8 Yam Koj Yuav Tsum Paub Txog Kev Tiv Thaiv Relay

01 Dab tsi yog qhov zoo ntawm kev siv overcompensated ua haujlwm rau nruab nrab taw tes ntawm arcing coil grounding system?

Qhov nruab nrab taw tes los ntawm arcing coil grounding system siv kev ua haujlwm tshaj nyiaj tau los muaj qhov zoo hauv qab no:
 

(1) vim yog over-compensation ntws los ntawm lub grounding point yog inductive tam sim no, arc quenching txhaum theem voltage rov qab ceev yog qeeb, yog li ntawd lub grounding arc tsis yooj yim rau re-ignite.
 

(2) kev siv cov nyiaj overcompensation, lub kaw lus zaus txo tsuas yog ua rau overcompensation degree nce ib ntus, uas tsis muaj teeb meem hauv kev ua haujlwm li qub.
 

(3) nrog rau kev txhim kho txuas ntxiv thiab nthuav dav ntawm lub zog hluav taws xob, daim phiaj hluav taws xob hauv av nce ntxiv, yog tias siv cov nyiaj them poob haujlwm, tus thawj arc coil tuaj yeem siv txuas ntxiv mus rau lub sijhawm, feem ntau los ntawm overcompensation mus rau hauv kev them nyiaj poob haujlwm; tab sis yog hais tias tus thawj under-compensation ntawm lub hom ntawm kev ua hauj lwm, ces lub system yuav tsum tau tam sim ntawd nce nyob rau hauv kev loj hlob ntawm cov nyiaj them peev xwm.

02 Qhov kev tiv thaiv nyob ze yog dab tsi?

Nyob ze kev tiv thaiv kev tiv thaiv yog nruab ob txheej kev tiv thaiv ntawm tib lub hluav taws xob tiv thaiv, thaum ib txheej tiv thaiv tsis kam ua haujlwm, lwm cov txheej txheem tiv thaiv kev ua haujlwm hauv kev mus ncig. Thaum lub Circuit Court breaker tsis kam ua, kev tiv thaiv ua haujlwm nrog rau lub sijhawm txwv los ua lub tsheb npav txuas nrog Circuit Court breaker ntawm txhua lub zog xa mus rau kev mus ncig.
 

03 txhais li cas los ntawm rhiab heev ntawm cov khoom tiv thaiv relay?
 

04 Kev tiv thaiv tam sim no yog dab tsi?

Thaum ib qho luv luv Circuit Court tshwm sim ntawm txoj kab, qhov tam sim no ntws los ntawm txoj kab nce dheev, thaum tam sim no tshaj qhov teeb tsa tus nqi ntawm cov cuab yeej tiv thaiv thiab mus txog lub sijhawm teeb tsa thaum qhov kev tiv thaiv hauv kev mus ncig, cov tshuaj tiv thaiv tam sim no nce qhov chaw. ntawm qhov kev txiav txim ntawm cov cuab yeej tiv thaiv yog hu ua kev tiv thaiv tam sim no.

RDJB-1600K Relay Protection Test Set yog peb lub tuam txhab tau mloog cov neeg siv kev xav, sau cov ntsiab lus zoo thiab qhov tsis zoo ntawm cov khoom lag luam zoo sib xws nyob rau tam sim no, thiab siv cov khoom siv niaj hnub qib siab tshiab ntawm cov khoom siv tiv thaiv microcomputer relay tiv thaiv cov khoom siv raws li microelectronic technology. thiab cov khoom siv. Qhov loj me thiab qhov raug siab. Nws tsis tsuas yog muaj kev ua tau zoo tshaj plaws thiab kev ua haujlwm siab ntawm cov neeg ntsuas loj, tab sis kuj muaj qhov zoo ntawm compactness, saj zawg zog, kev ua haujlwm yooj yim, kev ntseeg siab, thiab lwm yam ntawm cov me me testers, thiab kev ua haujlwm siab-nqi piv. Nws yog ib qho cuab yeej zoo rau cov neeg ua haujlwm tiv thaiv relay

05 Dab tsi yog hu ua kev tiv thaiv tam sim no? Nws cov yam ntxwv yog dab tsi?

Qhov siab tshaj plaws luv luv-circuit tam sim no ntws los ntawm kev tiv thaiv thaum zam lub sab nraud luv luv-circuit ntawm cov tiv thaiv tiv thaiv yog teem los xyuas kom meej tias nws xaiv ua raws li kev tiv thaiv tam sim no yam tsis muaj sij hawm txwv, hu ua tam sim no breakage tiv thaiv.

Nws yog tus cwj pwm los ntawm: kev xaim yooj yim, txhim khu kev qha, thiab tshem tawm qhov txhaum sai, tab sis tsis tuaj yeem tiv thaiv tag nrho cov kab ntev, qhov kev tiv thaiv los ntawm kev hloov pauv hauv cov qauv kev ua haujlwm muaj kev cuam tshuam ntau dua.

06 Dab tsi yog hu ua lub sijhawm txwv kev tiv thaiv kev cuam tshuam tam sim no? Nws cov yam ntxwv yog dab tsi?

Raws li lub ntsiab lus tom ntej, qhov txuas ntxiv ntawm kev tiv thaiv kev cuam tshuam tam sim no yog kom tau txais kev tiv thaiv tam sim no nrog lub sijhawm luv luv, hu ua lub sijhawm txwv kev tiv thaiv kev cuam tshuam tam sim no.

07 Dab tsi yog lub sijhawm txwv kev tiv thaiv overcurrent? Dab tsi yog txhais los ntawm lub sijhawm txwv kev tiv thaiv overcurrent?

Txhawm rau kom paub txog qhov kev xaiv xaiv ntawm kev tiv thaiv overcurrent, lub sijhawm ua haujlwm ntawm txhua qhov kev tiv thaiv feem ntau tau teeb tsa raws li lub hauv paus ntsiab lus ntawm tus ntaiv. Ntawd yog, lub sijhawm ua haujlwm ntawm kev tiv thaiv nyob ib puag ncig, los ntawm kev thauj mus los ntawm cov kev taw qhia ntawm cov khoom siv hluav taws xob nce zuj zus, thiab lub sijhawm ua haujlwm ntawm txhua qhov kev tiv thaiv yog tas li, ywj pheej ntawm qhov loj ntawm qhov luv-circuit tam sim no. Kev tiv thaiv overcurrent nrog lub sijhawm ua haujlwm no yog hu ua lub sijhawm tiv thaiv overcurrent.

Txhais nrog www.DeepL.com/Translator (dawb version)

Inverse time overcurrent tiv thaiv yog hais txog lub sijhawm ua haujlwm nrog qhov luv-circuit tam sim no nce thiab cia li txo lub sijhawm ua haujlwm ntawm kev tiv thaiv. Lub sij hawm thim rov qab tiv thaiv overcurrent siv ntawm cov kab sib kis tuaj yeem tshem tawm qhov txhaum ntawm thawj qhov kawg ntawm cov kab tiv thaiv sai dua.

08 Dab tsi yog lub hauv paus ntsiab lus ntawm kev teeb tsa tam sim no ntawm lub sijhawm txwv kev tiv thaiv overcurrent?

(1) Qhov kev txiav txim tam sim no yuav tsum zam kom tsis txhob muaj qhov siab tshaj plaws tam sim no.

(2) Kev tiv thaiv sab saud thiab qis dua yuav tsum sib haum nrog kev ua haujlwm tam sim no thiab lub sijhawm txwv.

(3) Nyob rau hauv hom tsawg kawg nkaus ntawm kev ua haujlwm, qhov rhiab heev coefficient rau hlau ob-theem luv luv Circuit Court ntawm qhov kawg ntawm qhov chaw tiv thaiv yuav tsum tsis pub tsawg tshaj 1.5.
