Umgaqo

Xa i-voltage transformer isebenza ngokuqhelekileyo, i-voltage yesigaba sesithathu senkqubo yamandla i-symmetrical, kwaye isimbuku sesigaba sesithathu samandla ombane we-electromotive kwikhoyili yesithathu ngu-zero.Emva kokuba isiseko sesigaba esisodwa senzeke, indawo engathathi hlangothi iya kususwa, kwaye i-voltage ye-zero-sequence iya kubonakala phakathi kwee-terminals ze-triangle evulekileyo ukwenza i-relay isenzo, ngaloo ndlela ikhusela inkqubo yamandla.Xa i-voltage ye-zero-sequence ibonakala kwikhoyili, i-zero-sequence magnetic flux iya kubonakala kwi-core yentsimbi ehambelanayo.Ukuza kuthi ga ngoku, lo mguquli wombane wesigaba esithathu wamkela isiseko sedyokhwe esecaleni (xa i-10KV nangaphantsi) okanye i-voltage yesigaba esinye sesithathu.Kulolu hlobo lwe-transformer, ukuchaneka kwekhoyili yesithathu ayiphezulu, kodwa ifuna iimpawu ezithile zokugqithisa (oko kukuthi, xa umbane oyintloko unyuka, ubuninzi be-magnetic flux kumbindi wentsimbi nawo kwandisa ngokuphindaphindiweyo okuhambelanayo ngaphandle komonakalo).

Kutheni kufuneka utshintshe i-voltage kumgca?Oku kungenxa yokuba ngokweemeko ezahlukeneyo zokuvelisa amandla, ukuhanjiswa kunye nokusetyenziswa kombane, i-voltages kwimigca iyahluka ngobukhulu, kwaye umahluko uhluke kakhulu.Ezinye zi-low-voltage 220V kunye ne-380V, kwaye ezinye zi-high-voltage amashumi amawaka e-volts okanye namakhulu amawaka e-volts.Ukulinganisa ngokuthe ngqo ezi zi-voltage eziphantsi kunye ne-high-voltage, kuyimfuneko ukwenza i-voltage ephantsi kunye ne-high-voltage voltmeters kunye nezinye izixhobo kunye neelayidi ngokuhambelana nobukhulu bombane womgca.Oku akuyi kuzisa kuphela ubunzima obukhulu ekwenzeni isixhobo, kodwa okona kubaluleke kakhulu, akunakwenzeka kwaye kunqatshelwe ngokupheleleyo ukwenza ngokuthe ngqo isixhobo sombane ophezulu kunye nokulinganisa umbane ngokuthe ngqo kumgca we-voltage ephezulu.

Ukulumkela

1. Ngaphambi kokuba i-voltage transformer isetyenziswe, uvavanyo kunye nokuhlolwa kuya kwenziwa ngokwezinto ezichazwe kwimimiselo.Umzekelo, ukulinganisa i-polarity, iqela lokudibanisa, ukugquma ukugquma, ukulandelelana kwesigaba senyukliya, njl.

2. I-wiring ye-voltage transformer kufuneka iqinisekise ukuchaneka kwayo.Umoya ophambili kufuneka udityaniswe ngokuhambelana nesekethe phantsi kovavanyo, kwaye ukuvuthwa kwesibini kufuneka kudityaniswe ngokuhambelana ne-coil ye-voltage yesixhobo sokulinganisa esixhunyiwe, isixhobo sokukhusela i-relay okanye isixhobo esizenzekelayo.Ngelo xesha, ingqalelo kufuneka ihlawulwe ekuchanekeni kwe-polarity..

3. Umthamo womthwalo oqhagamshelwe kwicala lesibini le-voltage ye-voltage kufuneka ulungele, kwaye umthwalo oqhagamshelwe kwicala lesibini le-voltage ye-voltage akufanele udlule umthamo wayo olinganisiweyo, ngaphandle koko, impazamo ye-transformer iya kwanda, kwaye kunzima ukufezekisa ukuchaneka komlinganiselo.

4. Akukho mjikelezo omfutshane uvunyelwe kwicala lesibini le-voltage transformer.Ekubeni i-impedance yangaphakathi ye-voltage transformer incinci kakhulu, ukuba isiphaluka sesibini sifutshane, kuya kuvela umsinga omkhulu, oya kulimaza izixhobo zesibini kunye nokuba yingozi yokhuseleko lomntu.I-voltage transformer inokuxhotyiswa nge-fuse kwicala lesibini ukuzikhusela ekonakalisweni yisiphaluka esifutshane kwicala lesibini.Ukuba kunokwenzeka, i-fuses kufuneka ifakwe kwicala eliphambili ukukhusela igridi yamandla e-high-voltage engozini yokhuseleko lwenkqubo ephambili ngenxa yokungaphumeleli kwe-transformer's high-voltage windings okanye iingcingo ezihamba phambili.

5. Ukuze kuqinisekiswe ukukhuseleka kwabantu xa bechukumisa izixhobo zokulinganisa kunye nee-relays, i-second winding ye-voltage transformer kufuneka ibekwe phantsi kwinqanaba elinye.Ngenxa yokuba emva kokumiswa komhlaba, xa ukugquma phakathi kwe-winding ephambili kunye neyesibini yonakele, kunokuthintela i-voltage ephezulu yesixhobo kunye ne-relay engozini yokhuseleko lomntu.

6. Isiphaluka esifutshane asivumelekanga ngokupheleleyo kwicala lesibini le-voltage transformer.
