Dab tsi yog qhov kev sib raug zoo ntawm qhov kub thiab txias thiab kev pab cuam lub neej ntawm qhuav faib transformer?

Kub yog ib lub tswv yim ntawm ib puag ncig sab nraud. Kev khiav hauj lwm ib puag ncig ntawm ddry tis transformer kuj raug cuam tshuam thiab txwv los ntawm qhov kub thiab txias. Yog tsis muaj qhov kub zoo, nws tsis tuaj yeem ua kom qhuav-hom transformers ua haujlwm zoo. Rau qhov kub ntawm cov tshuab ziab khaub ncaws qhuav, Nws tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm cov tshuab ziab khaub ncaws qhuav, tab sis kuj cuam tshuam rau kev pab cuam lub neej ntawm cov tshuab ziab khaub ncaws qhuav. Yog li ntawd, nws yog ib qho tsim nyog kom nkag siab qhov ntsuas kub ntawm lub tshuab ziab khaub ncaws qhuav thiab ua haujlwm ntawm cov khoom siv hluav taws xob qhuav ntawm qhov ntsuas kub, uas yog qhov tsim nyog rau kev txhim kho cov ziab-hom transformer. kev pab cuam lub neej ntawm lub transformer. Yog li kev sib raug zoo ntawm ob leeg yog dab tsi?

1. Kev sib raug zoo ntawm kev pabcuam lub neej ntawm cov khoom siv hluav taws xob qhuav thiab cov rwb thaiv tsev kub:

Feem ntau ntawm lub zog qhuav-hom transformers siv roj-ntawv rwb thaiv tsev, uas yog, Class A rwb thaiv tsev. Rau cov tshuab ziab khaub ncaws qhuav nrog Class A rwb thaiv tsev, hauv kev ua haujlwm ib txwm muaj, thaum huab cua kub ib puag ncig yog 40 degree, qhov txwv kev ua haujlwm kub ntawm qhov ziab-hom transformer windings yog 105 degree.

Kev xyaum thiab kev tshawb fawb tau pom tias yog lub winding muaj peev xwm tswj tau qhov kub ntawm 95 degree tsis tu ncua, lub tshuab ziab khaub ncaws tuaj yeem lav tias muaj kev pab cuam lub neej ntawm 20 xyoo. Raws li kev sib raug zoo ntawm qhov kub thiab txias, lub npe hu ua 8 degree txoj cai kuj tuaj yeem muab tau: raws li lub neej ntawm qhov kub thiab txias, lub neej kev pab cuam ntawm lub tshuab ziab khaub ncaws yuav luv luv los ntawm 1/2 txhua zaus winding. kub nce 8 degree.

Raws li cov ntaub ntawv tseem ceeb thiab kev coj ua pov thawj:

Thaum lub rwb thaiv tsev ua hauj lwm kub ntawm qhuav-hom transformer yog 95 degree, kev pab cuam lub neej ntawm qhuav-hom transformer yog 20 xyoo.

Kev ua haujlwm kub ntawm cov tshuab hluav taws xob qhuav yog 105 degree, thiab kev pabcuam lub neej ntawm cov tshuab ziab khaub ncaws qhuav yog 7 xyoo.

Thaum lub rwb thaiv tsev ua hauj lwm kub ntawm qhuav-hom transformer yog 120 degree, kev pab cuam lub neej ntawm qhuav-hom transformer yog 2 xyoo.

2. Kho qhov qhuav-hom transformer load kom ua kom qhuav-hom transformer ncav cuag lub zoo tagnrho kev pab cuam lub neej:

Raws li qhov tseeb tias qhov hluav taws xob yog qhov tsis tu ncua, qhov ntsuas kub ntawm qhov hluav taws xob hauv lub tshuab hluav taws xob qhuav yog feem ntau cuam tshuam nrog kev thauj khoom tam sim no, uas yog, qhov hluav taws xob tam sim no loj, qhov ntsuas kub ntawm qhov hluav taws xob yog siab, thiab qhov hluav taws xob rwb thaiv tsev yog qhov tsawg. load tam sim no me me.

Qhov kub ntawm qhov qhuav-hom transformer yog ze ze rau qhov kev pab cuam lub neej ntawm qhuav-hom transformer. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ntsuas qhov ntsuas kub ntawm lub tshuab ziab khaub ncaws kom paub meej tias lub tshuab ziab khaub ncaws qhuav ua haujlwm ntawm qhov ntsuas kub, kom lub tshuab ziab khaub ncaws tuaj yeem ua lub luag haujlwm ntau dua. Qhov zoo los xyuas kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov tshuab ziab khaub ncaws qhuav!
