Iziguquli zetephu zizixhobo ezinokonyusa okanye zehlise i-voltage yesibini ephumayo ngokutshintsha umyinge wokujika wokujika okuphambili okanye okwesibini. Umtshintshi wempompo udla ngokufakelwa kwicandelo lombane ophezulu we-transformer enamavili amabini, ngenxa yombane ophantsi kuloo ndawo. Abatshintshi bakwabonelelwa kwi-winding voltage ephezulu ye-transformer yombane ukuba kukho ulawulo olwaneleyo lombane. Ukutshintsha kombane kuchaphazeleka xa utshintsha inani lokujika kwe-transformer enikezelwe ngeetephu.
Kukho iindidi ezimbini zoTshintsho lweTap:
1. On-Layishwa Tap Tjhugulula
Into ephambili yayo kukuba ngexesha lokusebenza, isiphaluka esiphambili sokutshintsha akufanele sivulwe. Oku kuthetha ukuba akukho nxalenye yokutshintsha kufuneka ifumane isiphaluka esifutshane. Ngenxa yokwandiswa kunye noqhagamshelo lwenkqubo yamandla, kuyabaluleka ukutshintsha iimpompo zenguqu izihlandlo ezininzi yonke imihla ukuze kuphunyezwe amandla ombane ayimfuneko ngokwemfuno yomthwalo.
Le mfuno yonikezelo oluqhubekayo ayikuvumeli ukuba uqhawule uqhagamshelo lwesiguquli kwinkqubo yokutshintsha impompo yomthwalo. Ke ngoko, abaguquli bempompo ekulayishweni bakhethwa kuninzi lwabaguquli bamandla.
Iimeko ezimbini kufuneka zizaliseke ngelixa ucofa:
·Isekethe yomthwalo kufuneka isebenze ukuphepha i-arcing kunye nokuthintela umonakalo woqhagamshelwano
·Ngelixa ulungisa impompo, akukho nxalenye yee-windings kufuneka ibe mfutshane-circuited
Kulo mzobo ungentla, u-S yi-diverter switch, kunye no-1, 2 kunye no-3 ngabakhethi bokutshintsha. Ukutshintsha impompo kusebenzisa ireactor ecofiweyo esembindini njengoko kubonisiwe kwidayagram. I-transformer isebenza xa utshintsho lwe-1 kunye ne-S luvaliwe.
Ukutshintshela kwitephu yesi-2, iswitshi S kufuneka ivulwe kwaye iswitshi yesi-2 kufuneka ivalwe. Ukugqibezela utshintsho lwempompo, iswitshi 1 iyasebenza kwaye iswitshi S ivaliwe. Khumbula ukuba i-diverter switch isebenza kumthwalo kwaye akukho nto ihamba ngoku kumkhethi wokutshintsha ngexesha lokutshintsha impompo. Xa ucofa utshintsho, kuphela isiqingatha sokuphendula esinqanda okwangoku sidityaniswe kwisekethe.
2.Off-Load/No-load Tap Changer
Kufuneka ufake i-off-load change kwi-transformer ukuba utshintsho olufunekayo kwi-voltage aluqhelekanga. Iimpompo zingatshintshwa emva kokuhlukanisa ngokupheleleyo i-transformer kwisekethe. Olu hlobo lotshintsho lufakwe ngokubanzi kwi-transformer yokusabalalisa.
Ukutshintsha impompo kunokuqhutywa xa i-transformer ikwi-Off-Load okanye i-No-Load condition. Kwi-transformer yohlobo olomileyo, i-phenomenon yokupholisa iyenzeka ikakhulu ngomoya wendalo. Ngokungafaniyo nokutshintsha impompo yomthwalo apho ukucima i-arc kunqunyanyiswa yi-oyile xa i-transformer ilayishiwe, ukucofa kunye ne-off-load tap changer iqhutyelwa kuphela xa i-transformer ikwimeko ye-OFF-Switch.
Ihlala isetyenziswa kwiimeko apho umyinge wokujika kungafuneki utshintshwe kakhulu, kwaye ukucima amandla kuvunyelwe kumandla aphantsi kunye neziguquli zombane ophantsi. Kwezinye, ukutshintsha impompo kunokwenziwa ngerotary okanye iswitshi yesilayidi. Inokubonwa ikakhulu kwiiprojekthi zamandla elanga.
Iziguquli zetephu ezingasebenziyo zikwasetyenziswa kwiinguqu zamandla ombane aphezulu. Inkqubo yezo ziguquli zibandakanya umtshini wempompo ongenamthwalo kwi-winding ephambili. Olu tshintsho lunceda ukwamkela iiyantlukwano ngaphakathi kwebhanti emxinwa malunga nokulinganisa okuqhelekileyo. Kwiinkqubo ezinjalo, ukutshintsha impompo kuya kwenziwa kube kanye kuphela, ngexesha lofakelo. Nangona kunjalo, inokutshintshwa ngexesha lokucima okucwangcisiweyo ukulungisa naluphi na utshintsho lwexesha elide kwiprofayili yombane wenkqubo.
Kunyanzelekile ukuba ukhethe uhlobo oluchanekileyo lokutshintsha impompo ngokusekelwe kwiimfuno zakho.
