Izisetshenziswa Zokugawula Zokuphepha Zomuntu Siqu Esiphezulu Komugqa Wokuphepha Kocingo Lomhlaba
Isingeniso somkhiqizo
I-Earth wire yokuvikela ilungele izintambo zokudlulisa, izitshalo zikagesi kanye nemishini yesiteshi esincane, isisekelo sesekethe esifushane sokulungiswa kokunqamuka kukagesi.
Isethi ephelele yocingo oluvikelekile olusemhlabeni luqukethe induku yokusebenza evalekile enekliphu yokuqhuba, intambo yethusi ethambile ephansi eneshethi ebonisa ngale, iphinikhodi yaphansi noma isiqeshana esiphansi.
I-conductive clamp ihlukaniswe yaba: i-double spring conductive clamp kanye ne-circular spiral conductive clamp esetshenziselwa ukubopha i-conductor, kanye ne-flat spiral conductive clamp esetshenziselwa ukubopha ibha yebhasi.
1.I-Wire clamper ene-aluminium alloy casting, amandla aphezulu, ukuqhuba kahle.
2.Izintambo eziphathwayo ze-short-circuit grounding wire zipakishwe esikhwameni sikaseyili esinamabhokisi okhuni athunyelwa kwamanye amazwe, okulula ukuwuphatha nokuyihambisa.
izindaba ezidinga ukunakwa:
1. Okokuqala hlola ukuthi ulayini ubukhoma futhi uqinisekise ukuthi awekho amandla.
2. Xhuma itheminali ephansi kuqala bese emva kwalokho xhuma ikhondakta.Ukulandelana kokukhipha ucingo oluphansi kufanele kuhlanekezelwe;
3. Amagilavu avikelayo azosetshenziselwa ukuhlanganisa nokuqaqa izintambo eziphansi.Umzimba womuntu akufanele uthinte izintambo eziphansi noma izintambo ezinqanyuliwe ukuze uvimbele ukuqhutshwa kwe-inductive.
