Portable Zinc Oxide Lightning Surge Arrester Discharge Counter Tester
Woyesa Mphezi Yoyeserera Mayeso a Moa
1. Zopangidwa motsatira mfundo zachitetezo
2. Mphamvu yamagetsi imatha kukhazikitsidwa
3. Sankhani ma calibration apano malinga ndi kuchuluka kwa zida zowunikira zowunikira mphezi pa intaneti, ndikuwongolera zokha
4. Mphamvu yamagetsi imadulidwa yokha muyeso utatha
5. 2 mitundu ya njira magetsi: ntchito lithiamu ion batire kupereka mphamvu, ndipo akhoza mlandu mu ntchito boma nthawi yomweyo. Mphamvu ikatha, imatha kusintha kuchoka pamagetsi a AC kupita kumagetsi a batri.
6. Ntchito yotetezera kwathunthu, dera lapadera lotulutsa mphamvu mkati mwa capacitor yosungirako mphamvu pambuyo poyesedwa.
Zodziwika bwino za Arrester Counter Tester

Kuwerengera ntchito yotsimikizira
a) Mawonekedwe amtundu waposachedwa: 8/20 US (Inrush pano ndi 8uS kuchokera pomwe idachitika kufika pachimake, 20uS kuchokera pomwe idachitika mpaka 50% pachimake), mtengo wapamwamba kwambiri: > 500A.
b) Kutulutsa mphamvu: 600V, 800V, 1000V, 1200V.
c) Nthawi zotulutsa: Nthawi za 1-30 zitha kukhazikitsidwa.
d) Kutaya nthawi: 3-30 masekondi akhoza kukhazikitsidwa.
e) Mukamaliza kutulutsa, chidacho chimangodula magetsi otulutsa, omwe ndi otetezeka komanso odalirika kuti apewe ngozi.
Ntchito calibration panopa
a) Zotulutsa zamakono: 0.1-10mA, zamakono zimangotuluka pa 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%.
b) Kulondola kwa zotulutsa: 1% + 3uA;
c) Mndandanda wazomwe zikuchitika:
Ngati kauntala panopa ndi 3mA, kutulutsa 0.3mA 0.6mA 0.9mA 1.2mA 1.5mA
1.8mA 2.1mA 2.4mA 2.7mA 3mA
