1. Chinangwa uye mafomu etransformerkugadzirisa
a. Chinangwa chekugadzirisa transformer
Chinangwa chikuru chekugadzirisa transformer ndechekuona kuti transformer nezvimwe zvinhu zvemukati nekunze zvikamudzinochengetwa dziri mumamiriro akanaka, "dzakakodzera chinangwa ichi" uye dzinogona kushanda zvakachengeteka chero nguva. Zvakakoshawo kuchengetedza nhoroondo yemamiriro etransformer.
b. Mafomu ekugadzirisa matransformer
Matransformer emagetsi anoda mabasa akasiyana-siyana ekugadzirisa nguva dzose, anosanganisira kuyera nekuyedza maparamita akasiyana etransformer. Kune marudzi maviri makuru ekugadzirisa matransformer. Tinoita boka rimwe nguva nenguva (rinonzi preventive maintenance) uye rechipiri panguva imwe chete (kureva, kana richidiwa).
2. Kuongorora Kwekugadzirisa Transformer Kwemwedzi Nemwedzi
– Huwandu hwemafuta muchikamu chemafuta hunofanira kuongororwa mwedzi wega wega kuitira kuti husawire pasi pemuganhu wakatarwa, uye nokudaro kukuvara kunokonzerwa nawo hakuzodzivirirwi.
- Chengeta maburi ekufema ari muchubhu yekufema ye silica gel akachena kuti uve nechokwadi chekuti kufema kwacho kwashanda zvakanaka.
- Kana yakotransformer yemagetsiine makwenzi anozadza mafuta, iva nechokwadi chekuti mafuta azere nemazvo.
Kana zvichidikanwa, mafuta anozadzwa mubushing kusvika padanho rakakodzera. Kuzadzwa kwemafuta kunoitwa mumamiriro ekudzima.
3. Kugadzirisa uye Kutarisa Zuva Nezuva
– Verenga MOG (Magnetic Oil Meter) yetangi guru netangi rekuchengetera zvinhu.
- Ruvara rwesilica gel iri mumhepo.
- Oiri inodonha kubva chero kupi zvako kwetransformer.
Kana mafuta asina kuzara muMOG, mafuta acho anofanira kuzadzwa mutransformer, uye tangi rese retransformer rinofanira kuongororwa kuti harina mafuta here. Kana mafuta akawanikwa, tora matanho anodiwa kuti uvhare mafuta acho. Kana silica gel ikashanduka kuita pink zvishoma, inofanira kutsiviwa.
4. Purogiramu yegore negore yekugadzirisa transformer
– Basa re otomatiki, rekure, uye remaoko resystem yekutonhodza zvinoreva kuti mapombi emafuta, mafeni emhepo, nezvimwe zvishandiso zvinobatana nesystem yekutonhodza yetransformer necircuit yekudzora. Izvi zvichaongororwa kwenguva yegore rimwe chete. Kana zvikasashanda zvakanaka, ongorora circuit yekudzora uye mamiriro epombi nefeni.
- Mabushing ese etransformer anofanira kucheneswa nejira redonje rakapfava gore rega rega. Panguva yekuchenesa bushing, tarisa kana paine mitswe.
- Mamiriro emafuta eOLTC achaongororwa gore rega rega. Nokudaro, sampuro yemafuta ichatorwa kubva muvharuvhu yekudhonza yetangi rinopatsanura, uye sampuro iyi yemafuta yakaunganidzwa ichaongororwa simba re dielectric (BDV) nehunyoro (PPM). Kana BDV yakaderera, uye PPM yehunyoro yakakwira kupfuura kukosha kunokurudzirwa, mafuta ari mukati meOLTC anofanira kutsiviwa kana kuseferwa.
- Kuongororwa kweBuchholz nemechanicalmarelaykuitirwa gore rega rega.
- Matangi ese anofanira kucheneswa kubva mukati kanenge kamwe chete pagore. Mwenje yese, maheater anotariswa kuti aonekwe kana ari kushanda nemazvo. Kana zvisina kudaro, unofanira kutora matanho ekugadzirisa. Ma terminal connections ese e control ne relay wiring anofanira kuongororwa kanenge kamwe chete pagore.
- Ma relay ese, ma alarm, uye ma control switch pamwe chete nema circuits avo, muma R&C (Control Panel and Relays) uye ma RTCC (Remote Tap Change Control Panel), anofanira kucheneswa nekuchenesa kwakakodzera.
- Homwe dzeOTI, WTI (Oil temperature indicator & coil temperature indicator) dziri pamusoro pe transformer dzinofanira kuongororwa, uye kana mafuta achidiwa.
- Basa rakakodzera rePressure Release Device neBuchholz relay rinofanira kuongororwa gore rega rega. Nokudaro, ma trip contacts emidziyo iri pamusoro apa uye alarm contacts dzinopfupikiswa newaya diki uye tarisa kana ma relay ane chekuita neaya ari mu remote control panel ari kushanda nemazvo.
- Kudzivirira kupinza kwetransformer uye polarity index zvinofanira kuongororwa ne megger inoshanda nebhatiri re5 kV.
- Kukosha kwekudzivirira kwekubatana kwepasi pamwe nerizer zvinofanirwa kuyerwa gore rega rega nechinhu chinosunga pamita yekudzivirira pasi.
- Kuongororwa kwemafuta etransformer neDGA kana gasi rakanyungudutswa kunofanirwa kuitwa gore rega rega kune matransformer e132 kV, kamwe chete mumakore maviri kune matransformer ari pasi pe132 kV, kwemakore maviri kune matransformer ari patransformer ye132 kV.
Matanho ekutorwa kamwe chete mumakore maviri ega ega:
Kuongororwa kweOTI neWTI kunofanirwa kuitwa kamwe chete mumakore maviri ega ega.
Tan & delta; Kuyerwa kwemabhandi etransformer kunofanirawo kuitwa kamwe chete mumakore maviri ega ega
5. Kugadziriswa kwetransformer kwehafu yegore
Transformer yako yemagetsi inofanira kuongororwa mwedzi mitanhatu yega yega kuti ione kana ine IFT, DDA, flash point, sludge content, acidity, water content, dielectric strength, uye transformer oil resistance.
6. Kugadziriswa kweTransformer Yazvino
Matransformer aripo iye zvino chikamu chakakosha chemidziyo chero ipi zvayo yakaiswa muchiteshi chetransformer chemagetsi kuchengetedza nekuyera magetsi.
Simba rekudzivirira re CT inofanira kuongororwa gore rega rega. Mukuita kwekuyera kusimba kwekudzivirira kupisa, zvinofanira kurangarirwa kuti kune mazinga maviri ekudzivirira kupisa mumatransformer emagetsi. Kudzivirira kupisa kweCT yekutanga kwakakwira, sezvo kuchifanira kutsungirira voltage yesystem. Asi maCT echipiri ane mazinga ekudzivirira akaderera e1.1 kV. Saka, matransformer epakutanga kusvika kusekondari uye ekutanga kusvika pasi anoyerwa mu 2.5 kana 5 kV meggers. Asi iyi high voltage megger haigone kushandiswa pakuyera kwechipiri sezvo mazinga ekudzivirira kupisa akaderera kubva pamaonero ehupfumi hwedhizaini. Saka, secondary insulation inoyerwa mu 500 V megger. Saka, primary terminal kuenda pasi, primary terminal kuenda kusecondary measuring core, uye primary terminal kuenda kusecondary core inodzivirira inoyerwa mu 2.5 kana 5 kV meggers.
Kuongororwa kweThermo vision kwezvikamu zvekutanga uye dome repamusoro reCT live kunofanirwa kuitwa kanenge kamwe chete pagore. Kuongororwa uku kunogona kuitwa nerubatsiro rweInfrared Thermal Surveillance Camera.
Zvese zvinobatanidzwa zveCT secondary muCT secondary box neCT junction box zvinofanirwa kuongororwa, kucheneswa, uye kusimbiswa gore rega rega kuitira kuti pave nechokwadi chekuti nzira yeCT secondary resistance yakaderera. Uyewo, iva nechokwadi chekuti CT junction box yacheneswa nemazvo.
Zvigadzirwa zveMBT Transformer
7. Kugadziriswa kwegore negore kwetransformer yemagetsis kana kuti capacitor voltage transformers
Chifukidziro cheporcelain chinofanira kucheneswa nembatya dzedonje.
Kuungana kwenzvimbo inotsvedza kuchaongororwa gore rega rega. Bvisa chikamu chinofambiswa chenzvimbo inotsvedza paunenge uchibatanidza, chenesa electrode yebraes nesandpaper, woigadzirisa panzvimbo yayo.
Nzvimbo yekumisa pasi ine mafrequency akawanda inofanira kuongororwa nemaziso gore rega rega kana dambudziko racho rikasashandiswa paPLCC.
Makamera ekuona kupisa anoshandiswa kutarisa chero nzvimbo dzinopisa dziri muma capacitor stacks kuti ave nechokwadi chekuti nyanzvi dzinogadzirisa.
Bhokisi rePT junction rine madziro epasi akaedzwa kuti aonekwe kuti akasimba here kamwe chete pagore. Pamusoro pezvo, bhokisi rePT junction rinofanirawo kucheneswa zvakanaka kamwe chete pagore.
Mamiriro emajoini ese egasket anofanirawo kuongororwa nemaziso uye kutsiviwa kana zvisimbiso zvakakuvara zvikawanikwa.
