Description
Technical field
The present invention relates to the corrugation radiator of oil-immersed transformer and oil-immersed transformers.
Background technique
The lesser oil-immersed transformer of capacity not only has cooling function frequently with Full-sealing corrugated oil box structure, corrugated plate
Can, and its elasticity can compensate the transformer oil volume change because of caused by oil temperature lifting.Using Full-sealing corrugated oil box
Structure can be avoided transformer oil and air contact, aqueous vapor intrusion transformer is effectively prevented, to prevent transformer oil from insulating
Performance decline.But oil-immersed transformer capacity it is larger when, traditional Full-sealing corrugated oil box structure be unable to satisfy transformer dissipate
Heat can only add the Oiltank structure of oil conservater using gilled radiator to meet the expansion of the heat dissipation of transformer and transformer oil and receive
Contracting.However common oil conservater pasta is contacted with air, is easy sucking aqueous vapor.The oil conservater of other forms include bellow oil conservator,
Diaphragm oil conservater, capsule oil conservator etc., structure is complicated, expensive, and reliability is not so good as all-sealed structure.
Authorization Notice No. is that the Chinese patent of CN203941785U discloses a kind of Improvement type transformer gilled radiator, should
