Luyini Uhlobo B RCD?

Uma ucwaninga ngokuphepha kukagesi, kungenzeka ukuthi uhlangabezane negama elithi “Type B RCD”. Kodwa yini ngempela i-Type B RCD? Ihluke kanjani kwezinye izingxenye zikagesi ezinemisindo efanayo? Kulokhu okuthunyelwe kwebhulogi, sizongena emhlabeni wama-RCD ohlobo lwe-B futhi sinikeze imininingwane okudingeka ukwazi ngawo.

Ama-RCD oHlobo lwe-B ayizingxenye ezibalulekile ezinhlelweni zikagesi futhi aklanyelwe ukuhlinzeka ngokuvikelwa ekushayweni kukagesi kanye nomlilo obangelwa amaphutha omhlaba. Kodwa-ke, kufanelekile ukuqaphela ukuthi naphezu kwamagama afanayo, akufanele adidaniswe nohlobo lwe-B MCB noma ama-RCBO. Ama-RCD oHlobo lwe-B aklanyelwe ngokukhethekile ukubona nokuhamba ngokuphendula amaphutha aphansi e-AC ne-DC, awenze afanelekele uhla olubanzi lwezinhlelo zikagesi.

Ngakho-ke, yini eyenza uhlobo B RCD luhluke kwezinye izingxenye ezifanayo? Umehluko oyinhloko ulele emandleni abo kanye nezinhlobo zamaphutha abakwazi ukuwabona. Ama-MCBs ohlobo B kanye nama-RCBO avikela ngokuyinhloko ekulayisheni ngokweqile namasekhethi amafushane, kuyilapho ama-RCD oHlobo lwe-B egxila ekutholeni amaphutha aphansi, awenze isici sokuphepha esibalulekile ekufakweni kukagesi.

Kubalulekile ukuqonda ukuthi uhlamvu “B” ohlotsheni lwe-RCD B lusho izici ezihlukile ku-Type B MCB noma i-RCBO. Ukudideka kuvela ekusetshenzisweni kwezinhlamvu ezifanayo ukuze kuqondwe izici ezihlukene ngaphakathi kwensimu yezinto zokuvikela zikagesi. Kuma-RCD oHlobo lwe-B, uhlamvu “B” lubhekisela ngokukhethekile ezintweni kazibuthe ukuze zihlukanise kwezinye izinhlobo zama-RCD angase abe nezici ezihlukene zokukhubeka.

Uma useshela Uhlobo B RCDs, ungase uhlangabezane nemikhiqizo enezinto zombili ezishisayo nezikazibuthe, njengama-RCBO anezici kazibuthe zohlobo B. Lokhu kugcizelela ukubaluleka kokuqonda izici ezithile nemisebenzi yamadivayisi ahlukene okuvikela ugesi kanye namandla okudideka ngenxa yezimiso ezifanayo zokweqa amagama.

Eqinisweni, ama-RCD oHlobo lwe-B abalulekile ukuze kuqinisekiswe ukuvikeleka okuphelele kwamaphutha omhlaba ezinhlelweni ezihlukene zikagesi, okuhlanganisa nalawo ahlanganisa amasekhethi wamanje (DC). Lokhu kubenza babe ingxenye ebalulekile ezindaweni lapho kunengozi yamaphutha aphansi e-DC, njengeziteshi zokushaja izimoto zikagesi, ukufakwa kwamandla avuselelekayo nezimo zezimboni.

Kafushane, ama-RCD oHlobo lwe-B adlala indima ebalulekile ekuphepheni kukagesi ngokunikeza ukuvikeleka kumaphutha aphansi, okuhlanganisa amaphutha e-AC ne-DC. Nakuba umgomo wokuqamba amagama ufana, kubalulekile ukuhlukanisa ama-RCD oHlobo lwe-B kwezinye izinhlobo zemishini yokuvikela kagesi, njenge-Type B MCBs kanye nama-RCBO. Ngokuqonda imisebenzi ethile kanye nezici ze-RCD yohlobo lwe-B, ungaqinisekisa ukuthi izinyathelo zokuphepha zikagesi zisetshenziswa ngendlela efanele ezinhlelweni ezihlukene.

Lapho ukhetha izisetshenziswa zikagesi zokuvikela iphrojekthi yakho, qiniseka ukuthi ucabangela izidingo ezithile zokuvikela iphutha eliphansi bese ukhetha I-RCD Yohlobo B lapho kufanele khona. Ngokubeka phambili ukuphepha kukagesi nokuhlala unolwazi lwakamuva ngentuthuko yakamuva yobuchwepheshe bokuvikela, ungakha ingqalasizinda kagesi ephephile, ethembeke kakhulu.
