SPD isipele umvikeli T1 uchungechunge
Umbiko jikelele wemkhicito
Ngekuya kwemazinga e-GB18802.1, GB50057 kanye ne-Q/THQBOO1-2013, umphetfo wangaphambilini we-SPD loop kumele uxhunywe ngekulandzelana netintfo tekuvikela letidzingekako ngumkhiciti wekuvikela kwe-surge.
Ngenca yekutsi i-fuse lekhona nyalo kanye ne-miniature circuit breaker ayikhoni kuhambisana ne-SPD, nangabe kuphakelwa kwemandla kungakavami noma i-SPD yonakala futsi yehluleka, umlilo kanye nemishini kulinyatwa ngumbane, lokutsintse kakhulu kusebenta lokujwayelekile kwekukhicita!
Kwanyalo, inani elikhulu lama-circuit breaker lamancane lasetjentiswa ngekuhambisana ne-SPD angeke afaniswe kulamaphuzu lamane lalandzelako:
1.The umbane lamanje shock kulula kakhulu kulimata-umbane kuvikelwa kwehluleka;
2.High insalela voltage umbane impulse zamanje-kwetsembeka umbane kuvikelwa imishini kuncishiswa;
3.The amandla imvamisa khulula-wheeling akukhubeki-amandla umphakelo akuvamile kanye SPD umlilo;
4.The umbane umtselela uhambo ngephutsa-umbane kuvikelwa kwehluleka.
Ngenca yesimo lesikhona nyalo kutsi kute i-SPD-lekhetsekile lesekelako idivayisi yekuvikela ye-overcurrent embonini yekuvikela umbane, ngemuva kweminyaka lemitsatfu yelucwaningo nekutfutfukisa kanye nemnyaka longetulu kwamunye wekuhlolwa kwekulingisa kwemvelo lokuhlukahlukene elabhorethri, kufakazelwa kutsi i-SPD backup protector (SCB) .
1.SPD amandla imvamisa freewheeling luhambo inani 4A
2.Non-luhambo umfutfo lamanje mkhulu kune 40kA (8/20);
3.Umbane impulse kucindzeteleka lokusele. Kucatulula ngalokuphelele simo samanje kutsi SPD kute tintfo letikhetsekile tekuvikela over-manje; Umphumela locondzile wekubambisana emkhatsini we-SCB ne-SPD kucinisekisa kutsi i-SPD ayibambi umlilo futsi umtselela wembane wamanje awukhubeki.
Umsebenti kanye nebubanti bekusebenta
SPD disconnector ekhethekile yangaphandle ixhumeke uchungechunge ku SPD loop, kanye yangaphakathi lamanje ukuhlunga isiteshi idivayisi isetjentiswa ukuqaphela amandla imvamisa encane lamanje ikhefu esheshayo; Umtselela wembane lophakeme wamanje awukhubeki. Finyelela umsebenti amandla imvamisa encane lamanje SPD umlilo kuvikelwa kanye umbane umtselela SPD kuvikelwa lokuchubekako; Imikhicito ye-SCB isetjentiselwa kuphela kuvikelwa kwe-SPD loop overcurrent, noma kuvikelwa kwesipele samanje. Sicela ungatisebentisi kuletinye tikhatsi.
Sici semkhicitos
1. Ipharamitha-elawulwa tripping indlela, lekungabona lokukhetsiwe kwephuka nge lamanje;
2. I voltage insali impulse zamanje phansi, okuyinto kungaba kuqhathaniswa leyo fuse;
3. High-amandla uxhumane, nge impilo enkonzo eside;
4. Micro-ephukile isimo, ivolumu encane, elungele kwehluleka amandla kutfola SPD;
5.Complete imininingwane, kuhlangabetana netidzingo tekusekela SPD at T1, T2 kanye T3 emazinga.
6.35mm clamp rail kufakwa kuhlangabetana netidzingo tekufakwa emhlabeni wonkhe.
