Kev daws teeb meem rau cov cuab yeej hloov pauv (CT & PT)

Tshawb cov haujlwm tseem ceeb txog kev hloov pauv hloov (CT & PT)

 

Cov kev hloov pauv hluav taws xob yog ob hom:

 

1. Tam sim no hloov pauv (lossis series transformer)

Ib qho hloov pauv tam sim no (CT) yog lub cuab yeej uas siv los ntsuas qhov kev ntws tam sim no los ntawm tus neeg xyuas pib. Nws yog siv thaum lub zog ntawm AC uas muaj tus nqi nyab xeeb tshaj plaws ntawm cov twj paj nruag ntsuas, txo tus nqi rau kev ntsuas / kev tiv thaiv / tswj hwm. Qhov xwm txheej theem nrab yog 5 caj npab.

 

2. Muaj peev xwm hloov pauv (lossis voltage transformer)

Voltage transformer (PT) yog lub cuab yeej uas siv los ntsuas kev ntsuas siab rau kev ntsuas hluav taws xob kom raug. Nws yog tsim los nqis ntaiv cov qib siab kom muaj kev nyab xeeb dua thiab ntsuas tau ntau qib. Tus pts hloov pauv siab-voltage Systems kom muaj voltage qis, yog li lawv tau sib haum nrog meters, xa tawm, thiab lwm yam ntsuas siv hluav taws xob. yog siv qhov chaw hluav taws xob uas yog AC Circience tshaj li 750 v li tsis muaj peev xwm los muab rwb thaiv tsev kom ntsuas seb qhov ntsuas ntau tshaj qhov no.

Nws yog qhov tseem ceeb rau kev sim CT thiab PT los xyuas kom muaj kev nyab xeeb ntawm cov neeg siv thiab khoom siv. Yog tias cov khoom siv no yog qhov yuam kev lossis tsis ua haujlwm kom raug, lawv tuaj yeem ua rau muaj kev phom sij rau cov neeg uas siv lawv lossis cov cuab yeej lawv txuas nrog. Kuaj cov khoom siv no ua ntej kev teeb tsa yuav pab txheeb xyuas cov tsis xws lossis lwm yam teeb meem thiab tiv thaiv lawv los ntawm kev ua kom muaj kev phom sij.

Txhawm rau paub meej tias cov yam ntxwv ntawm lub cev thiab hluav taws xob ntawm tus hloov pauv hloov tam sim no tau nruab rau hauv kev teeb tsa. Nco ntsoov tias CT yog txuas nrog cov txheej txheem kom zoo nyob hauv txhua qhov kev cuam tshuam (thawj thiab theem nrab).
