Iprofayile yoVavanyo:
Ubushushu / ukufuma / uvavanyo olubanzi loxinzelelo oluphantsi lusetyenziswa ikakhulu ukufumanisa ukuba imveliso inokumelana nokukwazi ukugcina okanye ukusebenza kwindawo yobushushu / ukufuma / uxinzelelo oluphantsi.Njengokugcinwa okanye ukusebenza kwiindawo eziphakamileyo, ukuthuthwa okanye ukusebenza kwiikhabhinethi ezixinzelelekileyo okanye ezinganyangekiyo zeenqwelo-moya, ukuthutha ngaphandle kwenqwelomoya, ukuvezwa kweendawo zokudakumba ngokukhawuleza okanye eziqhumayo, njl.
Iingozi eziphambili zoxinzelelo lomoya ophantsi kwiimveliso zezi:
▪ Iziphumo zomzimba okanye iikhemikhali, ezifana nokuguqulwa kwemveliso, umonakalo okanye ukuphuka, utshintsho kwizinto eziphathekayo kunye neekhemikhali zezinto ezinoxinano oluphantsi, ukuhanjiswa kobushushu obuncitshisiweyo kubangela ukuba izixhobo zigqithise ukushisa, ukungaphumeleli kokutywinwa, njl.
▪ Iziphumo zombane ezifana ne-arcing ebangela ukusilela kwemveliso okanye ukusebenza okungazinzanga.
▪ Iziphumo zokusingqongileyo ezifana notshintsho kwiipropati ze-dielectric zegesi ephantsi yoxinzelelo kunye nomoya zikhokelela ekutshintsheni umsebenzi kunye nokusebenza kokhuseleko lweesampuli zovavanyo.Uxinzelelo lwe-atmospheric ephantsi, ngakumbi xa idibaniswe namaqondo okushisa aphezulu, amandla e-dielectric yomoya ayancipha kakhulu, okubangelwa umngcipheko wokwanda kwe-arcing, i-surface okanye i-corona yokukhutshwa.Utshintsho kwizinto eziphathekayo ngenxa yokushisa okuphantsi okanye okuphezulu kwandisa umngcipheko wokuguqulwa okanye ukuphuka kwezixhobo ezitywiniweyo okanye amacandelo phantsi koxinzelelo lomoya ophantsi.
