Abstract
The utility model discloses a compact type high-power water-cooled transformer, which comprises a primary coil and a secondary body. The secondary body is equipped with an annular groove for holding the primary coil, the middle portion of the annular groove is equipped with a core column, a water passage connected with a circulating system is arranged inside the secondary body, concretionary insulating high-temperature-resistant materials are filled into the annular groove, and a cooling water diversion passage communicated with the water passage of the secondary body is arranged inside the core column. After utilizing the above technical scheme, the total primary coil is coated by epoxy resin through filling the total annular groove with the epoxy resin, and then when the water passage dissipates heat of the secondary body, heat generated by the primary coil is transmitted to the secondary body and cooling liquid inside the water passage through the surrounded epoxy resin. In addition, the core column is further equipped with the cooling water passage. Through the above structural improvement, the radiating efficiency of the water-cooled transformer is greatly increased, thereby guaranteeing work stability of the transformer.
Description
Technical field:
The utility model relates to a kind of high-power water-cooled transformer.
Background technology:
During work since the heating severity cause various electrical parameter instabilities, it is the technical barrier of puzzlement high-power transformer always, producer is in order to solve the heat dissipation problem of transformer at present, wind-cooling heat dissipating and water-cooling have been designed, consider radiating efficiency, what use morely on high-power transformer is water-cooled transformer, but the water cooling in prior technology transformer only is provided with heat-conducting layer simply at primary coil and secondary body contact position, and heat transfer efficiency is very low; In addition, the cooling of water-cooled transformer at present is only at secondary phosphor bodies, and ignored the cooling of stem stem.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of compact conformation, high-power water-cooled transformer that radiating efficiency is high are provided.
For achieving the above object, the technical scheme that the utility model provides is: the compact type large power water-cooled transformer, include primary coil and secondary body, secondary body is provided with the cannelure of placing for primary coil, the cannelure middle part is provided with stem stem, in secondary body, be provided with the water channel that is connected with the circulatory system, in cannelure, be marked with the heat conductive insulating exotic material that solidifies.
Described heat conductive insulating exotic material is an epoxy resin.
In the stem stem body, be provided with the cooling diversion channel that is connected with secondary body water channel.
After adopting technique scheme, by the full annular groove is filled with epoxy resin, make epoxy resin encase whole primary coil, water channel is when dispelling the heat to secondary body like this, and the heat that primary coil produces can be by epoxy resin all around the cooling fluid in secondary body of heat transferred and the water channel, in addition, on stem stem, also be provided with cooling water channel, after said structure improved, the efficient of the heat radiation of this water-cooled transformer was greatly improved, and guaranteed the job stability of transformer.
Description of drawings:
Fig. 1 is the structure chart of prior art water-cooled transformer;
Fig. 2 is the structure chart of the utility model water-cooled transformer.
Embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
The compact type large power water-cooled transformer of present embodiment, include primary coil 1 and secondary body 2, secondary body 2 is provided with the cannelure of placing for primary coil 13, cannelure 3 middle parts are provided with stem stem 4, in secondary body 2, be provided with the water channel 5 that is connected with the circulatory system, in cannelure 3, be marked with the heat conductive insulating exotic material 6 that solidifies.Described heat conductive insulating exotic material 6 is an epoxy resin.In stem stem 4 bodies, be provided with the cooling diversion channel 7 that is connected with secondary body water channel 5.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the present utility model.
