Uhlobo lwe-2 AC Surge Protection Device SPD
I-DlN-rail type AC SPD yedivayisi yokuvikela ukukhuphuka kwama-pole amaningi (i-SPD) - uchungechunge lwe-LKX-C40
I-LKX-C series type2 AC SPD ihlangabezana nokuhlolwa kwe-Class II (8/20 μs waveform) futhi inikeza isici sokufaka isignali esikude esingakhethwa esibangela i-alamu ekude.
Imininingwane:
● I-voltage ejwayelekile [Un]: 220V 300V 380V 400V
● Amandla aphezulu, i-voltage yokusebenza eqhubekayo [Uc]: 275V 320V 385V 440V

Ingabe ama-SPD angazivikela kuzo zonke izinhlobo zokuphazamiseka kukagesi?
Ama-SPD aklanyelwe ukuvikela ekukhuphukeni okuningi kwesikhashana, kodwa anemikhawulo ngokusekelwe esilinganisweni sawo. Angase angavikeli ngokugcwele ekukhuphukeni kwamandla aphezulu kakhulu noma ekushayweni kombani okuqondile uma idivayisi ingakalwanga ngokufanele. Ukuze kuvikelwe ngokuphelele, kungasetshenziswa inhlanganisela yezinhlobo ezahlukene ze-SPD.
Umehluko phakathi kwe-Type 1, Type 2 Protection Device SPD
Uhlobo 1 lwe-SPD iklanyelwe ukusingatha ukukhuphuka kwamandla kagesi okuguquguqukayo okunamandla aphezulu, okuvame ukubangelwa ukushaya kombani okuqondile. Lawa madivayisi avame ukufakwa emnyango omkhulu wokunikezwa kwamandla wesakhiwo, enikeza isivikelo esiyinhloko ezimweni ezinjalo ezimbi kakhulu. Ama-SPD ohlobo 1 ayakwazi ukuphatha amaza okuqhuma afinyelela ku-100 kA noma ngaphezulu, esebenzisa izingxenye zokuvikela ezinamandla aphezulu njengezibambi zomoya ukuqinisekisa ukuthi uhlelo luvikelwe ngesikhathi sokukhuphuka okukhulu.
Uhlobo 2 lwe-SPD inikeza isivikelo sezingxenye zokusatshalaliswa kohlelo lukagesi, ibhekana nokukhuphuka okusele okungenzeka kusekhona ngemva kokuvikelwa kohlobo 1. Uma ifakiwe kumaphaneli okusabalalisa noma kumaphaneli amancane, ama-SPD ohlobo 2 aklanyelwe ukuphatha amaza okuqhuma aphansi, ngokuvamile afinyelela ku-20-40 kA ngesigaba ngasinye. Lawa madivayisi afaka izingxenye ezifana ne-Metal Oxide Varistors (MOVs) noma ama-Gas Discharge Tubes (GDTs) ukuze ahlinzeke ngesivikelo esanele semishini elandela isivikelo sokuqhuma okuyinhloko.
I-T1+T2 SPD ihlanganisa izinzuzo ze-Type 1 kanye ne-Type 2 SPDs, ihlinzeka ngokuvikelwa okuphelele kulo lonke uhlelo lukagesi. Ngokufaka i-Type 1 SPD emnyango omkhulu wamandla ukubhekana nokwanda kwamandla aphezulu kanye ne-Type 2 SPD ngaphakathi kohlelo lokusabalalisa ukuze kuvikelwe okwesibili, ama-T1+T2 SPDs aqinisekisa ukuzivikela okuqinile ngokumelene nobubanzi bokwanda kwamandla. Le ndlela ehlanganisiwe ilungele izindawo ezinobungozi obukhulu njengezikhungo zedatha, izibhedlela, kanye nezindawo zezimboni, lapho ukuvikelwa kokwanda kwamandla kubalulekile khona.
Uma kudingeka amadivayisi amaningi okuvikela ukukhuphuka (ama-SPD) ukuze kuvikelwe ukufakwa, kubalulekile ukuthi ahlanganiswe ukuze asebenze kahle ndawonye. Uma ama-SPD evela kubakhiqizi abahlukene, kubalulekile ukuhlola ukuthi ayahambisana yini. Umfakisi kanye nabakhiqizi bamadivayisi bayimithombo engcono kakhulu yeseluleko sokuqinisekisa ukuthi ama-SPD azosebenza kahle ngokubambisana.
Iyini i-Surge Protective Device (ama-SPD)?
Idivayisi Yokuvikela Ukukhuphuka (i-SPD), eyaziwa nangokuthi isivikelo sokukhuphuka, yenzelwe ukuvikela amadivayisi kagesi ekukhuphukeni kwamandla kanye nokukhuphuka kwamandla okudlula kwesikhashana. Isebenza njengengxenye ebalulekile ohlelweni lokuvikela ukufakwa kukagesi. I-SPD ixhunywe ngokuhambisana nesekethe yokunikezwa kwamandla yemithwalo eyivikelayo, okusho ukuthi ingasetshenziswa emazingeni ahlukahlukene enethiwekhi yokunikezwa kwamandla. Uma ixhunywe ngokuhambisana, i-SPD ibonisa ukuvinjelwa okuphezulu ngaphansi kwezimo ezijwayelekile. Kodwa-ke, lapho kwenzeka ukuvinjelwa kwamandla okudlula kwesikhashana, ukuvinjelwa kwe-SPD kuyancipha, okuvumela ukuthi ugesi wokukhuphuka udluliselwe kudivayisi futhi kude nemishini ebucayi. Le nqubo isiza ukuvimbela ukulimala kwe-elekthronikhi eyigugu ngokuqinisekisa ukuthi amandla okukhuphuka ngokweqile aphathwa ngokuphephile.
