Relays yog siv los txheeb xyuas qhov tsis ua haujlwm hauv cov tshuab hluav taws xob thiab qhib kev tiv thaiv kev tiv thaiv kom tsis txhob muaj kev puas tsuaj rau cov khoom siv thiab kev phom sij rau cov neeg ua haujlwm. Cov kev tiv thaiv no muaj xws li kev sib tsoo Circuit Court breakers, qhib li qub, lossis suab tswb. Relays yog tsim los ua haujlwm sai thiab raug, kom txo tau lub sij hawm xav tau rau kev tiv thaiv kom muaj txiaj ntsig.
Txawm li cas los xij, yog tias cov relays tsis raug tswj xyuas kom zoo thiab kuaj, lawv tuaj yeem ua tsis tau zoo thiab ua haujlwm tsis zoo. Kev ua haujlwm tsis zoo ntawm cov relays tuaj yeem ua rau cov tshuab hluav taws xob muaj kev puas tsuaj thiab ua rau muaj kev pheej hmoo rau cov neeg ua haujlwm. Qhov no yog vim li cas kev tu ncua relay yog qhov tseem ceeb.
Kev saib xyuas zoo relay suav nrog ntau cov txheej txheem, suav nrog kev tu thiab tshuaj xyuas cov neeg sib cuag, kuaj xyuas cov kab txuas txuas, thiab ntsuas kev ua haujlwm thiab sijhawm. Ib qho kev ntsuam xyuas tseem ceeb tshaj plaws hauv kev saib xyuas relay yog Secondary Current Injection Testing.
Secondary Current Injection Testing yog ib txoj hauv kev ntawm hluav taws xob simulating qhov teeb meem txhaum cai, txhawm rau txheeb xyuas qhov kev tiv thaiv relays yuav ua haujlwm raug raws li qhov ua txhaum. Qhov kev sim simulates cov xwm txheej hauv qab uas lub relay yuav tsum ua haujlwm, thiab ntsuas lub sijhawm nws siv rau lub relay qhib, qhov tseeb ntawm nws txoj haujlwm, thiab kev ntseeg siab ntawm relay cov lus teb.
Kev ntsuam xyuas yuav tsum tau txhaj ib qho tam sim no rau hauv lub relay hauv kev tswj hwm, thiab saib xyuas cov lus teb ntawm relay rau qhov simulated txhaum. Cov txiaj ntsig ntawm qhov kev ntsuam xyuas muab cov lus qhia muaj txiaj ntsig ntawm kev ua haujlwm ntawm relay, thiab txhua qhov kev hloov kho uas tsim nyog tuaj yeem ua tau raws li cov txiaj ntsig. Nws tuaj yeem ua tau los ntawm kev tiv thaiv relay tester. Muaj ntau ntau hom qauv ntawm relay tester nrog 3 theem lossis 6 theem. HUAYI hluav taws xob Dav dav mloog cov kev xav ntawm cov neeg siv, sau cov ntsiab lus zoo thiab qhov tsis zoo ntawm cov khoom zoo sib xws hauv Suav teb, thiab siv tag nrho cov cuab yeej siv niaj hnub niaj hnub microelectronics thiab cov cuab yeej kom paub txog qhov tshiab miniaturized microcomputer relay tiv thaiv tester. Tsis yog tsuas yog cov tsoos relay thiab cov cuab yeej tiv thaiv tuaj yeem kuaj tau, tab sis kuj muaj ntau yam kev ntsuas kev tiv thaiv lub computer niaj hnub, tshwj xeeb tshaj yog rau transformer sib txawv zog tiv thaiv thiab cov khoom pov tseg tus kheej, qhov kev sim no yooj yim dua thiab zoo meej.
