Abstract
The utility model discloses a restoring device for power transformer oil, which comprises a filter tank and a sealing tank. An outlet of the filter tank is communicated with an inlet of the sealing tank through a control valve, the outlet of the sealing tank is communicated with a finished product tank through the control valve, the inlet of the filter tank is provided with the control valve, an upper end of the sealing tank is communicated with a vacuum pump of the control valve through a vacuum pipe, and a heating mechanism is arranged on the sealing tank. According to the restoring device, a treatment on water removal from heating transformer oil is carried out under a vacuum condition, and the water removal from transformer oil can be completed once, thereby the insulation strength of transformer oil is increased, additionally, residues in transformer oil are filtered via a filtration of the filter tank, so that transformer oil is purified, and the recycle of transformer oil is facilitated.
Description
Technical field
The utility model relates to a kind of transformer attending device, particularly relates to a kind of prosthetic device of electric power transformer oil.
Background technology
Owing to move in the environment in the open for a long time, add itself because of the variations in temperature that the variation of load causes, will form draught head inside and outside the transformer, thereby cause air flow, moisture will take advantage of the occasion to get in the transformer.When moisture acquired a certain degree, the insulation property of transformer oil will reduce, and then caused puncture, short circuit phenomenon, the safety of harm transformer and network system.For addressing this problem, mainly utilize drier that transformer oil is removed water treatment at present, still, and because after the drier use, its water absorption can weaken, thereby need carry out multiple times of filtration usually, complicated operation, and be prone to cause quality problems because of the personnel operation reason.
The utility model content
The utility model technical problem to be solved is: overcome the deficiency of prior art, provide a kind of reasonable in design, drying effect good and can guarantee the prosthetic device of the electric power transformer oil of transformer oil quality.
The technical scheme of the utility model is: a kind of prosthetic device of electric power transformer oil; Contain filtering tank and hermetically sealed can; The outlet of said filtering tank is communicated with the import of said hermetically sealed can through control valve, and the outlet of said hermetically sealed can is communicated with the finished product jar through control valve, and the import of said filtering tank is provided with control valve; The upper end of said hermetically sealed can is communicated with vacuum pump through vacuum tube and control valve, and said hermetically sealed can is provided with heating arrangements.
Said heating arrangements contains heating tube and heat-insulation layer, and said heating tube is coiled on the said hermetically sealed can, and said heating tube is outside equipped with said heat-insulation layer.Be provided with filter and adsorption plate in the said filtering tank.
The beneficial effect of the utility model is:
1, the utility model removes water treatment to the transformer oil of heating under vacuum condition, because water flashes to gas easily under vacuum state, and the moisture of heating more is prone to evaporation; Thereby can once accomplish dewatering of transformer oil, the dielectric strength that has improved transformer oil is high, in addition; Filtration through filtering tank; Impurity in the transformer oil is filtered, and has purified transformer oil, helps transformer oil and utilizes.
2, the utility model is enclosed with heating arrangements on hermetically sealed can, can make whole hermetically sealed can firing rate fast and heating uniformity good, helps the moisture rapid evaporation, reduces the repair time of transformer oil.
3, the utility model is reasonable in design, drying effect good and can guarantee the transformer oil quality, has good economic benefit after the popularization.
Description of drawings
Fig. 1 is the structural representation of the prosthetic device of electric power transformer oil.
Embodiment
Embodiment: referring to Fig. 1, among the figure, 1-finished product jar, 2-heating arrangements, 3-hermetically sealed can, 4-filtering tank, 5-vacuum pump.
The prosthetic device of electric power transformer oil contains filtering tank 4 and hermetically sealed can 3; Wherein: the outlet of filtering tank 4 is communicated with the import of hermetically sealed can 3 through control valve; The outlet of hermetically sealed can 3 is communicated with finished product jar 1 through control valve; The import of filtering tank 4 is provided with control valve, and the upper end of hermetically sealed can 3 is communicated with vacuum pump 5 through vacuum tube and control valve, and hermetically sealed can 3 is provided with heating arrangements 2.
During use, transformer oil gets into filtering tank 4 through control valve, through behind the multi-filtering; Transformer oil gets into hermetically sealed can 3, and 2 pairs of hermetically sealed cans 3 of heating arrangements heat, and vacuum pump 5 starts simultaneously; Make transformer oil rapid evaporation under high-temperature low-pressure, once accomplish dewatering of transformer oil.
