SPD isipele umvikeli T2 uchungechunge

Uhlolojikelele lomkhiqizo

Ngokuvumelana namazinga e-GB18802.1, GB50057 kanye ne-Q/THQBOO1-2013, isiphetho sangaphambili seluphu ye-SPD kufanele ixhunywe ngochungechunge nezinto zikagesi ezivikela okweqile ezidingwa umkhiqizi wesivikeli sokuhlinza.Ngenxa yokuthi i-fuse yamanje kanye ne-breaker circuit encane ayikwazi ukuxhumana nayo. I-SPD, lapho ukunikezwa kwamandla kungavamile noma i-SPD iwohloka futhi ihluleka, umlilo nemishini yonakaliswa umbani, okuye kwathinta kakhulu ukusebenza okuvamile kokukhiqiza!

Njengamanje, inani elikhulu lama-breaker circuit amancane asetshenziswa ngokuhlanganyela ne-SPD alikwazi ukumataniswa kulawa maphuzu amane alandelayo:

 

Uma kubhekwa isimo samanje sokuthi ayikho i-SPD-specific support support overcurrent device embonini yokuvikela umbani, ngemva kweminyaka emithathu yocwaningo nentuthuko kanye nonyaka owodwa wokuhlolwa okuhlukahlukene kokulingisa imvelo elabhorethri, kufakazelwa ukuthi umvikeli oyisipele we-SPD. (SCB)

1.SPD amandla ifrikhwensi freewheeling uhambo value 4A

2.Non-trip impulse current inkulu kuno-40kA(8/20);

3.Lightning impulse residual depression. Ukuxazulula ngokuphelele isimo samanje sokuthi i-SPD ayinazo izinto zikagesi ezikhethekile zokuvikela zamanje; Umthelela oqondile wokubambisana phakathi kwe-SCB ne-SPD uwukuqinisekisa ukuthi i-SPD ayibasi umlilo futhi umphumela wamanje wombani awukhubeki.

 

Umsebenzi kanye nobubanzi be-applicationn

 

Isixhumi esikhethekile sangaphandle se-SPD sixhunywe ochungechungeni ku-SPD loop, futhi idivayisi yesiteshi sokuhlunga yangaphakathi yangaphakathi isetshenziselwa ukubona imvamisa yamandla ikhefu elincane lamanje; Umthelela wombani ophezulu wamanje awukhubeki. Ukufinyelela umsebenzi wokuvama kwamandla amancane ukuvikelwa komlilo kwamanje kwe-SPD kanye nomthelela wombani we-SPD ukuvikelwa okuqhubekayo; Imikhiqizo ye-SCB isetshenziselwa kuphela ukuvikelwa kwe-SPD loop overcurrent, noma ukuvikela kwamanje kwekhophi yasenqolobaneni. Sicela ungazisebenzisi kwezinye izikhathi.

 

Izici zomkhiqizo

1. Indlela yokugibela elawulwa yipharamitha, engakwazi ukubona ukugqekeza okukhethekile;

2. I-voltage eyinsalela ye-impulse current iphansi, engaqhathaniswa ne-fuse;

3. Ukuthintana kwamandla aphezulu, impilo ende yesevisi;

4. Umumo ophukile, umthamo omncane, olungele ukwehluleka kwamandla ukuthola i-SPD;

5.Ukucaciswa okuphelele, ukuhlangabezana nezidingo zokusekela i-SPD kumazinga we-T1, T2 kanye ne-T3.

Ukufakwa kukajantshi we-clamp 6.35mm kuhlangabezana nezidingo zokufakwa emhlabeni jikelele.
