Abavelisi kunye nabathengisi bezixhobo zokukhupha iigesi ezingasebenziyo zaseTshayina

Isixhobo sokukhupha esingenanxalenye Umfanekiso obonisiweyo

Inkcazo emfutshane:

Isixhobo sokubona i-PD sisetyenziswa kakhulu kwi-power transformer, i-HV CT/PT, i-arrester, i-HV switch, iintambo ze-HV XLPE, njl. Uvavanyo lusekelwe kwinkcazo yokulinganisa itshaja ebonakalayo njengoko kubonisiwe kwi-IEC 270. Itshaja elinganisiweyo iveliswa yi-input impulse ye-capacitor ye-100pF. I-voltage ye-10mV yesinyathelo ithetha ukukhutshwa okungaphelelanga kwe-1pC kwaye ixesha lokunyuka kwe-voltage yesinyathelo lingaphantsi kwe-50ns.

Iinkcukacha zeMveliso

Uvavanyo lwe-PD lolona vavanyo luphambili lokufakelwa kwezixhobo zombane, kwaye ukukhutshwa okungaphelelanga luphawu olubalulekileyo lomgangatho wezixhobo zombane. Isixhobo sokubona sisekelwe kwi-modularization, siyila iindawo zokulinganisa njengemodyuli eqhelekileyo ngokwemisebenzi eyahlukeneyo. Iimodyuli zingongezwa okanye zicinywe ngokweemfuno zabasebenzisi. Imodyuli iluhlobo oluqhelekileyo lwaseYurophu, olulungele ukugcinwa nokuhlaziywa. Yamkela inkqubo yenkqubo yehardware ephucukileyo, kunye nekhadi le-NI elivela kwi-America National Instrument. Ikwasebenzisa isixhobo sokucoca sedijithali kunye nezinye izixhobo zenkqubo yesignali ukuqokelela nokuhlalutya isignali ye-PD.
