UkuqondaI-RCCB: Ingxenye Ebalulekile Yokuphepha Kukagesi
Ezweni lokuphepha kukagesi, ama-residual current circuit breakers (ama-RCCB) ayizinto ezibalulekile ezivikela abantu nempahla ezingozini zamaphutha kagesi. Uma uhlola ubunzima bama-RCCB, kubalulekile ukuqonda umsebenzi wawo, ukubaluleka kwawo, kanye nenjongo yawo ezinhlelweni zikagesi zanamuhla.
Kuyini i-RCCB?
I-residual current current breaker (RCCB), eyaziwa nangokuthi idivayisi yamanje ehlala njalo (RCD), iyidivayisi kagesi enqamula isekethe kagesi uma ibona ukungalingani kwamandla kagesi phakathi kwezintambo ezibukhoma nezingathathi hlangothi. Lokhu kungalingani kungabangelwa yizizathu eziningana, njengokuxhumanisa okungenaphutha, ukwehluleka kokufakwa kokushisa, noma ukuxhumana komuntu ngengozi nentambo ebukhoma. I-RCCB iqapha njalo amandla kagesi ageleza ngesekethe futhi ingathola ngisho nomehluko omncane, ngokuvamile ophansi njenge-milliamps ezingama-30 (mA). Uma kutholwa ukungalingani, inqamula ngokushesha ukunikezwa kwamandla kagesi, ngaleyo ndlela ivimbele ukushaqeka kukagesi futhi inciphise ingozi yemililo kagesi.
Ukubaluleka kwe-RCCB
Ukubaluleka kwama-RCCB ekuphepheni kukagesi akunakuphikiswa. Izakhiwo eziningi zokuhlala nezebhizinisi ziyadingeka ukufaka ama-RCCB ngokuhambisana nezindinganiso nemithethonqubo ehlukahlukene yokuphepha. Idivayisi iyindlela yokuqala yokuzivikela ezingozini zikagesi futhi inganciphisa kakhulu ingozi yokushaqeka kukagesi nomlilo okubangelwa amaphutha kagesi.
Ngaphezu kokuvikela abasebenzi, ama-RCCB avikela nezinto zikagesi kanye nezinhlelo. Ama-RCCB avikela ekugcwaleni ngokweqile kanye nama-short circuits, esiza ekugcineni ubuqotho bemishini kagesi, ngaleyo ndlela andise isikhathi sokuphila kwemishini futhi anciphise izindleko zokulungisa.
Isimiso sokusebenza se-RCCB
I-RCCB isebenza ngokuthola umehluko kumandla kagesi phakathi kwezintambo ezishisayo nezingathathi hlangothi. Ngokuvamile, amandla kagesi ageleza esiketheni ngentambo eshisayo kufanele alingane namandla kagesi abuya ngentambo engathathi hlangothi. Uma kwenzeka iphutha, njengokuvuza kwamandla kagesi ageleza emhlabathini, i-RCCB ithola lokhu kungalingani.
Uma i-RCCB ithola into engavamile, ibangela indlela enqamula isekethe ngaphakathi kwama-millisecond. Le mpendulo esheshayo ibalulekile ekuvimbeleni ukulimala okukhulu noma ngisho nokufa ngenxa yokushaqeka kukagesi.
Izinhlobo ze-RCCB
Kunezinhlobo eziningana zama-RCCB, ngayinye inenhloso ethile. Izinhlobo ezivame kakhulu zifaka:
1. I-Bipolar RCCB: Isetshenziselwa izifunda zesigaba esisodwa futhi ivame ukusetshenziswa ezindaweni zokuhlala.
2. I-RCCB enama-pole amane: Yakhelwe amasekethe anezigaba ezintathu, avame ukusetshenziswa ezinhlotsheni zezimboni nezentengiselwano.
3. I-RCCB ehlanganisiwe kanye ne-MCB**: Amanye amadivayisi ahlanganisa imisebenzi ye-RCCB kanye ne-Miniature Circuit Breaker (MCB) ukuze ahlinzeke ngokuvikelwa kwamanje okusele kanye nokuvikelwa kokulayisha ngokweqile kuyunithi eyodwa.
Ukufakwa Nokunakekelwa
Ukufakwa okufanele kanye nokugcinwa njalo kwama-residual current circuit breaker (ama-RCCB) kubalulekile ukuqinisekisa ukusebenza kwawo kahle. Kunconywa ukuthi afakwe uchwepheshe kagesi ofanelekayo ukuze ahambisane nemithetho nezindinganiso zikagesi zendawo. Ngaphezu kwalokho, ama-residual current circuit breaker kufanele ahlolwe njalo kusetshenziswa inkinobho yokuhlola enikezwe kudivayisi ukuqinisekisa ukuthi asebenza kahle.
Kafushane
Ngamafuphi, ama-residual current circuit breakers (ama-RCCB) ayingxenye ebalulekile yezinhlelo zikagesi zesimanje, ahlinzeka ngokuvikelwa kukagesi okubalulekile. Angamadivayisi abalulekile avikela impilo nempahla ngokuthola ukungalingani kwamanje nokuxhumanisa amasekethe ngokushesha. Njengoba izindinganiso zokuphepha kukagesi ziqhubeka nokuguquka, ama-RCCB azoqhubeka nokudlala indima ebalulekile ekuqinisekiseni ukuthi imishini kagesi iphephile futhi inokwethenjelwa. Kungakhathaliseki ukuthi kusemakhaya, ehhovisi, noma endaweni yezimboni, ukuqonda nokusebenzisa ama-RCCB kuyisinyathelo esibalulekile esiya endaweni kagesi ephephile.
