Hauv qis-voltage fais fab faib tshuab,Circuit Court breakersua raws li "gatekeepers" rau kev nyab xeeb Circuit Court. Txawm li cas los xij, nquag mus ncig thaum lub sijhawm ua haujlwm tiag tiag feem ntau ua rau mob taub hau rau cov neeg ua haujlwm tu. Tripping tsis yog ib qho khoom siv tsis ua haujlwm xwb; nws feem ntau taw qhia rau plaub qhov laj thawj. Kev nthuav qhia cov laj thawj no yog qhov yuav tsum tau ua ua ntej rau kev kuaj xyuas qhov ua yuam kev thiab ua kom muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob.
overload yog feem ntau tripping mob
Qhov tseem ceeb ntawm overload yog cov nyhuv tshav kub. Thaum siab - lub hwj chim loads xws li cua txias thiab hluav taws xob lub rhaub dej yog txuas nrog lub voj voog ib txhij, qhov kev khiav hauj lwm tam sim no mus los yog tshaj qhovCircuit Court breakerntsuas qhov pib rau lub sijhawm ncua. Raws li Joule txoj cai, qhov nce ntawm tam sim no ua rau cov cua sov tsim nyob rau hauv kab kom nce quadratically. Lub bimetallic sawb nyob rau hauv lub Circuit Court breaker khoov thiab deforms vim tshav kub, triggering tripping thaum lub chaw ua hauj lwm pib mus txog. Nws yog ib qho tsim nyog sau cia tias cov cables nyias nyias lossis kev sib txuas xoob ntawm cov terminals ua rau muaj kev sib cuag zoo. Qhov tshwm sim hauv cheeb tsam kub kub ntxiv exacerbates tshav kub tsub zuj zuj, ua rau lubCircuit Court breakermus txawv tebchaws txawm tias tag nrho lub hwj chim tsis tshaj.
luv- Circuit Court txhaum yog qhov ua rau puas tsuaj ntau tshaj plaws
Thaum ib theem tus neeg xyuas pib nyob rau hauv kev sib cuag ncaj qha nrog tus neeg xyuas pib nruab nrab, los yog thaum lub sij hawm tus neeg xyuas pib luv luv -circuited rau hauv av, lub Circuit Court impedance tam sim ntawd zero, thiab luv luv - Circuit Court tam sim no muaj peev xwm ncav cuag kaum npaug ntawm qhov ntsuas tam sim no. Nyob rau lub sijhawm no, lub tshuab hluav taws xob mus ncig hauv lub tshuab hluav taws xob yuav ua rau tam sim ntawd, ua tiav "zero- ncua" instantaneous tripping. Cov kab hluav taws xob luv luv feem ntau tshwm sim los ntawm kev puas tsuaj rau cov txheej txheej rwb thaiv tsev ntawm cov kab uas tshwm sim los ntawm kev quab yuam sab nraud, lossis kev puas tsuaj ntawm cov khoom siv hluav taws xob sab hauv (xws li capacitors thiab fais fab transistors). Cov kev ua txhaum no feem ntau nrog rau cov yam ntxwv pom tseeb xws li kub hnyiab tsw thiab haus luam yeeb. Thaum lub sij hawm daws teeb meem, tag nrho cov loads yuav tsum raug txiav ua ntej, thiab tom qab ntawd qhov kev ua txhaum yuav tsum tau nyob los ntawm kev ntsuas qhov ntsuas hluav taws xob segmented.
leakage tam sim no tripping feem ntau misdiagnosed raws li ib tug luv luv Circuit Court
Circuit Court breakersnrog rau kev tiv thaiv tam sim no (RCBO) muaj ib qho ua tau -hauv xoom- ntu tam sim no transformer los saib xyuas cov vector sum ntawm tus neeg xyuas pib theem thiab nruab nrab tus neeg xyuas pib. Thaum lub rwb thaiv tsev ntawm cov kab los yog cov khoom muaj hnub nyoog los yog damp, ua rau qee qhov tam sim no los ntawm txoj kev hauv av, cov vector sum tsis yog xoom. Thaum cov seem tam sim no tshaj qhov teeb tsa kev ua haujlwm (feem ntau yog 30mA hauv cov ntawv thov hauv tsev, thiab 30mA-300mA hauv cov ntawv thov kev lag luam), qhov seem tiv thaiv tam sim no ua rau kev mus ncig hauv milliseconds. Cov yam ntxwv ntawm hom kev ua txhaum no yog: tam sim ntawd tripping tom qab kaw, thiab lub pob pib dua (qhov taw qhia tam sim no) tshwm sim, uas yog qhov txawv ntawm tus cwj pwm ntawm overload lossis luv luv Circuit Court.
qhov xwm txheej ntawm cov cuab yeej siv nws tus kheej thiab ib puag ncig cuam tshuam yuav tsum tsis txhob ignored
Tom qab rov qab siab dua - tam sim no cuam tshuam, kev sib cuag yaig ntawm lub Circuit Court breaker ua rau muaj kev tiv thaiv ntau ntxiv, ua rau qhov kub thiab txias ntxiv nyob rau hauv ib txwm load thiab ua rau thermal tripping malfunctions. Tsis tas li ntawd, nyob rau hauv siab - kub thiab siab - qhov chaw av noo, parameter drift ntawm cov khoom siv hluav taws xob los yog muaj zog electromagnetic cuam tshuam nrog cov seem tam sim no tshawb xyuas Circuit Court kuj yuav ua rau tsis yog -faulty tripping.
Nyob rau hauv cov ntsiab lus, kev daws teeb meem tripping teeb meem yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "sab nraud thawj, sab hauv thib ob; yooj yim thawj, complex thib ob." Ua ntej, disconnect tag nrho cov loads thiab kuaj fais fab rov qab. Yog tias nws tseem mus ncig, tsom mus rau kev txheeb xyuas kab hluav taws xob thiabluv luv Circuit Court; yog hais tias nws mus ncig hauv qab load, xam lub hwj chim thiab hlau txoj kab uas hla sib piv. Qhov tseeb nrhiav qhov laj thawj yog qhov tseem ceeb rau kev tshem tawm cov kev phom sij zais ntawm qhov chaw thiab ua kom muaj kev ruaj ntseg ntev - lub sij hawm system.
