Njengomenzi wezixhobo zamandla oqeqeshiweyo,Amandla Anqianginikeza ethembekileyoZero Ulandelelwano Umguquleli wangokueyenzelwe ukufumanisa intsalela yangoku kunye nokuxhasa ukukhuselwa kwempazamo yomhlaba kwiinkqubo zokuhambisa amandla. Ulwakhiwo lwayo lwe-split-core, ukusebenza kwamagnetic okuzinzile, kunye nofakelo olufanelekileyo luyenza ilungele ukhuseleko kunye nokubeka iliso kwizicelo apho ukufumanisa impazamo ngokukhawuleza kunye nokusebenza okuthembekileyo kubalulekile.
I-Zero Sequence Current Transformer yi-transformer yangoku ekhethekileyo esetyenziselwa ukufumanisa intsalela okanye i-zero-sequence current ebangelwa ukungalingani kwangoku kunye neziphene zomhlaba. Ngokungafaniyo nabaguquli bangoku abaqhelekileyo abalinganisa ngokuyintloko imisinga yesigaba somntu ngamnye, esi sixhobo sibeka iliso kwi-current edibeneyo edlula kwi-core transformer. Ngaphantsi kweemeko eziqhelekileyo zokusebenza, i-vector sum of currents esweni isondele kwi-zero. Xa impazamo yomhlaba okanye indlela yokuvuza isenzeka, ibhalansi iyatshintsha kwaye intsalela yangoku ifunyenwe. Lo mqondiso unokugqithiselwa kwi-relay yokukhusela ukuqalisa isenzo esifanelekileyo sokukhusela.
Uthungelwano lokusasazwa kwemizi-mveliso, izitishi, iindibano ze-switchgear, kunye neeprojekthi ze-retrofit, ukukhetha i-transformer efanelekileyo kufuna ingqalelo kuyilo olungundoqo, ubungakanani be-aperture, i-insulation, indlela yofakelo, ukuchaneka, ukuhambelana kwe-relay, kunye neemeko zokusingqongileyo. I-Zero ekhethiweyo ngokufanelekileyo iSequence Current Transformer inokuphucula ukubeka iliso kwimpazamo ngelixa inceda iinkqubo zokukhusela ziphendule ngokufanelekileyo.

IiNgcaciso zeMveliso kunye neNgcaciso yoKhetho
I-Zero Sequence Current Transformer, edla ngokubizwa ngokuba yi-core-balance current transformer okanye i-residual current transformer, yenzelwe ukufumanisa ukungalingani kwangoku ngaphakathi kwesekethe yombane. Ukusetyenziswa kwayo okuphambili kukuchonga intsalela yangoku ehambelana neziphene zomhlaba, iingxaki zokugquma, okanye iindlela zokuvuza.
Ingqikelelo yokusebenza yahlukile kulowo wenguqu yangoku yesigaba esiqhelekileyo. Endaweni yokulinganisa i-conductor enye kuphela, ii-conductor zesekethe ekhuselweyo zidlula kwi-core magnetic. Xa imisinga ehamba ngee-conductor ilungelelaniswa, iziphumo zabo zemagneti zirhoxisa kakhulu. Xa impazamo ibangela ukuba i-current ihambe ngendlela engacetywanga, i-residual field magnetic ikhula kwi-core kunye ne-second winding ivelisa isignali ehambelanayo.
Lo mgaqo wokusebenza uvumela i-transformer ukuba isebenze kunye ne-relays zokukhusela kunye nezinye izixhobo zokubeka iliso. Kwiinjineli zombane kunye nabahlanganisi benkqubo, isixhobo ke ngoko sisebenza njengenxalenye ebalulekileyo yokuva ngaphakathi kweskimu sokukhusela umhlaba jikelele.
Umgaqo wokusebenza unxulumene ngokusondeleyo noMthetho wangoku waseKirchhoff. Kwisekethe yezigaba ezithathu ezilungeleleneyo, isixa sevektha yemisinga yesigaba ithiyori nguziro:
Ia + Ib + Ic = 0
Ngenxa yoko, i-flux yamagnetic eyenziwe ngaphakathi kumbindi iyancitshiswa kwaye imveliso yesibini ihlala incinci kakhulu.
Xa impazamo yomhlaba isenzeka, inxalenye yangoku ishiya isiphaluka esicetywayo ngendlela engalindelekanga. Ibhalansi yangoku iphazamisekile:
Ia + Ib + Ic ≠ 0
Isiphumo sentsalela yangoku senza i-magnetic flux kumbindi. Ukujija okwesibini emva koko kuvelisa isignali yombane enokuthi ibonwe nge-relay yokukhusela.
Ulandelelwano oluqhelekileyo lokhuseleko lunokushwankathelwa ngolu hlobo lulandelayo:
Le nkqubo ivumela inkqubo yokukhusela ukuba ibone i-residual current engaqhelekanga ngaphandle kokuthembela kuphela kwimilinganiselo evela kwi-transformer yesigaba somntu ngamnye.
Ukusetyenziswa kombane kwimizi-mveliso, ukwakhiwa koomatshini kunye nokusebenza kwe-electromagnetic kubaluleke ngokulinganayo. I-Anqiang Power's LXK series isebenzisa idizayini engundoqo edibeneyo kunye ne-epoxy resin vacuum casting, evumela ukuba i-transformer ifakwe kwiintambo eziphambili ezikhoyo ngaphandle kokufuna ukususwa kwentambo. Oku kunokuba luncedo ngakumbi kwiiprojekthi ze-retrofit kunye nokugcinwa apho ukunciphisa ixesha lokunciphisa kuyinto ephambili.
Iimpawu ezininzi kufuneka ziqwalaselwe xa kuhlolwa olu hlobo lwesiguquli:
Ezi mpawu zenza uyilo lwe-split-core ngokukodwa xa uphucula iziseko zombane ezikhoyo ngaphandle kokuguqulwa okubanzi kwesekethe yokuqala.
I-Zero Sequence Current Transformer inokudityaniswa kuluhlu olubanzi lokuhanjiswa kwamandla kunye neenkqubo zokukhusela. Indima yayo ephambili kukubonelela ngolwazi olushiyekileyo kwizixhobo zokukhusela okanye zokubeka iliso.
Usetyenziso oluqhelekileyo lubandakanya:
Ngokomzekelo, kwikhabhinethi yokusabalalisa, i-transformer inokubeka iliso kwii-conductor ezondla isiphaluka esisezantsi. Ukuba ukuwohloka kwe-insulation kubangela ukuba umsinga uqukuqelele emhlabeni, intsalela yangoku ingabonwa kwaye idluliselwe kwireyiji yokhuselo. I-relay inokugqiba ukuba imeko elinganisiweyo ifuna ukuphazamiseka kwesiphaluka.
Le ndlela ibalulekile kuba ukufunyanwa kwangaphambili kweemeko ezingaqhelekanga zangoku kunokunceda ukunciphisa umngcipheko wokonakaliswa kwesixhobo, ixesha elongezelelweyo lokuphumla, kunye neziganeko zokhuseleko lombane.
Ukukhetha iZero Sequence Current Transformer akufuneki isekelwe kubungakanani bokuvula kuphela. Iinjineli kufuneka zivavanye isixokelelwano sombane, indawo yofakelo, isidluliseli sokhuseleko, kunye nolungiselelo lomatshini kunye.
