The operating provisions for having crossed transformer are forced load down operation.First, constraint generator is contributed.Second, long-term high oil temperature operation,
Oil can be made to deteriorate decreasing insulating, reduce transformer service life, or even accident occurs.
Summary of the invention
In order to improve the running temperature of transformer, it is necessary to transformer is cooled down, the purpose of this utility model is that
A kind of improved oil immersed type self cooled transformer cooling system is provided, the original oily self-loopa type of cooling of transformer is changed to cool down
Water surface formula is cooling, improves the cooling cooling effect of transformer.
The purpose of this utility model is achieved in that a kind of improved oil immersed type self cooled transformer cooling system, including
One sweet-water tank, water pump, liquidometer, solenoid valve, atomizer, coating steel pipe, atomizer are divided into three groups, between level is uniformly distributed
Every being arranged above radiating fin of transformer at 30cm, radiator fan, the cooling fin lower section is arranged in radiating fin of transformer side
One water receiver is set, and water receiver is connected with sweet-water tank, and liquidometer and water pump are arranged in sweet-water tank, and water pump connects
Then coating steel pipe constitutes water pipe, and a solenoid valve is all respectively set on the water pipe of each group of atomizer, becomes
Temperature sensor in depressor is connected to PLC controller by data line, and PLC controller is connected to liquidometer, water pump and electricity
Magnet valve.
The utility model: 1, after improving, the type of cooling of transformer is changed into air-cooled, water cooling and is combined, and is able to achieve automatic control
System.2, demineralized water is used, it is possible to prevente effectively from transformer heat exchanger fin surface scale, cooling water partially recycled can be recycled, and be reduced
Water consume.3, summer transformer long term high temperature is avoided to run.It is effectively improved the operating condition of transformer, is prolonged the service life.
When the utility model is used, the lower demineralized water of power plant's temperature is filled into cooling water tank, it is anti-for using demineralized water to be
