Description
Technical field
The utility model relates to transformer equipment field, in particular to a kind of oil-immersed transformer resistant to high temperature.
Background technique
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondary
Grade coil and iron core (magnetic core).In electrical equipment and radio-circuit, it is commonly used for buck/boost, matching impedance, security isolation etc..
Major function has: voltage transformation, current transformation, impedance transformation, isolation, pressure stabilizing (magnetic saturation transformer) etc..It can divide by purposes
Are as follows: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-immersed transformer, list
Phase transformer, furnace transformer, rectifier transformer etc..
Existing transformer high-temperature resistant result is poor, if the long-term overlond running of transformer, coil heating keeps insulation gradually old
Change, just easily causes turn-to-turn short circuit, phase fault or shorted to earth.When short-circuit, in transformer can retardant insulating material and insulation
Oil will by high temperature, electric arc effect and decompose, expansion and then sharply increases inside transformer pressure so that gasification, seriously
When even result in Explosion of Transformer, this not only will affect normal power scheduling, but also will cause weight huge economic loss and people
Member's injures and deaths.
Utility model content
For above-mentioned deficiency in the prior art, the utility model provides a kind of oil-immersed transformer resistant to high temperature,
It is compact-sized, high temperature resistant, good heat dissipation effect, long service life.
In order to reach above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
A kind of oil-immersed transformer resistant to high temperature, comprising: fuel tank, the fuel tank are located at the top of pedestal, on the pedestal
Blower for cooling down surrounding air is installed, the blower is located at fuel tank two sides, and the fuel tank, which is surrounded by, to be vertically arranged, is in
The cooling fin of corrugated, the fuel tank upper and lower part are equipped with symmetrical thermally conductive cylinder, the thermally conductive cylinder two-by-two between be equipped with several heat absorptions
Piece, the fuel tank middle part are equipped with temperature and pressure and show table, and the fuel tank top is equipped with oil level gauge and pressure relief valve.
Further, the temperature and pressure shows alarm built in table.
Further, the fuel tank built-in temperature and pressure sensor, and the temperature and pressure sensor is electrically connected in temperature
Degree and pressure display table.
Further, spacing is 5-10CM, the external one layer of dustproof membrane of cooling fin, the dustproof membrane to the cooling fin two-by-two
It is made of polyurethane plastics.
The utility model has the following beneficial effects:
The corrugated cooling fin of the utility model can not only increase heat-dissipating distance, but also can increase the robustness of fuel tank, dustproof membrane
Not only can be dust-proof, but also insulation can be played the role of, and polyurethane plastics high temperature resistant, it prevents overtension from puncturing coil, extends
The service life of transformer, the cost of material is low, and heat resistance is good；Blower not only can be with the air around cooling oil box, but also can add
Speed heat gas disseminates；In addition, thermally conductive cylinder and heat absorbing sheet accelerate to absorb and propagate heat caused by fuel tank.
Detailed description of the invention
