Idan MOG (presumably a specific component) ya da locking lever, koye shi. Samun conservator. A cikin on - load tap changer (OLTC), conservatorin ta ya kamata a samu daɗi abin daɗi a cikin conservator na ɗaya, ko kuma daɗi abin daɗi a cikin main conservator. Idan conservatorin OLTC ya kamata a samu daɗi abin daɗi, ya kamata a samu shi.
Samun conservator a cikin General Arrangement (G.A.) drawing. Duk da yake, small conservator for the on - load tap changer ya kamata a samu a cikin main conservator.
Samun connecting pipe with Buchholz relay daga main tank zuwa conservator. Duba cewa Buchholz relay ya faru da kyau, da arrow ake ya nuna zuwa conservator.
Samun breather connecting pipes da silica gel breathers don main tank da OLTC conservators.
A cikin samun flexi separator (air cell) a cikin conservator, ana iya duba hakan da aka bayyana: (Specific installation steps can be added here according to the actual content. Since no relevant content is provided in the original text, it can be further improved if there is relevant content later.)
Samun air cell a cikin conservator. Duba cewa hooks a cikin air cell ya kama da kyau a cikin brackets a cikin conservator.
Bincika cewa babu leakages da kuma tabbacin cewa babu.
Conservator with the air cell an yi pressure - tested a factory da kuma an samu shi da slight positive pressure. Duba cewa babu oil leakage.
Samun three air - release valves a cikin conservator.
Buka air - release valves. Gara air - filling adapter zuwa breather pipe da kuma karamin air cell zuwa air pressure da ake nuna a instruction plate affixed to the transformer. Daya da wannan air pressure.
Buka air - release valves da kuma bincika oil filling daga bottom filter valve of the transformer.
Bincika air - release valves. Idan oil ya faru, koye air - release valves one by one. Koye oil filling idan duk air - release valves an kama.
Koye air - filling adapter.
Dare oil filling da kuma bincika Magnetic Oil Level Gauge (MOLG).
Koye filling idan needle of the MOLG ya kama zuwa level corresponding to the ambient temperature during filling.
Samun silica - gel breather.
Babu da zan iya buka air - release valves ba bayan an kama oil filling. Idan an buka air - release valve, air zai zama da kuma oil level zai rage.
Ordinary oil - level gauge a end - cover of the conservator ya kamata a nuna full oil level.
Idan air ya zama a cikin conservator, drop in the oil level on the ordinary oil - level gauge zai nuna shi.
Bincika ordinary oil - level gauge da kyau.
A cikin separator, conservator ya kamata a samu da kuma connected above the transformer, da kuma lower part ya kamata a samu da oil - filling reserve via a pipe. Dare hakan:
Create a vacuum inside the separator.
Using the same vacuum source, create a vacuum in the conservator.
Buka oil - filling valve of the transformer. Saboda vacuum in the conservator, oil level zai faru automatically.
Koye oil filling idan required volume an kama a cikin conservator.
While maintaining the vacuum in the conservator, allow dry air or nitrogen gas to enter the interior of the separator. The separator zai karamin shi da kyau da kuma occupy the free space, as the conservator is not completely full. During operation, in particular, the oil will rise to the top of the conservator.
Karamin separator zuwa maximum level indicated on the instruction plate.
Bincika vent holes da kuma tabbacin cewa babu residual air in the conservator. Adjust the oil level if necessary.
Floats of the Buchholz relay an kaɓe don hanyar transport don bincike damage. Su kan basu. Kuma, idan 'Test' lever ya kamata, ya kamata a set zuwa working position.
Idan On - Load Tap Changer (OLTC) ya kamata, ya kamata a samu da its own separate breather.
Bincika cewa color of the silica gel in the main breather ya blue.
Koye rubber cap that closes the breather pipe and the breather.
Fill oil in the oil cup and remove the seal that closes the breather opening.
Similarly, install the OLTC breather.
Radiators ya kamata a samun one at a time. Oil required to fill the radiators an samu separately in drums. Test an oil sample from each drum for Breakdown Voltage (BDV). Duba cewa it exceeds the minimum value specified in Indian Standard (I.S.) 1866 for new transformers.
Idan oil filter machine ya kamata, amfani da shi don fill the conservator completely with oil.
Kare exterior of one radiator. Koye blanking plates da kuma kare gaskets and radiator flanges. Idan gaskets an damsa, koyar da spare gaskets.
Idan blanking plates ba su kaɓe, da kuma ana shiga rayuwar da ke gano, kare interiors su by flushing with fresh and clean transformer oil.
Oil may seep through the tank - side radiator valves and be retained by the blanking plates. This oil should be collected in a clean container when removing the top and bottom blanking plates.
Align the radiator flanges with those on the tank. Duba cewa tank gasket ya cika. Fasten them with bolts, nuts, spring washers, etc.
Use the operating handle to open the bottom radiator valve. Gradually unscrew the air - release plug on top of the radiator until air starts to escape.
Do not fully remove the air - release plug from its threads, as it will be difficult to control the oil flow. Close the air - release plug when oil flows steadily from it and no more air comes out.
Open the top radiator valve. The oil level in the conservator will now have dropped. Bincika cewa babu oil leakage from the radiator itself and the gasket joints.
Restore the oil level and assemble the next radiator in the same manner.
