Dispel the heat the oil tank internal insulation oil -transferring of transformer in heat abstractor through the oil pump, can reduce the temperature of oil tank internal insulation oil, avoid the too high transformer inner part that leads to the fact of oil temperature to damage. The utility model has the advantages of simple structure is compact, the radiating effect is good, utilize heat abstractor reduced insulation oil temperature, can effectively improve the factor of safety of transformer, guarantee the oil -immersed transformer safe operation.
Description
Technical field
This utility model relates to transformer technology field, particularly relates to the oil-filled transformer of a kind of improvement.
Background technology
Owing to transformator factor such as loss heating, the rising of ambient temperature, the load current increase of iron core and winding in running all can cause transformer oil temperature rise, generally speaking the coil windings of transformator, particularly low pressure winding is due to electric current maximum when transformator runs, produced heat is most, and temperature is the highest.And the transformator of prior art, its radiating effect is unsatisfactory, when temperature of oil in transformer is higher than more than 95 DEG C, this may result in some parts damages in transformator or transformator, and the parts in transformator once damage, it is accomplished by power failure to change damage parts, not only user is affected, but also the operating cost of transformator can be increased.
Utility model content
Technical problem to be solved in the utility model is to provide the oil-filled transformer of a kind of improvement, and it is simple and compact for structure, can be effectively improved transformator radiating effect.
For solving above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of oil-filled transformer of improvement, including fuel tank, case lid and the iron core being located in fuel tank and coil, described fuel tank is arranged over conservator, bottom is provided with bleeder plug, and described fuel tank is provided with oil inlet pipe and flowline, and described flowline is connected with oil inlet pipe by heat abstractor.
Preferably, described heat abstractor includes radiator and oil pump, and described flowline is connected through oil pump and after running through radiator with oil inlet pipe, and described radiator is connected with refrigerator.
Preferably, being provided with sealing gasket between described fuel tank and case lid, described case lid is formed around downward flanging.
Preferably, described conservator is provided with liquidometer.
Preferably, described fuel tank inner bottom part correspondence iron core position is provided with cushion, and described tank bottoms is arranged on transformer base by damper element.
Use and have the beneficial effects that produced by technique scheme: dispel the heat in insulating oil in the fuel tank of transformator being delivered to heat abstractor by oil pump, it is possible to decrease the temperature of insulating oil in fuel tank, it is to avoid high oil temperature causes inside transformer part to damage.This utility model has simple and compact for structure, the advantage of good heat dissipation effect, utilizes heat abstractor to reduce insulating oil temperature, can be effectively improved the safety coefficient of transformator, it is ensured that oil-filled transformer safe operation.
