Kev soj ntsuam ntawm kev ua tsis tiav ntawm kev tiv thaiv relay
①Saturation txhaum ntawm tam sim no kev sib nrig sib inductance
Lub saturation ntawm tam sim no transformer muaj kev cuam tshuam loj heev rau lub hwj chim system relay tiv thaiv. Raws li lub davhlau ya nyob twg thauj khoom ntawm lub zog xa hluav taws xob txuas ntxiv mus, yog tias qhov luv luv tshwm sim, qhov luv luv tam sim no yuav loj heev. Yog tias lub kaw lus luv luv nyob ze ntawm thaj chaw cov khoom siv davhlau ya nyob twg, qhov tam sim no tuaj yeem ncav cuag lossis mus txog ntau dua 100 npaug ntawm qhov ntsuas tam sim no ntawm qhov tam sim no transformer. Nyob rau hauv cov ntaub ntawv ntawm ib tug luv luv Circuit Court, qhov loj dua tam sim no transformer yuam kev nce nrog rau qhov nce ntawm thawj short-circuit tam sim no ntau yam, thaum tam sim no ceev-tawg tiv thaiv txo qhov rhiab heev, nws yuav tiv thaiv qhov kev txiav txim. Thaum cov kab yog luv luv, vim hais tias tam sim no ntawm lub tam sim no transformer yog saturated, thiab lub thib ob tam sim no induced dua yog me me los yog ze rau xoom, nws tseem yuav ua rau lub overcurrent tiv thaiv ntaus ntawv tsis ua hauj lwm. Thaum cov kev tiv thaiv overcurrent ntawm lub qhov hluav taws xob kab ntawm lub hwj chim faib system tsis kam ua thiab inlet kab kev tiv thaiv ntawm lub hwj chim faib chaw nres tsheb yog qhib, tag nrho cov fais fab faib system yuav tawm ntawm lub hwj chim.

② Kev xaiv tsis raug ntawm cov cuab yeej tiv thaiv hloov pauv
Kev xaiv cov cuab yeej tiv thaiv kev hloov pauv yog ib txoj haujlwm tseem ceeb heev. Feem ntau ntawm hnub no' s fais fab kev faib tawm yog los tsim cov chaw hloov chaw nyob rau hauv high-load-intensive cheeb tsam, uas yog, hom ntawm fais fab mov thiab kis tau tus mob ntawm substation-hloov chaw nres tsheb-distribution transformer yog saws. Hauv switchyards uas tsis tau paub txog kev tiv thaiv relay automation, peb yuav tsum siv cov khoom siv thauj khoom lossis cov khoom siv relay ua ke nrog lawv ntau dua li cov khoom siv tiv thaiv hloov.
Muaj ntau Fuses, cov khoom lag luam npog tag nrho cov cheeb tsam ntawm lub zog tshiab tsheb (Pack, PDU, BDU, Hluav taws xob tswj, Lub cev muaj zog, MSD, Tsis tshua muaj hluav taws xob thaiv kab hluav taws xob), Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, Photovoltaic PV Hnub ci hlws ris lub thawv, photovoltaic inverter, UPS fais fab mov, 5G Kev sib txuas lus fais fab mov, BS UK plug, Hluav taws xob hauv tsev tswj vaj huam sib luag, teeb pom kev zoo tsav fais fab mov thiab lwm yam.
