Abstract
The utility model discloses a transformer coil, which comprises a cylindrical tube body and a coil, wherein the tube body comprises an outer tube and an inner tube which are made of epoxy resin, the upper end and the lower end between the outer tube and the inner tube are sealed, the coil comprises a primary coil and a secondary coil, the primary coil and the secondary coil are respectively woundon the tubes, both ends of the coil are respectively provided with a connector, and the connectors are led out from both ends of the tube body. The utility model is characterized in that the primary coil and the secondary coil between the outer tube and the inner tube are filled with heat transfer materials. The utility model has the advantage of good heat transfer effect.
Description
Technical field
The utility model relates to a kind of transformer coil, the good transformer coil of specifically a kind of heat-transfer effect.
Background technology
The inboard of existing transformer coil is a cylindric body, and coil is wrapped in body, and body is that papery is a paper web, the outer again papery skin that coats after coil is wrapped on the paper web.The transformer of this structure is because body is a paper material, and skin also be papery, occurs easily seeping water after using a period of time, thereby causes coil short.For this reason, people adopt epoxy resin to make outer tube and interior pipe, and the sealed at both ends coil up and down between outer tube and the interior pipe twines respectively on inner pipe, and the two ends of coil are respectively equipped with joint, and joint is drawn from the two ends of body.This transformer has waterproof and dustproof, and is safe and reliable, long-lived advantage, but have the unfavorable shortcoming of radiating effect.
Summary of the invention
The purpose of this utility model provides the good transformer coil of a kind of heat-transfer effect.
The purpose of this utility model is achieved through the following technical solutions.
A kind of transformer coil, comprise cylindric body and coil, body comprises outer tube and the interior pipe of being made by epoxy resin, sealed at both ends about between outer tube and the interior pipe, coil comprises primary coil and secondary coil, and primary coil and secondary coil are wrapped in respectively on the pipe, and the two ends of coil are respectively equipped with joint, joint is drawn from the two ends of body, it is characterized in that: be filled with heat-transfer matcrial on primary coil between described outer tube and the interior pipe and the secondary coil.
The utility model compared with prior art has the following advantages.
Transformer coil described in the utility model all empty places between primary coil, secondary coil and primary coil and secondary coil all are filled with heat-transfer matcrial, the heat that coil produces can pass by heat-transfer matcrial at an easy rate, has good heat-radiation effect.
Description of drawings
Fig. 1 is the structural representation of the utility model transformer coil.
Embodiment
Below in conjunction with accompanying drawing the utility model transformer coil is described in further detail.
As shown in Figure 1, transformer coil described in the utility model mainly is made up of cylindric body and coil.Body by interior 1, in 2, outer 3 three bodys form, three bodys are made by epoxy resin, sealed at both ends composition two cavitys up and down of body.Coil is divided into primary coil 4 and secondary coil 5, and primary coil is positioned at the cavity near the center, and secondary coil is positioned at another cavity.Primary coil and secondary coil are wrapped in respectively on interior tube body and the middle tube body.Be filled with heat-transfer matcrial 6 on the primary coil of two cavitys and the secondary coil, this heat-transfer matcrial can pass the heat of primary coil and secondary coil generation soon, and product is played a very good protection.
