Overview
Arrester is overvoltage protector, iyo inonyanya kushandiswa kuchengetedza midziyo yemagetsi yakasiyana-siyana (transformer, switch, capacitor, arrester, transformer, generator, motor, power cable, etc.) masisitimu akadai semagetsi system, njanji electrification system uye yekutaurirana system Dziviriro ye atmospheric overvoltage, oparesheni overvoltage uye simba frequency transient overvoltage ndiyo hwaro hwekuvharisa kurongeka kwesimba system.Chinhu chayo chikuru ndeye zinc oxide.Iyo inosunga mheni inowanzobatanidzwa pakati pegridi conductor uye tambo yepasi, uye dzimwe nguva inobatanidzwawo pedyo nemagetsi emhepo kana pakati pemakonduri.
Iyo yakakosha element (resistor) yesimbi oxide arrester (MOA) inotora iyo yepamusoro fomula yakavakirwa pazinc oxide, ine yakanakisa nonlinear (volt ampere) hunhu, kureva, pasi peyakajairika kushanda voltage, yazvino inopfuura inongova micro ampere level. .Kana over-voltage inogamuchirwa, ikozvino kupfuura inogona kusvika kuzviuru zveamperes pakarepo, saka musungwa ari mumamiriro ekuitisa uye anobudisa simba rinopfuura-voltage, nokudaro zvinobudirira kuderedza kukuvadzwa kwe-over-voltage kune simba rekufambisa uye kushandura midziyo.
Iyo yechinyakare yeSiC inosunga ine kushaikwa kwemhepo yakakwira yemhepo inoyerera nekuda kwekunonoka kwekuyerera kwemafungu emhepo, uye yakakwirira kushanda wave discharge voltage nekuda kwekupararira kukuru kwekushanda kwemafungu.Zinc oxide arrester ine mabhenefiti eakanaka emawere anopindura, hapana kunonoka kweanokwidza wave voltage, yakaderera residual voltage, hapana kubuda kubuda, nezvimwewo. Muganho wekudzivirira wemawere uye wave wave unoshanda unovandudzwa zvakanyanya.Panyaya yekubatanidza kusungirirwa, miganho yekudzivirira yemafungu anokwira, mafungu emheni uye mafungu ekushanda anogona kunge akafanana, kuitira kuti ipe dziviriro yakanakisa yemidziyo yemagetsi.
Iyo composite sheathed metal oxide arrester inotora iyo yakazara jekiseni yekuumba maitiro maviri emagumo ekurongedza, ane yakanaka yekuisa chisimbiso kuita, yakanakisa kuputika-chiratidziro kuita, kusvibiswa kwekudzivirira, hapana chikonzero chekuchenesa, inogona kuderedza kuitika kwekunaya kwemvura mumazuva ane mhute, uye iri inoshingirira mukuora kwemagetsi, kuchembera, diki mukukura, kureruka muhuremu, uye nyore kuisa nekuchengetedza.Iyo inotsiva porcelain bushing arrester.
Features
1. Saizi diki, uremu huremu, kupokana kuramba, hapana kukuvara, kuchinjika kuisirwa, kwakakodzera switchgear
2. Chimiro chakakosha, kuumbwa kwese, hapana gap remhepo, kuita kwakanaka kwekuvhara, hunyoro-uchapupu uye kuputika-uchapupu.
3. Yakakura creepage chinhambwe, yakanaka kudzoreredza mvura, yakasimba anti kusvibiswa kugona, kuita kwakagadzikana, uye kuderedzwa kushanda nekugadzirisa.
4. Zinc oxide resistor, yakasarudzika formula, diki inodonha ikozvino, inononoka kuchembera, yakanaka yekupindura maitiro, hapana inoenderera ikozvino, yakakura ikozvino simba, yakaderera residual voltage, simba rakasimba rekudzvanya overvoltage, kusvibiswa kuramba, anti-kuchembera, kusununguka kubva pakakwirira , chimiro chakareruka, hapana gap, chisimbiso chakasimba, hupenyu hurefu uye mamwe maitiro.
5. Iyo chaiyo DC reference voltage, square wave ikozvino simba uye yakakwirira ikozvino kushivirira yakakwirira kudarika mitemo yenyika
6. Pasi peyakajairika system inoshanda voltage, ichi chinosunga chinopa yakakwira yekupikisa mamiriro, uye chete microamp ikozvino inopfuura.Pasi pechiito che-over-voltage uye yakakura ikozvino, inopa kushomeka kwakadzika, nekudaro ichidzikamisa yakasara voltage kumagumo ese emusungwa.
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.
