Distribution Transformer Power Rating
Kev faib tawm transformers yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob hluav taws xob. Lawv yog siv los txo qis qhov hluav taws xob los ntawm qib siab hauv cov kab sib kis mus rau qib qis uas tsim nyog rau kev faib mus rau cov neeg siv kawg. Kev ntsuas hluav taws xob ntawm lub tshuab hluav taws xob faib hluav taws xob yog qhov ntsuas tseem ceeb uas txiav txim siab nws lub peev xwm xa hluav taws xob rau cov khoom thauj. Hauv tsab xov xwm no, peb yuav tham txog cov yam tseem ceeb uas cuam tshuam rau qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob faib hluav taws xob thiab qhov tseem ceeb ntawm kev xaiv lub tshuab hloov hluav taws xob nrog qhov ntsuas hluav taws xob zoo rau koj daim ntawv thov.
Kev ntsuas hluav taws xob ntawm lub tshuab hluav taws xob faib hluav taws xob tau teev nyob rau hauv cov nqe lus ntawm nws qhov ntsuas kVA (Kilovolt-Ampere). Qhov kev ntsuam xyuas no yog qhov ntsuas ntawm lub zog siab tshaj plaws uas lub tshuab hloov pauv tuaj yeem xa mus rau qhov chaw thauj khoom yam tsis tau tshaj nws qhov ntsuas kub nce. Kev ntsuas kVA yog txiav txim siab los ntawm tus nqi ntawm lub zog uas yuav tsum tau xa mus rau lub nra, lub peev xwm nqa tam sim no ntawm lub tshuab hloov pauv, thiab cov yam ntxwv thermal ntawm lub tshuab hluav taws xob rwb thaiv tsev.
Ib qho ntawm qhov tseem ceeb tshaj plaws uas cuam tshuam rau qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob faib hluav taws xob yog qhov thauj khoom tam sim no. Raws li lub load tam sim no nce, lub transformer yuav tsum xa ntau zog, uas yuav ua rau cua sov nyob rau hauv lub transformer windings. Yog li ntawd, lub hwj chim ntsuam xyuas ntawm lub transformer yuav tsum raug xaiv kom tsawg kawg yog sib npaug zos rau qhov siab tshaj plaws load tam sim no uas nws yuav tsum tau xa.
Lwm qhov tseem ceeb uas cuam tshuam rau qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob faib khoom yog qhov kub thiab txias. Lub tshuab hluav taws xob rwb thaiv tsev yog tsim los ua haujlwm nyob rau hauv qhov kub thiab txias, thiab yog tias qhov kub thiab txias siab dhau lawm, lub peev xwm xa hluav taws xob tuaj yeem txo qis. Yog li ntawd, nws yog ib qho tseem ceeb los xav txog qhov kev cia siab ntawm qhov kub thiab txias hauv qhov chaw teeb tsa thaum xaiv qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob.
Hom kev thauj khoom kuj tuaj yeem cuam tshuam qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob faib khoom. Qee hom kev thauj khoom, xws li lub cev muaj zog thiab lub tshuab hluav taws xob, tuaj yeem tsim cov dej ntws tawm uas muaj ntau dua li lawv cov dej ntws tsis tu ncua. Cov inrush tam sim no tuaj yeem ua rau cov cua kub tseem ceeb hauv transformer windings, uas tuaj yeem txo nws lub peev xwm xa hluav taws xob. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xav txog hom kev thauj khoom thaum xaiv lub zog ntsuas ntawm lub tshuab hloov hluav taws xob.
Hauv cov ntsiab lus, qhov ntsuas hluav taws xob ntawm qhov hloov pauv hloov pauv yog qhov tseem ceeb uas txiav txim siab nws lub peev xwm xa hluav taws xob rau cov khoom thauj. Cov yam tseem ceeb uas cuam tshuam rau qhov ntsuas hluav taws xob muaj xws li qhov ntsuas tam sim no, qhov kub thiab txias, thiab hom load. Nws yog ib qho tseem ceeb los xaiv qhov tsim nyog lub zog ntsuas rau koj daim ntawv thov kom ntseeg tau tias kev ua tau zoo thiab tiv thaiv kev puas tsuaj rau lub transformer. Nco ntsoov sab laj nrog tus kws tshaj lij hluav taws xob tsim nyog los xyuas kom meej qhov kev xaiv thiab kev teeb tsa kom raug.
