ZINTHU ZISANU NDI ZIWIRI ZA ZINC OXIDE ARRESTER

1. Kuchuluka kwa madzi

Izi zimaonekera makamaka mu luso la arrester lotha kuyamwa ma overvoltage osiyanasiyana a mphezi, ma overvoltage osinthasintha a mphamvu, ndi ma overvoltage ogwirira ntchito.

2. Zinthu zotetezera

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 nonlinear volt-ampere a mbale ya valve ya zinc oxide ndi abwino kwambiri, ma microampere ochepa okha amagetsi amatha kudutsa pansi pa voltage yanthawi zonse, zomwe ndizosavuta kupanga kapangidwe kopanda mipata, kuti kakhale ndi magwiridwe antchito abwino oteteza, kulemera kopepuka komanso kukula kochepa. Pamene mphamvu yochulukirapo ikulowa, mphamvu yodutsa mu mbale ya valve 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 mkhalidwe wotsutsa kwambiri, kotero kuti makina amagetsi amatha kugwira ntchito bwino.

3. Kutseka magwiridwe antchito

Chogwirizira chimagwiritsa ntchito jekete lapamwamba kwambiri lokhala ndi magwiridwe antchito abwino komanso mpweya wabwino. Njira monga kuwongolera kupsinjika kwa mphete yotsekera ndi kuwonjezera sealant zimagwiritsidwa ntchito. Jekete la ceramic limagwiritsidwa ntchito ngati chinthu chotsekera kuti zitsimikizire kutseka kodalirika komanso kugwira ntchito bwino kwa chogwirizira.

4. Kapangidwe ka makina

Zinthu zitatu zotsatirazi zimaganiziridwa makamaka: mphamvu ya chivomerezi yomwe iyenera kupirira; mphamvu ya mphepo yochuluka yomwe imagwira ntchito pa chomangira; mphamvu yayikulu yovomerezeka ya waya pamwamba pa chomangira.

5. Kuchotsa poizoni m'thupi

Choletsa zinc oxide chopanda mipata chili ndi mphamvu yolimbana ndi kuipitsidwa kwambiri.

Chiŵerengero cha zokwawa zomwe zatchulidwa ndi muyezo wa dziko lonse ndi: Malo oipitsidwa apakati a Gulu II: chiŵerengero cha zokwawa 20mm/kv; Malo oipitsidwa kwambiri a Gulu III: chiŵerengero cha zokwawa 25mm/kv; Malo oipitsidwa kwambiri a Gulu IV: chiŵerengero cha zokwawa 31mm/kv.

6. Kudalirika kwambiri pa ntchito

Kudalirika kwa ntchito ya nthawi yayitali kumadalira mtundu wa chinthucho komanso ngati kusankha chinthucho kuli koyenera. Ubwino wa chinthucho womwe umakhudza makamaka uli ndi zinthu zitatu izi: kumveka bwino kwa kapangidwe kake konse ka chogwirira; makhalidwe a volt-ampere ndi makhalidwe oletsa kukalamba a mbale ya valve ya zinc oxide; magwiridwe antchito otseka a chogwirira.

7. Kulekerera kwa mafupipafupi a mphamvu

Chifukwa cha zifukwa zosiyanasiyana mu dongosolo lamagetsi, monga kukhazikika kwa gawo limodzi, mphamvu yayitali komanso kukana kunyamula katundu, mphamvu yamagetsi imakwera kapena mphamvu yopitilira muyeso yokhala ndi mphamvu yayikulu imapangidwa. Chogwirizira chimatha kupirira mphamvu inayake mkati mwa nthawi inayake. Mphamvu yowonjezera mphamvu.
