± 800KV DC converter transformer, the transformer oil total amount is 120m3 approximately, adopts two tank circulating filtrations, single circulating tank volume 15m3, coefficient 80% approximately needs 10 tanks oil, concrete processing method:
(1) equipment circulation flushing
New oil filter is first to be used or more behind the renew cartridge, need to carry out circulation flushing to oil filter.Two oil tanks are connected respectively to A interface and the B interface of oil filter, fill oil in the A tank, the B tank is slack tank.At first start shooting at the A tank: open the first inlet valve 1, interior circulating valve 5 cuts out other valve, starts canned pump 8; Open one-level vent valve 23,24, three grades of vent valves 25 of secondary exhaust valve and level Four vent valve 26 carry out exhaust, and exhaust finishes to close corresponding vent valve; Regulate pump discharge adjuster valve 9, making flowmeter 10 readings is 12m3/h, and the oil filter system is carried out circulation flushing, washing time approximately 24 hours;
(2) tank internal circulation filtering (need filter 23 all over)
From outlet sample valve 17 sample analysis granule numbers, defective continuation circulation, qualified after, open the first bleeder valve 3, close interior circulating valve 5, filter from the A tank to the B tank; After about 1 hour, the A tank has filtered, and opens interior circulating valve 5, closes the first bleeder valve 3 and the first inlet valve 1, opens the second inlet valve 2 and the second bleeder valve 4, closes interior circulating valve 5, begins to filter from the B tank to the A tank; So repeatedly, filter 23 time; Respectively from charging sample valve 6 and discharging sample valve 17 sample analysis granule numbers, after two samples are all qualified, filter and finish to shut down;
(3) transformer oil filling
Annotate to transformer (by other Special Equipment) filtering good oil.Again give A tank perfusion fresh oil, begin the second tank and filter, need altogether 10 tanks;
(4) body-internal-circulation is filtered
After oil is filled it up with in the transformer, need to continue circulating filtration to the oil in the transformer.Oil filter A, B interface all are connected to transformer, and start is carried out circulating filtration to the oil that is filled in the transformer shell, to remove the impurity such as dust that produce in the installation process again.Filtration time needs 7~10 days, finally from charging sample valve 6 and discharging sample valve 17 sample analysis granule numbers, after two samples are all qualified, filter and finishes to shut down.Whole end-of-job.
Granule number greater than 5 μ m among the initial crude oil 100mL is 7000, filter 23 all over after, granule number greater than 5 μ m in the 100mL oil is 350, reaches primary standard in the NAS1638 standard (super cleaning systems, in the 100mL oil greater than the granule number scope of 5 μ m at 250~500).
Specific implementation approach of the present utility model and mode also have a lot, and the above only is a kind of embodiment of the present utility model.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model basic principle, also can make some improvement and modification, these improvement and modification also should be considered as protection range of the present utility model.
