    Yintoni iSurge Protective Device (SPD)?

    Isixhobo sokukhusela i-Surge Protective Device (SPD) yinxalenye yenkqubo yokukhusela ukufakelwa kombane. Esi sixhobo siqhagamshela ngokuhambelana nesekethe yombane yemithwalo ekufuneka siyikhusele. Isixhobo sokukhusela i-surge siqondisa kwakhona imisinga yombane efana nomsinga wokukhupha ovela kwisekethe emfutshane. Sikwenza oko sisebenzisa unxibelelwano oluqinileyo okanye iswitshi yomoya. Ukongeza, isixhobo sokukhusela i-surge sisebenza njengesixhobo sokuvala umthwalo kwiimeko zombane ogqithisileyo kunye nesivala kwakhona esilawula inqanaba lombane ngaphezulu kombane olinganiselweyo okanye umbane ophantsi xa kukho imeko yempazamo. Singasebenzisa nesixhobo sokukhusela i-surge kuwo onke amanqanaba enethiwekhi yombane. Le ndlela idla ngokuba lolona hlobo lusetyenziswa kakhulu kwaye lusebenzayo lokukhusela i-overvoltage.

    Isixhobo sokukhusela i-Surge esidityaniswe ngaxeshanye sine-impedance ephezulu. Ngamanye amazwi, isimbuku se-series impedance silingana ne-impedance yesixhobo esinye sokukhusela i-surge. Nje ukuba i-transient overvoltage ivele ngaphakathi kwenkqubo, i-impedance yesixhobo iyancipha, ngoko ke i-surge current iqhutywa kwisixhobo sokukhusela i-surge, idlula izixhobo ezibuthathaka. Oko kukukhusela izixhobo kwi-overvoltage transients kunye nokuphazamiseka, okufana ne-voltage spikes kunye ne-electrical surges, utshintsho lwamaza, kunye ne-over-voltages ezibangelwa kukutshintsha imisebenzi okanye umbane. Xa umsebenzisi efaka i-surge strip okanye isixhobo sokukhusela i-surge kumgca wamandla ovela kwi-power utility equka ii-smoothing capacitors, ii-surge suppressors azifuneki kuba ezi capacitors sele zikhusela kutshintsho olukhawulezileyo kwinqanaba le-voltage.
