Description
Technical field:
The utility model relates to a kind of electric power oiling equipment, particularly a kind of high-voltage mutual inductor air pressure oil supply machine at transformer station's oil immersion high-voltage mutual inductor.
Background technology:
At present, in electric power system, along with the continuous expansion of electrical network and perfect, power supply reliability requires higher, all need to carry out the insulating oil withstand voltage test during every two years high pressure preventive trial, get the insulation oil sample up to few 2～3 liters of insulating oils that need to consume in the instrument transformer at every turn,, after getting oil 2～3 times, just need repairing under the normal condition because expander has requirement to the quantity of oil in the instrument transformer.
Past, giving the instrument transformer repairing all is after having a power failure the expander fuel feeding valve at instrument transformer top to be opened, use the artificial pressure load push-pull that insulating oil is pressed in the expander, indicate in the normal position until oil level, use switching valve that the vacuum machine was inserted extracting vacuum about 1 hour then, make to form pressure-fired in expander and the instrument transformer, to reach the purpose of repairing.Adopt this method and these equipment, weak point is that (1) needs power failure to carry out, and interruption duration approximately needs 6 hours; (2) need safety means such as crane, and pollution face is bigger; (3) need large tracts of land to clear up, the cost height, and reduced power supply reliability, increased frequency of power cut.
The utility model content:
The purpose of this utility model is in order to overcome the deficiency of above-mentioned described oil supply machine, is not needing to use under the situation of other auxiliary equipment at short notice and just can finish the high-voltage mutual inductor air pressure oil supply machine that refuels to instrument transformer under the state that does not have a power failure and provide a kind of.
The technical solution of the utility model is achieved in that
A kind of high-voltage mutual inductor air pressure oil supply machine, comprise pressurized tank 1, pressure monitoring device 3, suppress equipment 5 and jockey 6, pressure monitoring device 3 with suppress the four-way 2 of equipment 5 and be connected with pressurized tank 1 by pressurized tank 1 top, the residue one logical air release valve 13 of installing of the four-way 2 at described pressurized tank 1 top, described pressurized tank 1 top-side is provided with tank filler sleeve 4, and described pressurized tank 1 bottom sides is provided with oil outlet 7.
Further, described jockey 6 one ends are connected with oil outlet 7, and the other end is connected with instrument transformer, and described jockey 6 is provided with delivery valve 8, air release valve 9 and secondary valve 10.
Further, described pressure monitoring device 3 is for showing the Pressure gauge of pressurized tank 1 internal pressure.
Further, the described equipment of suppressing is miniature electric compression pump or inflator.
The beneficial effects of the utility model are: under the situation that equipment does not have a power failure high-voltage mutual inductor is being carried out repairing, one group of instrument transformer of net cycle time only needed get final product in 25 minutes, and do not need other auxiliary equipment, improved power supply reliability, reduce frequency of power cut, fail safe, efficiency improve greatly, and working hour expense reduces greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of high-voltage mutual inductor air pressure oil supply machine, comprise pressurized tank 1, pressure monitoring device 3, suppress equipment 5 and jockey 6, a four-way 2 is installed at pressurized tank 1 top, four-way 2 tops are equipped with Pressure gauge 3, and the four-way two sides are separately installed with miniature electric compression pump 5 and air release valve 13; Described pressurized tank 1 top-side is provided with tank filler sleeve 4, is used for refueling in pressurized tank 1, is adding the sealing of oil back use bolt; Described pressurized tank 1 bottom sides is provided with oil outlet 7, oil outlet 7 is communicated with the instrument transformer 12 middle jockeys 6 that lean on, jockey 6 is a connecting pipe, is provided with delivery valve 8, air release valve 9 and secondary valve 10 above, and jockey is connected with priming valve 11 on the instrument transformer 12.
Operation principle of the present utility model is: when instrument transformer 12 oil levels are lower than the repairing of standard need, the insulating oil that at first in pressurized tank 1, adds 3/5 total measurement (volume), jockey 6 one ends are connected with oil outlet 7, the other end is connected with priming valve 11 on the instrument transformer 12, delivery valve 8, air release valve 9, secondary valve 10 and priming valve 11 are closed, open air release valve 9 this moment, in pressurized tank 1, be forced into 3～5 atmospheric pressure with miniature electric compression pump 5, stop to suppress, open pressurized tank 1 bottom delivery valve 8, oil is discharged from air release valve 9 from delivery valve 8 outflows and with the gas in jockey 6 pipes, no bubble is discharged and is closed air release valve 9 in air release valve 9, open the priming valve 11 of secondary valve 10 and instrument transformer 12, insulating oil in the pressurized tank 1 promptly can be mended in the instrument transformer 12, if Pressure gauge 3 shows that pressure reduces in the repairing process, when insulating oil does not inject in instrument transformer 12, can suppress once more until pressure and return to 3～5 atmospheric pressure, insulating oil in the pressurized tank 1 promptly can inject in the instrument transformer 12 continually, after the indication of instrument transformer 12 oil ga(u)ges is normal, the delivery valve 8 of closing presure jar 1 at first, close the priming valve 11 of instrument transformer 12 again, close the secondary valve 10 on the jockey 6 at last, jockey 6 and instrument transformer 12 are broken away from, and this process can repeat.
If no longer continue the next round repairing, break away from jockey 6 and instrument transformer 12, and on the delivery valve 8 buttoned-up bases, opening secondary valve 10 reclaims the oil in the jockey 6, opening air release valve 13 makes the pressure in the pressurized tank 1 reduce to atmospheric pressure, the repairing end-of-job, one group of three-phase repairing took time 25 minutes approximately.
Miniature electric compression pump in the present embodiment can replace with inflator.
