Abstract
The utility model discloses a dry-type three-phase power transformer, comprising winding epoxy resin circular columns. A transformer winding and a U-shaped copper tube are cast with epoxy resin and filler in each winding epoxy resin circular column, wherein the opening end of each U-shaped copper tube is connected with a connecting pipe through a syphon in a sealing mode to form a water delivery channel, one end of the water delivery channel is provided with a water inlet pipe, and the other end of the water delivery channel is provided with a water outlet pipe. The utility model provides the dry-type three-phase power transformer, water cooling is directly carried out on the transformer windings through the copper tubes buried in the epoxy resin, therefore, temperature raise during load operation of the power transformer is effectively reduced, and the volume of the transformer is reduced.
Description
Technical field
The utility model relates to a kind of power transformer, relates in particular to a kind of usefulness and is embedded in the dry type three-phase power transformer of the interior ventilating water pipe of epoxy resin with the cooling transformer heating in winding.
Background technology
The dry type three-phase power transformer is widely used in the power transmission and distribution of power industry.In the higher field of employment of many safety requirements (under the mine and naval vessel), the cooling of power transformer does not allow to adopt oil immersed type.Generally natural air cooled to the employing of dry type three-phase power transformer, these three kinds of types of cooling of forced air cooling and sky-water cooling, and these three kinds of types of cooling, dry type three-phase power transformer overall volume is bigger.In the comparatively valuable place of space requirement, in the distribution system as the power station, naval vessel, require the power transformer of equal capacity, shared spatial volume is the smaller the better.When power transformer dropped into load running, the loss heating mainly came from the copper loss of winding, and its value accounts for total losses about 85%.Therefore be necessary to improve the temperature rise when having cooling winding mode now, reduce the volume of transformer with the load running of reduction power transformer.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of dry type three-phase power transformer, and the temperature rise in the time of can effectively reducing the power transformer load running reduces the volume of transformer.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of dry type three-phase power transformer, comprise winding epoxy resin circular column, be cast with Transformer Winding and U-shaped copper pipe with epoxy resin and inserts in the described winding epoxy resin circular column, wherein, the openend of described U-shaped copper pipe seals to link to each other by bend pipe and tube connector and forms water transport channel, one end of described water transport channel is a water inlet pipe, and the other end is an outlet pipe.
Above-mentioned dry type three-phase power transformer, wherein, described water transport channel comprises the front and back two-way water transport channel that the Inlet and outlet water direction is opposite.
The utility model contrast prior art has following beneficial effect: the dry type three-phase power transformer that the utility model provides, be embedded in the epoxy resin copper pipe but by employing to the Transformer Winding direct water-cooling, temperature rise when effectively reducing the power transformer load running reduces the volume of transformer.

See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the dry type three-phase power transformer that the utility model provides comprises winding epoxy resin circular column 1, is formed by Transformer Winding 6 and U-shaped copper pipe 8 usefulness epoxy resin and inserts 7 cast; The open end of described U-shaped copper pipe 8 seals the formation water transport channel that links to each other by bend pipe 2 with tube connector 3, and an end of water transport channel is a water inlet pipe 4, and the other end is an outlet pipe 5.
Transformer Winding 6 and U-shaped copper pipe 8 usefulness epoxy resin and inserts 7 are cast for annulated column 1 in mould, U-shaped copper pipe 8 one ends are embedded in the resin, and other end opening stretches out the annulated column end face, form a phase winding (band cooling water pipe) of transformer (former limit or secondary), after finishing the transformer assembling, the open end of U-shaped copper pipe 8 is connected and sealed each U-shaped copper pipe 8 by bend pipe 2 and tube connector 3, two-way water transport channel before and after forming, one end of described water transport channel is a water inlet pipe 4, and the other end is an outlet pipe 5.
The utility model dry type three-phase power transformer is produced as follows: with particular manufacturing craft winding and copper pipe are poured into the epoxy resin circular column through vacuum pressure 1.; 2. the transformer assembling is shaped; 3. be divided in two parts, with copper bend pipe and connection copper pipe by specification accompanying drawing it be tightly connected respectively; 4. for guaranteeing the winding cooling evenly, front and back two-way Inlet and outlet water direction is opposite.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
