1. Cholinga ndi mawonekedwe athiransifomakukonza
a.Cholinga cha kukonza ma transformer
Cholinga chachikulu cha kukonza kwa thiransifoma ndikuwonetsetsa kuti chosinthira ndi Chalk mkati ndi kunja zigawoamasungidwa m'malo abwino, "oyenera kutero" ndipo amatha kugwira ntchito motetezeka nthawi iliyonse.Chofunika kwambiri ndikusunga mbiri yakale ya chikhalidwe cha transformer.
b.Mafomu okonza ma Transformer
Zosintha zamagetsi zimafunikira ntchito zosiyanasiyana zokonzekera, kuphatikiza kuyeza ndi kuyesa magawo osiyanasiyana a transformer.Pali mitundu iwiri yayikulu yokonza ma transformer.Timapanga gulu limodzi nthawi ndi nthawi (lotchedwa chisamaliro chodzitetezera) ndipo lachiwiri mwapadera (ie, pofuna).
2. Kuwona kwa mwezi uliwonse kwa Periodic Transformer Maintenance
- Mulingo wamafuta mu kapu yamafuta uyenera kuyang'aniridwa mwezi uliwonse kuti usagwere pansi pa malire okhazikika, motero kuwonongeka komwe kumachitika chifukwa chake kumapewedwa.
- Sungani mabowo opumira mu chubu chopumira cha gel osakaniza kuti muwonetsetse kuti mukupuma moyenera.
- Ngati wanuchosinthira mphamvuali ndi tchire lodzaza mafuta, onetsetsani kuti mafutawo adzazidwa bwino.
Ngati ndi kotheka, mafuta adzadzazidwa mu bushing kuti mulingo woyenera.Kudzaza mafuta kumachitika mukamatseka.
3. Tsiku ndi Tsiku Kukonza ndi Kuyang'ana
- Werengani MOG (Maginito Mafuta Meter) ya thanki yaikulu ndi thanki yosungirako.
- Mtundu wa gel osakaniza mu mpweya.
- Mafuta amachoka pamalo aliwonse a thiransifoma.
Pakachitika mafuta osakwanira mu MOG, mafutawo ayenera kudzazidwa mu thiransifoma, ndipo thanki yonse ya thiransifoma iyenera kuyang'aniridwa ngati ikutulutsa mafuta.Ngati mafuta atuluka, chitanipo kanthu kuti mutseke.Ngati gel osakaniza a silika amakhala pinki pang'ono, ayenera kusinthidwa.
4. Ndondomeko yokonza thiransifoma pachaka
- Ntchito yodziyimira payokha, yakutali, komanso yapamanja ya pulogalamu yozizira imatanthawuza kuti mapampu amafuta, mafani a mpweya, ndi zida zina zimalumikizana ndi makina ozizira a transformer ndi dera lowongolera.Adzawunikidwa kwa chaka chimodzi.Zikavuta, fufuzani kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kabwino kake
- Zitsamba zonse za transformer ziyenera kutsukidwa ndi nsalu yofewa ya thonje chaka chilichonse.Pa kuyeretsa bushing ayenera kufufuzidwa ming'alu.
- Mafuta a OLTC aziwunikidwa chaka chilichonse.Chifukwa chake, mafutawo adzatengedwa kuchokera ku valavu yakukhetsa kwa thanki yotsatsira, ndipo mafuta osonkhanitsidwawa adzayesedwa mphamvu ya dielectric (BDV) ndi chinyezi (PPM).Ngati BDV ndi yotsika, ndipo PPM ya chinyezi ndipamwamba kuposa mtengo wovomerezeka, mafuta mkati mwa OLTC amafunika kusinthidwa kapena kusefedwa.
- Kuwunika kwamakina a Buchholzmaulendoziyenera kuchitika chaka chilichonse.
- Zotengera zonse ziyenera kutsukidwa mkati kamodzi pachaka.Magetsi onse, zotenthetsera m'mlengalenga zimafufuzidwa kuti awone ngati zikuyenda bwino.Ngati sichoncho, muyenera kuchitapo kanthu kukonza.Maulumikizidwe onse owongolera ndi ma waya opatsirana amayenera kuyang'aniridwa ngati akulimba kamodzi pachaka.
- Ma relay onse, ma alarm, ndi ma switch owongolera limodzi ndi mabwalo awo, mu R&C (Control Panel and Relays) ndi RTCC (Remote Tap Change Control Panel) ayenera kutsukidwa ndikuyeretsa moyenera.
- Matumba a OTI, WTI (chizindikiro cha kutentha kwamafuta & chizindikiro cha kutentha kwa coil) pachivundikiro chapamwamba cha thiransifoma kuti awonedwe, komanso ngati mafuta akufunika.
- Ntchito yoyenera ya Pressure Release Device ndi Buchholz relay iyenera kuyang'aniridwa pachaka.Chifukwa chake, zida zomwe zili pamwambapa 'zolumikizana ndi ma alamu zimafupikitsidwa ndi kachidutswa kakang'ono ka waya ndikuwona ngati zolumikizirana zomwe zili mugawo lakutali zikugwira ntchito moyenera.
- Kukana kwa thiransifoma ndi polarity index ziyenera kufufuzidwa ndi megger yoyendetsedwa ndi batire ya 5 kV.
- Mtengo wa kukana kwa kugwirizana kwa nthaka ndi rizer ziyenera kuyezedwa chaka ndi chaka ndi chotchinga pa mita yolimbana ndi dziko lapansi.
- Kusanthula kwa DGA kapena kusungunuka kwa gasi wamafuta osinthira thiransifoma kuyenera kuchitidwa chaka chilichonse kwa 132 kV thiransifoma, kamodzi pazaka 2 kwa ma transfoma omwe ali pansi pa 132 kV, kwa zaka ziwiri zosinthira pa thiransifoma ya 132 kV.
Zoyenera kuchita kamodzi pazaka ziwiri zilizonse:
Kuyeza kwa OTI ndi WTI kuyenera kuchitika kamodzi pazaka ziwiri zilizonse.
Tan & delta;Kuyeza kwa thiransifoma bushings kudzachitikanso kamodzi pazaka ziwiri zilizonse
5. Kusintha kwa Transformer pa theka la chaka
Transformer yanu yamagetsi imayenera kuyesedwa miyezi isanu ndi umodzi iliyonse kuti ipeze IFT, DDA, flash point, sludge content, acidity, madzi, mphamvu ya dielectric, ndi kukana kwa mafuta a transformer.
6. KusamaliraTransformer Yamakono
Ma transfoma apano ndi gawo lofunikira pazida zilizonse zomwe zimayikidwa pamalo osinthira magetsi kuti ateteze ndikuyeza magetsi.
The Insulation mphamvu ya CT ziyenera kufufuzidwa chaka chilichonse.Poyesa kukana kwa kutchinjiriza, ziyenera kukumbukiridwa kuti pali magawo awiri otchingira m'ma transformer apano.Mulingo wa kutchinjiriza wa CT yoyamba ndi wokwera kwambiri, chifukwa uyenera kupirira mphamvu yamagetsi.Koma ma CT achiwiri amakhala ndi mulingo wotsikirapo wa 1.1 kV.Chifukwa chake, zoyambira mpaka zachiwiri komanso zoyambira padziko lapansi za zosintha zamakono zimayesedwa mu 2.5 kapena 5 kV meggers.Koma ma voltage megger okwerawa sangathe kugwiritsidwa ntchito poyezera zachiwiri chifukwa mulingo wa insulation ndi wocheperako kuchokera pamawonekedwe azachuma.Chifukwa chake, kutsekemera kwachiwiri kumayesedwa mu 500 V megger.Chifukwa chake, potengerapo pulayimale yopita kudziko lapansi, poyambira poyezera pachimake chachiwiri, ndi poyambira kupita kuchigawo chachiwiri choteteza amayezedwa mu 2.5 kapena 5 kV meggers.
Kusanthula masomphenya a thermo kwa ma terminals ndi dome yapamwamba ya CT yamoyo kuyenera kuchitidwa kamodzi pachaka.Kujambula uku kutha kuchitika mothandizidwa ndi Kamera Yoyang'anira Matenthedwe a Infrared.
Malumikizidwe onse achiwiri a CT mu bokosi lachiwiri la CT ndi bokosi la CT junction ayenera kufufuzidwa, kutsukidwa, ndi kumangirizidwa chaka chilichonse kuti atsimikizire njira yotsika kwambiri ya CT yachiwiri.Komanso, onetsetsani kuti bokosi la CT junction layeretsedwa bwino.
Zogulitsa za MBT Transformer
7. Kusamalira pachaka kwachosinthira magetsis kapena capacitor voteji thiransifoma
Chophimba cha porcelain chiyenera kutsukidwa ndi zovala za thonje.
Msonkhano wa spark gap udzawunikidwa chaka chilichonse.Chotsani gawo losunthika la spark gap posonkhanitsa, yeretsani ma elekitirodi a ma braes ndi sandpaper, ndikuikonzanso m'malo mwake.
Malo oyambira pafupipafupi ayenera kuyang'aniridwa ndi maso chaka chilichonse ngati vutolo silikugwiritsidwa ntchito ku PLCC.
Makamera owonera kutentha amagwiritsidwa ntchito kuyang'ana malo aliwonse otentha m'milu ya capacitor kuti awonetsetse kuti akatswiri akukonza.
Bokosi lolumikizira ma terminal la PT limapangidwa ndi zolumikizira pansi zomwe zimayesedwa kulimba kamodzi pachaka.Kupatula apo, bokosi la PT junction liyeneranso kutsukidwa bwino kamodzi pachaka.
Mkhalidwe wa ziwalo zonse za gasket ziyeneranso kuyang'aniridwa ndi kusinthidwa ngati zisindikizo zowonongeka zapezeka.
