Kufunika kwa Ma RCD amtundu wa B mu Ntchito Zamakono Zamagetsi: Kuwonetsetsa Kuti Chitetezo M'mabwalo a AC ndi DC
Zida Zotsalira Zakale za Type B (RCDs)ndi zida zapadera zotetezera zomwe zimathandiza kupewa kugwedezeka kwa magetsi ndi moto pamakina omwe amagwiritsa ntchito Direct current (DC) kapena okhala ndi mafunde amagetsi osakhazikika. Mosiyana ndi ma RCD anthawi zonse omwe amagwira ntchito ndi ma alternating current (AC), Mitundu ya B RCD imatha kuzindikira ndikuyimitsa zolakwika m'mabwalo onse a AC ndi DC. Izi zimawapangitsa kukhala ofunikira kwambiri pamagetsi atsopano monga malo opangira magetsi agalimoto, ma solar, ma turbines amphepo, ndi zida zina zomwe zimagwiritsa ntchito magetsi a DC kapena mafunde amagetsi osakhazikika.
Ma RCD amtundu wa B amapereka chitetezo chabwino komanso chitetezo m'makina amakono amagetsi pomwe mafunde amagetsi a DC ndi omwe sali okhazikika. Amapangidwa kuti azidzimitsa magetsi pokhapokha ataona kusalinganika kapena vuto, kuletsa zochitika zomwe zingakhale zoopsa. Pamene kufunikira kwa machitidwe a mphamvu zongowonjezwdwa ndi magalimoto amagetsi kukukulirakulira, ma RCD amtundu wa B akhala ofunikira pakuwonetsetsa kuti matekinoloje atsopanowa ali otetezeka. Amathandiza kupewa kugunda kwa magetsi, moto, ndi kuwonongeka kwa zida zovutirapo pozindikira mwachangu ndikuyimitsa zolakwika zilizonse pamagetsi. Ponseponse, ma RCD amtundu wa B ndikupita patsogolo kofunikira pachitetezo chamagetsi, kuthandiza kuti anthu ndi katundu akhale otetezeka padziko lapansi pogwiritsa ntchito mphamvu za DC komanso mafunde amagetsi omwe siawiri.
Makhalidwe a JCRB2-100 Mtundu B RCDs
Ma JCRB2-100 Type B RCDs ndi zida zapamwamba zotetezera magetsi zomwe zimapangidwira kuti zipereke chitetezo chokwanira ku mitundu yosiyanasiyana ya zolakwika zamakina amakono. Zofunikira zawo zazikulu ndi izi:
Kumverera kwapaulendo: 30mA
Kukhudzika kwamphamvu kwa 30mA pa JCRB2-100 Type B RCDs kumatanthauza kuti chipangizocho chidzazimitsa magetsi ngati chitha kuzindikira kutulutsa kwamagetsi kwa 30 milliamp (mA) kapena kupitilira apo. Kukhudzidwa kumeneku ndikofunikira pakuwonetsetsa chitetezo chambiri kuzinthu zamagetsi zomwe zitha kuchitika kapena moto womwe umabwera chifukwa cha kuwonongeka kwa nthaka kapena kutayikira kwamadzi. Kutayikira kwa 30mA kapena kupitilira apo kumatha kukhala koopsa kwambiri, komwe kungayambitse kuvulala koopsa kapena kufa ngati sikunatsatidwe. Popunthwa pamlingo wotsika kwambiri wotayikira, JCRB2-100 imathandiza kupewa zinthu zowopsa ngati izi kuti zisachitike, kudula mphamvu mwachangu chisanadze vutolo.
2-Pole / Gawo Limodzi
Ma JCRB2-100 Type B RCDs adapangidwa ngati zida za 2-pole, zomwe zikutanthauza kuti amapangidwira kuti azigwiritsidwa ntchito pamagetsi agawo limodzi. Machitidwe a gawo limodzi amapezeka kawirikawiri m'nyumba zogona, maofesi ang'onoang'ono, ndi nyumba zazing'ono zamalonda. M'makonzedwe awa, mphamvu ya gawo limodzi imagwiritsidwa ntchito poyatsira magetsi, zida zamagetsi, ndi zina zazing'ono zamagetsi. Kukonzekera kwa 2-pole kwa JCRB2-100 kumapangitsa kuti iziyang'anira ndi kuteteza onse omwe ali ndi moyo komanso osalowerera ndale mu gawo limodzi, kuonetsetsa chitetezo chokwanira ku zolakwika zomwe zingachitike pa mzere uliwonse. Izi zimapangitsa chipangizochi kukhala choyenera kuteteza kuyika kwa gawo limodzi, komwe kumakhala kofala m'malo ambiri atsiku ndi tsiku.
Mayeso apano: 63A
Ma JCRB2-100 Type B RCDs ali ndi ma 63 amps (A). Kuyeza uku kukuwonetsa kuchuluka kwa magetsi omwe chipangizocho chingathe kugwira bwino pakagwiritsidwe ntchito kabwinobwino popanda kupunthwa kapena kulemedwa. Mwanjira ina, JCRB2-100 itha kugwiritsidwa ntchito kuteteza mabwalo amagetsi okhala ndi katundu mpaka 63 amps. Chiwerengero chamakonochi chimapangitsa chipangizochi kukhala choyenera pa ntchito zosiyanasiyana zogona komanso zopepuka zamalonda, kumene katundu wamagetsi amagwera mkati mwamtunduwu. Komabe, ndikofunikira kudziwa kuti ngakhale pakadali pano ili mkati mwa 63A, JCRB2-100 idzayendabe ngati itazindikira kutayikira kwa 30mA kapena kupitilira apo, chifukwa uku ndi kukhudzika kwake kwachitetezo chachitetezo.
Mphamvu yamagetsi: 230V AC
Ma JCRB2-100 Type B RCDs ali ndi voteji ya 230V AC. Izi zikutanthauza kuti adapangidwa kuti azigwiritsidwa ntchito pamakina amagetsi omwe amagwira ntchito pamagetsi amtundu wa 230 volts alternating current (AC). Kuvotera kumeneku ndikofala m'malo ambiri okhalamo komanso opepuka amalonda, kupangitsa JCRB2-100 kukhala yoyenera kugwiritsidwa ntchito m'malo awa. Ndikofunika kudziwa kuti chipangizochi sichiyenera kugwiritsidwa ntchito pamakina amagetsi okhala ndi ma voltages apamwamba kuposa mphamvu yake, chifukwa izi zitha kuwononga chipangizocho kapena kusokoneza mphamvu yake yogwira ntchito bwino. Potsatira ma voteji a 230V AC, ogwiritsa ntchito amatha kuonetsetsa kuti JCRB2-100 igwira ntchito motetezeka komanso moyenera mkati mwazomwe akufuna.
Kuthekera Kwanthawi Yaifupi: 10kA
Mphamvu yaposachedwa ya JCRB2-100 Type B RCDs ndi 10 kiloamps (kA). Kuyeza uku kukutanthauza kuchuluka kwa nthawi yayitali yomwe chipangizocho chingapirire chisanawonongeke kapena kulephera. Mafunde afupipafupi amatha kuchitika mumagetsi chifukwa cha zolakwika kapena zovuta, ndipo amatha kukhala okwera kwambiri komanso owononga. Pokhala ndi mphamvu yanthawi yochepa ya 10kA, JCRB2-100 idapangidwa kuti ikhalebe yogwira ntchito ndikupereka chitetezo ngakhale pakakhala vuto lalikulu lachidule, mpaka 10,000 amps. Mbaliyi imatsimikizira kuti chipangizochi chikhoza kuteteza bwino magetsi ndi zigawo zake pakachitika zolakwika zapamwamba zoterezi.
Mulingo wa Chitetezo cha IP20
Ma RCD a JCRB2-100 Type B ali ndi chitetezo cha IP20, chomwe chimayimira "Ingress Protection" 20. Chiwerengerochi chimasonyeza kuti chipangizochi chimatetezedwa ku zinthu zolimba zazikulu kuposa mamilimita 12.5 kukula kwake, monga zala kapena zida. Komabe, sizipereka chitetezo kumadzi kapena zakumwa zina. Chotsatira chake, JCRB2-100 siyoyenera kugwiritsidwa ntchito panja kapena kuyika m'malo omwe amatha kukhala ndi chinyezi kapena zakumwa popanda chitetezo chowonjezera. Kuti mugwiritse ntchito chipangizocho panja kapena m'malo onyowa, chiyenera kuyikidwa mkati mwa mpanda woyenera womwe umapereka chitetezo chofunikira kumadzi, fumbi ndi zinthu zina zachilengedwe.
Kugwirizana ndi IEC/EN 62423 ndi IEC/EN 61008-1 Miyezo
Ma JCRB2-100 Type B RCDs adapangidwa ndikupangidwa motsatira mfundo ziwiri zofunika zapadziko lonse lapansi: IEC/EN 62423 ndi IEC/EN 61008-1. Miyezo iyi imatanthauzira zofunikira ndi kuyesa kwa Residual Current Devices (RCDs) zomwe zimagwiritsidwa ntchito poyika magetsi otsika. Kutsatira mfundozi kumatsimikizira kuti JCRB2-100 ikukumana ndi chitetezo chokhazikika, machitidwe, ndi malangizo abwino, kutsimikizira chitetezo chokhazikika ndi kudalirika. Potsatira mfundo zodziwika bwinozi, ogwiritsa ntchito akhoza kukhala ndi chidaliro kuti chipangizochi chimagwira ntchito monga momwe amafunira ndikupereka chitetezo chofunikira pakuwonongeka kwamagetsi ndi zoopsa.
Mapeto
TheJCRB2-100 Mtundu B RCDsndi zida zachitetezo zapamwamba zopangidwira kuti zipereke chitetezo chokwanira pamakina amakono amagetsi. Ndi zinthu monga 30mA yovutirapo kwambiri yodutsa, kukwanira kwa magawo amodzi, 63A pano, ndi 230V AC voteji, amapereka chitetezo chodalirika pazovuta zamagetsi. Kuonjezera apo, mphamvu zawo za 10kA zachidule zomwe zilipo, chitetezo cha IP20 (chofuna mpanda woyenera kuti chigwiritsidwe ntchito panja), komanso kutsata mfundo za IEC/EN zimatsimikizira kugwira ntchito mwamphamvu komanso kutsata malamulo amakampani. Ponseponse, ma JCRB2-100 Type B RCDs amapereka chitetezo chowonjezereka komanso kudalirika, kuwapanga kukhala gawo lofunikira pakuyika kwamagetsi kunyumba, malonda, ndi mafakitale.
FAQ
1.Kodi Type B RCD ndi chiyani?
Ma RCD amtundu wa B asasokonezedwe ndi mtundu wa B MCBs kapena ma RCBO omwe amawonekera pamasaka ambiri.
Mitundu ya B RCD ndi yosiyana kotheratu, komabe, mwatsoka chilembo chomwecho chagwiritsidwa ntchito chomwe chingakhale chosocheretsa. Pali Mtundu B womwe ndi mawonekedwe amafuta mu MCB/RCBO ndi Mtundu B wofotokozera mawonekedwe a maginito mu RCCB /RCD. Izi zikutanthauza kuti mudzapeza zinthu monga ma RCBO okhala ndi mikhalidwe iwiri, yomwe ndi maginito a RCBO ndi chinthu chotenthetsera (izi zitha kukhala Mtundu wa AC kapena A maginito ndi Mtundu B kapena C wotentha RCBO).
2.Kodi Type B RCDs imagwira ntchito bwanji?
Ma RCD a Type B nthawi zambiri amapangidwa ndi makina awiri otsalira omwe amazindikira. Yoyamba imagwiritsa ntchito ukadaulo wa 'fluxgate' kuti RCD izindikire yosalala ya DC yapano. Yachiwiri imagwiritsa ntchito ukadaulo wofanana ndi Type AC ndi Type A RCDs, womwe ndi wodziyimira pawokha.
