Description
Technical field
The utility model belongs to the service equipment field of high-tension power transmission and transformation equipment, relates in particular to a kind of vacuum oil-injecting machine.
Background technology
In the use procedure of high-tension current inductor or voltage transformer, along with the variation in service time increase and season, the oil level of the insulation oil product in it has decline, needs regularly to its oiling out of doors.For this a small amount of oiling, if adopt existing common oiling equipment to make oil and contact with air from the pouring orifice oiling meeting of current transformer or voltage transformer bottom, produce easily bubble, make the air content in the oil, water content increases, thereby the class of insulation of oil product is descended, also cause easily insulation fault between the mutual inductor coil when bubble enters; And if carry out oiling from the open top of outdoor high-voltage instrument transformer, often need to have a power failure, must remove top cover during operation, trouble very, and because aloft operation without secure support, has certain risk.
The utility model content
The utility model provides a kind of vacuum oil-injecting machine, its objective is to solve the prior art defective, provides a kind of safe and reliable, the vacuum oil-injecting machine that efficient is high.
The technical scheme that the utility model is dealt with problems is:
The utility model provides a kind of vacuum oil-injecting machine, comprising: oil tank 1, oil inlet pipe 2, gear pump 3, flowline 4, vacuum pump 5, drain line 6 and foot wheel 7; Wherein, described oil tank 1 bottom is equipped with foot wheel 7, drain line 6 is arranged on oil tank 1 bottom, 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 the 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, and the volume scale is installed on the shell of described oil tank 1.
Usefulness of the present utility model is:
This vacuum oiling machine to vacuumizing in the equipment, cuts out oil circuit by vacuum pump this moment, passes through oil pump smoothly to its oiling again.Vacuum line was closed in and vacuumized the bubble that can eliminate simultaneously when refueling this moment, and after oiling puts in place, vacuumized the gas guaranteed in the equipment oil and the gas in the equipment coil again and was taken out, and had guaranteed the insulating properties of insulating oil.Insulating oil can be stored in the fuel reserve tank, and fuel reserve tank is provided with respirator, can carry out drying to the air that enters fuel reserve tank, has guaranteed that insulating oil is not perishable, moisture in the insulating oil is remained in the claimed range, make insulating oil have good insulating properties.
Description of drawings
Fig. 1 is vacuum oil-injecting machine structure chart of the present utility model;
Comprise among the figure: oil tank 1, oil inlet pipe 2, gear pump 3, flowline 4, vacuum pump 5, drain line 6 and foot wheel 7.
Embodiment
As shown in Figure 1, the utility model provides a kind of vacuum oil-injecting machine, comprising: oil tank 1, oil inlet pipe 2, gear pump 3, flowline 4, vacuum pump 5, drain line 6 and foot wheel 7; Wherein, described oil tank 1 bottom is equipped with foot wheel 7, drain line 6 is arranged on oil tank 1 bottom, 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 the 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, and the volume scale is installed on the shell of described oil tank 1.
Specific embodiment:
The vacuum oil-injecting machine of present embodiment is mainly used in to oil-filled transformer, and current transformer injects insulating oil, also can be used for the oiling operations such as 110-550KV transformer, conduit, loaded switch.
The characteristics of present embodiment: after with vacuum pump the metal expander top above the instrument transformer being extracted into high vacuum first, insulating oil can arrive the required normal oil level of equipment by oil pipe bottom automatic oiling or by the oil pump oiling.Its advantage be in the oil-filled equipment residual gas particularly the gas between coil at first dividend take out, equipment refuels, makeup oil convenience, safety, oil are not polluted, and the original insulation property of energy assurance equipment are that vast power test overhauls the instrument that department welcomes.
The firmly oil pump method of operation of present embodiment
1, opens inlet valve on the oil storage tank, qualified insulating oil is injected in the oil storage tank, its oiling has two kinds, and a kind of method is that vacuum pump is opened, the vacuum of oil storage tank is reached-0.07Mpa about (vacuum meter supervision vacuum degree) qualified insulating oil will automatically suck in the oil storage tank.Another kind method is to start oil pump, and qualified insulating oil is extracted in the oil storage tank.
2, after oil tank is filled it up with oil, this oiling machine can be transported near the equipment of required oiling.
3, vacuum line, separator, conversion valve and oil inlet pipe and be connected on the equipment of required oiling notice that pipeline wants anchorage not with the leakage of oil of leaking gas.
4, open the crossover tee valve, the direction that becomes to bleed (this moment, oil circuit was closed) startup vacuum pump vacuumizes equipment (or metal expander of instrument transformer) and can bear the vacuum degree face decision final vacuum of taking out according to electric pressure and equipment.
5, after taking out that certain vacuum spends, stop vacuum pump.Conversion three energy valves become oil-feed to put, (this moment, exhaust pipe was closed).
6, open oil tank flowline or startup oil pump to the equipment oiling, 2-3 time so repeatedly, vacuumize oiling.
7, oiling vacuumizes equipment with this device behind normal oil level again.Purpose is that bubble in the equipment is taken out, and makes formation vacuum state in alveolus in the equipment.
8, finish to vacuumize after should close first a cutting valve plug, withdraw from again the air-extractor pipeline.
The beneficial effects of the utility model:
This vacuum oiling machine to vacuumizing in the equipment, cuts out oil circuit by vacuum pump this moment, passes through oil pump smoothly to its oiling again.Vacuum line was closed in and vacuumized the bubble that can eliminate simultaneously when refueling this moment, and after oiling puts in place, vacuumized the gas guaranteed in the equipment oil and the gas in the equipment coil again and was taken out, and had guaranteed the insulating properties of insulating oil.Insulating oil can be stored in the fuel reserve tank, and fuel reserve tank is provided with respirator, can carry out drying to the air that enters fuel reserve tank, has guaranteed that insulating oil is not perishable, moisture in the insulating oil is remained in the claimed range, make insulating oil have good insulating properties.
For making any technical staff in this area realize or to use the utility model, the above is described disclosed embodiment.To those skilled in the art; The various alter modes of these embodiment all are apparent, and the General Principle of this paper definition also can be applicable to other embodiment on the basis that does not break away from spirit of the present disclosure and protection range.Therefore, the disclosure is not limited to the embodiment that this paper provides, but consistent with the widest scope of the disclosed principle of the application and novel features.
