Ukuqonda i-RCCB: I-Residual Current Breaker
Ezweni lokuphepha kukagesi,ama-residual current breakers (ama-RCCB)zidlala indima ebalulekile ekuvikeleni abantu nempahla ezingozini zikagesi. Lawa madivayisi aklanyelwe ukuvimbela ukushaqeka kukagesi nokunciphisa ingozi yemililo kagesi ebangelwa amaphutha omhlaba. Lesi sihloko sizogxila emsebenzini, ukubaluleka, kanye nokusetshenziswa kwama-RCCB.
Kuyini i-RCCB?
An I-RCCB (Isiphuli Sesekethe Samanje Esisele)iyithuluzi likagesi eliphazamisa isekethe kagesi uma libona ukungalingani phakathi kwezintambo ezibukhoma (isigaba) nezingathathi hlangothi. Lokhu kungalingani kubonisa ukuvuza kwamanje emhlabathini, okungabangelwa amaphutha ezintambo, umonakalo wokushisa, noma ukuxhumana ngengozi nezingxenye ezibukhoma. I-RCCB iqapha njalo ugesi ogeleza ngesekethe. Uma umehluko wamanje otholiwe udlula ukuzwela kwawo okulinganiselwe (ngokuvamile okungu-30mA ukuze kuvikelwe umuntu), uyakhubeka ngaphakathi kwama-millisecond bese unqamula ukunikezwa kwamandla.
Isebenza kanjani i-RCCB?
I-RCCB isebenza ngesimiso sokushintshashintsha kwamandla kagesi. Yakhiwe yi-iron core kanye nama-coil amabili: elilodwa le-live wire kanye nelinye le-neutral wire. Ngaphansi kwezimo ezivamile, ama-current alinganayo ageleza ezintanjeni ezimbili, futhi amasimu kazibuthe akhiqizwa ama-coil ayahlukana. Kodwa-ke, uma kwenzeka iphutha, njengokuthinta intambo ephilayo, ama-current avuza phansi, okudala ukungalingani. Lokhu kungalingani kudala insimu kazibuthe ebangela indlela yokukhubeka, ivule isekethe futhi ivimbele umonakalo ongaba khona.
Ukubaluleka kwe-RCCB
Ukubaluleka kwama-RCCB akunakuphikiswa. Ayindlela ebalulekile yokuzivikela ekushayweni ugesi, okungabangela ukulimala okukhulu noma ngisho nokufa. Izibalo zokuphepha zibonisa ukuthi ingxenye enkulu yezehlakalo zikagesi ibangelwa amaphutha omhlaba, okwenza ama-RCCB abaluleke kakhulu ezindaweni zokuhlala, zezentengiselwano kanye nezezimboni.
Ama-RCCB nawo adlala indima ebalulekile ekuvimbeleni imililo kagesi. Izintambo noma izinto zikagesi ezingasebenzi kahle zingabangela ukuvuza kukagesi, okungathi uma kungatholakali, kuholele ekushiseni ngokweqile nasemoyeni. Ama-RCCB ayakhubeka lapho ethola iphutha, okusiza ekunciphiseni lezi zingozi nokuvikela impilo nempahla.
Ukusetshenziswa kwe-RCCB
- Izakhiwo Zokuhlala:Ezakhiweni zokuhlala, kufakwa i-RCCB ebhodini lokusabalalisa eliyinhloko ukuze kuvikelwe zonke izifunda. Ama-RCCB abaluleke kakhulu ezindaweni ezinomswakama ophezulu, njengezindlu zangasese namakhishi, lapho ingozi yokushayiswa ugesi iphezulu khona.
- Izindawo zezentengiselwano:Amabhizinisi avame ukusebenzisa ama-residual current circuit breaker ukuvikela abasebenzi namakhasimende. Abalulekile ezindaweni lapho izinto zikagesi zisetshenziswa khona njalo, njengezindawo zokudlela, ama-workshop, kanye nezitolo zokudayisa.
- Izindawo zezimboni:Emafektri nasezitshalweni zezimboni, ama-RCCB avikela imishini nabasebenzi emaphutheni kagesi. Abalulekile ezindaweni lapho kusebenza khona imishini esindayo, njengoba ingozi yezingozi zikagesi iphakeme kakhulu.
- Ukufakwa Kwangaphandle:Ama-RCCB asetshenziswa nasezindaweni zikagesi zangaphandle ezifana nokukhanyisa engadini kanye namachibi okubhukuda lapho ingozi yokushaqeka kukagesi ikhuphuka khona ngenxa yokuba khona kwamanzi.
Ngokufigqiwe
Kalula nje, ama-residual current circuit breakers (ama-RCCB) ayisici esibalulekile sezinhlelo zikagesi zanamuhla. Athola futhi anqamule ama-circuit anephutha, avikele abantu ekushaqekeni kukagesi futhi avimbele imililo kagesi engaba khona. Njengoba ukuthembela kwethu kugesi ekuphileni kwethu kwansuku zonke kukhula, ukuqonda nokusebenzisa ama-RCCB kuzohlala kuyisici esiyisisekelo sokuphepha kukagesi. Kungakhathaliseki ukuthi kusezindaweni zasekhaya, kwezentengiselwano, noma kwezimboni, ama-RCCB ahlinzeka ngokuvikelwa okusebenzayo ezingozini zikagesi, okuqinisekisa ikusasa eliphephile kubo bonke.
