SPD backup umkhuseli T1 series
Isishwankathelo semveliso
Ngokutsho kwe-GB18802.1, i-GB50057 kunye nemigangatho ye-Q/THQBOO1-2013, isiphelo sangaphambili se-SPD loop kufuneka siqhagamshelwe kwichungechunge kunye nezixhobo zokukhusela ezigqithisileyo ezifunwa ngumenzi wokhuselo lokutya.
Ngenxa yokuba i-fuse yangoku kunye ne-miniature breaker circuit breaker ayikwazi ukulungelelanisa kunye ne-SPD, xa ukunikezelwa kwamandla kungaqhelekanga okanye i-SPD iyancipha kwaye ingaphumeleli, umlilo kunye nezixhobo zonakaliswe ngumbane, oye wachaphazela kakhulu ukusebenza okuqhelekileyo kwemveliso!
Okwangoku, inani elikhulu lezaphuli zesekethe ezincinci ezisetyenziswe ngokudibeneyo ne-SPD azikwazi ukuhanjiswa kula manqaku mane alandelayo:
I-1.Umothuko wangoku wombane kulula kakhulu ukonakalisa-ukhuseleko lombane aluphumeleli;
I-2.I-voltage ephezulu eshiyekileyo yombane we-impulse current-ukuthembeka kokukhusela umbane kwezixhobo kuyancipha;
3.I-frequency yamandla e-free-wheeling ayihambi-ubonelelo lwamandla aluqhelekanga kwaye iSPD iyavutha;
4.Impembelelo yombane ihamba ngempazamo-ukhuseleko lombane aluphumeleli.
Ngokujonga imeko yangoku ukuba akukho SPD-specific ukuxhasa isixhobo overcurrent ukhuseleko kushishino umbane ukhuseleko, emva kweminyaka emithathu yophando kunye nophuhliso kwaye ngaphezu konyaka omnye yovavanyo ezahlukeneyo zokulinganisa kokusingqongileyo elabhoratri, kungqinwe ukuba SPD umkhuseli backup. (SCB)
1.SPD amandla frequency freewheeling uhambo ixabiso 4A
2.Non-uhambo impulse current mkhulu kune 40kA(8/20);
3.Ukudandatheka okushiyekileyo kwempembelelo yombane. Sombulula ngokupheleleyo imeko yangoku yokuba i-SPD ayinazo izixhobo ezikhethekileyo zokhuseleko lwangoku; Isiphumo esithe ngqo sentsebenziswano phakathi kwe-SCB kunye ne-SPD kukuqinisekisa ukuba i-SPD ayibambi umlilo kwaye impembelelo yangoku yombane ayihambi.
Umsebenzi kunye nobungakanani besicelo
Isixhumi esikhethekileyo se-SPD sangaphandle sidityaniswe kuthotho kwi-SPD loop, kwaye isixhobo sangaphakathi sokuhlela sangaphakathi sisetyenziselwa ukuqonda amandla amaza ombane amancinci akhoyo ngoku ikhefu elikhawulezayo; Impembelelo yombane yangoku ephezulu ayihambi. Ukufezekisa umsebenzi we-frequency yamandla amancinci angoku okukhusela umlilo we-SPD kunye nefuthe lombane we-SPD ukhuseleko oluqhubekayo; Iimveliso ze-SCB zisetyenziselwa kuphela ukhuseleko lwe-SPD loop overcurrent, okanye ukhuseleko lwangoku. Nceda ungazisebenzisi kwezinye iimeko.
Uphawu lwemvelisos
1. Indlela yokukhwela elawulwa yiParameter, enokuthi ibone ukuqhawuka okukhethiweyo kumbane;
2. I-voltage eshiyekileyo ye-impulse current iphantsi, enokuthi ifaniswe neyo fuse;
3. Uqhagamshelwano oluphezulu lwamandla, kunye nobomi benkonzo ende;
4. Ubume be-Micro-broken, umthamo omncinci, ulungele ukusilela kwamandla ukubona i-SPD;
5.Iinkcukacha ezipheleleyo, ukuhlangabezana neemfuno zokuxhasa i-SPD kumanqanaba e-T1, T2 kunye ne-T3.
Ufakelo lukaloliwe olubambekayo lwe-6.35mm luhlangabezana neemfuno zofakelo kwihlabathi liphela.
