I-RCCB Residual Current Device Circuit Breaker RCD

Ama-RCCB ohlobo lwe-B, ngaphezu kwe-AC evamile, angathola imvamisa ephezulu ye-AC nama-DC ahlanzekile okuvuza komhlaba.Ukunciphisa ubungozi bomlilo kanye/noma ugesi ngokunqanyulwa okuzenzakalelayo kokuphakelwa kukagesi kuncike ekukhetheni uhlobo olulungile lwe-RCCB.

Umsebenzi
● Lawula amasekhethi kagesi.
● Vikela abantu koxhumana nabo abangaqondile kanye nokuvikela okwengeziwe koxhumana nabo ngokuqondile.
● Vikela izinto ezifakwayo engozini yomlilo ngenxa yamaphutha okushisa.
 
1. Inikeza isivikelo ngokumelene nephutha lomhlaba/ukuvuza kwamandla kanye nomsebenzi wokuzihlukanisa.
2. Umthamo wokumelana nomthamo wamanje we-short-circuit wamanje.
3. Isebenza kutheminali kanye noxhumano lwebha yebhasi yephini/imfoloko.
4. Ifakwe amatheminali okuxhumana avikelwe ngomunwe.
5. Nqamula ngokuzenzakalelayo isekethe lapho iphutha lomhlaba/ukuvuza kwamandla kwenzeka futhi kudlula ukuzwela okulinganiselwe.
6. Akuzimele ekuhlinzekeni kwamandla kagesi kanye nolayini kagesi, futhi akunakuphazamiseka kwangaphandle, ukushintshashintsha kwamandla kagesi.
 
I-Residual Current Circuit Breaker iyasebenza kumasekhethi kagesi ane-voltage elinganiselwe engu-230/400V AC, imvamisa engu-50/60Hz futhi ikalwe okwamanje kufika ku-80Amp.
1. I-RCCB enokuzwela okulinganiselwe kufika ku-30mA ingasetshenziswa njengesisetshenziswa sokuvikela esingeziwe uma kwenzeka enye idivayisi evikelayo yehluleka ukuvikeleka ekushaqekeni kukagesi.
2. I-RCCB yakhelwe ukufakwa kwasendlini nezinye izinhlelo zokusebenza ezifanayo, ezokusebenza okungezona ezochwepheshe, futhi akukho kulungiswa okudingekayo.
3. I-RCCB ayihlinzeki ngokuvikelwa ekushayweni kukagesi okubangelwa ukuthintwa okuqondile kwazo zombili izintambo ezivikelwe, noma ukuvuza kwamandla phakathi kwalezi zintambo ezimbili.
4. Izinsiza ezikhethekile ezifana nemishini yokuvikela ama-surge, i-surge arrester njll ziyatuswa ukuthi zifakwe kulayini okhuphuka nomfula ku-RCCB njengesexwayiso ngokumelene namandla kagesi akhuphukayo kanye nokwenzeka kwamanje ngasohlangothini lwawo lokufaka amandla.
5. Izimo nezinhlelo zokusebenza ezanelisayo njengoba kushiwo ngenhla, i-RCCB ene-°∞ON-OFF°± idivayisi ekhombisayo ibhekwa njengefanele umsebenzi wokuzihlukanisa.
