Abstract
The utility model relates to a vacuum oiling degasser capable of simultaneous vacuum-pumping and oiling for a high pressure oil immersion mutual inductor. The Vacuum oiling degasser capable of simultaneous vacuum-pumping and oiling for high the pressure oil immersion mutual inductor comprises a vacuum filling cup connecting a vacuum oiling system with a high pressure oil immersion mutual inductor. An air hole and an oil hole communicated with an inner cavity of the vacuum filling cup are arranged on the upper end surface of the vacuum filling cup. The oil hole is connected with an oil filling pipe of the vacuum oiling system. The air hole is connected with a vacuum-pumping pipe of the vacuum oiling system. An oil tube is arranged in the inner cavity of the vacuum filling cup. An inlet of the upper end of the oil tube is connected with the oil hole and the lower end outlet of the oil tube is arranged at the lower part of the inner cavity. Compared with the prior art, the design of the oil tube enables the arrangement an oil filling port to be on the lower part of the vacuum filling cup much lower than a vacuum-pumping pipe orifice which is the air hole. Oil is not pumped into the vacuum-pumping pipe in the process of vacuum-pumping and vacuum-pumping and oiling can be conducted simultaneously.
Description
Technical field
But the utility model relates to the high voltage oil immersion transformer vacuum oil degasser that a kind of limit vacuumizes marginal not oil.
Background technology
High voltage oil immersion transformer need to be connected to it in vacuum system and the injection system when oiling, first it is vacuumized, and then closes vacuum valve, opens fuel feeding valve and carries out oiling; After oiling a period of time, again product is vacuumized, close again vacuum valve after exhausting, open fuel feeding valve and carry out oiling.So circulate repeatedly until oil is filled with.
Because vacuum tube and oil fuel tube be at a distance of more closely and in one plane, under vacuumizing situation, during oiling, have a small amount of transformer oil and be inhaled in the vacuum pipe, therefore vacuumize with oiling and can not carry out simultaneously, vacuumize with oiling and need to hocket.And oiling when not vacuumizing, bubble in oil is difficult for deviating from, and the oiling effect is bad; If force disposable oil to be filled it up with, and then carry out vacuum outgas, so transformer inside especially the bottom gas since the liquid-level pressure effect be difficult to.
Summary of the invention
But technical problem to be solved in the utility model is the high voltage oil immersion transformer vacuum oil degasser that the present situation for prior art provides a kind of limit to vacuumize marginal not oil.
The utility model solves the problems of the technologies described above the technical scheme that adopts: but be somebody's turn to do the high voltage oil immersion transformer vacuum oil degasser that the limit vacuumizes marginal not oil, comprise the vacuum impregnating lubricating cup that connects vacuum oil system and high voltage oil immersion transformer, the upper surface of described vacuum impregnating lubricating cup is provided with oilhole and the pore with vacuum impregnating lubricating cup intracavity inter-connection, described oilhole is connected with the oil fuel tube of described vacuum oil system, and described pore is connected with the vacuum-pumping tube of described vacuum oil system; It is characterized in that being provided with oil pipe in the inner chamber of described vacuum impregnating lubricating cup, the upper end entrance of this oil pipe connects described oilhole, and the lower end outlet of oil pipe is positioned at described inner chamber bottom.
Preferably, described oil pipe is steel pipe, and the internal diameter of described oil pipe is 3-7mm.Control the speed of oiling by the diameter of oil pipe, tubing diameter is less, and oil injecting speed is slower, but the limit vacuumizes marginal not oil, thereby has also reached the degassed effect in immersion oil limit, limit.Can be according to electric pressure and product category different, the thickness of namely product insulation, the oil pipe that the immersion oil complexity is changed various different inner diameters are adjusted oil injecting speed, further improve the technical-economic index of this device.
The length of described oil pipe can be 2/3rds of described vacuum impregnating lubricating cup length.
The lower port of described oil pipe is obliquely installed with respect to the axis of oil pipe.
Compared with prior art, the utility model is by the design of oil pipe, and pouring orifice is arranged on bottom in the vacuum impregnating lubricating cup, is pore far below vacuumizing the mouth of pipe, so oiling can not be drawn into oil in the vacuum tube when vacuumizing, but the limit vacuumizes marginal not oil; And the design of thinner oil fuel tube in the preferred version then can be controlled oil injecting speed slower, has realized that limit at a slow speed vacuumizes marginal not oil, thereby has further guaranteed the degassed effect in immersion oil limit, limit, makes the insulating paper immersion oil thorough, and can not produce bubble in the immersion oil process.
Description of drawings
Fig. 1 is the floor map that the utility model embodiment uses state;
Fig. 2 is the floor map of the utility model embodiment sectional structure.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, but this limit vacuumizes the high voltage oil immersion transformer vacuum oil degasser of marginal not oil comprises vacuum impregnating lubricating cup 1, the upper surface of priming cup is provided with oilhole and the pore that is connected with vacuum impregnating lubricating cup inner chamber 11, wherein oilhole is connected with the oil fuel tube 21 of vacuum oil system 2, and pore is connected with the vacuum-pumping tube 22 of vacuum oil system 2.
Be provided with oil pipe 12 in the inner chamber 11 of vacuum impregnating lubricating cup, the upper end entrance of this oil pipe 12 connects above-mentioned oilhole, the lower end outlet of oil pipe 12 is obliquely installed with respect to the axis of oil pipe, and the outlet of oil pipe 12 is positioned at 1/3rd At The Heights of vacuum impregnating lubricating cup inner chamber, the internal diameter of oil pipe 12 is 5mm, and the internal diameter of oil pipe 12 is selected arbitrarily in the 3-7mm scope as required.
When high voltage oil immersion transformer 3 is carried out oiling, can vacuumize marginal not oil in the limit; Because oil-out is lower than and vacuumizes the mouth of pipe and distant, so oiling can not be drawn into oil in the vacuum tube when vacuumizing, add that oil fuel tube is very thin, oil injecting speed is very slow, realized that limit at a slow speed vacuumizes marginal not oil, thereby also reached immersion oil limit, limit degasifying effect, made dried insulating paper immersion oil thorough, and in the immersion oil process, can not produce bubble, reach best immersion oil effect.
