I-CJB1 18mm Ububanzi 1p+N Ipulaki ku-Circuit Breaker 6ka Isithombe Esifakiwe Sesigaba Esisodwa

I-CJB1 18mm Ububanzi 1p+N Ipulaki ku-Circuit Breaker 6ka Isigaba Esisodwa

Incazelo emfushane:

1. Isicelo:Ngokuvikela izintambo nezinto zokusebenza ekulayisheni ngokweqile naseseketheni elifushane.

2. Imithetho ejwayelekile yokukhetha i-MCB.

2.1 Idatha yezobuchwepheshe yenethiwekhi endaweni ecatshangelwe:

Amasistimu we- earthing, i-short-circuit yamanje endaweni yokufaka i-breaker circuit, okufanele ngaso sonke isikhathi ibe ngaphansi komthamo wokuphuka walolu cingo, ugesi ojwayelekile wenethiwekhi.

2.2 Kunezici ezi-3 zejika zokusebenza kazibuthe:

Ijika elingu-B (3-5 In) ukuvikela nokulawula amasekhethi kumakhebuli obude kumasistimu e-TN ne-IT.

I-C curve (5-10 In) ukuvikela nokulawula amasekhethi ngokumelene nokulayishwa ngokweqile kanye nama-short-circuits;isivikelo semithwalo ephikisanayo ne-inductive ene-inrush current ephansi.

Ijika lika-D(10-20 In) ukuvikela nokulawula amasekhethi ngokumelene nokulayishwa ngokweqile kanye nama-short-circuits;isivikelo samasekhethi ahlinzeka ngemithwalo enamandla aphezulu okungena ngaphakathi ekuvaleni kwesekethe (ama-LV/LV transformer, amalambu okuwahlukanisa).

3. I-CJB1 inomkhawulo ophezulu wokusebenza kwamanje ukuze kukhawulwe amandla okususwa ngenxa yokujikeleza okufushane ngezinga elikhulu kakhulu.
