Ukuvikelwa kwe-Flashover kuyindlela yokuvikela i-voltage ephezulu, engasetshenziselwa ukuvikelwa kwe-voltage flashover, ukuvikelwa kwe-circuit breaker flashover, ukuvikela ukuvikela i-flashover kawoyela, njll. ohlelweni lwamandla.Ngamafuphi, ukuvikelwa kwe-flashover kuwukubonakaliswa kokuwohloka kwamandla kagesi.
Kuyini ukuvikelwa kwe-flashover I-Flashover ibhekisela esimweni sokuphuma kwamanzi endaweni evikelayo eqinile lapho igesi noma i-dielectric ewuketshezi ezungeze isivikeli esiqinile iphuka.Isimanga.Ukusetshenziswa kokuvikelwa kwe-flashover Ukuvikelwa kwe-flashover kungalungisa i-flashover voltage ezimeni ezahlukene.Isibonelo, uma usebenzisa i-resonance yochungechunge ukuze uqhube i-AC ukumelana ne-voltage kumishini kagesi ene-voltage ephezulu njengezintambo nama-transformer, i-flashover voltage ingalungiswa ngokukhululeka.
Uma i-voltage ye-AC ukumelana isethiwe, kufanelekile ukusetha i-flashover voltage ibe ngu-6~8kv.Kuyafaneleka ukusetha ukuvikelwa kwe-flashover yempahla kagesi engu-35kv ibe ngu-10.5kv.Uma i-voltage yokuvikela i-flashover isethwe inkulu kakhulu noma incane kakhulu, izonikeza impendulo esimweni sangempela sento ehloliwe.nethonya.Ngaphezu kwalokho, ukuvikelwa kwe-flashover nakho kuthinteka ibanga kanye nomswakama.Isibonelo, i-voltage ephezulu endaweni enomswakama kulula ukukhipha umswakama emoyeni.Uma i-voltage yokuvikela i-flashover iphansi kakhulu ngalesi sikhathi, ukuvikelwa kwe-flashover kujwayele ukwenzeka futhi akukwazi ukuhlolwa.Uma iphezulu kakhulu, lapho ukuvikelwa kwe-flashover kwenzeka, iwukuvikela ngokuqondile kwe-flashover yento ehloliwe.
Indlela yokuchaza i-voltage ye-flashover iyahlukahluka kumkhiqizi kuya kumkhiqizi, ezinye zisethwa ngokuzenzakalelayo ngokuya ngobudlelwano be-coefficient ne-voltage yokuhlola, kanti ezinye zichazwa umsebenzisi ngesandla.Kusazoba nezihibe, futhi mina ngokwami ngicabanga ukuthi izilungiselelo ezenziwa ngesandla zingcono.Yini okufanele ngiyenze ngemva kokuvikelwa kwe-flashover?Ungaqhubeki ukulinganisa ngemuva kokuvikela i-flashover, nqamula amandla ensimbi yokuhlola, hlola ibanga lokuphepha lengxenye ngayinye ne-node, lungisa ibanga uma ibanga liseduze kakhulu, bese usebenzisa ukumelana nokufakwa kwe-5000V ukukala ukufakwa kweGround. ukumelana, uma ukumelana nokufakwa kwe-insulation kungaphansi kuka-0.5MΩ, khona-ke ikhebula lingase libe nephutha lokuphuka.Ngalesi sikhathi, ukuhlolwa kwe-high-voltage akukwazi ukuphinda kwenziwe, ngaphandle kwalokho ukulinganisa kungaqhutshekwa.
