UkuqondaAma-Breaker Esifunda Sokuvuza Komhlaba Wohlobo B: Umhlahlandlela Ophelele
Emkhakheni wokuphepha kukagesi, ama-residual current circuit breakers (ama-RCCB) adlala indima ebalulekile ekuvikeleni abasebenzi kanye nemishini emaphutheni kagesi. Phakathi kwezinhlobo ezahlukene zama-RCCB atholakala emakethe, ama-Type B RCCB avelele ngenxa yezici zawo ezihlukile kanye nezinhlelo zokusebenza. Lesi sihloko sizogxila ezicini, izinzuzo, kanye nokusetshenziswa kwama-Type B RCCB, okuhlinzeka ngokuqonda okuphelele kwalesi sici sikagesi esibalulekile.
Iyini i-RCCB yohlobo B?
Ama-RCCB ohlobo lwe-AB, noma ama-residual current current breakers ohlobo lwe-B, asetshenziselwa ukuthola nokuphazamisa ama-residual current kuma-circuits. Ngokungafani nama-RCCB ajwayelekile, afaneleka kakhulu ekusetshenzisweni kwama-current alternating (AC), ama-RCCB ohlobo lwe-B angaphatha ama-AC kanye nama-residual current aqondile (DC). Lokhu kuwenza abe usizo kakhulu ekufakweni kukagesi kwesimanje, ikakhulukazi ngokwamukelwa okukhulayo kwemithombo yamandla avuselelekayo njengamaphaneli elanga kanye neziteshi zokushaja izimoto zikagesi.
Izici eziyinhloko ze-Type B RCCB
1. Ukutholwa Kwamanje Okubili: Esinye sezici eziphawulekayo zama-RCCB ohlobo B yikhono lawo lokubona kokubili amaza asele e-AC kanye ne-DC. Lokhu kusebenza okubili kuwenza akwazi ukuhlinzeka ngokuvikelwa ezinhlobonhlobo zezinhlelo zokusebenza, kufezwe ukuguquguquka nokuthembeka.
2. Ukuzwela Okuphezulu: Ama-RCCB ohlobo B aklanyelwe ukukhubeka kumaza aphansi asele (ngokuvamile angu-30mA noma angu-300mA). Lokhu kuzwela okuphezulu kubalulekile ukuvimbela ukushaqeka kukagesi nokunciphisa ingozi yemililo kagesi.
3. Umklamo Ohlanganisiwe: Ama-RCCB amaningi ohlobo B ayinkimbinkimbi futhi angafakwa kalula kuma-switchboard ahlukahlukene ngaphandle kokuthatha isikhala esiningi kakhulu.
4. Ihambisana nezindinganiso: Ama-RCCB ohlobo B akhiqizwa ngokuhambisana nezindinganiso zokuphepha zomhlaba wonke, okuqinisekisa ukuthi ahlangabezana nezidingo ezidingekayo zokuphepha nokusebenza kukagesi.
Izinzuzo zokusebenzisa i-Type B RCCB
1. Ukuphepha Okuthuthukisiwe: Inzuzo eyinhloko yokusebenzisa i-Type B RCCB ukuphepha okuthuthukisiwe ekunikezayo. Ngokubona nokuphazamisa ugesi osele, la madivayisi anciphisa kakhulu ingozi yokushaqeka kukagesi kanye nemililo kagesi, ngaleyo ndlela avikele abantu kanye nempahla.
2. Ukuguquguquka: Ama-RCCB ohlobo B afanelekela izinhlelo zokusebenza ezahlukahlukene, okuhlanganisa izindawo zokuhlala, zezentengiselwano, kanye nezindawo zezimboni. Amandla awo okusingatha kokubili amaza e-AC kanye ne-DC awenza afanelekele izinhlelo zamandla avuselelekayo kanye nokufakwa kwezimoto zikagesi.
3. Ukuthobela Imithetho: Izifunda eziningi zinemithetho edinga ukusetshenziswa kwama-residual current current breakers ohlobo B ezisetshenziswayo ezithile, ikakhulukazi lezo ezihilela izinhlelo zamandla elanga. Ukusebenzisa la madivayisi kuqinisekisa ukuhambisana namakhodi nezindinganiso zikagesi zendawo.
4. Ukonga Izindleko Zesikhathi Eside: Nakuba izindleko zokuqala ze-RCCB Yohlobo B zingase zibe phezulu kune-RCCB ejwayelekile, ikhono layo lokuvimbela amaphutha kagesi lingabangela ukonga okukhulu kwezindleko zesikhathi eside. Ngokunciphisa ingozi yokulimala kwemishini nokulungiswa okubizayo, i-RCCB Yohlobo B iwutshalomali olufanele kunoma yikuphi ukufakwa kukagesi.
Ukusetshenziswa kwe-Type B RCCB
Ama-RCCB ohlobo B avame ukusetshenziswa ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa:
- Izinhlelo Zokukhiqiza Amandla Elanga: Njengoba ukwanda kwamandla elanga kuthandwa, ama-RCCB ohlobo B abalulekile ukuvikela ama-inverter elanga nokuqinisekisa ukuphepha kokufakwa kwamandla elanga.
- Iziteshi Zokushaja Izimoto Zikagesi: Njengoba izimoto zikagesi zithandwa kakhulu, ama-RCCB ohlobo B abalulekile ukuvikela iziteshi zokushaja emaphutheni kagesi angaba khona.
- Imishini Yezimboni: Imishini eminingi yezimboni kanye nemishini ikhiqiza ugesi oqondile, ngakho-ke ama-RCCB ohlobo B ayizingxenye ezibalulekile zokuqinisekisa ukuphepha ezindaweni zokukhiqiza nezokucubungula.
Kafushane
Ngamafuphi, ama-residual current current breakers ohlobo B (ama-RCCB) ayisici esibalulekile sezinhlelo zokuphepha kagesi zanamuhla. Amandla awo okuthola kokubili ama-residual current AC kanye ne-DC, ukuzwela okuphezulu, kanye nokuhambisana nezindinganiso zokuphepha kuwenza abe ukukhetha okuthembekile kwezinhlelo eziningi ezahlukene. Njengoba kuqhubeka ukukhula kwesidingo sezixazululo zamandla avuselelekayo kanye nezimoto zikagesi, ukubaluleka kwama-residual current current current circuit breakers ohlobo B (ama-RCCB) ekuqinisekiseni ukuphepha kukagesi akunakubukelwa phansi. Ukutshala imali kula madivayisi akugcini nje ngokuthuthukisa ukuphepha kodwa futhi kuthuthukisa ukusebenza kahle kanye nokuthembeka kwemishini kagesi.
