Zithini iiparameter zobugcisa zee-transformers zohlobo olomileyo? Zithini imisebenzi yazo?

1. Iiparameter zobugcisa ze-transformer yohlobo olomileyo

Iitransformer zohlobo olomileyo zisetyenziswa kakhulu kwizibane zasekuhlaleni, kwizakhiwo eziphakamileyo, kwizikhululo zeenqwelo-moya, kwizixhobo ze-CNC zedokhi, njl. Kalula nje,

ii-transformers zohlobo olomileyo zibhekisa kwii-transformers ezine-iron cores kunye ne-windings ezingafakwanga ioyile yokukhusela.

Iiparameter zobugcisa ezifanelekileyo zee-transformers zohlobo olomileyo ziquka:

A. Umthamo olinganisiweyo (kVA): Umthamo onokuziswa ngexesha lokusebenza okuqhubekayo kwi-voltage elinganisiweyo kunye nomsinga olinganisiweyo.

B. I-voltage elinganisiweyo (kV): I-voltage esebenzayo enokumelana ne-transformer ngexesha lokusebenza ixesha elide.

Ukuze kuhlangatyezwane neemfuno zotshintsho lwe-grid voltage, icala le-transformer elinombane ophezulu lineempompo,

enokulungiswa ngokulungelelanisa inani leenguqu kwi-high-voltage winding ukuze kulawulwe i-output voltage kwicala le-low-voltage.

C. Umlinganiselo wamandla (A): Umlinganiselo wamandla uvumelekile ukuba udlule kwi-transformer ixesha elide ngaphantsi komlinganiselo wamandla.

D. Ukulahleka komthwalo (kW): Amandla asebenzayo atsalwa xa i-voltage elinganisiweyo kwi-frequency elinganisiweyo isetyenziswa kwi-terminal enye ejikelezayo kwaye

iiwindings eziseleyo zivulelekile. Zinxulumene nenkqubo yokusebenza kunye nokuveliswa kwephepha lesinyithi lesilicon eliphambili,

kunye ne-voltage esetyenzisiweyo.

E. Umsinga ongenamthwalo (%): Xa i-transformer iphantsi kombane olinganisiweyo kwaye icala lesibini lingenamthwalo, umsinga odlulayo

ukujika okuphambili kudla ngokubonakaliswa njengepesenti yamandla alinganisiweyo.

F. Ukulahleka komthwalo (kW): Cima i-wind yesibini ye-transformer uze ufake i-current elinganisiweyo kwi-wind yokuqala kwi-wind.

indawo yokumpompa elinganisiweyo. La ngamandla asetyenziswa yitransformer.

G. I-voltage ye-Impedance (%): Yenza i-short-circuit kwi-secondary winding ye-transformer kwaye wonyuse i-voltage kancinci kwi-primary winding.

Xa i-short-circuit current ye-secondary winding ilingana nexabiso elilinganisiweyo, i-voltage esetyenziswa kwicala eliphambili yi-impedance

I-voltage. Idla ngokubonakaliswa njengepesenti ye-voltage elinganisiweyo.

H. Inombolo yesigaba kunye nokuphindaphinda: Isigaba sesithathu simelwe ngu-S, kwaye isigaba esinye simelwe ngu-D. Isantya f sesizwe saseTshayina

umgangatho yi-50Hz. Kukho amazwe aphesheya ane-60Hz (njenge-United States). I. Ukunyuka nokupholisa kwamaqondo obushushu: Umahluko phakathi

ubushushu be-transformer winding okanye i-oyile ephezulu kunye nobushushu bendalo esingqongileyo bubizwa ngokuba bubushushu

ukunyuka komaleko weoyile ojikelezayo okanye ophezulu. Ixabiso elilinganiselweyo lokunyuka kobushushu be-transformer entywilisiweyo kwioyile yi-65K, kwaye

Ukunyuka kobushushu bomphezulu weoyile yi-55K. Kukwakho neendlela ezahlukeneyo zokupholisa: ukuzipholisa okuntywilisiweyo ngeoyile, ukuphola komoya onyanzelisiweyo, ukupholisa amanzi,

uhlobo lwetyhubhu, uhlobo lweshidi, njl.njl.

J. Inqanaba lokufakwa kobushushu: Kukho imigangatho yamanqanaba okufakwa kobushushu. Inqanaba lokufakwa kobushushu kwi-transformer ene-voltage ephezulu ye-35 kV kunye ne-rated

i-voltage ephantsi ye-10 kV imelwe njenge-LI200AC85/LI75AC35, apho i-LI200 ibonisa ukuba i-transformer ine-high-voltage lightning impulse

ukumelana nevolthi ye-200 kV, ivolthi yamandla ehlala inamandla ye-85 kV, kunye nevolthi yombane ophantsi omelana nevolthi ye-75 kV,

kunye ne-frequency yamandla enyamezela i-voltage ye-35 kV. Inqanaba lobushushu langoku leemveliso ze-transformer ezintywilisiweyo kwi-oyile ze-Aux High-Tech Co., Ltd.

yi-LI75AC35, nto leyo ebonisa ukuba i-transformer ine-voltage yokumelana nombane ene-voltage ephezulu ye-75 kV kunye ne-power frequency yokumelana nombane.

i-voltage ye-35 kV. Ngenxa yokuba i-voltage ephantsi yi-400 V, inokungahoywa.

K. Ileyibhile yeqela loqhagamshelwano: Ngokwendlela ubudlelwane besigaba phakathi kweengcingo eziphambili nezesibini ze-transformer, i-transformer

ii-windings zidibene kwiindidi ezahlukeneyo, ezibizwa ngokuba liqela loqhagamshelwano lwee-windings. Ukuze kwahlulwe unxibelelwano olwahlukileyo

Kumaqela, uphawu lwewotshi ludla ngokusetyenziswa, oko kukuthi, i-phasor ye-voltage yomgca kwicala le-voltage ephezulu isetyenziswa njengesandla eside sewotshi,

iqiniswe kwi-12, kwaye i-phasor ye-line voltage kwicala le-low-voltage isetyenziswa njengesandla esifutshane sewotshi. Inani lesandla esifutshane libonisa

ilebhile yeqela lonxibelelwano. Umzekelo, iDyn11 ibonisa ukuba ukujika okuphambili kuqhagamshelwe (unxantathu), kwaye ukujika okwesibini kuqhagamshelwe (inkwenkwezi).

enenqaku eliphakathi, kwaye inani leqela ngama-(11) amanqaku.
