Dab tsi yuav tsum tau ceev faj thaum txhim kho tam sim no transformers?
Jun 01, 2026| 1. Polarity thiab kev taw qhia yuav tsum raug: Thawj sab terminals yog cim P1 thiab P2. Tam sim no yuav tsum ntws mus rau P1 thiab tawm los ntawm P2.
P1 yuav tsum fim rau sab fais fab mov (piv txwv li, transformer los yog cov kab nkag), thiab P2 yuav tsum fim lub load sab; txwv tsis pub, lub ntsuas hluav taws xob yuav thim rov qab thiab kev tiv thaiv yuav ua haujlwm tsis zoo.
Nyob rau theem nrab, S1 txuas nrog lub davhlau ya nyob twg zoo ntawm cov khoom ntsuas, thiab S2 txuas nrog lub davhlau ya nyob twg tsis zoo thiab muaj kev ntseeg siab.
2. Secondary Sab Hlau Hlau thiab Kev Nyab Xeeb Specifications:
Qhib Circuit Court nyob rau theem ob yog nruj me ntsis txwv tsis pub: qhib Circuit Court thaum lub sij hawm ua hauj lwm yuav induce phav phav volts ntawm high voltage, ua phem rau cov neeg ua hauj lwm thiab cov cuab yeej muaj kev ruaj ntseg. Ua ntej kev saib xyuas, terminals S1-S2 yuav tsum tau luv luv.
Siv cov tub ntxhais tooj liab hlau nrog tus ntoo khaub lig- thaj tsam loj dua lossis sib npaug ntawm 2.5mm², thiab qhov ntev yuav tsum tsis pub tshaj 50m kom txo qis voltage.
S2 davhlau ya nyob twg yuav tsum tau grounded ntawm ib qho chaw: Qhov no tiv thaiv ntau lub hauv paus ntsiab lus los ntawm kev tsim cov circulating tam sim no uas cuam tshuam nrog cov cuab yeej tiv thaiv.
3. Cov kev xav tau ntawm kev txhim kho sab hauv
Rau los ntawm - hom CTs, xyuas kom cov conductors hla dhau vertically thiab nruab nrab kom tsis txhob eccentricity, uas tuaj yeem ua rau sib nqus Circuit Court asymmetry thiab ntsuas qhov yuam kev.
Thaum ntau lub cables dhau los ntawm cov tub ntxhais, peb -theem kev sib txuas yuav tsum sib luag, tshwj xeeb tshaj yog nyob rau hauv xoom- raws li kev ntsuas tam sim no.
Qhib- hom CTs yuav tsum raug kaw kom ruaj ntseg tom qab kev teeb tsa los tiv thaiv kev sib nqus hluav taws xob los ntawm kev cuam tshuam kev ua haujlwm.
4. Ib puag ncig thiab kho cov kev xav tau
Qhov chaw teeb tsa yuav tsum qhuav thiab zoo- qhov cua, kom deb ntawm qhov chaw muaj zog electromagnetic cuam tshuam (xws li transformers thiab siab - fais fab zaus converters).
Vertical installation qaij Tsawg dua los yog sib npaug li 1 degree, ruaj ruaj kom tiv thaiv kev vibration thiab loosening.
Thaum muab tso rau hauv lub thawv xa khoom, tawm ntau dua lossis sib npaug li 80 hli ntawm qhov cua nkag rau saum toj.
5. Tig qhov sib piv thiab Load Matching
Qhov kev hloov pauv yuav tsum raug xaiv kom qhov kev khiav hauj lwm tam sim no nyob rau hauv 60% ~ 120% ntawm tus nqi ntsuas los xyuas kom meej qhov ntsuas qhov tseeb.
Tag nrho cov impedance ntawm cov cuab yeej txuas nrog rau sab thib ob yuav tsum tsis pub tshaj CT's rated load (piv txwv li, 15VA), txwv tsis pub nws yuav ua rau muaj kev ua yuam kev ntau ntxiv lossis saturation.
