A kind of internal water cooling transformer high-tension coil, comprise and organize coil windings more, each coil windings is arranged in order from the top down, and described coil windings is formed by hollow conductor coiling, and the interlayer of described hollow conductor coiling is provided with insulating material; Often organize the top of the hollow conductor of coil windings and tail end to be equipped with water route and to lift one's head and circuit is lifted one's head.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
The internal water cooling transformer high-tension coil that the utility model provides, in hollow conductor, pass into deionization pure water in use and deionization source of purified water is continued to flow and carry out heat exchange through heat exchanger, taken away by the heat that coil windings produces, iterative cycles like this realizes the quick cooling of transformer coil.
Further, for effectively reducing the flow resistance of cooling water in high-tension coil, reducing the pressure of supply water of water system, improve product water route system reliability, is circuit connected in series relation and water route parallel relationship between each coil windings.
Further, as optimal technical scheme, the circuit of each top coil winding tail end is lifted one's head to lift one's head with the circuit at coil windings top, adjacent below and to be connected by wire.
Further, for cooling wire and taking away its heat produced, described wire is hollow conductor and wire is connected with hollow conductor inside.
Further, as optimal technical scheme, lift one's head and to be connected with water inlet collecting pipe in the water route at each hollow conductor top; Lift one's head and to be connected with water outlet collecting pipe in the water route of each hollow conductor tail end.

Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable; The corresponding same or analogous parts of same or analogous label; The term describing position relationship in accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of internal water cooling transformer high-tension coil, comprise many group coil windings 1, each coil windings 1 is arranged in order from the top down, described coil windings 1 is formed by single hollow wire 11 coiling, and the interlayer of described hollow conductor 11 coiling is provided with insulating material 14; Often organize the top 111 of hollow conductor 11 of coil windings 1 and tail end 112 be equipped with water route lift one's head 12 and circuit lift one's head 13; The circuit of each top coil winding 1 tail end 112 is lifted one's head and 13 to be lifted one's head with the circuit at coil windings 1 top, adjacent below 111 and 13 to be connected by wire 15, described wire (15) for hollow conductor and wire (15) be connected with hollow conductor (11) inside; Lift one's head and 12 to be connected with water inlet collecting pipe 21 in the water route at each hollow conductor 11 top 111; Lifting one's head and 12 to be connected with water outlet collecting pipe 22 in the water route of each hollow conductor 11 tail end 112, thus makes to be circuit connected in series relation and water route parallel relationship between each coil windings 1.
During use, as shown in Figure 3, lift one's head and 12 be connected in parallel between water collecting pipe 21 and water outlet collecting pipe 22 in the water route of each coil windings 1, cooling water flows into from the import S1 of water inlet collecting pipe, distribute to each coil windings 1, 12 inflows of lifting one's head from the water route at each coil windings 1 top are taken away by lifting one's head 12 outflows after each coil windings 1 from the water route of each coil windings 1 tail end the heat that coil produces, be connected with external refrigeration system by the outlet S2 of water outlet collecting pipe, through external refrigeration system, cooling water is cooled, cooled cooling water flows into the import S1 of water inlet collecting pipe again, the cooling of transformer coil is realized by constantly circulating.Between each parallel running in water route branch road, cooling water flow resistance is equal, and the flow between each parallel running in water route branch road distributes according to the water route length between each parallel running branch road, cross section, water route and coil loss.Because high-tension coil electric pressure is high, the number of turn is many, water route is long, adopt each point of intersegmental water route parallel running effectively can reduce the flow resistance of cooling water in high-tension coil, reduce the pressure of supply water of water system, improve product water route system reliability.
