Overview
Zinc oxide arrester inosunga ine yakanaka kuchengetedza kuita.Iyo yakanaka nonlinear volt ampere maitiro e zinc oxide inoita kuti ikozvino kuyerera kuburikidza nemusungwa diki kwazvo (micro ampere kana milliampere level) pasi penguva dzose yekushanda voltage;Kana over-voltage ichiita, kushorwa kunodonha zvakanyanya, uye iyo-over-voltage simba inoburitswa kuti iwane kudzivirira.Musiyano uripo pakati pemusungwa uyu uye wemusungwa wechinyakare ndewekuti haana gap rekubuda uye anotora mukana weasina mutsara maitiro e zinc oxide kuburitsa ikozvino uye kudimbura.
Zvinomwe maitiro e zinc oxide arrester
Kuyerera simba
Izvi zvinonyanya kuratidzwa mukugona kweanosunga mheni kutora kwakasiyana mheni overvoltage, simba frequency transient overvoltage uye switching overvoltage.
Dziviriro maitiro
Zinc oxide arrester chigadzirwa chemagetsi chinoshandiswa kuchengetedza zvakasiyana-siyana zvemagetsi mumagetsi emagetsi kubva pakukuvadzwa kwepamusoro, nekuita kwakanaka kwekudzivirira.Nekuda kweakanakisa asiri-mutsara volt ampere maitiro e zinc oxide valve slice, mazana mashoma mamicroamps emazuva ano anogona kupfuura nepasi peyakajairwa kushanda voltage, iyo iri nyore kugadzira isina gap chimiro, ichiita kuti ive nehunhu hwekudzivirira kwakanaka kuita. , uremu huremu uye hukuru hudiki.Kana overvoltage inopinda, ikozvino inoyerera kuburikidza neplate yevhavha inowedzera nokukurumidza, panguva imwe chete, amplitude ye overvoltage inogumira, uye simba rinoputika rinosunungurwa.Mushure meizvozvo, iyo zinc oxide valve plate inodzokera kune yakakwirira yekupikisa mamiriro, zvichiita kuti simba remagetsi rishande zvakajairika.
Kuita chisimbiso
High quality composite bhachi ine basa rakanaka rekuchembera uye kusimba kwemhepo kunoshandiswa kune zvekusunga zvinhu.Matanho akadai sekudzora kuwanda kwekumanikidza kwemhete yekuisa chisimbiso uye kuwedzera sealant inogamuchirwa.Ceramic bhachi inoshandiswa sechisimbiso zvinhu kuti ive nechokwadi chekuisa chisimbiso uye yakagadzikana kuita kweanosunga.
Mechanical properties
Zvinhu zvitatu zvinotevera zvinonyanya kufungwa nezvazvo: simba rekudengenyeka kwenyika;Mhepo yakanyanya kudzvinyirira inobata pane anosunga;Musoro wemusungwa unotakura hukuru hunobvumirwa tension ye conductor.
Decontamination performance
Iyo isina gap zinc oxide arrester ine yakanyanya kusvibiswa kuramba.
Iyo chaiyo creepage kureba inotsanangurwa muyero yenyika ndeiyi: Giredhi II, yepakati kusvibiswa nzvimbo: iyo chaiyo creepage kureba ndeye 20mm/kv;Giredhi III nzvimbo yakasvibiswa zvakanyanya: creepage kureba 25mm/kv;Giredhi IV nzvimbo yakasvibiswa zvakanyanya: yakananga creepage kureba ndeye 31mm/kv.
High kushanda kuvimbika
Kuvimbika kwekushanda kwenguva refu kunoenderana nehutano hwezvigadzirwa uye kunzwisisika kwekusarudzwa kwechigadzirwa.Unhu hwezvigadzirwa zvayo zvinonyanya kukanganiswa nezvikamu zvitatu zvinotevera: kunzwisisika kwechimiro chese chemusungwa;Volt ampere maitiro uye kuchembera kuramba kwe zinc oxide valve plate;Kuvhara kushanda kwemusungwa.
Simba frequency kushivirira
Nekuda kwezvikonzero zvakasiyana-siyana musimba remagetsi, senge single-phase grounding, refu mutsara capacitance mhedzisiro uye kurambwa kwemutoro, iyo magetsi frequency voltage inosimuka kana iyo inopfupika pamusoro-voltage ine yakakwirira amplitude ichaitika.Iyo inosunga inokwanisa kumira kune imwe simba frequency voltage kusimuka mukati meimwe nguva yenguva.
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.
