Arrester ndi overvoltage mtetezi, amene makamaka ntchito kuteteza zipangizo zosiyanasiyana magetsi (thiransifoma, lophimba, capacitor, womanga, thiransifoma, jenereta, galimoto, mphamvu chingwe, etc.) machitidwe monga dongosolo mphamvu, dongosolo njanji magetsi ndi dongosolo kulankhulana Chitetezo cha mumlengalenga overvoltage, ntchito overvoltage ndi mphamvu pafupipafupi chosakhalitsa overvoltage ndi maziko a kutchinjiriza mgwirizano wa mphamvu dongosolo.Chinthu chake chachikulu ndi zinc oxide.Chomangira mphezi nthawi zambiri chimalumikizidwa pakati pa woyendetsa gridi ndi waya pansi, ndipo nthawi zina chimalumikizidwanso pafupi ndi mafunde amagetsi kapena pakati pa owongolera.
The core element (resistor) of metal oxide arrester (MOA) imatenga njira yotsogola yotengera zinc oxide, yomwe ili ndi mawonekedwe abwino kwambiri a nonlinear (volt ampere), ndiye kuti, pansi pamagetsi ogwirira ntchito, mphamvu yomwe ikudutsa pano ndi yaying'ono ya ampere. .Pamene over-voltage ilandiridwa, zomwe zikudutsa panopa zimatha kufika zikwi za amperes nthawi yomweyo, kotero womangidwayo ali m'boma la conduction ndipo amatulutsa mphamvu yamagetsi, motero kuchepetsa kuwonongeka kwa mphamvu yamagetsi kumagetsi opangira magetsi ndi zida zosinthira.
Chomangira chachikhalidwe cha SiC chimakhala ndi vuto lamagetsi othamanga kwambiri chifukwa cha kuchedwa kwa mafunde amphamvu, komanso mphamvu yayikulu yotulutsa mafunde chifukwa cha kubalalitsidwa kwakukulu kwa mafunde akugwira ntchito.Zinc oxide arrester ili ndi ubwino wa kuyankha kwa mafunde otsetsereka, osachedwetsa voteji yotsetsereka, magetsi otsika otsalira, osabalalika, ndi zina zotero. Mphepete mwa chitetezo cha mafunde otsetsereka ndi mafunde ogwirira ntchito ndi abwino kwambiri.Pankhani yolumikizana ndi kusungunula, malire achitetezo a mafunde otsetsereka, mafunde amphezi ndi mafunde ogwirira ntchito amatha kukhala ofanana, kuti apereke chitetezo chabwino kwambiri cha zida zamagetsi.
Chomangira chachitsulo chophatikizira chachitsulo cha oxide chimatengera njira yonse yopangira jekeseni pamapaketi awiri, omwe amakhala ndi ntchito yabwino yosindikiza, ntchito yabwino kwambiri yosaphulika, kukana kuyipitsa, osafunikira kuyeretsa, imatha kuchepetsa kuthwanima kwamadzi m'masiku a chifunga, ndipo kugonjetsedwa ndi dzimbiri zamagetsi, kukalamba, kukula kochepa, kulemera kwake, komanso kosavuta kukhazikitsa ndi kusamalira.Ndilo m'malo mwa porcelain bushing arrester.
Mawonekedwe
1. Kukula kwakung'ono, kulemera kopepuka, kukana kugundana, kusawonongeka, kusinthika kosinthika, koyenera switchgear
2. Kapangidwe kapadera, kuumba konse, kulibe kusiyana kwa mpweya, ntchito yabwino yosindikiza, chinyezi komanso kuphulika
3. Mtunda waukulu wa creepage, kuthamangitsa madzi bwino, mphamvu zotsutsana ndi kuipitsidwa, kugwira ntchito mokhazikika, ndi kuchepa kwa ntchito ndi kukonza.
4. Zinc oxide resistor, mawonekedwe apadera, kutayikira pang'ono, kuthamanga kwapang'onopang'ono, kukalamba pang'onopang'ono, kuyankha bwino, kusapitilira pakali pano, mphamvu yayikulu yapano, kutsika kotsalira kwamagetsi, kutha kuletsa kuchulukira kwamagetsi, kukana kuipitsidwa, kukana kukalamba, kusakhala ndi zopinga zokwera. , dongosolo losavuta, palibe kusiyana, kusindikiza kolimba, moyo wautali ndi makhalidwe ena.
5. Mphamvu zenizeni za DC, mphamvu zamakono zamakono komanso kulolerana kwamakono ndizokwera kwambiri kuposa miyezo yapadziko lonse
6. Pansi pa mphamvu yamagetsi yogwira ntchito, chomangirira ichi chimapereka mphamvu yotsutsa, ndipo ma microamp okha amadutsa.Pansi pa mphamvu yamagetsi ndi mphamvu yaikulu, imasonyeza kukana kochepa, motero kuchepetsa mphamvu yotsalira pamapeto onse a womanga.
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.
