Description
Technical field
It the utility model is related to transformer production device, more particularly to transformer production vacuum oiling device.
Background technology
Transformer is very extensive in the use of power industry, and transformer is to change alternating current using the principle of electromagnetic induction
The conversion equipment of pressure, transformer oil have substantially obtained widely should as the dielectric and cooling medium of oil-filled transformer
With, oil-filled transformer general assembly capping after need carry out injection transformer oil operation.Oiling rank in transformer vacuum oil
Section is highly important, it is desirable to oiling stops oiling when highly reaching pasta away from the range of transformer tank tops 100-200mm,
But it is difficult accurately to be controlled in actual mechanical process.
Traditional method is the height for judging inside transformer oil level, mainly uses time recording transformer case temperature, determines
When the methods of beaing the transformer case sound with small tool.The position that inside transformer insulating oil floods, the temperature of shell can be high
Some, sound when tapping shell can be dull, and the position that insulating oil does not flood, skin temperature can be lower, taps outer
Sound during shell can be clearer and more melodious.Or observe transformer oil by connecing a transparent plastic tube in transformer side wall
Liquid level in case, there is installing/dismounting trouble in this device, and this transparent plastic tube is very thin, during oiling, thoroughly
Liquid level in bright plastic tube and its easily it is affected and up and down, judges to become by the liquid level in lucite pipe
Actual liquid level in depressor acquires a certain degree of difficulty.If operating personnel cause the full oil of transformer to cause transformer because of liquid level misjudgment
Oil sprays, and is very easy to be sprayed onto and checks with the operating personnel of liquid level.In addition, transformer oil of the prior art is usually
Directly entered by oil pipeline in transformer shell body, it is difficult to find bubble present in transformer oil or impurity.
