Umbuzo 1) yintoni i-transformer yezixhobo?

Ukuba sifuna ukulinganisa amaxabiso aphezulu kakhulu ombane kunye ne-voltage, kukho iindlela ezimbini zokuyilinganisa. Enye kukusebenzisa izixhobo ezinomthamo ophezulu eziya kuba zibiza kakhulu. Enye indlela kukusebenzisa ipropathi yokuguqula umbane kunye ne-voltage.

Umbane kunye nombane zinokuthotywa ngokusebenzisa i-transformer eyaziwa ngokuba yi-turn's ratio ize emva koko ilinganise umbane kunye nombane othotywe nge-ammeter okanye i-voltmeter eqhelekileyo. Ubukhulu bokuqala bungamiselwa ngokuphindaphinda ubukhulu obuthotywe ngomlinganiselo wokujikeleza. Olu hlobo lwe-transformer olwakhiwe ngokukodwa olunomlinganiselo ochanekileyo wokujikeleza lubizwa ngokuba yi-instrument transformer. Kukho iintlobo ezimbini ze-instrument transformer:

1) Isiguquli sangoku

2) Isiguquli esinokwenzeka.

Umbuzo 2) zithini ii-transformers zangoku?

I-current transformer ifakwa ngokulandelelana kunye nomgca apho umbane uza kulinganiswa khona. Zisetyenziselwa ukwehlisa umbane uye kwinqanaba elinjalo ukuze ukwazi ukulinganiswa ngokulula ngokusebenzisa i-ammeter. Ngokubanzi zichazwa njengomlinganiselo wamandla osisiseko: wesibini umz.: I-100:5 amp CT iya kuba nombane osisiseko we-100 Amp kunye nombane wesibini we-5 Amp.

Uvavanyo oluqhelekileyo lwesibini lwe-CT's luyi-5 okanye i-1 Amp's

Ukusetyenziswa okuqhelekileyo kwe-CT efumanekayo kwimarike yi-"clamp meter".

Umbuzo 3) ziintoni ii-transformer ezinokubakho?

Iitransformer ezinokubakho zikwaziwa ngokuba ziitransformer zevolthi kwaye ngokusisiseko ziitransformer ezisezantsi ezinereyithingi yokujika echanekileyo kakhulu. Iitransformer ezinokubakho zihla ivolthi ephezulu ukuya kwivolthi ephantsi enokulinganiswa ngesixhobo sokulinganisa esiqhelekileyo. Ezi transformer zinenani elikhulu lokujika okuphambili kunye nenani elincinci lokujika okungasemva.

I-potential transformer idla ngokubonakaliswa ngokwe-primary to secondary voltage ratio. Umzekelo, i-600:120 PT ingathetha ukuba i-voltage kwi-secondary yi-120 volts xa i-primary voltage iyi-600 volts.

Umbuzo 4) yintoni umahluko phakathi kwe-current kunye ne-power transformer?

Kwinqanaba elisisiseko, azifani. Zombini zisebenza ngomgaqo wokungenisa i-electromagnetic. Kodwa umahluko usekusetyenzisweni kwazo.

Ii-current transformers, eziphantsi kodidi lwee-Instrument transformers, zisetyenziswa kakhulu kunye nezinye izixhobo ngenjongo yokulinganisa. Njengakwezinye izixhobo ezisetyenziselwa ukulinganisa kwiisekethe zombane, ii-current transformers kufuneka zibe ne-impedance ephantsi kakhulu ukuze zingayichaphazeli i-current kwisekethe eziyilinganisayo ngobuninzi obukhulu. Kwakhona kubaluleke kakhulu ukuqinisekisa ukuba umahluko wesigaba phakathi kwe-primary currents kunye ne-secondary currents usondele kakhulu kwi-zero. I-current transformer ikwanayo ne-turn encinci kakhulu, okanye nokuba yi-turn enye kwi-primary kwaye uninzi kwi-secondary.

Kwelinye icala, ii-power transformers zisetyenziselwa ukudlulisa amandla ukusuka kwicala eliphambili ukuya kwelinye. Apha ugxininiso alukho kangako ekunciphiseni i-impedance kwi-transformer, kwaye alukho kakhulu ekunciphiseni impazamo ye-phase angle ekufutshane ne-zero. Apha ugxininiso lubekwe ngakumbi ekusebenzeni kakuhle kunokuchaneka. Okwesibini, i-power transformer inee-turns ezininzi kakhulu kwi-primary yayo, kune-turn enye, nangona isengaphantsi kunezo zikwi-secondary.

Umbuzo 5) Ngowuphi umatshini onokuvelisa i-current kunye ne-potential transformer?

Kukho iindlela ezimbini zokusebenzisa i-epoxy resin current transformer, endala neyakudala yi-vacuum casting tank, ebizwa ngokuba yi-. iteknoloji yokukhupha i-vacuum,Itekhnoloji yesibini yamva nje yile Itekhnoloji ye-APG (i-automatic pressure gelation) ,Umatshini wokuphosa yi-APG clamping machine,ekwabizwa ngokuba yi-APG machine,i-epoxy resin apg machine,Ngoku umatshini we-APG lukhetho lokuqala lwabasebenzisi.Kuba ngaphantsi kwezibonelelo:

1. Ukusebenza kakuhle kwemveliso, thabatha imveliso ye-10KV CT umzekelo, ungafumana i-CT efanelekileyo kwimizuzu engama-30.
2. Utyalo-mali，Ixabiso lomatshini we-APG malunga ne-55000-68000USD
3. Ufakelo, kufuneka uqhagamshele umbane kuphela, emva koko unokuqhuba umatshini
4. Ukusebenza koMbane, ukukhupha kancinci, ukumelana neekhemikhali, ubushushu bombane, ukumelana namandla kuphuculwe kakhulu, sinezixhobo zokuvavanya ezisebenza nathi.
5. Isidanga sokuZenzekelayo: Kufuneka abasebenzi abali-1-2 kuphela abasebenzisa umatshini, ukusebenza kakuhle kuyanda kakhulu kodwa amandla abasebenzi ayancipha. Kufuneka nje izitshixo zolawulo kwikhabhathi yamandla.
6. Ukusebenza, Kulula ukuyisebenzisa i-APG machine, injineli yethu iya kubonisa indlela yokuyisebenzisa kwaye sinencwadi yesikhokelo yokusebenzisa i-machine yethu, akukho mfuneko yokuhlawula umvuzo ophezulu ukuze kuqeshwe iinjineli ezingoochwephesha ukuze zisebenzise i-machine.

Ungaya kwitshaneli yethu ye-youtube, ukuze ubone iividiyo zokusebenza kwalo matshini.
