JCRB2-100 Mtundu B RCDs

Ma RCD a JCRB2-100 amtundu wa B amapereka chitetezo ku mafunde otsalira olakwika / kutayikira kwapadziko lapansi pamapulogalamu a AC okhala ndi mawonekedwe apadera.

Ma RCD amtundu wa B amagwiritsidwa ntchito pomwe mafunde osalala komanso / kapena opumira a DC amatha kuchitika, ma waveform osakhala a sinusoidal alipo kapena ma frequency akulu kuposa 50Hz;mwachitsanzo, Kuchartsa Galimoto Yamagetsi, zida zina za 1-phase, micro generation kapena SSEGs (Small Scale Electricity Generators) monga ma sola ndi ma jenereta amphepo.

Chiyambi:

Type B RCDs (Zotsalira Zamakono Zamakono) ndi mtundu wa chipangizo chomwe chimagwiritsidwa ntchito poteteza magetsi.Amapangidwa kuti aziteteza ku zolakwika zonse za AC ndi DC, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza zomwe zimakhudzana ndi katundu wa DC monga magalimoto amagetsi, magetsi ongowonjezwdwa, ndi makina opanga mafakitale.Ma RCD amtundu wa B ndi ofunikira popereka chitetezo chokwanira pakuyika kwamagetsi kwamakono.

Ma RCD amtundu wa B amapereka chitetezo chokwanira kuposa zomwe ma RCD wamba angapereke.Ma RCD a Type A amapangidwa kuti aziyenda pakachitika vuto la AC, pomwe ma RCD a Type B amathanso kuzindikira magetsi otsalira a DC, kuwapangitsa kukhala oyenera kukulitsa magetsi.Izi ndizofunikira makamaka chifukwa kufunikira kwa magetsi osinthika komanso magalimoto amagetsi akupitilira kukula, ndikupanga zovuta zatsopano komanso zofunikira pachitetezo chamagetsi.

Chimodzi mwazabwino zazikulu zamtundu wa B RCDs ndikutha kupereka chitetezo pamaso pa katundu wa DC.Mwachitsanzo, magalimoto amagetsi amadalira pakali pano kuti ayendetsedwe, choncho milingo yoyenera yachitetezo iyenera kukhalapo kuti zitsimikizire chitetezo chagalimoto ndi zida zolipirira.Momwemonso, makina opangira mphamvu zongowonjezwdwa (monga ma solar panel) nthawi zambiri amagwira ntchito pamagetsi a DC, zomwe zimapangitsa mtundu wa B RCD kukhala chinthu chofunikira pakuyika uku.

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).

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.
