    I-SPD yeSikhokelo sokuKhethwa kweNkqubo yokuNika amandla

    Ufakelo lwe-SPD kwindawo nganye yokhuseleko lombane, ngokomgangatho wembonakalo yombane ophantsi kwamandla ombane, yenza ulwahlulo lwezixhobo zombane ngokuhambelana nenqanaba lombane ongaphezulu, ukugqunyelelwa kwayo ukumelana nomgangatho wombane we-impulse kunokugqiba ukhetho lwe-SPD.Ngokomgangatho wenkangeleko yombane ophantsi kwamandla ombane, yenza ulwahlulo lwezixhobo zombane ngokuhambelana nenqanaba lamandla ombane angaphezulu njengenqanaba lomqondiso, inqanaba lokulayisha, inqanaba lokuhambisa kunye nolawulo, inqanaba lobonelelo lwamandla.Ukugquma kwayo ukumelana nomgangatho wombane we-impulse zezi:1500V,2500V,4000V,6000V.Ngokwendawo yokufakwa kwezixhobo ezikhuselweyo ezahlukeneyo kunye nombane owahlukileyo wangoku wezowuni yokhuseleko lombane, ukumisela indawo yofakelo lwe-SPD yonikezelo lwamandla kunye nomthamo wokuqhekeka.
    Umgama wofakelo phakathi kwenqanaba ngalinye le-SPD akufanele libe ngaphezu kwe-10m, umgama phakathi kwe-SPD kunye nezixhobo ezikhuselweyo kufuneka ube mfutshane kangangoko, ungabi ngaphezu kwe-10m.Ukuba ngenxa yothintelo lwendawo yokuhlohla, ayinakuqinisekisa umgama wofakelo, ngoko kufuneka ufakele icandelo lokuqhawula phakathi kwenqanaba ngalinye leSPD, yenza i-SPD yasemva kweklasi ikhuselwe yi-SPD yodidi lwangaphambili.Kwinkqubo yonikezelo lwamandla ombane ophantsi, ukudibanisa i-inductor kunokufezekisa injongo yokuqhawula.
    I-SPD yenkqubo yonikezelo lwamandla umgaqo wokukhetha umgaqo
    Max.Umbane oqhubekayo wokusebenza: mkhulu kunezixhobo ezikhuselweyo, ubuninzi benkqubo.umbane oqhubekayo wokusebenza.
    Inkqubo ye-TT: Uc≥1.55Uo (I-Uo yinkqubo yamandla ombane ephantsi ukuya kumgca wombane ongasebenziyo)
    Inkqubo ye-TN: Uc≥1.15Uo
    Inkqubo ye-IT: Uc≥1.15Uo(Uo yinkqubo yamandla ombane ephantsi ukuya kumbane womgca)
    Inqanaba loKhuseleko lwe-Voltage: ngaphantsi kwe-insulation ukumelana ne-voltage ye-impulse yezixhobo ezikhuselweyo
    Ukukhutshwa okulinganiselweyo ngoku: kumiselwe ngokwemeko yombane yendawo efakelweyo kunye nendawo yokukhusela umbane.
  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
