Dab tsi yog tag nrho cov load uas 500 KVA generator teeb tuaj yeem nqa tau? Puas yog 500kva generator teeb thiab 500kVA transformer muaj tib lub peev xwm thauj khoom?

Feem ntau, lub tshuab hluav taws xob teeb uas tau ntsuas hauv kVA (500 kVA hauv qhov no) muaj peev xwm xa 400 kW hauv cov xwm txheej ntsuas rau qee lub sijhawm. Feem ntau (tab sis tsis tas li) nws tuaj yeem xa mus txog 440 kW rau ib teev hauv kaum ob lub sijhawm. Koj lub tshuab hluav taws xob UNKNOWN yuav zoo li ntawd. Los tsis yog.

 

Lub transformer yuav zoo ib yam li qhov ntsuas . 400 kW hauv cov xwm txheej ntsuas rau qee lub sijhawm. Peb tsis tuaj yeem qhia tau tias koj lub tshuab hluav taws xob UNKNOWN teeb tsa thiab UNKNOWN transformer muaj tib yam kev ntsuas. Tab sis tej zaum lawv yog yam tsawg kawg uas zoo sib xws.

 

Lub tshuab tsim hluav taws xob muaj peev xwm suav nrog cov lus qhia nyuaj uas yuav hais qee yam xws li (piv txwv li) "qhov nruab nrab ntawm 75% ntawm lub zog ntsuas rau qhov nruab nrab 75% ntawm lub sijhawm". Txij li txhua lub cav sib txawv, koj yuav tsum mus yos hav zoov kom tau txais cov ntsiab lus tseeb.

 

Lub tshuab hluav taws xob tuaj yeem muab 500 kVA ntawm 100% ntawm nws qhov ntsuas. Raws nraim tib yam rau 500 kVA transformer.

Muaj qhov sib txawv ntawm cov thermal teb ntawm transformer thiab lub tshuab hluav taws xob, tab sis lub peev xwm ntawm 500 kVA yog tib yam. Lub tshuab hluav taws xob yuav nkag siab ntau dua rau cov khoom siv hluav taws xob, tab sis nws qhov ntsuas kVA yuav nyob twj ywm tib yam.

 

Qhov kev txwv rau lub tshuab hluav taws xob lossis lub tshuab hloov hluav taws xob uas teeb tsa qhov kev txwv tsis pub muaj peev xwm nqa tam sim no ntawm cov xov hlau uas ua rau lub tshuab winding. Tag nrho cov kev ntsuas load yog raws li thermal muaj peev xwm ntawm cov hlau. Yog li qhov tseeb ntawm qhov txwv kev thauj khoom yog tam sim no. Piv txwv li, cia kuv xav tias koj 500 kVA generator lossis transformer, ua haujlwm ntawm qhov hluav taws xob 25 kV. Tam sim no tag nrho load tam sim no yog 11.55 amps. Tam sim no, vim li cas los xij, qhov hluav taws xob raug txo los ntawm 5% rau 23.75 kV. Tam sim no lub peev xwm thauj khoom tshiab yog 475 kVA, tsis yog 500 kVA. Yog hais tias qhov voltage yog 5% ntau dua, lub peev xwm yuav yog 525 kVA txij li thaum (11.55A) x (26,250V) x (1.73)=525,000 VA.

Lub peev xwm thauj khoom ntawm 500 kVA transformer yog dab tsi?

500 kVA Transformer Load Capacity

Transformers nrog lub peev xwm ntawm 500 kVA yog cov khoom xa tawm, uas feem ntau yuav tsum tau ua haujlwm ntev - lub sijhawm ua haujlwm tsis pub dhau 85%. Yog hais tias lub hwj chim yog 0.8, ces lub peev xwm ntawm qhov no 500 kVA transformer yog hais txog320 kW tsi.

 

Muaj pes tsawg amps yog 500 kVA transformer?

Muaj pes tsawg lub tsev tuaj yeem ua 500 kVA transformer?

Piv txwv tias ib tsev neeg nruab nrab siv li 5 kW ntawm lub zog, 500 kVA transformer feem ntau tuaj yeem txhawb nqa ntawm175 mus rau 212 lub tsev. Qhov no yog xam los ntawm kev coj mus rau hauv tus account lub transformer lub zog tso zis (280-340 kW) thiab muab faib los ntawm qhov nruab nrab tsev neeg siv zog.
