Lub tshuab nqus tsev Circuit Court Breakers (VCBs) tau siv dav hauv nruab nrab -voltage fais fab faib tshuab vim lawv txoj kev ntseeg siab, kev saib xyuas qis, thiab kev nyab xeeb ib puag ncig. Lub 33kV VCB yog ib qho kev ntsuam xyuas ntau hauv ntau cov khoom siv hluav taws xob. Nws yog ib qho tsim nyog yuav tsum tau sim thiab saib xyuas cov kab hluav taws xob no kom paub tseeb tias kev tiv thaiv kev tiv thaiv thiab kev nyab xeeb ntawm kev ua haujlwm. Kab lus no qhia txog cov txheej txheem los ntsuas 33kV lub tshuab nqus tsev vacuum siv lub ntsuas hluav taws xob ntsuas hluav taws xob.
Lub Circuit Court breaker analyzer yog cov cuab yeej kuaj xyuas qib siab uas tsim los ntsuas qhov kev ua tau zoo ntawm cov hluav taws xob hluav taws xob, suav nrog hom nqus tsev. Nws ua cov kev ntsuam xyuas tseem ceeb xws li kev ntsuas kev tiv thaiv kev tiv thaiv, kev tiv thaiv kev tiv thaiv kev sib cuag (DCR), kev tshawb xyuas lub sijhawm (qhib thiab kaw lub sijhawm), kev soj ntsuam cov lus tsa suab, thiab cov yam ntxwv tsis zoo. Kev siv cov cuab yeej no txhim kho qhov tseeb, txo cov kev ua yuam kev ntawm phau ntawv, thiab pab tshawb xyuas cov cim thaum ntxov ntawm kev hnav lossis tsis ua haujlwm.
Yuav kuaj 33kV VCB li cas nrog Circuit Breaker analyzer?
1. Kev npaj thiab kuaj xyuas kev nyab xeeb
- Xyuas kom lub Circuit Court breaker yog cais thiab de-energized ua ntej pib.
- Pom kev tshuaj xyuas lub tshuab tawg rau txhua qhov kev puas tsuaj, cov roj xau (yog tias tsim nyog), lossis muaj kev sib kis.
- Tshawb xyuas txhua qhov chaw muaj kev nyab xeeb thiab kev sib txuas sim ua raws li cov qauv tsim nyog.
- Nrog rau cov chaw tsim khoom phau ntawv qhia txog kev rhuav tshem -cov lus qhia tshwj xeeb.
2. Txuas cov khoom siv kuaj.
- Txuas ruaj ntseg rau CB analyzer cov sensors tam sim no thiab qhov hluav taws xob ua rau lub breaker lub ntsiab tam sim no - nqa cov terminals.
- Txuas tswj ua rau kev khiav hauj lwm lub breaker qhib thiab kaw mechanism remotely los ntawm lub analyzer.
- Xyuas kom txhua qhov kev sib txuas yog nruj thiab rwb thaiv tsev kom tiv thaiv kev sib cuag tsis raug.
3. Hu rau Kev Ntsuas Kev Tiv Thaiv
- Pib qhov kev ntsuam xyuas tiv thaiv kev tiv thaiv siv lub ntsuas ntsuas los ntsuas qhov tsis kam ntawm lub ntsiab tam sim no - nqa cov neeg sib cuag.
- Kev tiv thaiv qis qhia tau hais tias muaj hluav taws xob zoo; Tus nqi raug rau 33kV VCB cov kab sib txuas hauv micro-ohms.
- Kev tiv thaiv siab tsis zoo yuav qhia tau tias hnav lossis pitting, yuav tsum tau ntxuav lossis hloov pauv.
4. Sijhawm thiab Kev Ntsuas Kev Ntsuas
- Ua haujlwm qhib thiab kaw siv lub ntsuas ntsuas tswj kev ua haujlwm.
- Ntsuas lub sijhawm qhib thiab kaw; Lub sijhawm qhib rau 33kV VCBs nyob ntawm 30 txog 50 milliseconds.
- Txheeb xyuas cov kev taw qhia nkhaus uas tsim los txhawm rau txheeb xyuas cov khoom tsis sib xws, xws li qeeb, rov qab los, lossis qeeb zog.
5. Dynamic Contact Resistance (DCR) Test
- Qhov kev sim siab tshaj no saib xyuas qhov kev tiv thaiv tsis tu ncua thaum lub sijhawm ua haujlwm tawg.
- DCR nkhaus pab txheeb xyuas cov teeb meem xws li kev sib cuag bounce, lub sij hawm tsis sib xws, lossis kev tiv tauj ib nrab.
