Technical field
The utility model relates to a kind of transformer oil protection system, specifically a kind of transformer oil protection system of full-sealed transformer.
Background technology
In prior art, the operating pressure that full-sealed transformer corrugation radiator bears by manufacturing process and the restriction in useful life, the bearing pressure and can not be greater than rated value of corrugation radiator.The dilation of corrugation radiator can normally work in the elastic range allowed, but because the temperature difference is comparatively large or transformer body produces gas interior pressure increase, corrugated plate exceedes elastic range distortion, can be split up ooze, oil leakage phenomenon.When the temperature decreases, corrugated plate elastic range exceedes setting, causes shrinking reduction, and fuel tank volume increases, and pasta certainly will reduce and exposes shunting switch, part iron core and coil, and insulation breakdown phenomenon occurs; Full-sealed transformer pasta fluctuation air is discharged and inspiration from case lid seam in addition, because upper strata oil temperature is very high, oil is oxidized soon.
Utility model content
The purpose of this utility model is the transformer oil protection system providing a kind of full-sealed transformer, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of transformer oil protection system of full-sealed transformer, comprise automatic oil return valve, oil conservator, breathing gas tank, piston, dividing plate, block, automatic oil draining valve, oil exit pipe, full-sealed transformer, fan and oil return pipe, the side of described full-sealed transformer is fixed with oil conservator, oil conservator is communicated with full-sealed transformer inner chamber by oil return pipe with top oil exit pipe by bottom, wherein the inside of oil conservator is stretched in one end of top oil exit pipe, the junction of described top oil exit pipe and oil conservator arranges automatic oil draining valve, and arranges fan in the side of oil return pipe; The junction of described oil return pipe and oil conservator is provided with automatic oil return valve; The pore at described oil conservator top is connected by pipeline breathes gas tank; the middle part of described breathing gas tank is divided into an annular seal space and an open-cavity by dividing plate; annular seal space is communicated with bottom open-cavity; piston is provided with in described open-cavity; described annular seal space connects the pore at Oil Tank top, in annular seal space, arrange protective gas.
As further program of the utility model: described bottom is helical form by oil return pipe.
As further program of the utility model: the pipeline material of described oil return pipe adopts aluminium alloy.
As further program of the utility model: top and the bottom of described open-cavity are equipped with block.
As further program of the utility model: described protective gas adopts nitrogen or helium.
Compared with prior art, the beneficial effects of the utility model are: by arranging the oil conservator of connection in the side of full-sealed transformer, realize the adjustment of full-sealed transformer internal pressure, avoid internal component to expose by repairing puncturing, the oxidized phenomenon such as electric arc; Breathing gas tank is set in the side of oil conservator simultaneously; protective gas is injected by breathing in gas tank; can effectively avoid transformer oil oxidized; it also avoid oxygen enters in full-sealed transformer; and breathe and in gas tank open-cavity, piston is set can moves freely according to pressure, reach pressure controlled effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
