General

Mtundu wa Zinc OxideKugwira Ntchito KwambiriNdi choteteza chaposachedwa kwambiri cha overvoltage cha mzere wogawa ndi chipangizo cha siteshoni yamagetsi. Chophatikizidwa ndi zinc oxide ndi metal oxide ina ngati core resistor disc, mawonekedwe a volt-ampere ndi mphamvu ya through-current ya resistor disc yakula kwambiri poyerekeza ndi SiC type surge arrester yachikhalidwe.

Pogwiritsa ntchito mphamvu yamagetsi yodziwika bwino, mphamvu yamagetsi kudzera mu surge arrester imakhala ya micro-ampere grade yokha. Pamene surge arrester ikumana ndi over-voltage, resistor disc yokhala ndi makhalidwe abwino kwambiri osalunjika imawonjezera mphamvu kudzera mu surge arrester kufika pa ma ampere zikwi zingapo nthawi yomweyo. Surge arrester imakhala mu conducting state kenako imatulutsa mphamvu ya over-voltage padziko lapansi motero imateteza chipangizo chotumizira magetsi ku mphamvu ya over-voltage.

Magwiridwe Aukadaulo:

Kugwira ntchito kwa chinthuchi kumagwirizana ndi zofunikira zaukadaulo za IEC60099-4, IEEE.C62.11.

Malo Ogwiritsira Ntchito:

1. Kutentha kozungulira: -40℃ ≤T≤40℃
2. Kutalika pamwamba pa nyanja: ≤1000m
3. Liwiro la mphepo lapamwamba kwambiri: ≤ 35m/s
4. Mphamvu ya chivomerezi: ≤8
5. Mafupipafupi (makina a AC): 50/60Hz
6. Voliyumu yamagetsi yogwiritsidwa ntchito kwa nthawi yayitali ≤ Voliyumu yogwira ntchito mosalekeza Kuipitsa kwakukulu kuyenera kuperekedwa musanayitanitse.
