Relays yog ib qho tseem ceeb ntawm txhua qhov hluav taws xob, muab kev tiv thaiv tseem ceeb tiv thaiv overloads, luv circuits, thiab av txhaum. Yog tias tsis muaj kev tiv thaiv zoo, cov kev ua txhaum no tuaj yeem nce mus rau qhov xwm txheej txaus ntshai uas tuaj yeem ua rau cov khoom puas tsuaj, cuam tshuam rau kev ua haujlwm, thiab ua rau raug mob. Yog li ntawd, nws yog ib qho tseem ceeb los xyuas kom meej tias cov relays ua haujlwm kom raug thiab ntseeg tau, uas yuav tsum tau kuaj xyuas thiab tu.
Ib qho ntawm cov txiaj ntsig zoo tshaj plaws ntawm kev ntsuam xyuas relay yog kev ntsuam xyuas kev txhaj tshuaj thib ob. Txoj kev no suav nrog kev txhaj tshuaj simulated tam sim no rau hauv lub relay kom paub tseeb tias nws teb tau zoo thiab nrawm rau qhov txhaum. Kev txhaj tshuaj thib ob tam sim no tuaj yeem pab txheeb xyuas cov kev cuam tshuam tsis raug, ceeb toom cov neeg siv rau cov teeb meem uas yuav tshwm sim, thiab xyuas kom meej tias lub kaw lus tiv thaiv tsis raug hluav taws xob.
Thaum ua qhov kev ntsuam xyuas kev txhaj tshuaj thib ob, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov khoom siv zoo relay test. Cov khoom siv no muaj tag nrho cov khoom tsim nyog rau kev kuaj kev nyab xeeb thiab raug, suav nrog qhov chaw txhaj tshuaj, tam sim no transformer, thiab chav tswj. Nrog rau cov khoom siv kuaj kom raug, cov neeg siv tuaj yeem ua tiav cov kev ntsuam xyuas ntawm ntau yam ntawm cov relays, nrog rau hauv av txhaum, overcurrent, directional, thiab deb relays.
Ntxiv nrog rau kev muab cov txiaj ntsig txhim khu kev qha, kev txhaj tshuaj thib ob tam sim no muaj ntau yam txiaj ntsig dua lwm txoj kev sim. Piv txwv li, nws tsis yog kev puas tsuaj thiab tsis tas yuav tsum muaj kev cuam tshuam ntawm relay los ntawm lub kaw lus, uas tuaj yeem txuag lub sijhawm thiab txo qis sijhawm. Tsis tas li ntawd, nws yog ib txoj hauv kev rov ua dua thiab cov qauv kev sim uas tuaj yeem siv los sib piv cov txiaj ntsig thoob qhov sib txawv relays thiab qhov chaw.
Relay Protection Tester yog ib qho cuab yeej tseem ceeb rau kev saib xyuas lub zog. Nws tso cai rau kev ntsuam xyuas qhov tseeb thiab txhim khu kev qha ntawm cov relays rau kev ua haujlwm zoo thiab ua kom muaj kev ua tau zoo ntawm lub zog tag nrho. Kev siv cov 3-theem relay tester thiab 6-theem relay tester tau dhau los ua qhov tseem ceeb hauv kev ntsuas hluav taws xob niaj hnub vim lawv muaj peev xwm ua tau zoo thiab muaj peev xwm los ntsuas cov txheej txheem tiv thaiv qib siab.
