Isixa sokumelana nomgangatho womzimba womhlaba okanye umzimba wendalo wendalo kunye nokuxhatshazwa kwecingo lokumisa kubizwa ngokuba yi-grounding resistance yesixhobo sokumisa.Ixabiso lokuxhathisa lokumisa lilingana nomlinganiselo we-voltage yesixhobo sokumisa phantsi ukuya kumhlaba okhoyo ogeleza emhlabeni ngomzimba wokumisa.Ukuchasana kokumisa okufunyenwe ngokungena ngokungena emhlabeni ngokujikeleza umzimba kubizwa ngokuba yi-impulse grounding resistance;Uxhathiso olufunyanwa ngamaza ombane aqukuqelayo emhlabeni ngomzimba wokumisa kubizwa ngokuba luxhathiso lwamandla omoya.
I-HV HIPOT GDCR3200C I-Clamp ephindwe kabini yoMvavanyi wokuNchasana noMhlaba
Xa kusenzeka impazamo emhlabeni kwisixhobo sombane, umahluko onokubakho phakathi kwenxalenye esekelwe phantsi kunye nendawo enokubakho enguziro yomhlaba ibizwa ngokuba yivoltheji yokumisa isixhobo sokumisa ukuya emhlabeni okanye isixhobo esinokubakho sokumisa.
Iziphumo ezinokwenzeka zokungasekelwanga kakuhle
1. Iintambo eziphukileyo kunye nokudibanisa okubonakalayo kocingo olusezantsi lunokubangela lula ukuba ucingo lokumisa lutshiswe ngumbane omkhulu okanye ukuchasana okuprintiweyo kukhulu, okubangelwa ukungahambi kakuhle kwamandla.Ukuhlolwa kwekhwalithi yezi zimbini akwenzi i-loop, ukwenzela ukuba amandla aphezulu ecala eliphezulu le-voltage ye-transformer ayikwazi ukusekwa ngokuthe ngqo.Ukongeza, abasebenzi bolondolozo babila kakhulu emva kokuba bephumile emsebenzini, ukuxhathisa komphezulu womzimba womntu kuyancipha, kwaye amandla kwi-transformer akhokelela ngokukhawuleza emhlabeni ngomzimba womntu.Ukuba ingumsinga obulalayo, iya kubangela ukwenzakala okanye ukufa kwabasebenzi bolondolozo.
2. Xa ulungisa i-transformers okanye imigca ye-high-voltage, akukho cingo lokumisa olufakwe kwicala lesibini.Ukuba umatshini we-welding okanye ezinye izixhobo zokuvelisa umbane ohambahambayo zisetyenziselwa kwicala lesibini, kulula ukubangela ukuba icala lesibini libuyisele umbane kunye nokwandisa umbane owenziweyo kwicala eliphambili le-transformer.Ukunyuka kwangoku;ukuba umntu usebenza kwi-transformer, i-voltage yokubuya iphezulu, ikhoyo ngoku inkulu, kwaye kulula ukubangela ukulimala kwabasebenzi.
