Mwachidule
Zinc oxide arrester ndi chomangira chokhala ndi chitetezo chabwino.Makhalidwe abwino osagwirizana ndi volt ampere a zinc oxide amapangitsa kuti madzi akuyenda kudzera pa chomangirira akhale ochepa kwambiri (micro ampere kapena milliampere level) pansi pa voteji wamba;Pamene mphamvu yowonjezera ikugwira ntchito, kukana kumatsika kwambiri, ndipo mphamvu yowonjezera-voltage imatulutsidwa kuti ikwaniritse chitetezo.Kusiyanitsa pakati pa womanga uyu ndi womangidwa mwachikhalidwe ndikuti alibe mpata wotulutsa ndipo amapezerapo mwayi pazikhalidwe zopanda zinc oxide kuti atulutse pakali pano ndikuchotsa.
Makhalidwe asanu ndi awiri a zinc oxide arrester
Mphamvu yoyenda
Izi makamaka zimaonekera mu mphamvu yomanga mphezi kuyamwa zosiyanasiyana mphezi overvoltage, mphamvu pafupipafupi chosakhalitsa overvoltage ndi kusintha overvoltage.
Makhalidwe achitetezo
Zinc oxide arrester ndi chinthu chamagetsi chomwe chimagwiritsidwa ntchito kuteteza zipangizo zosiyanasiyana zamagetsi mumagetsi kuti zisawonongeke zowonongeka, ndi chitetezo chabwino.Chifukwa cha mawonekedwe abwino kwambiri osakhala amtundu wa volt ampere a kagawo kakang'ono ka zinc oxide valve, ma microamp mazana angapo apano amatha kudutsa pansi pa voteji yogwira ntchito bwino, yomwe ndi yabwino kupanga mawonekedwe opanda malire, kupangitsa kuti ikhale ndi mawonekedwe achitetezo abwino. , kulemera kochepa ndi kukula kochepa.Pamene overvoltage intrudes, panopa akuyenda mu mbale valavu amakula mofulumira, pa nthawi yomweyo, matalikidwe a overvoltage ndi ochepa, ndipo overvoltage mphamvu amamasulidwa.Pambuyo pake, mbale ya valavu ya zinc oxide imabwerera kumalo okana kwambiri, zomwe zimapangitsa kuti magetsi azigwira ntchito bwino.
Kusindikiza ntchito
Jekete yapamwamba yophatikizika yokhala ndi ukalamba wabwino komanso kulimba kwa mpweya imagwiritsidwa ntchito pazinthu zomangira.Njira monga kuwongolera kuchuluka kwa mphete yosindikiza ndi kuwonjezera sealant zimatengedwa.Jekete ya Ceramic imagwiritsidwa ntchito ngati zosindikizira kuti zitsimikizire kusindikiza kodalirika komanso kukhazikika kwa womanga.
Zimango katundu
Zinthu zitatu zotsatirazi zikuganiziridwa makamaka: mphamvu ya chivomezi;Kuthamanga kwakukulu kwa mphepo kumachita pa womanga;Pamwamba pa womangidwayo amakhala ndi zovuta zovomerezeka zovomerezeka za kondakitala.
Kuchita kwa decontamination
Chomangira cha zinc oxide chopanda malire chimakhala ndi kukana kuyipitsa kwakukulu.
Mtunda weniweni wa creepage wotchulidwa muyeso wa dziko lonse ndi: Gulu la II, malo oipitsidwa ndi apakati: mtunda wa creepage weniweni ndi 20mm/kv;Gawo lachitatu loipitsidwa kwambiri: mtunda wa creepage 25mm/kv;Gawo la IV loipitsidwa kwambiri: mtunda wa creepage ndi 31mm/kv.
Mkulu ntchito kudalirika
Kudalirika kwa ntchito ya nthawi yayitali kumadalira mtundu wa mankhwala ndi kulingalira kwa kusankha kwa mankhwala.Ubwino wa mankhwala ake umakhudzidwa makamaka ndi zinthu zitatu zotsatirazi: kulingalira kwa dongosolo lonse la womangidwa;Makhalidwe a Volt ampere ndi kukana kukalamba kwa mbale ya zinc oxide valve;Kusindikiza ntchito kwa womanga.
Mphamvu pafupipafupi kulolerana
Chifukwa cha zifukwa zosiyanasiyana mu dongosolo mphamvu, monga gawo limodzi grounding, yaitali mzere capacitance zotsatira ndi kukanidwa katundu, mphamvu pafupipafupi voteji adzauka kapena kusakhalitsa pa-voltage ndi mkulu matalikidwe zidzachitika.Womangayo amatha kupirira kukwera kwamphamvu kwanthawi yayitali mkati mwa nthawi inayake.
Kagwiritsidwe Ntchito
- Kutentha kozungulira: -40°C~+40°C
- Kuthamanga kwa mphepo: osapitirira 35m / s
- Kutalika: mpaka 2000 metres
- Kuchuluka kwa chivomerezi: osapitilira 8 madigiri
- Makulidwe a ayezi: osapitilira 10 metres.
- Magetsi ogwiritsidwa ntchito kwa nthawi yayitali sapitilira mphamvu yopitilira ntchito.
