Puas yog 315 kva faib transformer ua haujlwm rau 500KVA load?

Lub Transformer uas peb siv los muab cov khoom thauj yuav tsum muab ob qho tib si Active zog thiab Reactive zog thov los ntawm lub load. Yog tias peb siv 315KVA transformer rau muab 500KVA load ces muaj caij nyoog uas lub transformer yuav puas vim overload.

 

Lwm qhov teeb meem yog tias, 500KVA yog tag nrho cov kev siv hluav taws xob los ntawm kev thauj khoom ntawm Rated mob yog li yog tias peb tab tom khiav haujlwm ntawm lub zog qis.
noj cov xwm txheej xws li tias tag nrho cov hluav taws xob noj yog 315KVA lossis qis dua qhov ntawd ces yuav muaj lub sijhawm uas peb tuaj yeem ua haujlwm 500KVA load los ntawm 315KVA transformer.

 

Nws yuav ua haujlwm. Tab sis nyob ntawm qee yam. Muaj ib yam hu ua overloading factor uas qhia txog qhov piv ntawm kev tso cai overload rau rated load.

Yuav muaj hluav taws xob ntau dua thaum koj hla lub transformer nrog 500kVA load. Yog tias muaj cua txias txaus ces nws tuaj yeem thauj khoom tshaj nws cov nqi ntsuas.

Kev ua haujlwm ntau dhau yog ua tiav hauv lub zog hloov pauv nrog cov txheej txheem txias ntxiv xws li OFAF (roj quab yuam cua yuam) [roj yog pumped kom nce tus nqi ntawm cov roj ntws hauv cov roj transformer ua lub coolant thiab cua ntws yog nce los ntawm ntau cov kiv cua txuas nrog fin kom nce cov cua kub dissipation tus nqi]

 

Dab tsi yog qhov specification ntawm 315 kVA transformer?

 

Nominal system voltages rau 315 KVA transformers yog 11KV, nrog tus qauv voltage piv ntawm 11000/400V. Ntau lub teb chaws muaj qhov sib txawv me ntsis voltage. Tsis tas li ntawd, nws muaj qhov tshwj xeeb ntawm kev thauj khoom poob ntawm 2800W thiab tsis muaj -load poob ntawm 324W.

Lub epoxy resin qhuav hom transformer muaj cov yam ntxwv ntawm kev ua tau zoo hluav taws xob, muaj zog xob laim cuam tshuam, muaj zog luv luv -circuit resistance, me me, thiab lub teeb yuag. Lub ntsuas kub tso saib tuaj yeem ntsia tau los tso saib thiab tswj kev ua haujlwm kub ntawm lub tshuab hloov hluav taws xob kom ntseeg tau tias lub neej ua haujlwm zoo ntawm lub tshuab hloov pauv.

 

Kev ua haujlwm ntawm kub tswj:

Raws li qhov kub thiab txias, lub kiv cua txias yuav tsum tswj kom nres, overtemperature tswb thiab ultra- kub tripping kom ntseeg tau tias muaj kev nyab xeeb ntawm qhuav fais fab transformer.
