JCRB2-100 Uhlobo B RCDs

I-JCRB2-100 Type B RCDs ihlinzeka ngokuvikeleka kuma-currents amaphutha ayinsalela / ukuvuza komhlaba ezinhlelweni zokunikezela nge-AC ezinezici ezithile ze-waveform.

Ama-RCD ohlobo lwe-B asetshenziswa lapho amagagasi asele e-DC abushelelezi kanye/noma aphehlayo angenzeka khona, amagagasi angewona awe-sinusoidal akhona noma amaza angaphezu kuka-50Hz;isibonelo, Ukushaja Imoto Kagesi, amadivaysi athile esigaba esi-1, i-micro generation noma ama-SSEG (Ama-Small Scale Electricity Generators) njengamaphaneli elanga namajeneretha omoya.

Isingeniso:

Uhlobo B RCDs (Residual Current Devices) awuhlobo lwedivayisi esetshenziselwa ukuphepha kukagesi.Idizayinelwe ukuhlinzeka ngokuvikeleka kuwo womabili amaphutha e-AC ne-DC, okuyenza ifanelekele uhla olubanzi lwezinhlelo zokusebenza, okuhlanganisa lezo ezifaka imithwalo ebucayi ye-DC njengezimoto zikagesi, amasistimu avuselelekayo avuselelekayo, nemishini yezimboni.Ama-RCD ohlobo B abalulekile ekunikezeni ukuvikeleka okuphelele ekufakweni kukagesi kwesimanje.

Ama-RCD ohlobo lwe-B ahlinzeka ngezinga lokuphepha elingaphezu kwalokho okungahlinzekwa ngama-RCD avamile.Ama-RCD ohlobo A aklanyelwe ukuhamba uma kwenzeka iphutha le-AC, kuyilapho ama-RCD oHlobo lwe-B angakwazi futhi ukubona i-DC residual current, awenze afanelekele ukukhulisa izinhlelo zikagesi.Lokhu kubaluleke kakhulu njengoba isidingo sezinhlelo zamandla avuselelekayo kanye nezimoto zikagesi ziqhubeka nokukhula, kudala izinselele ezintsha kanye nezidingo zokuphepha zikagesi.

Enye yezinzuzo eziyinhloko zama-RCD oHlobo lwe-B yikhono lawo lokunikeza isivikelo lapho kukhona imithwalo ebucayi ye-DC.Isibonelo, izimoto zikagesi zithembele kumandla aqondile ukuze ziqhube, ngakho kufanele kube khona amazinga afanele okuvikela ukuze kuqinisekiswe ukuphepha kwemoto nengqalasizinda eshajayo.Ngokufanayo, izinhlelo zamandla avuselelekayo (njengamaphaneli elanga) ngokuvamile zisebenza ngamandla e-DC, okwenza ama-RCD oHlobo lwe-B abe ingxenye ebalulekile kulokhu kufakwa.

Luyini Uhlobo B RCD?

Ama-RCD ohlobo B akumele adidaniswe nohlobo lwe-B MCB noma ama-RCBO avela ekusesheni okuningi kwewebhu.

Ama-RCD oHlobo lwe-B ahluke ngokuphelele, nokho, ngeshwa uhlamvu olufanayo lusetshenzisiwe olungase ludukise.Kukhona Uhlobo B oluwuphawu olushisayo ku-MCB/RCBO kanye Nohlobo B oluchaza izici kazibuthe ku-RCCB /RCD.Lokhu kusho ukuthi uzothola imikhiqizo efana nama-RCBO anezici ezimbili, okuyisici sikazibuthe se-RCBO kanye nesici esishisayo (lokhu kungaba Uhlobo AC noma A kazibuthe kanye Nohlobo B noma C olushisayo lwe-RCBO).

Asebenza kanjani ama-RCD ohlobo lwe-B?

Ama-RCD ohlobo lwe-B ngokuvamile aklanywa ngamasistimu amabili asele okutholwayo.Eyokuqala isebenzisa ubuchwepheshe be-'fluxgate' ukuze i-RCD ikwazi ukubona i-DC yamanje ebushelelezi.Eyesibili isebenzisa ubuchwepheshe obufana nohlobo lwe-AC kanye nohlobo A RCDs, oluzimele nge-voltage.
