GDPD-306M Portable Ultrasonic Partial Discharge Detector
GDPD-306M imagwiritsidwa ntchito kwambiri pozindikira kutulutsa pang'ono kwamagetsi.Kuphatikizira ma switchgear okwera kwambiri, ma ring mains, voltage/transformer yapano, thiransifoma (kuphatikiza chosinthira chamtundu wouma), GIS, mizere yam'mwamba, zingwe, ndi zida zina zodziwikiratu.
Zizindikiro zotsatirazi zimagwiritsidwa ntchito kuyeza kuchuluka kwa kutulutsa kwa zida zamagetsi:
Kuzindikira kwapang'onopang'ono kwapang'onopang'ono: Poyesa chizindikiro chotulutsa mphamvu pafupipafupi, kuchuluka kwa kutulutsa kwapang'onopang'ono kumadziwika molingana ndi kuchuluka kwamtengo wapatali (dB) pakutsatizana kwa pulse.
Kuzindikira pafupipafupi kwa kutulutsa kwapang'onopang'ono: Chipangizochi chimayesa chizindikiro chotuluka mkati mwa kuzungulira kwamagetsi, chimatulutsa ma pulses ndikuwonetsetsa kuchuluka kwa kutulutsa pang'ono malinga ndi kuchuluka kwa ma pulses otulutsa.
●Ndi masensa osiyana kukwaniritsa tsankho kumaliseche kudziwika pafupifupi onse zida zamagetsi.
●Perekani njira zingapo zotsatsira monga mawonekedwe a nthawi-domain, PRPD, PRPS, ndi zina zotero, kuti muzindikire kusanthula kwa mitundu yosiyanasiyana yotulutsa.
●Mawonekedwe osavuta kugwiritsa ntchito makina a munthu amathandizira kasamalidwe ka data pazida zosiyanasiyana, kuphatikiza kutsatiridwa kwa zomwe zidasintha zakale, kusanthula kwa data kopingasa komanso koyima, ndikuzindikira kuzindikira kwatsatanetsatane kwa chipangizocho choyesedwa.
●Ma sensor opangidwa ndi akupanga ndi mphamvu yapadziko lapansi (yotchedwa TEV) sensor, imathanso kulumikizidwa ndi masensa apadera akunja a ma transfoma, GIS, mizere yakumtunda, ndi zingwe.
●Imatengera njira yodziwikiratu yosasokoneza, palibe chifukwa chozimitsa panthawi yoyeserera, palibe chifukwa chokonzekera gwero lamagetsi owonjezera, ndilosavuta kugwiritsa ntchito kuposa chowunikira chachikhalidwe cha pulsed partial discharge.
●Mayeso amtundu wa bandwidth ndi 30kHz ~ 2.0GHz, oyenera kuzindikira mfundo zamagulu osiyanasiyana.
