Ga wasu Zaman Da Yana Daidaita Masana'antu?

1. Zama na Gargajiya na Maimakon Transformer

• Yana da kyau a yi nufin maimakon mai gari-gari na transformer kafin a yi amfani da shi, kuma ya kamata a yi maimakon mai gari-gari har shekaru 5 zuwa 10 bayan. Idan yake fitowa a lokacin da ake amfani da shi ko idan an samu matsalolin da ba a tabbatar a cikin testun da ake yi a baya, ya kamata a yi maimakon mai gari-gari.

• Transformers masu amfani da shi tsohon lokaci da kadan zai iya a yi maimakon har shekara 10.

• Idan a yi amfani da transformers masu tap changer a lokacin da ake amfani da shi, ya kamata a ci gaba irin yanayin da ake bayarwa a kan mekanismi na tap changer.

• Transformers da ake fadada a wurare da suka mutuwar da sauran abubuwan da suka mutu, ya kamata a yi nasarun zama na maimakonta kamar yadda ake samu tushen amfani, bayanan testi, da kuma takardun fanni.

2. Tushen da Abubuwan da za a Yi a Maimakon Mai Gari-Gari na Transformer

• Tashin da za a yi kafin maimakon: Duba da samun cututtuka daga takarda ta amfani, tabbatar da su a kan maye, da kuma faɗa masana'antu don gyaran. Idan cututtukan da ke da muhimmanci domin haka, ya kamata a yi masana'antu masu hanyar da damar tushen da damar jami'a. Faɗa jerin kayan aiki, abincin, da kuma alamomin da za a buƙata, da kuma duba kan maye a kan maimakon don tabbatar da duka abubuwan da ke da muhimmanci da kuma yanayin da ke da muhimmanci.

• Sauki na taili, kawo karamin transformer, koyi mai gari-gari, da kuma nufin windings da mai gari-gari.

• Maimakon mai gari-gari, windings, tap changer, da kuma lead wires.

• Maimakon karamin transformer, conservator tank, explosion-proof pipe, radiators, oil valves, breather, da kuma bushings.

• Maimakon cooling system da oil reclamation unit.

• Hafi tank shell, da kuma rufo idan yana da kyau.

• Maimakon kontrol, measuring instruments, signaling, da kuma protective devices.

• Filter ko kawo insulating oil.

• Dry the insulation idan yana da kyau.

• Rabta transformer.

• Yi measurements da tests kamar yadda ake dogara a kan test procedures.

• Bayan a dole da duk tests, karkashin transformer a amfani.

3. Tsarin da Abubuwan da za a Yi a Maimakon Mai Gari-Gari na Transformer

• Don in hada inganta cututtuka masu mai gari-gari saboda gasar da suka girma, ya kamata a rage maimakon mai gari-gari a ranar yaki ko rana gaske. Yawancin lokacin da ake da muhimmanci a kan maimakon mai gari-gari a kan air shine:

• A kan air mai gaske (relative humidity ≤65%): 16 hours

• A kan air mai gaske (relative humidity ≤75%): 12 hours
  Kafin maimakon mai gari-gari, kara temperature na canza da kuma temperature na transformer oil. Maimakon mai gari-gari zai iya faru bayan mai gari-gari yana da temperature da yake 10°C fiye da temperature na canza.

• Idan a yi amfani da transformers masu tsakanin shekaru 20, ya kamata a yi nuna cututtuka masu mai gari-gari a kan winding insulation aging. A gaba daya, wannan ana yi ne tare da finger:

• Insulation mai kyau yana da kyau, yana da karfin da yake da kyau, yana kusa da finger pressure kuma yana da kyau bayan a kawo, da kuma surface mai kyau.

• Insulation mai yawa yana da kyau, yana da karfin da yake da kyau, finger pressure yana kasa small cracks kuma yana da color mai yawa. A cikin haka, ya kamata a kawo ko kuma a gyara insulation.

• Insulation mai yawa daidai yana kasa da finger pressure kuma yana kawo carbonized particles, ya kamata a kawo insulation daidai.

• Insulating spacers a kan winding transformers ya kamata a zama da kyau; windings ba zai da lallace, deformation, ko displacement. High- da low-voltage windings ya kamata a zama symmetrical da kuma da kyau, ba zai da oil-adhered contaminants.

• Tap changer contacts ya kamata a zama da kyau; insulating pressboard da insulating tubing ya kamata a zama intact da kuma da kyau.

• Tabbatar da contact positions, tightening screws, rotating shafts, da kuma markings a kan voltage selector switch suka zama da kyau da labels a kan cover.

• Core ba zai da lallace; oil ducts (cooling channels) a kan core da windings ya kamata a zama unobstructed.

• Kara insulation resistance of core-through bolts ta 1000 V megohmmeter. Minimum acceptable values shine:

• ≥2 MΩ for 3 kV, 6 kV, and 10 kV transformers

• ≥5 MΩ for 35 kV transformers

• Insulation resistance of the secondary circuit of the Buchholz relay ya kamata a zama da kyau, wiring ya kamata a zama da kyau, da kuma internal float da mercury contacts ya kamata a zama intact.

• Yadda mai shirya da kwalba yana cikin kwalba masu zuba zai ci gaba a fili na musamman.
