Description
Technical field
The utility model relates to a kind of each high-power station, transformer station, oil depot carry out medium damage filtration treatment to transformer oil medium damage filter that is used for.
Background technology
Transformer oil in the power transformer slightly aging or contaminated after, the oil medium decreases and all can raise, handle transformer oil medium damage at present and mainly contain following dual mode: a kind of mode is transformer oil to be put in the oily tank handle, by pressure type oil filter and vacuum oil-filter series connection, heat by vacuum oil-filter, the pressure type oil filter adds absorption type filter paper and carries out circular treatment, treat oily medium decrease qualified back by technological requirement with the transformer oil injection transformer; Another kind of mode is to handle with the mode of extracorporal circulatory system, equally by pressure type oil filter and vacuum oil-filter series connection, oil product earlier adds absorption filter paper by the pressure type oil filter and carries out preliminary treatment, then by the vacuum oil-filter heating, vacuumize after injection transformer still, up to handle qualified till.In existing processing mode, because vacuum oil-filter heater power is not enough, oily temperature is difficult to reach requirement, adds that vacuum oil-filter work needs the professional uninterruptedly to nurse, and the operating time is long, intensity is big.Traditional pressure type oil filter is a unenclosed construction, and work needs control oil stream and oil pressure, also needs the professional to nurse, otherwise oil product very easily overflows, and not only contaminated environment is handled also quite trouble, and the oil product injection transformer of wherethrough reason also must carry out vacuum treatment, has also increased treatment process.
Summary of the invention
Technical problem to be solved in the utility model is, provide need not in a kind of simple in structure, easy to operate, oil product circulating treatment procedure to nurse, transformer oil medium that labor intensity of operating staff is low decreases filter.
Transformer oil medium of the present utility model decrease filter include be used for the pending oil product of inspiration oil-in and be used for exporting the oil return opening of handling the back oil product, also include the oil filler and the fuel outlet that are communicated with extraneous fuel tank, also has a closed fuel tank in the device, filter bed is installed in closed fuel tank, and the filter core of filter bed can be extracted out from a side of closed fuel tank; Above-mentioned oil-in is connected with the filter bed oil-in through an oil-feed break valve F1, an oil pump and a heater successively, the filter bed oil-out then is connected with oil return opening through an oil return break valve F5, the filter bed oil-out also is connected with above-mentioned fuel outlet through the break valve F6 that drains the oil, and above-mentioned oil filler then adds oil cut-off valve F2 through one and is connected between above-mentioned oil-feed break valve F1 and the oil pump; Described closed fuel tank has a fuel tank import, a fuel-tank outlet and a bleeding point, the fuel tank import of closed fuel tank is connected with the filter bed oil-out through a break valve F4, the fuel-tank outlet of closed fuel tank is connected to the oil-in of above-mentioned oil pump through a break valve F3, and the bleeding point of closed fuel tank is connected with a vacuum pump through a break valve F7 and a gs-oil separator successively.
The utility model is owing to adopt the structure that filter bed is installed in the closed fuel tank, and it is excessive that oil product can not produced in circulating treatment procedure, not only easy to operate, and need not special messenger's nurse in the oil product circulating treatment procedure, has reduced operator's labour intensity; Its structure more can prevent effectively that bubble from producing, and guaranteed the processing quality in the renew cartridge process simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, oil-in 3 of the present utility model and oil return opening 7 all feed in the pending oil product, and oil filler 10 and fuel outlet 9 in the device all are communicated with the extraneous fuel tank that qualified oil product is housed.A closed fuel tank 1 is arranged in the device, filter bed 2 is installed in the closed fuel tank, the filter core in the filter bed can be extracted out from a side of closed fuel tank, so that change.Being used for the oil-in 3 of the pending oil product of inspiration is connected with filter bed oil-in 6 through oil-feed break valve F1, oil pump 4 and heater 5, is used for annotating back that the oil return opening 7 of oil product is connected with filter bed oil-out 8 through oil return break valve F5 after handling.Filter bed oil-out 8 also is connected with fuel outlet 9 by the break valve F6 that drains the oil, and the oil filler 10 that is communicated with extraneous fuel tank is by adding the oil-in that oil cut-off valve F2 is connected to oil pump 4.The fuel tank import 11 of closed fuel tank 1 is connected with filter bed oil-in 6 through break valve F4, the fuel-tank outlet 12 process break valve F3 of closed fuel tank are connected to the oil-in of oil pump 4, and the bleeding point 13 of closed fuel tank is connected with vacuum pump 16 with a gs-oil separator 14 that has observation window 15 through break valve F7.
The course of work of the present utility model is as follows:
One, set-up procedure.The break valve F1 that will interrelate with the external world earlier, F5, F2, F5 closes, and with break valve F3, F4, F7 opens, starting 16 pairs of whole internal duct of vacuum pump then vacuumizes, open break valve F2 subsequently, make qualified oil product in the extraneous fuel tank under negative pressure state, enter and fill internal duct by F2, whole internal duct is filled passes through break valve F7 behind the oil again to gs-oil separator 14 oilings, when oil product reaches observation window 15 positions line, close break valve F2, start oil pump 4, oil product in the internal duct is set out by oil pump 4 at this moment, pass through heater 5 successively, filter bed 2, break valve F4, closed fuel tank 1 and break valve F3, return oil pump 4, make oil product in whole internal duct system, carry out self-loopa, impel the bubble in the oil product to discharge, after observing system does not have bubble from observation window 15, close oil pump 4, vacuum pump 16, break valve F7, F3, F4;
Two, medium decreases the circulating filtration process.After the preparatory stage finishes, open break valve F1 and F5, start oil pump 4, make pending oil product enter system by oil-in 3, pass through break valve F1, oil pump 4, heater 5, filter bed 2, break valve F5 successively, annotate back for 7 mouthfuls by oil return again, realize circulating filtration;
Three, renew cartridge process more.After a period of time, need more renew cartridge at circulating filtration, close break valve F1, F5 this moment, opens break valve F3, F6, starts oil pump 4, and the oil product in the closed fuel tank 1 is drained by fuel outlet, closes break valve F3, F6 again, extracts filter core out and change.After changing and finish, filter core reenters set-up procedure and medium damage circulating filtration process.
