Idivayisi yamanje eyinsalela , JCRB2-100 Uhlobo B

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.
