Compared with the prior art, the invention provides a transformer oil tank for slowing down the aging of a rubber mat, which has the following beneficial effects:

1. this a transformer tank for slowing down cushion ageing uses through the cooperation of drawing liquid fan and swash plate, and at the in-process of transformer work, advance oil pipe and fill the oil tank with the thermal fluid of absorption in, the condenser through setting up in the oil tank is to the fluid cooling, discharges fluid through an oil pipe afterwards, forms the circulation.

In the working process of the transformer, once the load is increased, more heat is generated, so that oil inside the oil inlet pipe absorbs more heat, when the oil is discharged into the oil tank, mercury in the mercury tank is heated and expands due to the fact that the temperature of the oil is higher than the normal level, the mercury plate is pushed to slide inside the liquid guide pipe, the horizontal screw is driven to move and is in meshing transmission with the vertical screw, the vertical screw rotates and is in meshing transmission with the rotating shaft, the liquid pumping fan is driven to rotate, the liquid pumping fan pumps the cooled oil near the condenser and hits the surface of the inclined plate, the cooled oil is conveyed to the position near the hollow rubber pad through emission of the inclined plane of the inclined plate, sudden heat of the hollow rubber pad is prevented, the sudden heat is an important factor influencing the aging of the rubber pad, the heating rate of the hollow rubber pad is buffered by the cooled oil, and heat damage to the rubber pad is effectively reduced, therefore, the effect of slowing down the aging rate of the rubber mat in the use process of the oil tank is achieved.

2. This a transformer oil tank for slowing down rubber mat is ageing uses through the cooperation of extrusion spring and telescopic link, and at the long-term in-process that uses of oil tank, the inevitable emergence of hollow rubber mat is ageing, leads to the whole softness of hollow rubber mat, and then makes its inside atmospheric pressure reduce.

Because when hollow cushion is not ageing, accept the pole through the surface extrusion and cause the extrusion to the extrusion spring, after hollow cushion is ageing to take place the flaccidity, extrusion spring extrusion accepts the pole and makes it remove to hollow cushion direction, it drives the metal pole removal of side to accept the pole, inside sliding into the wire that opens a way, make the wire that opens a way circular telegram, and then lead to controlling the motor start of telescopic link, the telescopic link removes to being close to hollow cushion direction, aerify hollow cushion through the air duct, make the flaccidity hollow cushion tighten again, and its inside atmospheric pressure increase resumes normal size.

Because it is normal when hollow cushion atmospheric pressure to detect the gasbag, can extrude the air pressure bar, extrude the kelly right through the arch of its side, and then go deep into between the dog that telescopic link left side set up, block the kelly, and when hollow cushion is soft, the kelly can move left under the effect of the restriction lever that sets up at its surface, be not blockking the telescopic link, so when aerifing hollow cushion, when hollow cushion resumes normal atmospheric pressure, the kelly will block the telescopic link once more, make hollow cushion can not excessively inflate, meanwhile, hollow cushion will accept the pole jack-up, make the metal pole break away from the wire that opens circuit, the telescopic link is not removing.

Based on the expression, the hollow rubber mat is inflated again and tightened after being aged and softened, so that the service life of the rubber mat is greatly prolonged, and the effect of prolonging the service life of the rubber mat is achieved.
