Description
Technical Field
The utility model relates to a transformer subassembly, concretely relates to no welding fin formula transformer belongs to transformer subassembly technical field.
Background
The transformer oil tank is a tank body which is used for installing a voltage transformation assembly and is filled with oil, the oil tank is connected with the oil conservator through a pipeline, and when oil is lacked in the oil tank, the oil in the oil conservator flows down along the pipeline and is supplemented into the oil tank, so that the oil tank is kept in a full oil state; meanwhile, when the load of the transformer is increased, the oil temperature is increased, the transformer oil expands and cannot be contained in the oil tank, the transformer oil can flow upwards along the pipeline and flows back to the oil conservator; the transformer oil tank in the prior art is mostly of a welded corrugated sheet heat dissipation structure, the oil tank needs to be regularly maintained and cleaned, and the transformer oil tank with a large appearance has the phenomena of welding failure, oil leakage and the like.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a no welding fin formula transformer adopts the whole shaping of oil tank, need not to weld the fin, and can fully dispel the heat to the box.
The utility model discloses a non-welding heat dissipation sheet type transformer, which comprises an oil tank, a high-voltage bushing and a low-voltage bushing which are fixed on the oil tank, wherein the inner sides of the high-voltage bushing and the low-voltage bushing are penetrated with leads which are electrically connected with a voltage transformation component in the oil tank; the oil tank is of an integrally formed structure; a heat radiation body is integrally formed outside the oil tank; the oil tank is integrally formed without welding radiating fins.
Further, the heat radiator comprises wide heat radiating fins and narrow heat radiating fins which are arranged at intervals; the adjacent wide radiating fins and the narrow radiating fins are arranged in a vertically staggered mode; a row of heat dissipation through holes are formed in the wide heat dissipation sheet; the heat dissipation through holes are formed in the outer portions of the narrow radiating fins, the whole box body can be dissipated through the wide radiating fins and the narrow radiating fins in a staggered mode, the heat dissipation through holes are formed in the wide radiating fins, the wide radiating fins can be subjected to convection heat dissipation, and meanwhile the narrow radiating fins can be dissipated.
Further, the high-voltage bushing and the low-voltage bushing are filled with solidified resin for coating the lead; an expansion compensator is arranged at the upper part of the inner side of the oil tank; the high-low voltage porcelain insulator sleeve is filled with cured resin for insulation instead, so that oil is not required to be filled; in addition, an expansion compensator is additionally arranged in the oil tank; the oil tank is always filled with oil, so that the installation of an oil conservator is directly cancelled.
Furthermore, the oil tank outside is sprayed with dustproof lacquer painting.
Compared with the prior art, the welding-free heat dissipation sheet type transformer has the advantages that the paint surface of the oil tank adopts a smooth paint surface material, so that dust falling can be avoided; in addition, the external welded radiating fins are removed, and the oil tank is integrally formed, so that the welding of the radiating fins and the oil leakage are avoided.
