Ukukhuselwa kwe-Surge kubini amandla kunye nemigca yesignali yindlela eneendleko zokunciphisa ixesha lokuphumla, ukwandisa inkqubo kunye nokuxhomekeka kwedatha, kunye nokuphelisa umonakalo wezixhobo obangelwa yi-transients kunye ne-surges.Ingasetyenziselwa naluphi na uhlobo lwesibonelelo okanye umthwalo (1000 volts nangaphantsi).Le ilandelayo yimizekelo yokusetyenziswa kwe-SPD kumashishini, kushishino, nakumacandelo okuhlala:

Iikhabhinethi zokulawula, abalawuli beengqondo ezicwangcisiweyo, abalawuli beemoto ze-elektroniki, ukujongwa kwezixhobo, iisekethe zokukhanyisa, i-metering, izixhobo zonyango, imithwalo ebalulekileyo, amandla okugcina, i-UPS, kunye nezixhobo ze-HVAC zonke ziyimizekelo yokuhanjiswa kwamandla.

Iisekethe zonxibelelwano, iintambo zomnxeba okanye zefeksi, iifidi zeTV zentambo, iisistim zokhuseleko, iisekhethi ze-alarm, iziko lokuzonwabisa okanye izixhobo zestereo, ikhitshi okanye izixhobo zasekhaya.

IiSPD zichazwa ngolu hlobo lulandelayo yi-ANSI/UL 1449:

Uhlobo lwe-1: Idibaniswe ngokusisigxina, eyenzelwe ukudibanisa i-second ye-transformer yenkonzo kwicala lomgca wenkonzo yokuqhawula i-overcurrent device (izixhobo zenkonzo).Umsebenzi wabo ophambili kukukhusela amanqanaba okugquma kwesixokelelwano sombane ukusuka kumaza angaphandle abangelwa ngumbane okanye usetyenziso lwebhanki ye-capacitor.
Uhlobo lwesi-2: Uqhagamshelwe ngokusisigxina kwicala lomthwalo wenkonzo qhawula isixhobo esisebenza ngokungaphaya (isixhobo senkonzo), kubandakanywa neendawo zephaneli yophawu.Eyona njongo iphambili yaba bakhuseli botyando kukukhusela izinto zombane ezibuthathaka kunye nemithwalo esekwe kwi-microprocessor ukusuka kumandla ombane ashiyekileyo, utyando oluveliswa ziimoto, kunye nezinye izehlo zotyando ezenziwe ngaphakathi.

Uhlobo lwe-3: Kwi-Point-Point-Of-Use Ukusuka kwipaneli yenkonzo yombane ukuya kwindawo yokusetyenziswa, ii-SPD kufuneka zakhiwe ngobude obuncinci bomqhubi weemitha ezili-10 (iinyawo ezingama-30).Ii-SPD ezidityaniswe ngentambo, iplagi ethe ngqo, kunye nohlobo lokwamkela yimizekelo.

Uhlobo lwe-4 : I-SPD (i-Component Recognised) iNdibano yeCandelo -- Ezi ndibano zecandelo zenziwe ngecandelo elinye okanye ngaphezulu kwe-5 ye-SPD, kunye ne-disconnector (ngaphakathi okanye ngaphandle) okanye indlela yokudlulisa i-UL 1449, iCandelo 39.4 elilinganiselweyo langoku. iimvavanyo.Ezi ziindibano zeSPD ezingagqitywanga eziqhele ukubekwa kuluhlu lwezinto zokusetyenziswa kokuphela ukuba zonke iiparamitha zokwamkelwa zidibene.Ezi ndibano zecandelo le-4 azivumelekanga ukuba zifakwe kwintsimi njenge-SPD ezimeleyo ngenxa yokuba aziphelelanga njenge-SPD kwaye zifuna uviwo olongezelelweyo.Ukhuseleko lwangoku lufuneka rhoqo kwezi zixhobo.

Uhlobo lwe-5 SPD (i-Component Recognized) - I-Discrete component surge protection devices, njenge-MOVs, enokuthi ifakwe kwibhodi yesiphaluka eprintiweyo kwaye idibaniswe nezikhokelo zabo, okanye ezinokuthi zigcinwe kwindawo evalelekileyo kunye nokupheliswa kwee-wiring.Ezi zixhobo zoHlobo lwe-5 SPD azanelanga njenge-SPD kwaye kufuneka zihlolwe ngakumbi ngaphambi kokuba zibekwe entsimini.Uhlobo lwe-5 SPDs luqeshwe ngokuqhelekileyo kuyilo kunye nokwakhiwa kwee-SPD ezipheleleyo okanye iindibano ze-SPD.
