I-Residual Circuit Breaker: Isiqinisekiso Sikagesi Esiphephile

UkuqondaAma-Residual Circuit Breakers: Umhlahlandlela Ophelele

Emkhakheni wokuphepha kukagesi, ama-residual current circuit breakers (ama-RCB) adlala indima ebalulekile ekuvikeleni abantu nempahla emaphutheni kagesi. Le divayisi yenzelwe ukubona ukungalingani kwamanje nokuvula isekethe lapho kutholakala iphutha, ngaleyo ndlela kuvinjelwe izingozi ezingaba khona njengokushaqeka kukagesi nomlilo. Kulesi sihloko, sizobheka kabanzi ukuthi ama-earth leakage circuit breakers asebenza kanjani, izinzuzo zawo, kanye nezinhlelo zokusebenza kwawo.

Iyini i-leaking circuit breaker?

I-residual current current breaker, evame ukubizwa ngokuthi i-residual current device (RCD) noma i-residual current current circuit breaker (RCCB), iyidivayisi kagesi eqapha ugesi ku-electric circuit. Ihlala iqhathanisa ugesi ogeleza ngezintambo ezibukhoma nezingathathi hlangothi. Ngokuvamile, ugesi kuzo zombili izintambo kufanele ulingane. Kodwa-ke, uma kwenzeka iphutha, njenge-short circuit noma othile othinta intambo ebukhoma, ugesi ungangalingani. I-RCB ithola lokhu kungalingani futhi ivule i-circuit ngokushesha, ngokuvamile ngaphakathi kwama-millisecond ambalwa.

Isebenza kanjani i-leaking circuit breaker?

Ukusebenza kwama-earth leakage circuit breakers kusekelwe esimisweni sokungeniswa kwe-electromagnetic. Idivayisi inomgogodla wensimbi oqukethe ama-coil amabili: elilodwa lentambo ephilayo kanye nelinye lentambo engathathi hlangothi. Uma imisinga ilinganisiwe, amasimu kazibuthe akhiqizwa yila ma-coil ayakhiphana. Kodwa-ke, uma kukhona umusi wokuvuza (okubonisa iphutha), amasimu kazibuthe ngeke aphume, okubangela ukuthi indlela yokuqalisa yamanje ehlukile ikhubeke isekethe.

Ama-RCB amaningi aklanyelwe ukukhubeka kugesi othize ovuzayo, ngokuvamile asukela ku-30 ​​mA ukuze avikeleke kuye ku-100 mA noma ngaphezulu ukuze avikele imishini. Lokhu kuzwela kuqinisekisa ukuthi ngisho nokuvuza okuncane okungaba yingozi yokushaqeka kukagesi kutholakala ngokushesha futhi kuxazululwe.

Izinzuzo zokusebenzisa i-earth leakage circuit breaker

1. Ukuphepha Okuthuthukisiwe: Inzuzo eyinhloko ye-RCB ukuphepha okuthuthukisiwe ekunikezayo. Ngokunqamula isekethe uma kwenzeka iphutha, ingozi yokushaqeka kukagesi kanye nomlilo kagesi ingancishiswa kakhulu.

2. Ukuvikelwa Kwemishini: Ngaphezu kokuqinisekisa ukuphepha kwempilo yabantu, i-RCB ingavikela nezinto zikagesi nemishini emonakalweni obangelwa amaphutha kagesi.

3. UKUHAMBISANA NEKHODI: Amakhodi amaningi okuphepha kagesi kanye namakhodi okwakha adinga ukufakwa kwama-residual circuit breakers ezindaweni zokuhlala nezentengiselwano. Ukusetshenziswa kwe-RCB kuqinisekisa ukuhambisana nalezi zindinganiso.

4. Ukuthula Kwengqondo: Ukwazi ukuthi kufakwe i-leaking circuit breaker kunganikeza abanikazi bezindlu nabanikazi bamabhizinisi ukuthula kwengqondo, okubavumele ukuthi basebenzise imishini kagesi ngaphandle kokukhathazeka ngezingozi ezingaba khona.

Ukusetshenziswa kwe-earth leakage circuit breaker

Ama-Earth leakage circuit breakers asetshenziswa kabanzi ezimweni ezahlukene, okuhlanganisa:

- UKWAKHIWA KWENDAWO YOKUHLALA: Ama-RCB avame ukufakwa emakhaya ukuze avikeleke ekushayweni ugesi, ikakhulukazi ezindaweni ezichayeke emanzini njengezindlu zangasese namakhishi.

- Izindlu Nezindawo Zokuhweba: Amabhizinisi asebenzisa i-RCB ukuqinisekisa ukuphepha kwabasebenzi namakhasimende, nokuvikela imishini ebucayi.

- Izindawo Zezimboni: Emafektri nasezindaweni zezimboni, ama-RCB abalulekile ekuvikeleni imishini nokuqinisekisa ukuphepha kwabasebenzi ezindaweni ezinobungozi obukhulu.

Ngokufigqiwe

Ngamafuphi, ama-earth leaking circuit breakers ayingxenye ebalulekile yezinhlelo zikagesi zanamuhla, ahlinzeka ngokuvikelwa okubalulekile emaphutheni kagesi. Ikhono lawo lokubona ukungalingani kwamanje nokunqamula ngokushesha ama-circuit lenza libe yithuluzi elibalulekile lokuphepha emakhaya, emabhizinisini nasezindaweni zezimboni. Ngokuqonda ukubaluleka nemisebenzi yama-earth leaking circuit breakers, abantu ngabanye nezinhlangano bangathatha izinyathelo zokuthuthukisa ukuphepha kukagesi kanye nokuhambisana nemithetho. Ukutshala imali ku-RCB kungaphezu nje kokuthobela imithetho; kungukuzibophezela ekuphepheni nasenhlalakahleni ezweni lethu elikhula ngamandla kagesi.
