Overview
Surge arrester imhando ye overvoltage dziviriro, iyo inonyanya kushandiswa kuchengetedza zvakasiyana siyana zvemagetsi (transformer, switch, capacitors, arresters, transformers, jenareta, motors, tambo dzemagetsi, nezvimwewo) mumasisitimu emagetsi, njanji magetsi masisitimu, uye masisitimu ekutaurirana. ..) Kudzivirirwa kweatmospheric overvoltage, kushanda overvoltage uye simba frequency transient overvoltage ndiyo hwaro hwesimba system insulation coordination.
Operating musimboti disconnector
Kana musungwa achishanda zvakajairika, iyo disconnector haizoiti, ichiratidza yakaderera impedance, iyo isingazokanganisa maitiro ekudzivirira eanosunga.Iyo inosunga ine disconnector yakachengeteka, kuchengetedza mahara, yakanakira uye yakavimbika.Kune marudzi maviri emheni anosunga zvisuni: hot kuputika mhando uye inopisa melt type.Iyo inopisa melt type disconnector haigone kukurumidza kubviswa kana ikatadza nekuda kwekukanganisa kwayo kwemaitiro, saka iyo inopisa kuputika mhando disconnector inowanzoshandiswa nhasi.Iyo yekutanga kupisa kwekuputika disconnector yakashandiswa neGE sesilicon carbide valve arrester.Nheyo yayo yekushanda ndeyekubatanidza capacitor mukuwirirana pane gap rekuburitsa, uye iyo inopisa inoputika chubhu inoiswa mune yakaderera electrode yekubuda gap.Kana musungwa achishanda zvakajairika, kudonhedza kwemagetsi kwemheni uye kushanda kwazvino pa capacitor hakuna kukwana kuita gap rekuburitsa, uye disconnector haiite.Kana musungwa akuvadzwa nekuda kwekukanganisa, kudonha kwevoltage yemagetsi frequency kukanganisa ikozvino pane capacitor inoita yekuburitsa gap kuputsa uye kuburitsa, uye iyo arc inoramba ichipisa iyo inopisa kuputika chubhu kusvika iyo disconnector ichiita.Nekudaro, kune kwaakarerekera point yakananga pasi masisitimu pamusoro pe20A, iyi mhando yekudimburira haigone kuve nechokwadi chekuti inoshanda pasi pediki simba frequency kukanganisa ikozvino.Iyo nyowani yekupisa inoputika yekuburitsa mudziyo inoshandisa varistor (silicon carbide kana zinc oxide resistor) yakabatana padivi pegeji rekuburitsa, uye tembiricha inoputika inoiswa muzasi electrode.Pasi pesimba diki frequency kukanganisa ikozvino, iyo varistor inopisa, inobvisa iyo inopisa kuputika chubhu, uye mudziyo wekuburitsa unoshanda.
Features
1. Yakareruka muhuremu, idiki muhuwandu, inopesana nekupesana, inodonha chiratidzo uye inochinjika mukuisa, uye inokodzera switchgear, ring network cabinet uye mamwe switchgear.
2. Yakaumbwa yakabatanidzwa, isina gap remhepo, ine chisimbiso chakanaka chekuita, unyoro-uchapupu uye kuputika-uchapupu, uye chimiro chakakosha.
3. Yakakura creepage chinhambwe, yakanaka kudzoreredza mvura, yakasimba anti kusvibiswa kugona, kuita kwakagadzikana, uye kuderedzwa kushanda nekugadzirisa.
4. Yakasarudzika fomula, zinc oxide kuramba, yakaderera leakage ikozvino, inononoka kuchembera kumhanya uye hupenyu hurefu hwebasa.
5. Iyo chaiyo DC referensi voltage, sikweya wave ikozvino kugona uye yakakwirira ikozvino kushivirira yakakwira kupfuura miyero yenyika uye yepasirese mwero.
Kuwanda kwesimba: 48Hz ~ 60Hz
Mamiriro Ekushandisa
- Ambient tembiricha: -40°C~+40°C
-Maximum mhepo kumhanya: hapana kupfuura 35m / s
-Kureba: kusvika ku2000 metres
-Kudengenyeka kwepasi: kusapfuura 8 madhigirii
- Ice ukobvu: kwete kupfuura 10 metres.
- Iyo yenguva refu yakashandiswa voltage haipfuure iyo yakanyanya kuenderera kushanda voltage
