Umsebenzi

Umbambeli uqhagamshelwe phakathi kwentambo kunye nomhlaba, ngokuqhelekileyo ngokuhambelana nezixhobo ezikhuselweyo.Umbambisi unokukhusela ngokufanelekileyo izixhobo zonxibelelwano.Nje ukuba kubekho amandla ombane angaqhelekanga, umbambeli uya kwenza kwaye adlale indima yokukhusela.Xa ikhebula lonxibelelwano okanye izixhobo zisebenza phantsi kombane osebenzayo oqhelekileyo, umbambeli akayi kusebenza, kwaye uthathwa njengesiphaluka esivulekileyo emhlabeni.Nje ukuba kubekho amandla ombane aphezulu kwaye ukugqunywa kwezixhobo ezikhuselweyo kusengozini, umbambeli uya kuthatha inyathelo ngoko nangoko ukukhokela i-high-voltage surge yangoku emhlabeni, ngaloo ndlela enciphisa i-voltage amplitude kunye nokukhusela ukugqunywa kweentambo zonxibelelwano kunye nezixhobo.Xa i-overvoltage inyamalala, umbambisi ubuyela ngokukhawuleza kwisimo sawo sokuqala, ukwenzela ukuba umgca wonxibelelwano usebenze ngokuqhelekileyo.

Ngoko ke, umsebenzi oyintloko wokubanjwa kukunqumla i-wave wave ehlaselayo kunye nokunciphisa ixabiso elingaphezulu kwe-overvoltage yezixhobo ezikhuselweyo ngomsebenzi we-gap yokukhupha i-parallel okanye i-resistor nonlinear, ngaloo ndlela ikhusela umgca wonxibelelwano kunye nezixhobo.

Izithinteli zombane zingasetyenziselwa ukukhusela kuphela kumbane ophezulu owenziwe ngumbane, kodwa kunye nokukhusela ekusebenzeni kombane ophezulu.

Ulwazi oluSisiseko lokuBambisa uMbane

Ingcaciso: Inokukhulula umbane okanye zombini inkqubo yamandla esebenza ngamandla ombane, ikhusele izixhobo zombane kwi-overvoltage edlulayo (i-overvoltage yombane, i-overvoltage yokusebenza, i-frequency frequency transient overvoltage shock), kwaye inokunqumla i-freewheeling ngaphandle kokubangela isixhobo sombane esibangela ukuba isekethe emfutshane umhlaba wenkqubo.

Umsebenzi: Xa i-overvoltage isenzeka, i-voltage phakathi kwee-terminals ezimbini zombanjwa ayigqithisi ixabiso elichaziweyo, ukwenzela ukuba izixhobo zombane zingonakaliswa ngokugqithisa;emva kokuba i-overvoltage isetyenzisiwe, inkqubo inokubuyela ngokukhawuleza kwisimo esiqhelekileyo ukuqinisekisa ukunikezelwa kwamandla okuqhelekileyo kwenkqubo.

Iimpawu ezininzi ezibandakanyekayo kwisibambi samandla
(1) Uphawu lweVolt-yesibini: lubhekisa kubudlelwane obuhambelanayo phakathi kwamandla ombane kunye nexesha.
(2) I-Power frequency freewheeling: ibhekiselele kumbane ojikelezayo ojikelezayo emva kokuphela kwamandla ombane okanye ukukhutshwa kombane ogqithileyo, kodwa amandla ombane ombane asasebenza kumbambeli.
(3) Ukukwazi ukuzibuyisela amandla e-dielectric: ubudlelwane phakathi kwamandla e-dielectric yezixhobo zombane kunye nexesha, oko kukuthi, isantya sokubuyisela kumandla e-dielectric yasekuqaleni.
