Ngaba ii-SPD zingakhusela kuzo zonke iintlobo zokuphazamiseka kombane?
Ii-SPD zenzelwe ukukhusela uninzi lweentshukumo ezidlulayo, kodwa zinemida ngokusekelwe kuvavanyo lwazo. Zisenokungazikhuseli ngokupheleleyo iintshukumo ezinamandla aphezulu kakhulu okanye ukubetha kombane ngokuthe ngqo ukuba isixhobo asilinganiswanga ngokufanelekileyo. Ukukhusela ngokupheleleyo, kungasetyenziswa indibaniselwano yeentlobo ezahlukeneyo ze-SPD.
Umahluko phakathi kohlobo 1, uhlobo 2 lwesixhobo sokukhusela i-SPD
Uhlobo lwe-1 SPD Yenzelwe ukujongana nokunyuka kwamandla ombane okuhamba kancinci, okubangelwa kukubetha kombane ngokuthe ngqo. Ezi zixhobo zihlala zifakelwa emnyango omkhulu wombane wesakhiwo, zibonelela ngokhuseleko oluphambili kwiimeko eziqatha kangaka. Ii-SPD zohlobo lwe-1 ziyakwazi ukulawula imisinga yokunyuka ukuya kuthi ga kwi-100 kA nangaphezulu, zisebenzisa izixhobo zokukhusela amandla aphezulu ezifana nezithinteli zomsantsa womoya ukuqinisekisa ukuba inkqubo ikhuselekile ngexesha lokunyuka okukhulu.
Uhlobo lwe-2 SPD Ibonelela ngokhuseleko kwiindawo zokusasazwa kwenkqubo yombane, ijongana nokugcwala okushiyekileyo okusenokuba kusekho emva kokhuseleko lohlobo 1. Zifakwe kwiiphaneli zokusasazwa okanye kwiiphaneli ezincinci, ii-SPD zohlobo 2 zenzelwe ukulawula imisinga yokugcwala esezantsi, ngokuqhelekileyo ukuya kuthi ga kwi-20-40 kA ngesigaba ngasinye. Ezi zixhobo ziquka izinto ezifana neMetal Oxide Varistors (MOVs) okanye iiGas Discharge Tubes (GDTs) ukubonelela ngokhuseleko olufanelekileyo kwizixhobo emva kokhuseleko lokuqala lokugcwala.
I-T1+T2 SPD idibanisa iingenelo ze-Type 1 kunye ne-Type 2 SPDs, inika ukhuseleko olupheleleyo kuyo yonke inkqubo yombane. Ngokufaka i-Type 1 SPD kwindawo ephambili yokungena kwamandla ukujongana nokunyuka kwamandla aphezulu kunye ne-Type 2 SPD ngaphakathi kwenkqubo yokusasaza ukhuseleko lwesibini, ii-T1+T2 SPDs ziqinisekisa ukhuselo oluqinileyo ngokuchasene noluhlu olubanzi lokunyuka kwamandla. Le ndlela idibeneyo ifanelekile kwiindawo ezinomngcipheko ophezulu ezifana namaziko edatha, izibhedlele, kunye nezakhiwo zoshishino, apho ukhuseleko olupheleleyo lokunyuka kwamandla lubalulekile.
Xa kufuneka izixhobo ezininzi zokukhusela ukuxhuzula (ii-SPD) ukukhusela ukufakelwa, kubalulekile ukuba zilungelelaniswe ukuze zisebenze kunye ngokufanelekileyo. Ukuba ii-SPD zivela kubavelisi abahlukeneyo, kubalulekile ukujonga ukuba ziyahambelana na. Umfaki kunye nabavelisi bezixhobo ngabona mthombo ubalaseleyo weengcebiso zokuqinisekisa ukuba ii-SPD ziya kusebenza ngokuchanekileyo kunye.
Yintoni iSurge Protective Device (ii-SPD)?
Isixhobo sokukhusela ukugqobhoza (i-SPD), esaziwa ngokuba sisixhobo sokukhusela ukugqobhoza, senzelwe ukukhusela izixhobo ze-elektroniki kwiintshukumo zamandla kunye nee-overvoltages zexesha elifutshane. Sisebenza njengecandelo elibalulekileyo kwinkqubo yokukhusela ukufakwa kombane. I-SPD iqhagamshelwe ngaxeshanye nesekethe yokubonelela ngombane yemithwalo eyikhuselayo, oko kuthetha ukuba ingasetyenziswa kumanqanaba ahlukeneyo enethiwekhi yokubonelela ngombane. Xa iqhagamshelwe ngaxeshanye, i-SPD ibonisa ukungqubana okuphezulu phantsi kweemeko eziqhelekileyo. Nangona kunjalo, xa kwenzeka ukungqubana kwexesha elifutshane, ukungqubana kwe-SPD kuyancipha, okuvumela ukuba umsinga wombane ujikelezwe kwisixhobo kwaye kude nezixhobo ezibuthathaka. Le nkqubo inceda ukuthintela umonakalo kwi-elektroniki ezixabisekileyo ngokuqinisekisa ukuba amandla okugqobhoza agqithisileyo alawulwa ngokukhuselekileyo.
