Umkhuseli we-SPD backup T2 series

Isishwankathelo semveliso

Ngokwemigangatho ye-GB18802.1, GB50057 kunye ne-Q/THQBOO1-2013, isiphelo sangaphambili se-SPD loop kufuneka siqhagamshelwe ngokulandelelana nezixhobo zokukhusela i-overcurrent ezifunekayo ngumvelisi we-surge protector. Ngenxa yokuba i-current fuse kunye ne-miniature circuit breaker azikwazi ukuhambelana ne-SPD, xa umbane ungaqhelekanga okanye i-SPD yonakala kwaye iyeka ukusebenza, umlilo kunye nezixhobo zonakaliswa ngumbane, nto leyo echaphazele kakhulu ukusebenza okuqhelekileyo kwemveliso!

Okwangoku, inani elikhulu lee-miniature circuit breakers ezisetyenziswa kunye ne-SPD azinakulinganiswa kula manqaku mane alandelayo:

 

Ngenxa yemeko yangoku yokuba akukho sixhobo sokukhusela umbane esixhasayo ngokukodwa kwi-SPD kwishishini lokukhusela umbane, emva kweminyaka emithathu yophando nophuhliso kunye novavanyo olungaphezulu konyaka omnye lokulinganisa okusingqongileyo kwilebhu, kuye kwafunyaniswa ukuba i-SPD backup protector (SCB)

1. Ixabiso le-SPD power frequency freewheeling trip 4A

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

3. Ukudakumba okushiyekileyo kwe-Lightning impulse. Sombulula ngokupheleleyo imeko yangoku yokuba i-SPD ayinazo izixhobo zokukhusela ezingaphaya kwamandla ombane; Isiphumo esithe ngqo sentsebenziswano phakathi kwe-SCB kunye ne-SPD kukuqinisekisa ukuba i-SPD ayibambi umlilo kwaye impembelelo yamandla ombane ayikhubeki.

 

Umsebenzi kunye nobubanzi bokusetyenziswan

 

Isixhumi sangaphandle esikhethekileyo se-SPD siqhagamshelwe kuthotho kwi-SPD loop, kwaye isixhobo sangaphakathi sokucwangcisa umjelo sisetyenziselwa ukwenza i-power frequency small current break quick; Impembelelo yombane yamandla aphezulu ayikhubeki. Ukufezekisa umsebenzi we-power frequency small current SPD fire protection kunye ne-lightning impact SPD continuous protection; Iimveliso ze-SCB zisetyenziselwa kuphela ukhuseleko lwe-SPD loop overcurrent, okanye ukhuseleko lwamandla olungasemva. Nceda ungazisebenzisi kwezinye iimeko.

 

Iimpawu zemveliso

1. Indlela yokukhubeka elawulwa yiparameter, enokwenza ukugqobhoza okukhethiweyo ngokusebenzisa umsinga;

2. I-voltage eseleyo yomsinga we-impulse iphantsi, enokuthelekiswa ne-fuse;

3. Unxibelelwano olunamandla aphezulu, olunobomi obude benkonzo;

4. Imilo ephukileyo kancinci, ivolumu encinci, ilungele ukusilela kombane ukubona i-SPD;

5. Iinkcukacha ezipheleleyo, ukuhlangabezana neemfuno zokuxhasa i-SPD kumanqanaba e-T1, T2 kunye ne-T3.

Ufakelo lwereyile ye-clamp eyi-6.35mm luhlangabezana neemfuno zofakelo kwihlabathi liphela.
