Ukuqonda Ukubaluleka Kwama-RCBO Ekuvikeleni Kwesekethe

Emhlabeni wokuvikelwa kwesekethe, igama elithi MCB limele i-miniature circuit breaker. Le divayisi ye-electromechanical idlala indima ebalulekile ekuvaleni ngokuzenzekelayo isekethe lapho kutholwa izimo ezingavamile. I-Overcurrent ebangelwa ukujikeleza okufushane itholwa kalula yi-MCB. Umgomo wokusebenza wama-breaker circuit amancane ulula futhi uyasebenza. Iqukethe oxhumana nabo ababili; eyodwa ilungisiwe futhi enye iyasuswa. Uma ukwanda kwamanje, abathintwayo abasusekayo bayanqamuka koxhumana nabo abalungisiwe, bavule isekethe futhi bayinqamule kumthombo wamandla omkhulu. Nokho, ezinhlelweni zikagesi eziphambili zanamuhla, indima yeI-RCBO(i-residual current circuit breaker enokuvikelwa kwe-overcurrent) ekuhlinzekeni ukuvikeleka okuphelele kwamasekhethi kuya ngokuya kubaluleke kakhulu.

Ama-RCBOsziyizingxenye ezibalulekile ezinhlelweni zikagesi zesimanje, ezihlinzeka ngenhlanganisela yokuvikelwa kwamanje okusele kanye nokuvikela okudlulele kudivayisi eyodwa. Zenzelwe ukuvikela ama-circuits kusuka ku-overcurrent, okuyiphutha likagesi elibangelwa ukulayisha ngokweqile noma isifunda esifushane. Ukuvikelwa kwamanje okuyinsalela okuhlanganiswe ku-RCBO kwengeza isendlalelo esengeziwe sokuphepha ngokuthola nokuphula isekethe lapho kuvuza kwamanje, okungase kubangele ukushaqeka noma ingozi yomlilo. Lokhu kusebenza okuthuthukisiwe kwenza i-RCBO ibe yingxenye ebalulekile ekuqinisekiseni ukuphepha nokuthembeka kokufakwa kukagesi.

Enye yezinzuzo eziyinhloko zeAma-RCBOs yikhono lokuhlinzeka ngokuvikeleka komuntu ngamunye kusekethe ngayinye. Ngokungafani nama-MCB endabuko ahlinzeka ngokuvikela okudlulele kwesekethe yonke, ama-RCBO ahlukanisa futhi avikele amasekhethi angawodwana ngaphakathi kwebhodi lokusabalalisa. Leli zinga lobumbudumbudu bokuvikela linenzuzo ikakhulukazi ezindaweni zokuhlala, ezentengiselwano, nezimboni lapho amasekethe ahlukene angase abe namazinga ahlukene okuzwela kanye nezidingo zomthwalo. Ngokuhlanganisa ama-RCBO kwingqalasizinda yamandla, ubungozi bokucisha ugesi okusabalele ngenxa yokwehluleka okwenziwe endaweni yehliswa kakhulu, ngaleyo ndlela kuthuthukiswe ukuqina kukonke kwesistimu yamandla.

Idizayini ehlangene yama-RCBO iwenza alungele ukufakwa kukagesi kwesimanje lapho ukulungiselelwa kwendawo kubaluleke kakhulu. Zihlanganisa ukuvikelwa kwamanje okuyinsalela nokuvikela okudlulele kudivayisi eyodwa, ukwenza kube lula isu lonke lokuvikela isekethe, ukunciphisa isidingo sezingxenye eziningi nokwenza lula inqubo yokufaka. Lokhu akusizi nje kuphela ukulondoloza izindleko, futhi kuqinisekisa ukuhlelwa kwephaneli kagesi esebenza kahle futhi ehlelekile.

Ukuhlanganiswa kwama-RCBOs ekuvikelweni kwesekethe kumele intuthuko enkulu ekuqinisekiseni ukuphepha nokuthembeka kokufakwa kukagesi. Ngokuhlanganisa ukuvikelwa kwamanje okuyinsalela nokuvikela okudlulele kudivayisi eyodwa, ama-RCBO ahlinzeka ngokuvikeleka okuphelele kwamasekhethi angawodwana, ngaleyo ndlela athuthukise ukuqina kukonke kwesistimu kagesi. Idizayini yayo ehlangene kanye nokusebenza okulula kuyenza ilungele ukufakwa kukagesi kwesimanje, okuhlinzeka ngesixazululo esisebenzayo sokuvikela isekethe ngokufanele. Njengoba isidingo sokuphepha kukagesi okuthuthukisiwe siqhubeka sikhula, indima yama-RCBO ekuvikeleni amasekhethi izoba yinto ebalulekile embonini.
