Background technology
Send out the power supply power equipment, major part is to make amboceptor with insulating oil to fill three effects greatly of guaranteeing insulation of electrical installation, heat radiation, extinguishing arc.What electric power oil-filled equipment oil mass was big is main transformer and reactor etc., oil mass is less be current transformer and voltage transformer (85～2000kg), main transformer conduit, oil switch conduit etc.They play extremely important effect equally in transformer station, also are high pressure, the extra-high tension units of 110～220～500～750KV, if lack one of them or equipment is defective can not generate electricity equally and powered operation.
Send out power supply maintenance, testing crew, be often to equipment, the monitoring chemical examination of drawing oil sample, make the said equipment oil starvation like this, as if not being added to normal oil level, then cause poor insulativity, can not put into operation, otherwise burn out equipment or blast.And be filled in medium insulating oil in the electric power filling type high-tension apparatus and require very strictly, meet electric power GB7595-2008 and electric power preliminary examination prerun DL/T596-1996 requirement.For making the insulating oil puncture voltage, moisture and air content etc. will reach criterion of acceptability.Because gas content of oil is 10～12%, producing bubble in oiling can influence insulation property equipment may be burnt and explode, so must be to vacuumize oiling, not vacuumizing can't repairing.And because of gas being arranged interior, oil is added also and will be ejected, even a small amount of adding also is that insulation property are poor, testing of equipment is defective.
Present stage, the most original way was, with shoulder pole the stainless steel ripple being compressed oil storage box automatically by 2-4 workman mentions and forms under the negative pressure condition, oil could be added insulating oil from the ripple oilhole, so repeatedly promote operation repeatedly, oil subsidy could be annotated qualified position, but refuel because of artificial physical limited dangerous, and it is bad to add oily effect, again can't vacuumize degassing.
For addressing the above problem, be to adopt vacuum pump to add hand oil pump, shortcoming is that hand pump is often malfunctioning, the not enough and oil storage tank unprotect device of pressure, oil is normal to become bad, and moisture, dielectric strength are defective.
Summary of the invention
The utility model provides a kind of vacuum oil supply machine, purpose is to solve the prior art problem, provide a kind of convenience power equipment to be carried out the oil supply machine of repairing, this oil supply machine pressure can make oil mend smoothly in the power equipment, and insulating oil not perishable, various index in oil supply machine all meets the requirements always simultaneously.
The utility model technical scheme that adopts of dealing with problems is:
The vacuum oil supply machine includes oil storage tank, and oil storage tank upper end one side is provided with vacuum pump, is connected with vacuum tube by the vacuum tube valve on the vacuum pump, and vacuum tube is provided with Pressure gauge.Oil storage tank upper end opposite side is provided with oil pump, oil pump is connected with two oil circuit pipes by the oil circuit tube valve, one of them oil circuit pipe stretches in the oil storage tank, another oil circuit pipe is connected with the port of triple valve respectively with vacuum tube, another port of triple valve connects petroleum pipeline and vacuum tube, and the oil circuit pipe that wherein is connected with triple valve is provided with Pressure gauge.
Also be provided with the respirator that is used for dry air on oil storage tank, the respirator pipeline is provided with valve.
The oil storage tank lower end is provided with sewage draining exit, and is provided with the blowdown plug.
Described oil storage tank is provided with the oil mass observation window.
Described oil storage tank lower end is equipped with universal wheel.
Described oil circuit pipe, vacuum tube and the petroleum pipeline that is connected with triple valve is transparent wired hose.
The beneficial effects of the utility model: this vacuum oil supply machine to vacuumizing in the equipment, is closed oil circuit by vacuum pump this moment, passes through oil pump more smoothly to its repairing.Vacuum line was closed in and vacuumized the bubble that can eliminate simultaneously when refueling this moment, and after repairing 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 insulation performance.
