Jacket Yophatikiza Yamagulu Atatu Yophatikiza Zinc Oxide Arrester

Mwachidule

Metal oxide arrester (MOA) ndi chida chofunika kwambiri chotetezera chomwe chimagwiritsidwa ntchito kuteteza kutsekemera kwa magetsi ndi zida zosinthira ku zoopsa zowonongeka.Imayankha mwachangu, mawonekedwe osalala a volt-ampere, magwiridwe antchito okhazikika, mphamvu yayikulu, mphamvu yotsalira yotsika, komanso moyo wautali., kapangidwe kosavuta ndi zina zabwino, zomwe zimagwiritsidwa ntchito kwambiri popanga magetsi, kutumiza, substation, kugawa ndi machitidwe ena.Chomangira chophatikizika cha jekete yachitsulo cha oxide chimapangidwa ndi zinthu zopangidwa ndi mphira wa silicone.Poyerekeza ndi chomangira jekete ladothi lakale, ili ndi zabwino zake zazing'ono, kulemera kwake, kapangidwe kolimba, kukana kuipitsidwa kwamphamvu, komanso kuchita bwino kosaphulika.Pamene womangayo ali pansi pamagetsi oyendetsa bwino, magetsi omwe akuyenda kudzera pa womangayo ndi microampere yokha.Pokhala ndi kuchulukirachulukira, chifukwa cha kusagwirizana kwa kukana kwa zinc oxide, zomwe zikuyenda kudzera pa womanga nthawi yomweyo zimafika masauzande a amperes, ndipo womangayo ali mumayendedwe.Tulutsani mphamvu zowonjezera mphamvu, motero kuchepetsa kuwonongeka kwa overvoltage ku magetsi opatsirana ndi zida zosinthira.

Mitundu itatu yophatikizika yokhala ndi jacket ya zinc oxide arrester ndi mtundu watsopano wa chipangizo choteteza chomwe chimagwiritsidwa ntchito kuteteza kutsekemera kwa zida zamagetsi kungozi zowopsa.Imachepetsa kuwonjezereka kwa gawo-to-ground overvoltage pamene imachepetsa mphamvu ya gawo-to-phase overvoltage.Amagwiritsidwa ntchito kwambiri kuteteza ma switch a vacuum, makina amagetsi ozungulira, ma capacitor olipira ofanana, magetsi, malo ocheperako, ndi zina zambiri. Zomangamanga zophatikizika izi zakhala zikuyenda kwazaka zopitilira khumi, ndipo zatsimikiziridwa kuti ndi njira yotheka komanso yothandiza kuchepetsa kuchulukirachulukira. pakati pa magawo.Chomangira opaleshoni chimagwiritsa ntchito mphamvu zazikulu za zinc oxide resistors monga gawo lalikulu, lomwe lili ndi makhalidwe abwino a volt-ampere komanso luso lotha kuyamwa mopitirira muyeso, ndipo limapereka chitetezo chodalirika pazida zotetezedwa.Zakhala zikugwiritsidwa ntchito kwambiri mu machitidwe a mphamvu.
