Hluav taws xob Circuit Court breakerFeem ntau yog tsim los ntawm xoom sequence tam sim no transformer, hluav taws xob tivthaiv pawg thawj coj saib, tso tawm tawm thiab Circuit Court breaker nrog overload thiab luv-circuit tiv thaiv.Kev tiv thaiv cov dej xau ntawm cov hluav taws xob hluav taws xob hluav taws xob yog tsim los ntawm xoom ntu tam sim no transformer (sensing part), kev khiav hauj lwm xws li (tswj ib feem) thiab hluav taws xob tso tawm (ua haujlwm thiab ua tiav).Tag nrho cov theem thiab xoom kab ntawm kev tiv thaiv lub ntsiab Circuit Court dhau los ntawm cov tub ntxhais hlau ntawm xoom kab ke tam sim no transformer los ua thawj sab ntawm xoom sequence tam sim no transformer.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov hluav taws xob hluav taws xob tuaj yeem nkag siab zoo li:hluav taws xob Circuit Court breakertsis tuaj yeem tiv thaiv ob-theem hluav taws xob poob siab uas tiv tauj ob theem tib lub sijhawm.Cov hauv qab no yog piav qhia:
Nyob rau hauv daim duab, l yog electromagnet kauj, uas tuaj yeem tsav lub riam hloov K1 kom txiav tawm hauv cov ntaub ntawv xau.Txhua tus choj caj npab txuas nrog hauv cov koob nrog ob 1N4007 txhawm rau txhim kho qhov tiv taus hluav taws xob.Qhov tseem ceeb ntawm kev ua haujlwm ntawm R3 thiab R4 yog qhov loj heev, yog li thaum K1 raug kaw, qhov tam sim no ntws los ntawm L yog me me, uas tsis txaus ua rau qhov hloov K1 qhib.R3 thiab R4 yog qhov sib npaug ntawm qhov sib npaug ntawm cov thyristors T1 thiab T2, uas tuaj yeem txo qhov hluav taws xob tiv thaiv cov cai ntawm thyristors.K2 yog lub pob xeem, uas ua lub luag haujlwm ntawm simulating to.Nias lub pob xeem K2 thiab K2 txuas nrog, uas yog sib npaug ntawm cov xau ntawm cov kab nyob sab nraud rau lub ntiaj teb.Nyob rau hauv txoj kev no, cov vector sum ntawm tam sim no ntawm peb-theem fais fab kab thiab xoom kab dhau los ntawm lub nplhaib sib nqus tsis yog xoom, thiab muaj qhov induced voltage tso tawm ntawm ob qho tag nrho a thiab B ntawm qhov ntsuas coil ntawm lub nplhaib sib nqus. , uas tam sim ntawd ua rau T2 conduction.Txij li thaum C2 raug them nrog qee qhov hluav taws xob ua ntej, tom qab T2 tau qhib, C2 yuav tso tawm los ntawm R6, R5 thiab T2 los tsim hluav taws xob ntawm R5 thiab ua rau T1 tig rau.Tom qab T1 thiab T2 tau qhib, qhov tam sim no ntws los ntawm L nce zoo heev, yog li ntawd lub tshuab hluav taws xob ua haujlwm thiab tus tsav hloov K1 raug txiav.Lub luag haujlwm ntawm lub pob xeem yog los xyuas seb qhov haujlwm ntawm lub cuab yeej puas zoo li qub thaum twg los tau.Lub hauv paus ntsiab lus ntawm electromagnet ua los ntawm hluav taws xob to ntawm cov khoom siv hluav taws xob yog tib yam.R1 yog varistor rau kev tiv thaiv overvoltage.Qhov no yeej yog qhov tseem ceeb tshaj plaws ntawm kev tiv thaiv kev tiv thaiv hauv kev ua haujlwm ntawm kev xau Circuit Court breaker.
Thaum kawg, piav luv luv piav qhia txog lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab qee yam kev siv ntawm cov khoom siv hluav taws xob hauv tsev.Raws li cov cuab yeej siv hluav taws xob muaj kev nyab xeeb zoo,hluav taws xob Circuit Court breakertau siv dav thiab ua lub luag haujlwm tseem ceeb.Raws li kev tshawb fawb kev kho mob, thaum tib neeg lub cev raug rau 50Hz alternating tam sim no thiab hluav taws xob tam sim no yog 30mA los yog tsawg dua, nws muaj peev xwm tiv taus ob peb feeb.Qhov no txhais tau tias muaj kev nyab xeeb tam sim no ntawm tib neeg hluav taws xob poob siab thiab muab lub hauv paus kev tshawb fawb rau kev tsim thiab kev xaiv cov khoom siv tiv thaiv cov dej xau.Yog li ntawd, cov hluav taws xob hluav taws xob hluav taws xob tau teeb tsa hauv lub zog hluav taws xob uas cov khoom siv txawb thiab cov khoom siv hauv cov chaw ntub dej.Nws yog ib qho kev ntsuas zoo los tiv thaiv kev sib cuag tsis ncaj thiab hluav taws xob poob siab.Nyob rau hauv lub teb chaws tus qauv, nws yog tseeb hais tias "tshwj tsis yog rau lub qhov hluav taws xob cua txias lub qhov hluav taws xob, lwm lub hwj chim qhov hluav taws xob circuits yuav tsum tau nruab nrog cov khoom tiv thaiv to".Cov dej xau tam sim no yog 30mA thiab lub sijhawm ua haujlwm yog 0.1s.Kuv xav tias cov no tseem ceeb heev rau peb lub neej niaj hnub thiab tsim nyog peb mloog.
Schematic daim duab ntawm kev ua hauj lwm hauv paus ntsiab lus ntawm leakage protector ntawm peb-theem plaub hlau fais fab mov system.TA yog xoom ntu tam sim no transformer, GF yog lub ntsiab hloov, thiab TL yog shunt tso coil ntawm lub ntsiab hloov.
Raws li cov xwm txheej uas cov kev tiv thaiv Circuit Court ua haujlwm ib txwm tsis muaj hluav taws xob los yog hluav taws xob poob siab, raws li Kirchhoff txoj cai, qhov sib npaug ntawm cov phasors tam sim no ntawm thawj sab ntawm TA yog sib npaug rau xoom, uas yog, nyob rau hauv txoj kev no, lub thib ob sab ntawm TA ua. tsis tsim induced electromotive quab yuam, lub leakage protector tsis ua, thiab lub kaw lus tswj lub cev muaj zog mov.
Thaum cov dej xau tshwm sim hauv qhov kev tiv thaiv hluav taws xob lossis ib tus neeg tau txais hluav taws xob poob siab, vim tias muaj qhov ntws tawm tam sim no, phasor sum ntawm txhua theem tam sim no dhau los ntawm thawj sab ntawm TA tsis sib npaug li xoom, ua rau cov xau tam sim no IK.
Alternating magnetic flux tshwm nyob rau hauv lub hauv paus.Nyob rau hauv qhov kev txiav txim ntawm alternating magnetic flux, lub induced electromotive quab yuam yog generated nyob rau hauv lub kauj ntawm ob sab ntawm TL.cov teeb liab xau no tau ua tiav thiab muab piv los ntawm qhov txuas nruab nrab.Thaum nws ncav cuag tus nqi predetermined, lub kauj TL ntawm lub shunt tso tawm ntawm lub ntsiab hloov yog energized, lub ntsiab hloov GF yog tsav mus rau mus txawv tebchaws, thiab txhaum Circuit Court raug txiav tawm, thiaj li mus paub txog kev tiv thaiv.
