Makhalidwe a Anthu Ogwira Ntchito Zachizolowezi

1. Mphamvu yapano ya zinc oxide arrester ndi yayikulu
Izi zimaonekera makamaka mu kuthekera kwa zomangira mphezi kuyamwa ma voltage osiyanasiyana a mphezi, ma voltage opitilira nthawi yamagetsi, ndi ma voltage ogwiritsira ntchito. Mphamvu yamagetsi ya zinc oxide yomwe imapangidwa ndi Chuantai imakwaniritsa kapena kupitirira zomwe zimafunikira pa miyezo ya dziko. Zizindikiro monga mulingo wotulutsa mzere, mphamvu yoyamwa mphamvu, kulekerera kwamphamvu kwa 4/10 nanosecond, ndi mphamvu yamagetsi ya 2ms square wave yafika pamlingo wotsogola wapakhomo.

2. Makhalidwe abwino kwambiri a chitetezo cha zinc oxide arresters
Chogwirizira cha zinc oxide ndi chinthu chamagetsi chomwe chimagwiritsidwa ntchito kuteteza zida zamagetsi zosiyanasiyana mu dongosolo lamagetsi ku kuwonongeka kwa mphamvu yochulukirapo, ndipo chili ndi magwiridwe antchito abwino oteteza. Chifukwa mawonekedwe a volt-ampere osakhala a mzere wa zinc oxide valve plate ndi abwino kwambiri, kotero kuti ma microampere current ochepa okha ndi omwe amatha kudutsa pansi pa mphamvu yogwira ntchito, ndikosavuta kupanga kapangidwe kopanda mipata, kotero kuti kali ndi magwiridwe antchito abwino oteteza, kulemera kopepuka, komanso kukula kochepa. Pamene mphamvu yochulukirapo ikulowa, mphamvu yodutsa mu valavu imawonjezeka mwachangu, ndipo nthawi yomweyo kutalika kwa mphamvu yochulukirapo kumakhala kochepa, ndipo mphamvu ya mphamvu yochulukirapo imatulutsidwa. Pambuyo pake, mbale ya valve ya zinc oxide imabwerera ku mphamvu yolimba kwambiri, kotero kuti mphamvu yamagetsi imagwira ntchito bwino.

3. Kutseka kwa zinc oxide arrester ndi kwabwino
Chogwirizira chimagwiritsa ntchito jekete lapamwamba kwambiri lokhala ndi magwiridwe antchito abwino komanso mpweya wabwino, komanso miyeso monga kuwongolera kukanikiza kwa mphete yotsekera ndi kuwonjezera sealant. Jekete la ceramic limagwiritsidwa ntchito ngati chotchingira kuti zitsimikizire kutseka kodalirika komanso kugwira ntchito kokhazikika kwa chogwirizira.

4. Kapangidwe ka makina a zinc oxide arresters
Ganizirani makamaka zinthu zitatu izi:
⑴ Mphamvu ya chivomerezi;
⑵Mphepo yamphamvu kwambiri yomwe imagwira ntchito pa chogwirira
⑶ Mbali ya pamwamba ya chogwirira ntchito imakhala ndi mphamvu yokwanira yovomerezeka ya waya.

5. Kugwira ntchito bwino kwa zinc oxide arrester
Choletsa zinc oxide chopanda mipata chili ndi mphamvu yolimbana ndi kuipitsa mpweya.
Mlingo wa mtunda wa creepage womwe wafotokozedwa ndi muyezo wa dziko lonse ndi:
⑴Kalasi II malo oipitsa mpweya: mtunda woyenda pansi 20mm/kv
Malo oipitsidwa kwambiri a ⑵ III level: mtunda woyenda pansi pa madzi 25mm/kv
⑶ Giredi IV, malo oipitsidwa kwambiri: mtunda woyenda pansi ndi 31mm/kv

6. Kudalirika kwakukulu kwa zinc oxide arresters
Kudalirika kwa ntchito kwa nthawi yayitali kumadalira mtundu wa chinthucho komanso ngati kusankha kwa chinthucho kuli koyenera. Ubwino wa zinthu zake umakhudzidwa kwambiri ndi zinthu zitatu izi:
A. Kumveka bwino kwa kapangidwe kake konse ka womangira;
Makhalidwe a B Volt-ampere ndi makhalidwe a kukana ukalamba kwa ma valve a zinc oxide
C Kutseka kwa chogwirira.

7. Kulekerera kwa mafupipafupi a mphamvu
Chifukwa cha zifukwa zosiyanasiyana monga kukhazikika kwa gawo limodzi, mphamvu yayitali komanso kutaya katundu mu dongosolo lamagetsi, izi zingayambitse kukwera kwa magetsi othamanga kapena kupanga magetsi opitilira muyeso okhala ndi mphamvu zambiri. Chogwirizira chimatha kupirira mphamvu inayake mkati mwa nthawi inayake. Mphamvu imawonjezera mphamvu.
