YH5WZ 35KV zinc oxide arrester ye high voltage power station

Tsanangudzo Pfupi

Iyo yepakati element (resistor sheet) yesimbi oxide arrester inotora fomula yepamusoro yakavakirwa pazinc oxide, ine yakanakisa nonlinear (volt-ampere) maitiro, kureva, pasi peyakajairika yekushanda voltage, ikozvino kupfuura inongova microampere level., Kana ichiiswa kune overvoltage, ikozvino inopfuura inosvika zviuru zveamperes pakarepo, zvichiita kuti musungwa ari mumamiriro ekuitisa uye kusunungura overvoltage simba, nokudaro zvinobudirira kuderedza kukanganisa kwe overvoltage kune simba.

Product Description

Surge arrester imhando ye overvoltage dziviriro, iyo inonyanya kushandiswa kuchengetedza zvakasiyana siyana zvemagetsi (transformers, switch, capacitors, wave arresters, transformer, jenareta, motors, tambo dzemagetsi, nezvimwewo) mumasisitimu emagetsi, masisitimu emagetsi enjanji, uye kutaurirana. systems.) inodzivirirwa kubva kumhepo yakawandisa, inoshanda yakawandisa uye simba frequency transient overvoltage, nezvimwewo, uye ndiyo hwaro hwekusungirirana kwesimba remagetsi masisitimu.
Iyo yepakati element (resistor sheet) yesimbi oxide arrester inotora fomula yepamusoro yakavakirwa pazinc oxide, ine yakanakisa nonlinear (volt-ampere) maitiro, kureva, pasi peyakajairika yekushanda voltage, ikozvino kupfuura inongova microampere level., Kana ichiiswa kune overvoltage, iyo inodarika ikozvino inosvika zviuru zveamperes pakarepo, ichiita musungwa mune inoitisa mamiriro uye kusunungura overvoltage simba, nokudaro zvinobudirira kudzikamisa kukuvadzwa kwe overvoltage kune simba kutapurirana uye shanduko midziyo.
Iyo yechinyakare SiC arrester ine zvakaipira zveakakwira steep wave discharge voltage zvichikonzerwa nekunonoka kubuda kwemafungu, uye yakakwirira yekushandisa wave discharge voltage nekuda kwekupararira kweave wave discharge.Iyo zinc oxide inosunga ine mabhenefiti eakanaka emawere mafungu ekupindura maitiro, hapana kunonoka kune inokwira wave voltage, yakaderera inoshanda yasara voltage, uye hapana kubuda kubuda.Iyo yekudzivirira muganho wemafungu emawere uye masaisai ekushanda inovandudzwa zvakanyanya, uye maererano nekubatanidza kusungirirwa, miganho yekudzivirira yemasaisai akadzika, masaisai emheni uye masaisai anoshanda anogona kunge akafanana, nekudaro achipa dziviriro yakanakisa yemidziyo yemagetsi.
Iyo composite bhachi simbi oxide arrester inotora iyo yakazara jekiseni molding uye maviri-ekupedzisira encapsulation process, ine yakanaka yekuisa chisimbiso, yakanakisa kuputika-proof kuita, kusvibiswa kwekudzivirira, kusacheneswa, uye kunogona kuderedza kuitika kwekunyorova kwemamiriro ekunze, yemagetsi corrosion resistance. , anti-kuchembera, saizi diki, uremu huremu, nyore kuisa nekuchengetedza.Icho chinotsiva chigadzirwa che porcelain sleeve arrester.

Tsanangudzo Yemuenzaniso

Chigadzirwa technical parameters uye kusarudzwa

Chigadzirwa Chimiro maficha uye chiyero chekushandiswa

1. Saizi diki, huremu huremu, kudhumhana kuramba, hapana kukuvadzwa kwekufambisa, kuchinjika kuisirwa, kwakakodzera kushandiswa mukuchinja makabati.
2. Chimiro chakakosha, kuumbwa kwakabatana, hapana gap remhepo, kuita kwakanaka kwekuvhara, hunyoro-uchapupu uye kuputika-uchapupu.
3. Yakakura creepage kureba, yakanaka repellency yemvura, yakasimba tsvina inopikisa, kuita kwakagadzikana uye kuderedzwa kushanda nekugadzirisa.
4. Zinc oxide resistor ine yakasarudzika formula, diki inodonha ikozvino, inononoka kuchembera nekukurumidza uye hupenyu hurefu hwebasa
5. Iyo chaiyo DC inotaridzirwa voltage, square wave ikozvino simba uye yakakwirira ikozvino kushivirira yakakwirira kudarika yenyika yose
Kuwanda kwesimba: 48Hz ~ 60Hz
-Ambient tembiricha:-40°C~+40°C
-Maximum mhepo yekumhanya: isingapfuure 35m / s
-Altitude: haipfuure 2000m
-Kudengenyeka kwepasi: kusapfuudza 8 madhigirii
-Ice ukobvu: haipfuure 10 metres.
-Nguva refu yekushandisa voltage haipfuure iyo yakanyanya coutinuous yekushandisa voltage.

Zvigadzirwa Zvinotsanangurwa uye Maitiro Ekugadzira

Zviyero zvekushandiswa kwechigadzirwa uye zviziviso zvevashandisi

Muyero wekugadzira wechigadzirwa ndeye GB11032-2000 (eqv IEC60099-4: 1991) "AC No-gap Metal Oxide Surge Arrester", JB/8952-2005 "Composite Jacket No-gap Metal Oxide Surge Arrester ye AC System"
1. Musungwa anofanira kuchengetwa muimba yakachena uye yakaoma isati yaiswa uye kushandiswa.Haifanirwe kusvibiswa nemagasi anoparadza kana zvinwiwa.
2. Musungwa asati aiswa mukushanda, chirongwa chekudzivirira chinofanira kuitwa.Mushure mekushandiswa, inofanirawo kugara ichisungwa (10KV uye pasi pemusungwa kamwe chete pamakore mashanu, 35KV uye pamusoro pemusungwa kamwe chete pamakore maviri)
Ita iyo inotevera bvunzo uye enzanisa neiyo data usati washanda uchitarisa kune yakanamatira tafura:
a.Edza kudzivirira kwekudzivirira kwemusungwa
b.Edza iyo DC 1mA voltage yeanosunga
c.Eresa kudonha kwazvino kwe0.75 nguva DC 1mA
