Abakhiqizi nabahlinzeki bemishini yokukhipha ingxenye yaseChina

I-deck yokukhipha ingxenye Isithombe Esivelele

Incazelo emfushane:

I-PD detector isetshenziswa kakhulu kwi-power transformer, i-HV CT/PT, i-arrester, i-HV switch, izintambo ze-HV XLPE, njll. Ukuhlolwa kusekelwe encazelweni yokulinganisa ishaja ebonakalayo njengoba kuchazwe yi-IEC 270. Ishaja elinganisiwe ikhiqizwa kusuka ekufakweni kwe-input impulse ye-capacitor engu-100pF. I-voltage yesinyathelo esingu-10mV isho ukukhishwa okungaphelele okungu-1pC kanye nesikhathi sokukhuphuka kwe-voltage yesinyathelo esingaphansi kwama-50ns.

Imininingwane Yomkhiqizo

Ukuhlolwa kwe-PD kuyizinto eziyinhloko zokuhlola zokufakelwa kwemishini kagesi, kanti ukukhishwa okungaphelele kuyipharamitha ebalulekile yekhwalithi yemishini kagesi. I-detector isekelwe ekuguqulweni kwe-modular, iklama izingxenye zokulingisa njengemodyuli ejwayelekile ngokwemisebenzi ehlukene. Amamojula angangezwa noma asuswe ngokwezidingo zomsebenzisi. Imojula iwuhlobo olujwayelekile lwaseYurophu, olulungele ukulungiswa nokuvuselelwa. Isebenzisa uhlelo lwenqubo yehadiwe oluthuthukisiwe, kanye nekhadi le-NI elivela ku-America National Instrument. Isebenzisa futhi ukuhlunga kwedijithali kanye nenye idivayisi yenqubo yesignali ukuqoqa nokuhlaziya isignali ye-PD.
