Abstract
The invention discloses an oil-immersed power transformer, and relates to the field of electronic equipment. The oil-immersed power transformer comprises an oil tank, a primary coil and a secondary coil; the primary coil and the secondary coil are composed of multiple turns of coils and wound on an iron core; the primary coil, the secondary coil and the iron core are all immersed in the oil tank; a slip sheet is arranged in front of each of the primary coil and the secondary coil; the side of the oil tank is provided with two coil adjusting rings to connected with the slip sheets; two sleeves are arranged on the oil tank, the sleeves are respectively connected with the slip sheets. The oil-immersed power transformer has good insulating effect in the use process since the whole equipment is immersed in the oil; the slip sheet has the effect of regulating the pressure ratio of the transformer so that the transformer can no longer only boost pressure or reduce pressure invariably, but integrates the functions of boosting and reducing the pressure; the structure is simple, the function is various, and the practicability is strong.
Description
Technical field
The present invention relates to electrical equipment is and in particular to a kind of oil-immersed power transformer.
Background technology：
Transformator on the market to divide according to insulation and cooling condition, can be divided into oil-filled transformer and dry-type transformer.
For reinforced insulation and cooling condition, the iron core of transformator and winding all together with immerse in the fuel tank having filled transformer oil, this
Ensure that oil-filled transformer does not need to change oil in normal operation, greatly reduce the maintenance cost of transformator, extend simultaneously
The service life of transformator, but almost all of transformator all can only only be pressurized or reduce pressure, which limits product
Use.
