Abstract
The utility model discloses an insulating structure arranged between the primary and the secondary coils of a water-cooled transformer, which can ensure the stability of the structures of the coils and has good insulating effect. The insulating structure comprises two groups of epoxy struts which are evenly arranged on the peripheries of the coils; wherein, the first group of two epoxy struts (1) are fixed on the periphery of the inner primary coil (11); the second group of epoxy struts (2) are fixed on the periphery of the outer secondary coil (22); and the two groups of epoxy struts are partitioned from each other by insulating rubber tubes (3). The insulating structure is used in the field of transformers.
Description
Technical field
The utility model relates to a kind of transformer, especially relates to the insulation system between a kind of water-cooled transformer primary and secondary coil.
Background technology
The structure of transformer all is made up of interior winding coil, outer winding coil (or claiming primary and secondary coil) and iron core, and first, inferior need have insulation system that it is separated, to guarantee the operate as normal of transformer.At present, insulation system between the primary and secondary coil of general water-cooled transformer is that the secondary coil periphery in the outer ring evenly is provided with one group of epoxy stay, the epoxy stay is fixedlyed connected with the primary coil of inner ring by screw is fixing, another effect of screw is primary and secondary coil to be separated by come, to guarantee the insulation between primary and secondary coil.The insulation effect of this structure is not very desirable: the structure of coil is more loose, and accident easily is short-circuited in long-term use.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of insulation system that can make between loop construction water-cooled transformer primary and secondary coil stable, that insulation effect is good is provided.
The technical scheme that the utility model adopted is: the insulation system between water-cooled transformer primary and secondary coil described in the utility model comprises two groups of epoxy stays that evenly are arranged at the coil periphery, 2 peripheries that are fixedly set in the primary coil of inner ring of first group of epoxy stay wherein, second group of epoxy stay is fixedly set in the periphery of the secondary coil of outer ring, separates by insulation rubber tube between two groups of epoxy stays.
The beneficial effects of the utility model are: the insulation system between water-cooled transformer primary and secondary coil described in the utility model comprises two groups of epoxy stays that evenly are arranged at the coil periphery, 2 peripheries that are fixedly set in the primary coil of inner ring of first group of epoxy stay wherein, second group of epoxy stay is fixedly set in the periphery of the secondary coil of outer ring, separate by insulation rubber tube between two groups of epoxy stays, this structure not only can consolidate coil structure, and the more more effective insulation of primary and secondary coil, thereby make transformer in use more reliable.
