Isithinteli sokuGqibela esiKhuselekileyo sangasemva se-T

Umsebenzi weisithinteli sokunyuka koxinzelelokukukhusela izixhobo ezahlukeneyo zombane kwinkqubo yamandla kumonakalo obangelwa kukugqithisa kombane, ukugqithisela kokusebenza, kunye nokugqithisela kwamandla rhoqo. Iintlobo eziphambili zezithinteli zombane zizikhewu zokukhusela, izithinteli zeevalvu kunye nezithinteli ze-zinc oxide. Umsantsa wokukhusela usetyenziselwa ikakhulu ukunciphisa ukugqithisela komoya, kwaye ngokubanzi usetyenziselwa ukukhusela icandelo lomgca ongenayo wenkqubo yokusasazwa kombane, umgca kunye nesitishi esingaphantsi. Izithinteli zohlobo lwevalvu kunye nezithinteli ze-zinc oxide zisetyenziselwa ukukhusela izitishi ezingaphantsi kunye nezityalo zamandla. Kwiinkqubo ze-500kV nangaphantsi, zisetyenziselwa ikakhulu ukunciphisa ukugqithisela komoya. Kwiinkqubo zevolthi ephezulu kakhulu, ziya kusetyenziselwa ukunciphisa ukugqithisela kwangaphakathi okanye njenge-overvoltage yangaphakathi. Ukhuseleko olugciniweyo.

Ukusukela okoizinto zokuthintela ukuxinana kwamandlabadla ngokusebenza ngaphandle, kufuneka babe nokumelana nokuwa okunamandla, ukumelana nokutshayiswa kunye nokusebenza okungangeni manzi.

Isithinteli sokuGqibela esiKhuselekileyo sangasemva se-TIbonelela ngokhuseleko oluthembekileyo lwe-over-current kwizixhobo zombane. Icandelo layo eliphambili lisebenzisa ii-zinc oxide resistors, eziphucula kakhulu iimpawu ze-volt-ampere zee-resistors kwaye zonyusa amandla okugcina i-overvoltage xa ​​kuthelekiswa nee-silicon carbide arresters zendabuko; Isetyenziswa kakhulu kunye nesixhumi sangaphambili saseYurophu i-630A ukubonelela ngokhuseleko lwe-overvoltage kwigridi yamandla.
