Yintoni iSixhobo soKhuselo lokuKhuphuka?

Isixhobo sokukhusela ukuvuza sikhusela iinkqubo zombane kwi-overvoltage edlulayo ebangelwa ngumbane, imisebenzi yokutshintsha, okanye ukuphazamiseka kwegridi, okuthintela ukungaphumeleli kokufakwa kobushushu kunye nomonakalo wezixhobo.

Isixhobo sokukhusela ukuvuza (i-SPD) sifakwa ngaxeshanye nesekethe yamandla. Phantsi kwevolthi eqhelekileyo, ayisebenzi. Xa ivolthi idlula umda ochaziweyo, i-SPD itshintshela kwimeko ye-low-impedance kwaye iqondisa kwakhona umsinga wokuvuza emhlabeni. Olu tshintsho lwenzeka kwimizuzwana emincinci, ngokukhawuleza kakhulu kunee-circuit breakers okanye ii-fuses.

Izixhobo zokukhusela ukugquma zisetyenziswa kakhulu kwezi:

• Iibhodi zokusasazwa kwemizi-mveliso

• Iikhabhathi zolawulo kunye neephaneli ze-PLC

• Iinkqubo zamandla elanga nawomoya
