1. Chinangwa uye mafomu etransformerkuchengetedza
a.Chinangwa chekugadzirisa transformer
Chinangwa chekutanga chekugadzirisa shanduko ndechekuona kuti iyo transformer uye accessories 'mukati nekunze zvikamuanochengetwa ari muchimiro chakanaka, “akakodzera chinangwa” uye anogona kushanda akachengeteka chero nguva.Zvakaenzana zvakakosha kuchengetedza nhoroondo yezvakaitika zve transformer mamiriro.
b.Transformer kugadzirisa mafomu
Magetsi emagetsi anoda akasiyana-siyana ekugadzirisa mabasa echinyakare, anosanganisira kuyera uye kuyedza akasiyana maparameter.Kune maviri ekutanga mafomu ekugadzirisa transformer.Isu tinoita boka rimwechete nguva nenguva (inonzi kudzivirira kuchengetedza) uye yechipiri pane yakasarudzika (kureva, pane-inoda).
2. Monthly Periodic Transformer Maintenance Check
- Nhamba yemafuta muvharo yemafuta inofanira kuongororwa mwedzi wega wega kuti irege kuwira pasi pemuganhu wakatarwa, uye nokudaro kukanganisa kunokonzerwa nayo kunodziviswa.
- Chengetedza maburi ekufema mu silica gel yekufema chubhu yakachena kuti uve nechokwadi chekushanda kwekufema.
- Kana yakosimba transformerine mafuta anozadza makwenzi, ita shuwa kuti mafuta akazadzwa nemazvo.
Kana zvichidikanwa, mafuta anozadzwa mubhushi kusvika padanho rakakodzera.Kuzadza mafuta kunoitwa mumamiriro ekudzima.
3. Daily Basis Maintenance uye Kutarisa
- Verenga iyo MOG (Magnetic Oiri Meter) yetangi huru uye tangi yekuchengetedza.
- Ruvara rwesilica gel mukufema.
-Oiri inodonha kubva kune chero nzvimbo ye transformer.
Muchiitiko chekusagutsikana kwemafuta muMOG, mafuta anofanirwa kuzadzwa mushanduko, uye tangi rose rekushandura rinofanira kuongororwa kuti rinodonha mafuta.Kana mafuta akabuda akawanikwa, tora chiito chinodiwa kuti uvhare kubuda.Kana iyo silica gel ikava pink zvishoma, inofanira kutsiviwa.
4. Basic gore negore transformer kugadzirisa purogiramu
-Iyo otomatiki, iri kure, uye yemanyorero basa reinotonhora system zvinoreva kuti pombi dzemafuta, mafeni emhepo, uye zvimwe midziyo inojoinha iyo inoshandura kutonhora sisitimu uye dunhu rekutonga.Vachaongororwa kwenhambo yegore rimwe.Muchiitiko chekusashanda, ongorora dunhu rekutonga uye mamiriro emuviri wepombi uye fan.
- Yese mabhuni emagetsi anofanirwa kucheneswa nemucheka munyoro wedonje gore negore.Panguva yekucheneswa kwebhushi kunofanira kuongororwa kune kuputika.
-Mamiriro emafuta eOLTC anozoongororwa gore negore.Naizvozvo, sampu yemafuta inotorwa kubva kudhivhavha yedhivhavha yetangi inosiya, uye iyi yakaunganidzwa sampu yemafuta inozoongororwa simba re dielectric (BDV) uye humidity (PPM).Kana iyo BDV yakadzikira, uye iyo PPM yekunyorova yakakwira kupfuura kukosha kwakakurudzirwa, mafuta ari mukati meOLTC anoda kutsiviwa kana kusefa.
- Mechanical kuongororwa kweBuchholzrelayszvinofanira kuitwa gore negore.
- Magaba ese anofanira kucheneswa kubva mukati kanenge kamwe pagore.Magetsi ese, maheater emuchadenga anotariswa kuona kana ari kushanda nemazvo.Kana zvisina kudaro, unofanira kutora matanho ekugadzirisa.Ese materminal anongedzo ekudzora uye relay wiring kuti atariswe akasimba kanenge kamwe pagore.
- Yese marelay, maaramu, uye kudzora switch pamwe chete nemaseketi avo, muR&C (Control Panel uye Relays) uye RTCC (Remote Tap Change Control Panel) mapaneru, anofanirwa kucheneswa nekuchenesa zvinhu.
-Mahomwe eOTI, WTI (Oiri tembiricha chiratidzo & coil tembiricha chiratidzo) pane chekushandura chivharo chepamusoro kuti chitariswe, uye kana mafuta achidiwa.
-Iyo basa rakakodzera rePressure Release Device uye Buchholz relay inofanira kuongororwa gore negore.Naizvozvo, zvigadziriso zviri pamusoro 'mafambiro ekufambisa uye maaramu ekubatika anopfupikiswa nechidimbu chewaya uye tarisa kana iwo anoenderana relay mune ari kure control panel ari kushanda nemazvo.
- The transformer's insulation resistance uye polarity index ichaongororwa ne megger inoshandiswa ne 5 kV bhatiri.
-Kukosha kwekupikisa kwepasi uye rizer inofanira kuyerwa gore negore nechibatiso pamita yekupikisa pasi.
- DGA kana kunyungudika gasi kuongororwa kwemafuta ekushandura kunofanira kuitwa gore negore kune 132 kV transformers, kamwe chete mumakore maviri kune vashanduri pasi pe132 kV, kwemakore maviri kune vashanduri pane 132 kV transformer.
Chiito chinofanira kuitwa kamwe chete makore maviri ega ega:
Iyo OTI uye WTI calibration inofanirwa kuitwa kamwe chete makore maviri ega ega.
Tan & delta;Iyo kuyerwa kweiyo transformer bushings ichaitwa zvakare kamwe chete makore maviri
5. Transformer kugadzirisa kwehafu yegore
Simba rako rinoshandura rinoda kuongororwa mwedzi mitanhatu yega yega yeIFT, DDA, flash point, sludge content, acidity, mvura yemukati, dielectric simba, uye transformer mafuta kuramba.
6. KuchengetedzaCurrent Transformer
Azvino ma transformer chikamu chakakosha chechero mudziyo wakaiswa mumagetsi emagetsi chiteshi kuchengetedza uye kuyera magetsi.
Iyo insulation simba re CT inofanira kuongororwa gore negore.Muchiito chekuyera kudzivirira kwekudzivirira, inofanira kuyeukwa kuti kune maviri ekudzivirira mazinga mumashanduri azvino.Iyo insulation level yeprimary CT yakakwira zvakanyanya, sezvo ichifanirwa kumirisana neiyo system voltage.Asi yechipiri CT's ine yakaderera insulation level muhuwandu hwe1.1 kV.Naizvozvo, yekutanga kune yechipiri uye yekutanga kune pasi yezvino transformer inoyerwa mu 2.5 kana 5 kV meggers.Asi iyi yakakwira voltage megger haigone kushandiswa kune yechipiri kuyerwa sezvo iyo insulation level yakadzikira kubva kune dhizaini yehupfumi maonero.Naizvozvo, iyo yechipiri insulation inoyerwa mu500 V megger.Saka, iyo yekutanga terminal yepasi, yekutanga terminal kune yechipiri yekuyera core, uye yekutanga terminal kune inodzivirira yechipiri core inoyerwa mu2.5 kana 5 kV meggers.
Thermo chiono chekuongorora chepuraimari terminals uye yepamusoro dome ye CT mhenyu inofanira kuitwa kamwechete pagore.Iyi scan inogona kuitwa nerubatsiro rweInfrared Thermal Surveillance Camera.
Yese CT yechipiri yekubatanidza muCT yechipiri bhokisi uye CT junction bhokisi inofanirwa kutariswa, kucheneswa, uye kusimbiswa gore negore kuti ive nechokwadi yakaderera inobvira CT yechipiri kuramba nzira.Zvakare, ita shuwa kuti iyo CT junction bhokisi inocheneswa nemazvo.

7. Kuchengetwa kwegore negore kwevoltage transformers kana capacitor voltage transformers
Chifukidzo cheporcelain chinofanira kucheneswa nezvipfeko zvekotoni.
Iyo spark gap assembly ichaongororwa gore negore.Bvisa chikamu chinofambiswa che spark gap paunenge uchiunganidza, chenesa mabraes electrode ne sandpaper, uye gadzirisa zvakare panzvimbo.
High-frequency grounding point inofanirwa kutariswa nemaziso gore rega rega kana nyaya ikasashandiswa kuPLCC.
Makamera ekuona anopisa anoshandiswa kutarisa chero nzvimbo dzinopisa mu capacitor stacks kuti ive nechokwadi chekugadzirisa chiitiko.
Terminal yekubatanidza PT junction bhokisi rine pasi pekubatanidza kwakaedzwa kusimba kamwe chete pagore.Kunze kwezvo, iyo PT junction bhokisi inofanirwawo kucheneswa zvakanaka kamwe pagore.
Mamiriro emajoini ese egasket anofanirwawo kutariswa nekuona uye kutsiviwa kana zvisimbiso zvakakuvadzwa zvakawanikwa.
