Umsebenzi
Isibambisi sixhunywe phakathi kwekhebula nomhlabathi, ngokuvamile ngokuhambisana nezinto ezivikelwe.Umbopheli angakwazi ukuvikela ngokuphumelelayo imishini yokuxhumana.Uma kwenzeka i-voltage engavamile, isibambisi sizosebenza futhi sidlale indima yokuvikela.Uma ikhebula lokuxhumana noma izinto zokusebenza zisebenza ngaphansi kwe-voltage evamile yokusebenza, isibambisi ngeke sisebenze, futhi sithathwa njengesifunda esivulekile phansi.Uma i-voltage ephezulu seyenzekile futhi ukufakwa kwezinto ezivikelwe kusengozini, isibambisi sizothatha isinyathelo ngokushesha ukuze siqondise amandla okushisa aphezulu afinyelela phansi, ngaleyo ndlela abeke umkhawulo we-voltage amplitude futhi avikele ukufakwa kwezintambo zokuxhumana nezinto zokusebenza.Lapho i-overvoltage inyamalala, isiboshwa sibuyela ngokushesha esimweni saso sokuqala, ukuze umugqa wokuxhumana usebenze ngokujwayelekile.
Ngakho-ke, umsebenzi oyinhloko wokubopha ukusika igagasi lokugeleza elihlaselayo futhi unciphise inani le-overvoltage yezinto ezivikelwe ngokusebenzisa umsebenzi wegebe lokukhishwa elihambisanayo noma i-resistor nonlinear, ngaleyo ndlela kuvikela ulayini wokuxhumana kanye nemishini.
Izinqamuli zombani zingasetshenziswa hhayi kuphela ukuvikela ngokumelene nama-voltage aphezulu akhiqizwa umbani, kodwa futhi ukuvikela ngokumelene nokusebenza kwamandla aphezulu.
