Ukukhuselwa kwe-Flashover yindlela yokukhusela i-high-voltage, engasetyenziselwa ukukhusela i-voltage flashover, ukukhuselwa kwe-circuit breaker flashover, ukukhuselwa kwe-oil flashover, njl njl kwinkqubo yamandla.Ngamafutshane, ukukhuselwa kwe-flashover kukubonakalisa ukuchithwa kwamandla ombane.
Yintoni ukukhuselwa kwe-flashover I-Flashover ibhekisela kwinto yokukhutshwa kunye nomphezulu we-insulator eqinile xa i-gas okanye i-dielectric engamanzi ejikeleze i-insulator eqinile iphukile.Isiganeko.Ukusetyenziswa kokhuseleko lwe-flashover Ukhuseleko lwe-flashover lunokulungelelanisa i-voltage ye-flashover kwiimeko ezahlukeneyo.Ngokomzekelo, xa usebenzisa i-resonance yochungechunge ukuqhuba i-AC yokumelana nombane kwisixhobo sombane esine-voltage ephezulu njengeentambo kunye neziguquli, i-flashover voltage inokulungelelaniswa ngokukhululekileyo.
Xa i-voltage yokumelana ne-AC isetiwe, kuyafaneleka ukuseta i-flashover voltage kwi-6 ~ 8kv.Kufanelekile ukuseta ukhuseleko lwe-flashover yezixhobo zombane ezingama-35kv ukuya kwi-10.5kv.Ukuba i-voltage yokukhusela i-flashover isetyenziswe kakhulu okanye incinci kakhulu, iya kunika impendulo kwimeko yokwenyani yento evavanyiweyo.ezinempembelelo.Ukongeza, ukukhuselwa kwe-flashover kukwachatshazelwa ngumgama kunye nomswakama.Umzekelo, amandla ombane aphezulu kwindawo efumileyo kulula ukukhupha ukufuma emoyeni.Ukuba i-voltage yokukhusela i-flashover iphantsi kakhulu ngeli xesha, ukukhuselwa kwe-flashover kulungele ukwenzeka rhoqo kwaye akunakuvavanywa.Ukuba iphezulu kakhulu, xa ukhuseleko lwe-flashover lwenzeka, lukhusela ngokuthe ngqo ukhuseleko lwe-flashover yento evavanyiweyo.
Indlela yokuchaza i-voltage ye-flashover iyahluka ukusuka kumenzi ukuya kumenzi, ezinye zisetwa ngokuzenzekelayo ngokobudlelwane obulinganayo kunye nombane wokuvavanya, kwaye ezinye zichazwe ngesandla ngumsebenzisi.Kuseza kubakho iingxaki, kwaye mna ndicinga ukuba useto lwezandla lungcono.Yintoni endimele ndiyenze emva kokukhusela i-flashover?Musa ukuqhubeka ukulinganisa emva kokuba ukhuseleko lwe-flashover lwenzeka, qhawula umbane wesixhobo sokuvavanya, khangela umgama wokhuseleko wecandelo ngalinye kunye ne-node, ulungelelanise umgama ukuba umgama usondele kakhulu, uze usebenzise i-5000V ukuxhathisa ukulinganisa ukulinganisa i-Ground insulation. ukuchasana, ukuba ukuchasana kwe-insulation kungaphantsi kwe-0.5MΩ, ngoko ikhebula linokuba nephutha lokuphuka.Ngeli xesha, uvavanyo oluphezulu lwe-voltage alukwazi ukuphinda lwenziwe, ngaphandle koko umlinganiselo unokuqhubeka.
