Mukuru

Rudzi rweZinc OxideKubata Kukwirandiyo inodzivirira magetsi zvakanyanya pamagetsi emagetsi emhando yepamusoro uye mudziyo wechiteshi chemagetsi. Yakabatanidzwa ne zinc oxide nedzimwe metal oxide se core resistor disc, hunhu hwe volt-ampere uye kugona kwe resistor disc kwakawedzera zvakanyanya kana tichienzanisa neSiC type surge arrester.

Pasi pemagetsi ekushanda, magetsi anopinda nepa surge arrester anongori ma micro-ampere grade chete. Kana surge arrester ikasangana ne over-voltage, resistor disc ine hunhu hwakanaka husina kurongeka inowedzera magetsi anopinda nepa surge arrester kusvika kuzviuru zveampere ipapo ipapo. Surge arrester inenge iri mu conducting state uye inobva yaburitsa simba rayo rakawandisa panyika uye nokudaro inodzivirira simba re transmission kubva pakukanganiswa ne over-voltage.

Kushanda Kwehunyanzvi:

Kushanda kwechigadzirwa kunoenderana nezvinodiwa zvehunyanzvi zveIEC60099-4, IEEE.C62.11.

Nzvimbo Yekushandisa:

1. Tembiricha yekunze: -40℃ ≤T≤40℃
2. Kureba pamusoro pegungwa: ≤1000m
3. Mhepo inomhanyisa zvakanyanya: ≤ 35m/s
4. Kuwanda kwekudengenyeka kwenyika: ≤8
5. Kuwanda (AC system): 50/60Hz
6. Voltage yemagetsi inoshandiswa kwenguva refu ≤ Voltage inoshanda nguva dzose Kusvibiswa kwakanyanya kunofanirwa kuratidzwa usati waraira.
