RCCB Residual Current Device Circuit Breaker RCD
Khoom Taw Qhia
Hom B RCCBs, ntxiv rau AC ib txwm muaj, tuaj yeem kuaj xyuas cov zaus AC thiab cov dej ntshiab DC lub ntiaj teb.Txo qhov kev pheej hmoo ntawm hluav taws kub thiab / los yog hluav taws xob los ntawm kev txiav tsis siv neeg ntawm cov khoom siv hluav taws xob tso siab rau kev xaiv ntawm hom RCCB raug.
Muaj nuj nqi
● Tswj cov kab hluav taws xob.
● Tiv thaiv tib neeg tiv thaiv kev tiv tauj tsis ncaj thiab tiv thaiv ntxiv tiv thaiv kev tiv tauj ncaj qha.
● Tiv thaiv kev teeb tsa tiv thaiv hluav taws kub vim muaj kev cuam tshuam ntawm rwb thaiv tsev.
1. Muab kev tiv thaiv lub ntiaj teb txhaum/kawg tam sim no thiab kev ua haujlwm ntawm kev sib cais.
2. High short-circuit tam sim no muaj peev xwm.
3. Muaj feem xyuam rau lub davhlau ya nyob twg thiab tus pin / diav rawg hom busbar kev sib txuas.
4. Nruab nrog ntiv tes tiv thaiv kev sib txuas terminals.
5. Tsis siv neeg txiav lub voj voog thaum lub ntiaj teb ua txhaum / qhov hluav taws xob tam sim no tshwm sim thiab tshaj qhov ntsuas rhiab heev.
6. Kev ywj pheej ntawm cov khoom siv hluav taws xob thiab kab hluav taws xob, thiab tsis muaj kev cuam tshuam sab nraud, kev hloov pauv voltage.
Residual Current Circuit Breaker muaj feem xyuam rau cov hluav taws xob hluav taws xob nrog cov ntsuas hluav taws xob 230/400V AC, zaus 50/60Hz thiab ntsuas tam sim no mus txog 80Amp.
1. RCCB nrog ntsuas rhiab heev txog 30mA tuaj yeem siv los ua cov cuab yeej tiv thaiv ntxiv nyob rau hauv rooj plaub uas lwm yam khoom siv tiv thaiv tsis ua haujlwm tiv thaiv hluav taws xob.
2. RCCB tsim rau kev teeb tsa hauv tsev thiab lwm daim ntawv thov zoo sib xws, yog rau kev ua haujlwm tsis yog kev tshaj lij, thiab tsis tas yuav tsum muaj kev saib xyuas.
3. RCCB tsis muaj kev tiv thaiv hluav taws xob uas tshwm sim los ntawm kev sib cuag ncaj qha ntawm ob txoj kab tiv thaiv, lossis cov xau tam sim no ntawm ob kab no.
4. Cov khoom siv tshwj xeeb xws li cov khoom tiv thaiv surge, surge arrester thiab lwm yam raug pom zoo rau nruab rau ntawm cov kab ntws mus rau RCCB raws li kev ceev faj tiv thaiv qhov muaj peev xwm surge voltage thiab tam sim no tshwm sim ntawm nws lub hwj chim input sab.
5. Txaus siab rau tej yam kev mob thiab kev siv raws li tau hais los saum toj no, RCCB nrog °∞ON-OFF° ± qhov taw qhia ntaus ntawv yog suav tias tsim nyog rau kev cais tawm.
