CT PT Analyzer yog dab tsi?
Sep 20, 2026
Ib qho CT (Tam sim no Transformer) thiab PT (Potential Transformer) analyzer yog cov cuab yeej tshwj xeeb uas siv los ntsuas qhov kev ua tau zoo ntawm tam sim no thiab voltage transformers. Cov transformers no yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob, lub luag haujlwm rau kev ntsuas tam sim no thiab qhov hluav taws xob hauv siab -voltage circuits. Lub ntsuas ntsuas ntsuas qhov tseeb ntawm qhov hloov pauv thiab txheeb xyuas cov teeb meem muaj peev xwm xws li qhov tsis raug ntawm qhov sib piv, rwb thaiv tsev tawg, thiab lub peev xwm tsis txaus.
1. Kev kuaj tam sim no Transformer (CT).
Turns Ratio Testing: Xyuas kom meej tias CT hloov pauv piv nws cov nqi ntsuas, xyuas kom tseeb qhov ntsuas tam sim no.
Kev Ntsuas Burden: Paub meej tias CT tuaj yeem txhawb nqa cov khoom tshwj xeeb sab nraud (lub nra) thiab ua kom raug thoob plaws qhov ntau.
Ratio yuam kev thiab theem ua haujlwm: Kev ntsuam xyuas qhov tsis raug ntawm qhov sib piv ntawm thawj thiab theem nrab tam sim no, nrog rau theem hloov pauv, uas tuaj yeem cuam tshuam qhov ntsuas qhov tseeb.
Magnetizing Current: Ntsuas cov hlau nplaum tam sim no, qhia txog qhov poob ntawm lub transformer.
Polarity Test: Xyuas kom meej CT polarity, txhais tau tias cov zis yog nyob rau hauv theem nrog cov tswv yim tam sim no.
2. Muaj peev xwm Transformer (PT) kuaj
Turns Ratio Testing: Txheeb xyuas qhov tseeb qhov sib piv ntawm thawj thiab theem nrab windings rau kev ntsuas qhov tseeb voltage.
Kev Ntsuas Burden: Simulates qhov sib txawv ntawm kev thauj khoom kom paub meej tias PT tuaj yeem tuav cov khoom thauj yam tsis muaj kev cuam tshuam loj.
Voltage Accuracy: Sib piv cov zis hluav taws xob nrog tus nqi xav tau nyob rau hauv kev sim sib txawv.
Rwb thaiv tsev Resistance thiab Dielectric Test: Ntsuam xyuas PT lub rwb thaiv tsev tiv thaiv kom ntseeg tau tias nws tuaj yeem tiv taus qhov hluav taws xob siab yam tsis muaj kev ua haujlwm.
CT PT Analyzer Common Applications
Fais fab nroj tsuag - generator tiv thaiv thiab ntsuas circuits
Substations - qhov tseeb tam sim no thiab ntsuas voltage
Hluav taws xob siv hluav taws xob - metering transformer xyuas
Commissioning & txij nkawm – tshiab installation thiab xyuas raws sij hawm
