Description
Technical field
The invention belongs to the service equipment field of high-tension power transmission and transformation equipment, particularly relate to a kind of vacuum oil-injecting machine.
Background technology
In the use procedure of high-tension current inductor or voltage transformer out of doors, along with increasing service time and the change in season, the oil level of the insulation oil product in it has decline, needs regular to its oiling.For this small amount of oiling, if adopt existing common oiling equipment oil can be made to contact with air from the pouring orifice oiling bottom current transformer or voltage transformer, easy generation bubble, make the air content in oil, water content increases, thus the class of insulation of oil product is declined, also easily cause insulation fault when bubble enters between mutual inductor coil; And if carry out oiling from the open top of outdoor high-voltage instrument transformer, often need have a power failure, top cover must be removed during operation, extremely bother, and due to operation aloft, without secure support, there is certain risk.
Therefore, be developed vacuum oil-injecting machine to solve the problem, vacuum oil-injecting machine is vacuumized in equipment by vacuum pump, now closes oil circuit, then by oil pump smoothly to its oiling.Now vacuum line is closed.Vacuumizing bubble when simultaneously can eliminate oiling, and after oiling puts in place, then vacuumize and guarantee that the gas in equipment oil and the gas in equipment coil are taken out, ensure that the insulating properties of insulating oil.Insulating oil can be stored in fuel reserve tank, and fuel reserve tank is provided with respirator, drying can be carried out to the air entering fuel reserve tank, ensure that insulating oil does not absorb moisture content and particulate contaminant is not perishable, make water tariff collection in insulating oil simultaneously in claimed range, make insulating oil have good insulating properties.
But because condition is limited sometimes, the length of pipe of vacuum oil-injecting machine is inadequate, or high-tension current inductor or voltage transformer cannot be dismantled or inconvenience dismounting, then still need to carry out vacuum oil operation aloft.
Summary of the invention
The invention provides a kind of vacuum oil-injecting machine with lifter rack, its objective is and solve prior art defect, a kind of vacuum oil-injecting machine that can adapt to high-altitude oiling operation is better provided.
The technical scheme that the present invention deals with problems is:
A kind of vacuum oil-injecting machine with lifter rack, its drain line is arranged on tank bottom, oil inlet pipe is arranged on roof and is communicated with gear pump, flow divider is provided with between described oil inlet pipe and gear pump, described flow divider entrance is connected to oil inlet pipe, flowline is communicated with oil tank, vacuum pump is arranged on roof and is communicated with oil tank, it is characterized in that: below oil tank, be installed with square supporting plate, four angles of square supporting plate are dove tail, and four of square supporting plate angles are embedded in the trapezoidal rails erect at four respectively slidably, square supporting plate is fixed with motor, motor output shaft drives the driven wheel of connected gear reduction system end, driven wheel engages with a tooth bar erect of square supporting plate side.
Usefulness of the present invention is:
The engagement of driven wheel of the present invention and tooth bar can drive vacuum oil-injecting machine to be elevated, thus can carry out oiling to the high-tension current inductor of certain altitude or voltage transformer and need not dismantle high-tension current inductor or voltage transformer, and the dovetail groove of square supporting plate surrounding coordinates the stability that ensure that vacuum oil-injecting machine with trapezoidal rails.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention;
Fig. 2 is the schematic top plan view after the present invention removes vacuum oil-injecting machine.
Embodiment
As shown in Figure 1 and Figure 2, the invention provides a kind of liftable vacuum oil-injecting machine, its drain line 6 is arranged on bottom oil tank 1, oil inlet pipe 2 is arranged on oil tank 1 top and is communicated with gear pump 3, be provided with flow divider between described oil inlet pipe 2 and gear pump 3, described flow divider entrance is connected to oil inlet pipe 2, and flowline 4 is communicated with oil tank 1, vacuum pump 5 is arranged on oil tank 1 top and is communicated with oil tank 1, the shell of oil tank 1 is provided with volume scale.Square supporting plate 7 is installed with below oil tank 1, four angles of square supporting plate 7 are dovetail groove 71 form, and four angles of square supporting plate 7 are embedded in the trapezoidal rails 72 erect at four respectively slidably, square supporting plate 7 is fixed with motor 8, the output shaft of motor 8 drives the driven wheel 81 of connected gear reduction system (i.e. the reducing gear train of prior art) end, and driven wheel 81 engages with a tooth bar erect 82 of square supporting plate 7 side.
During use, starter motor 8 can make driven wheel 81 rotate, and drives square supporting plate 7 to rise along trapezoidal rails 72 or declines, also namely drive vacuum oil-injecting machine to rise or decline by the engagement of itself and tooth bar 82.
The vacuum oil-injecting machine of the present embodiment is mainly used in oil-filled transformer, and current transformer injects insulating oil, also may be used for the oil injection operation such as 110-550KV transformer, conduit, loaded switch.
The feature of the present embodiment: after first the metal expander top above instrument transformer being extracted into high vacuum with vacuum pump, insulating oil can by oil pipe bottom automatic oiling or by the normal oil level needed for oil pump oiling to equipment.Its advantage be residual gas in the oil-filled equipment gas particularly between coil first dividend take out, equipment refuels, makeup oil convenience, safety, oil are not polluted, and can ensure the original insulation property of equipment, are the instruments that vast power test maintenance department welcomes.
