SPD isipele umvikeli T2 uchungechunge

Umbiko jikelele wemkhicito

Ngekusho kwe-GB18802.1, GB50057 kanye ne-Q / THQBOO1-2013 emazinga, ekupheleni kwangaphambili kwe-SPD loop kumele kuxhunywe ngechungechunge ngetintfo tekuvikela te-overcurrent letidzingwa ngumkhiciti wekuvikela kwe-surge. kuyawohloka futsi kwehluleka, 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:

 

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 besicelon

 

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.

 

Timphawu temkhicito

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.
