, the end of described coil body also leads to three taps be used to the cable that is connected to high-voltage connection, these three taps axially drawing along the coil body.
Further, in above-mentioned oil-filled transformer high-tension coil, described coil body is the double-layered cylinder formula.
Further, in above-mentioned oil-filled transformer high-tension coil, described winding protruding head and three taps are by tightening band and strap tighten.
The utility model oil-filled transformer high-tension coil has reduced volume of transformer because lifting one's head adjustable length, has reduced the oily loss of transformer, has improved the security performance of transformer work, and has reduced raw materials consumption and and do not have welding and pollute.
Description of drawings
Fig. 1 is the structural representation of the utility model oil-filled transformer high-tension coil one embodiment.
Fig. 2 is another structural representation of Fig. 1 mesohigh coil.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the utility model oil-filled transformer high-tension coil, the coil body 1 that comprises the Copper Foil coiled, the end of described coil body 1 is provided with end insulation 2, the sidepiece of described coil body 1 is provided with layer insulation 3, the skin of described coil body 1 is enclosed with insulating point gummed paper 4, and it axially leads to telescopic winding protruding head 12 described coil body 1 upper edge.
Wherein, described winding protruding head 12 is the former lead of coil body, the variable-length of described winding protruding head 12, and it can be drawn from bushing according to the position of switch (not shown), and is electrically connected on the cable (not shown) of transformer high-voltage lead-in wire.
The end of described coil body 1 also along the coil body axially lead to three taps 14, it is connected to the cable of high-voltage connection.
Described coil body 1 is the double-layered cylinder formula, and described winding protruding head 12 and three taps 14 are by tightening band and strap (not shown) tighten.
Than prior art, the winding protruding head variable-length of the utility model oil-filled transformer high-tension coil can be adjusted flexibly according to the position of switch; Coils in transformers lift one's head and tap by axially drawing, it has dwindled the lead-in wire space at Width, has reduced volume of transformer, has also reduced the oily loss of transformer.And this high-tension coil has upwards reduced the distance of lead-in wire and transformer tank wall at its width of cloth, thereby has reduced the probability of lead-in wire to the discharge of transformer tank wall, has improved the security performance of transformer work.
In addition, winding protruding head directly is electrically connected on high-voltage connection, need not to descend again the copper bar welding, has reduced raw materials consumption and welding pollution.
The utility model oil-filled transformer high-tension coil has reduced volume of transformer because lifting one's head adjustable length, has reduced the oily loss of transformer, has improved the security performance of transformer work, and has reduced raw materials consumption and do not had the welding pollution.
Here description of the present utility model and application is illustrative, is not to want with scope restriction of the present utility model in the above-described embodiments.Here the distortion of disclosed embodiment and change is possible, and the various parts of the replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present utility model or substantive characteristics, and the utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.Under the situation that does not break away from the utility model scope and spirit, can carry out other distortion and change to disclosed embodiment here.
