1. Ababambi banamanqanaba ombane aliqela, ukusuka ku-0.38kv ombane ophantsi ukuya kwi-500kV UHV, ngelixa izixhobo zokhuselo lokutya zidla ngokuba ziimveliso zombane ophantsi kuphela;
2. Uninzi lwababambeli lufakwe kwinkqubo ephambili yokuthintela ukuhlaselwa ngokuthe ngqo kwamaza ombane, ngelixa uninzi lwabakhuseli be-surgery lufakwe kwisistim sesibini, okuyindlela eyongezelelweyo emva kokuba umbanjwa ephelisa ukuhlaselwa ngokuthe ngqo kwamaza ombane, okanye xa umbambi engalisusi ngokupheleleyo iliza lombane;
3. I-Arrester arrester isetyenziselwa ukukhusela izixhobo zombane, ngelixa i-surge protector isetyenziswa kakhulu ukukhusela izixhobo zombane okanye iimitha;
4. Ngenxa yokuba umbambeli uqhagamshelwe kwisistim sokuqala sombane, kufuneka abe nokusebenza okwaneleyo kwe-insulation yangaphandle, kwaye ubungakanani bembonakalo bukhulu kakhulu.Kuba umkhuseli wokutyanda uqhagamshelwe kumbane ophantsi, ubungakanani bunokuba buncinci kakhulu.
Isixhobo sokukhusela i-Surge 1. Ikhabhinethi yokulawula ukuguqulwa rhoqo kufuneka yongezwe;2. Ikhabhinethi yokulawula usebenzisa i-vacuum circuit breaker kufuneka yongezwe;3. Ukutshintsha okungenayo kwenkqubo yonikezelo lwamandla kufuneka kongezwe
4. Ezinye iikhabhinethi zokulawula zingenakongezwa.Ngokuqinisekileyo, ukuba kukho indawo yohlahlo lwabiwo-mali yokhuseleko, banokongezwa
Izixhobo ezikhuselayo ze-Surge ngokubanzi zahlulahlulwe zibe zimbini iintlobo: uhlobo lokhuseleko lweemoto kunye nohlobo lokhuseleko lwesikhululo samandla!
Isixhobo sokukhusela ngokulandelelana sithatha i-varistor eneempawu ezibalaseleyo ezingahambelaniyo.Phantsi kweemeko eziqhelekileyo, isixhobo sokukhusela sikwimeko ephezulu kakhulu yokuchasana, kwaye ukuvuza kwangoku kuphantse kube ngu-zero, ukuze kuqinisekiswe unikezelo lwamandla oluqhelekileyo lombambeli wenkqubo yamandla.Xa ukugqithisa kwenzeka kwinkqubo yokunikezelwa kwamandla, umhlobiso wensimbi engenasici kunye nomkhuseli wokunyuka uya kuqhuba ngokukhawuleza kwi-nanoseconds ukukhawulela i-amplitude yokugqithisa ngaphakathi kwendawo yokusebenza ekhuselekileyo yezixhobo.Ngexesha elifanayo, amandla e-overvoltage akhululwa.Emva koko, umkhuseli ngokukhawuleza uba yimeko ephezulu yokumelana, ngoko ayichaphazeli unikezelo lwamandla oluqhelekileyo lwenkqubo yamandla.
Isixhobo sokukhusela i-Surgery (SPD) sisixhobo esiyimfuneko ekukhuseleni umbane kwisixhobo sombane.Yayikade ibizwa ngokuba yi "surge arrester" okanye "overvoltage protector", ishunqulelwe njengeSPD ngesiNgesi.Umsebenzi wesixhobo sokukhusela i-surgery kukunciphisa ukugqithiswa kwe-overvoltage kumgca wamandla kunye nomgca wokuhambisa umqondiso phakathi koluhlu lwamandla ombane onokuthwala isixhobo okanye inkqubo, okanye ukukhupha umbane onamandla okhoyo emhlabeni, ukukhusela izixhobo ezikhuselweyo okanye inkqubo. ekubeni yonakaliswe yimpembelelo.
Iindidi kunye nolwakhiwo lwezixhobo ezikhuselayo zotyando zahlukile ngokweendlela ezahlukeneyo zokusebenza, kodwa kufuneka ziqulathe ubuncinci into enye yokunciphisa umbane ongeyiyo.Amacandelo asisiseko asetyenziswa kwi-SPD abandakanya i-gap yokukhupha, i-gas egcwele i-tube yokukhupha, i-varistor, i-diode yokucinezela kunye ne-coil choke.
