Umkhuseli we-SPD backup T1 series
Isishwankathelo semveliso
Ngokwemigangatho ye-GB18802.1, GB50057 kunye ne-Q/THQBOO1-2013, isiphelo sangaphambili se-SPD loop kufuneka siqhagamshelwe ngokulandelelana nezixhobo zokukhusela ezifunekayo ngumvelisi we-surge protector.
Ngenxa yokuba i-fuse yangoku 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 eye yachaphazela kakhulu ukusebenza okuqhelekileyo kwemveliso!
Okwangoku, inani elikhulu lee-miniature circuit breakers ezisetyenziswa kunye ne-SPD azinakulinganiswa kula manqaku mane alandelayo:
1. Ukutshayiswa kombane kulula kakhulu ukukonakalisa-ukhuseleko lombane luyasilela;
2. I-voltage ephezulu eseleyo yombane oshukumisayo-ukuthembeka kokhuseleko lombane kwizixhobo kuyancitshiswa;
3. Ukujikeleza kwamandla ngokukhululekileyo akukhubeki-umbane awuqhelekanga kwaye i-SPD iyatsha;
4. Umbane ubetha ngempazamo - ukhuseleko lombane luyasilela.
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 besicelo
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.
Uphawu lwemvelisos
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.
