Qhov sib txawv ntawm qhov zoo tib yam tam sim no transformer thiab xoom sequence tam sim no transformer
Jun 14, 2023| 1. Lub luag hauj lwm ntawm cov tam sim no zoo tib yam transformers
Ordinary tam sim no transformers muaj peev xwm hloov cov thawj tam sim no nrog ib tug loj tus nqi mus rau ib tug thib ob tam sim no nrog ib tug me me nqi los ntawm ib tug tej yam transformation piv, uas yog siv rau kev tiv thaiv, ntsuas thiab lwm yam hom phiaj. Piv txwv li, tam sim no transformer nrog kev hloov pauv ntawm 400/5 tuaj yeem hloov qhov tam sim no 400A mus rau 5A tam sim no.
2. Ua hauj lwm hauv paus ntsiab lus ntawm xoom sequence tam sim no transformer
Lub hauv paus ntsiab lus ntawm xoom-sequence tiv thaiv tam sim no yog raws li Kirchhoff txoj cai tam sim no: lub algebraic sum ntawm cov complex tam sim no ntws mus rau hauv ib qho ntawm lub voj voog yog sib npaug rau xoom. Thaum cov kab thiab cov khoom siv hluav taws xob zoo li qub, cov vector sum ntawm cov tam sim no ntawm txhua theem yog sib npaug rau xoom. Yog li ntawd, qhov thib ob sab winding ntawm xoom-sequence tam sim no transformer tsis muaj teeb liab tawm, thiab tus actuator tsis ua haujlwm. Thaum muaj teeb meem hauv av, qhov vector sum ntawm cov tam sim no ntawm txhua theem tsis yog xoom, qhov txhaum tam sim no ua rau cov hlau nplaum sib nqus tsim nyob rau hauv lub nplhaib hlau tub ntxhais ntawm xoom-sequence tam sim no transformer, thiab induced voltage nyob rau theem nrab ntawm lub xoom-sequence tam sim no transformer ua rau tus actuator ua thiab tsav Lub tripping ntaus ntawv hloov lub zog mov network kom ua tiav lub hom phiaj ntawm av txhaum kev tiv thaiv.
3. Muaj nuj nqi ntawm xoom sequence tam sim no transformer
Thaum muaj hluav taws xob poob lossis qhov ua txhaum tawm hauv Circuit Court, kev tiv thaiv yuav ua thiab txiav tawm lub hwj chim.
4. Cov xwm txheej ntawm kev siv xoom-sequence tam sim no transformers
Lub transformer tam sim no tuaj yeem ntsia tau rau ntawm txhua kab ntawm peb-theem, lossis xoom-sequence tam sim no transformer tuaj yeem dhau los ntawm peb-theem xaim ua ke, lossis xoom-sequence tam sim no transformer tuaj yeem ntsia tau rau ntawm kab nruab nrab N kom pom. three-phase Cov vector sum ntawm .
