Isivikelo se-SPD esiyisipele se-T2 uchungechunge

Ukubuka konke komkhiqizo

Ngokwezindinganiso ze-GB18802.1, GB50057 kanye ne-Q/THQBOO1-2013, ingxenye engaphambili ye-SPD loop kumele ixhunywe ngokulandelana nemishini yokuvikela i-overcurrent edingwa umenzi wesivikelo se-surge. Ngenxa yokuthi i-fuse yamanje kanye ne-miniature circuit breaker azikwazi ukuhambisana ne-SPD, lapho ukunikezwa kwamandla kungavamile noma i-SPD yonakala futhi yehluleka, umlilo kanye nemishini kuyalimala ngenxa yombani, okuthinte kakhulu ukusebenza okuvamile kokukhiqiza!

Njengamanje, inani elikhulu lama-miniature circuit breaker asetshenziswa kanye ne-SPD alikwazi ukufaniswa kula maphuzu amane alandelayo:

 

Ngenxa yesimo samanje sokuthi akukho divayisi yokuvikela i-overcurrent esekela i-SPD ethile embonini yokuvikela umbani, ngemuva kweminyaka emithathu yocwaningo nentuthuko kanye nokuhlolwa okuhlukahlukene kokulingisa kwemvelo okungaphezu konyaka owodwa elabhorethri, kufakazelwe ukuthi i-SPD backup protector (SCB) iyasebenza.

1. Imvamisa yamandla e-SPD inani lohambo lokuhamba nge-freewheeling 4A

2. Ugesi we-non-trip impulse mkhulu kune-40kA (8/20);

3. Ukucindezeleka okusalayo kokukhanya kwe-Lightning impulse. Xazulula ngokuphelele isimo samanje sokuthi i-SPD ayinazo izinto zokuvikela ezisebenza ngokweqile; Umphumela oqondile wokubambisana phakathi kwe-SCB ne-SPD ukuqinisekisa ukuthi i-SPD ayibambi umlilo futhi umthelela wamanje wokukhanya awukhubeki.

 

Umsebenzi kanye nobubanzi bokusetshenziswan

 

Isixhumi sangaphandle esikhethekile se-SPD sixhunywe ochungechungeni ku-SPD loop, futhi idivayisi yangaphakathi yokuhlunga yamanje isetshenziselwa ukwenza imvamisa yamandla ikhefu elisheshayo lamanje elincane; Umthelela wombani wamanje ophezulu awukhubeki. Ukufeza umsebenzi wokuvikela umlilo wamanje omncane we-SPD kanye nokuvikela okuqhubekayo kwe-SPD komthelela wombani; Imikhiqizo ye-SCB isetshenziselwa kuphela ukuvikela i-SPD loop overcurrent, noma ukuvikela kwamanje okusekelayo. Sicela ungazisebenzisi kwezinye izikhathi.

 

Izici zomkhiqizo

1. Indlela yokukhubeka elawulwa yipharamitha, engafinyelela ekuqhekekeni okukhethiwe kwamanje;

2. I-voltage eseleyo yamanje we-impulse iphansi, engaqhathaniswa neye-fuse;

3. Ukuxhumana okunamandla aphezulu, okunempilo ende yenkonzo;

4. Isimo esiphukile kancane, ivolumu encane, elula ukwehluleka kwamandla ukuthola i-SPD;

5. Ukucaciswa okuphelele, okuhlangabezana nezidingo zokusekela i-SPD emazingeni e-T1, T2 kanye ne-T3.

Ukufakwa kwesitimela se-clamp esingu-6.35mm kuhlangabezana nezidingo zokufakwa emhlabeni wonke.
