JCRB2-100 Uhlobo B RCDs

I-JCRB2-100 Uhlobo lwe-RCDs lwe-B lubonelela ngokhuseleko kwimisinga yempazamo eseleyo / ukuvuza komhlaba kwizicelo zobonelelo lwe-AC ezineempawu ezithile zamaza.

Ii-RCD zodidi lwe-B zisetyenziswa apho i-DC egudileyo kunye/okanye i-pulsating i-residual currents ye-DC inokwenzeka, ii-non-sinusoidal waveforms zikhona okanye ii-frequencies ezinkulu kune-50Hz;umzekelo, ukuTshaja iSithuthi soMbane, izixhobo ezithile zesigaba esi-1, ukuveliswa kwemicro okanye ii-SSEG (Iijenereyitha zoMbane eziNcinci) ezifana neepaneli zelanga kunye neejenereyitha zomoya.

Iinkcukacha zeMveliso

Intshayelelo:

Ii-RCD zodidi lwe-B (iZixhobo eziSisalelayo zangoku) luhlobo lwesixhobo esisetyenziselwa ukhuseleko lombane.Ziyilelwe ukubonelela ngokhuseleko kuzo zombini iimpazamo ze-AC kunye ne-DC, zizenza zilungele uluhlu olubanzi lwezicelo, kubandakanywa nezo zibandakanya imithwalo e-DC enovakalelo efana nezithuthi zombane, iinkqubo zamandla avuselelekayo, kunye noomatshini bemizi-mveliso.Ii-RCD zodidi lwe-B zibalulekile ekuboneleleni ngokhuseleko olubanzi kufakelo lombane lwanamhlanje.

Ii-RCD zodidi lwe-B zibonelela ngenqanaba lokhuseleko ngaphaya kwee-RCD eziqhelekileyo ezinokubonelela.Ii-RCD zodidi lwe-A ziyilelwe ukuba zihambe xa kukho impazamo ye-AC, ngelixa ii-RCD zodidi lwe-B zikwazi ukubona i-DC eshiyekileyo, izenza zilungele usetyenziso lombane olukhulayo.Oku kubaluleke ngakumbi njengoko imfuno yeenkqubo zamandla avuselelekayo kunye nezithuthi zombane ziqhubeka zikhula, zidala imingeni emitsha kunye neemfuno zokhuseleko lombane.

Enye yeenzuzo eziphambili zoHlobo lwe-RCDs kukukwazi ukubonelela ngokhuseleko phambi kwemithwalo ebuthathaka ye-DC.Ngokomzekelo, izithuthi zombane zixhomekeke kumbane othe ngqo wokuqhubela phambili, ngoko ke amanqanaba afanelekileyo okukhusela kufuneka abe khona ukuze kuqinisekiswe ukhuseleko lwesithuthi kunye neziseko zokutshaja.Ngokunjalo, iinkqubo zamandla ahlaziyekayo (ezifana neepaneli zelanga) zihlala zisebenza kumbane we-DC, zenza udidi lwe-RCD lwe-RCD lube yinxalenye ebalulekileyo kolu fakelo.

Yintoni uhlobo lwe-RCD ye-B?

Ii-RCD zodidi lwe-B kufuneka zingabhidaniswa noHlobo lwe-MCBs okanye ii-RCBOs ezibonakala kukhangelo oluninzi lwewebhu.

Ii-RCD zoHlobo lwe-B zahluke ngokupheleleyo, nangona kunjalo, ngelishwa kwaloo leta inye iye yasetyenziswa enokulahlekisa.Kukho udidi lwe-B oluluphawu lwe-thermal kwi-MCB/RCBO kunye noHlobo lwe-B oluchaza iimpawu zemagnethi kwi-RCCB/RCD.Oku kuthetha ukuba ngoko uya kufumana iimveliso ezifana RCBOs kunye neempawu ezimbini, ezizezi element magnetic ye RCBO kunye element thermal (oku kunokuba Uhlobo AC okanye A magnetic kunye noHlobo B okanye C thermal RCBO).

Zisebenza njani ii-RCD zodidi lwe-B?

Ii-RCD zodidi lwe-B zidla ngokuyilwa zineenkqubo ezimbini zokubona okushiyekileyo.Eyokuqala isebenzisa itekhnoloji ye-'fluxgate' ukwenza ukuba i-RCD ibone i-DC egudileyo yangoku.Okwesibini kusebenzisa iteknoloji efana noHlobo lwe-AC kunye noHlobo lwe-RCDs, oluzimeleyo lombane.
