ZW7-40.5 Kunze High Voltage Vacuum Circuit Breaker

Overview

ZW7-40.5 yekunze yekutengesa voltage AC vacuum circuit breaker ine zvakanakira zvekuchengetedza uye zvakavimbika kuita, kugadzirisa kuri nyore uye kutenderera kwenguva refu.Nekuda kwekushandiswa kwekuzadza zvinhu zvitsva zvinodzivirira, chimiro chese cheiyo isina-condensing transformer iri kunze kwekamuri yekudzimisa arc uye madziro emukati eporcelain sleeve anoiswa mubhokisi remashini, iro rakanakira kuiswa.Iyo zvakare inodzivirira iyo mafuta, gasi kuvuza uye toxicity matambudziko emamwe ma switch.Nekuti iyo ine simba uye static mabatirwo edunhu anotyora akavharirwa muvacuum arc yekudzimisa kamuri, uye vacuum inoshandiswa seyekudzivirira svikiro uye arc yekudzima svikiro, ine yakatevedzana mabhenefiti ayo mamwe marudzi ekuchinja haakwanise kuenderana.Saka chigadzirwa ichi chigadzirwa chakanakira kutsiva DW akawanda-oiri wedunhu breaker.Chimiro chebhokisi rekushandisa rekushandisa rechigadzirwa ichi chiri pakati pechitsiko chedunhu chiripakati chepamusoro-voltage vacuum circuit breaker.Rudzi urwu rwekutyora kwedunhu ipfupi 260mm pane rekutanga redunhu, uye rakakodzera kuiswa munzvimbo dzine nzvimbo shoma.
Ichi chigadzirwa chakakodzera 40.5kV, 50.Hz matatu-phase simba rekugovera sisitimu, seyekuremedza ikozvino, yakawandisa ikozvino uye pfupi-yedunhu ikozvino ye sub uye chiteshi.

Basa Rakakosha

◆Kushandisa vacuum arc kudzimisa.Yakasimba yekutyora simba, hupenyu hurefu hwemagetsi, uye hupenyu hwemuchina we10,000 nguva:
◆ Chimiro chakareruka, kuchengetedza-kusina, nguva refu isina kugadziriswa;
◆ Kushanda zvakanaka kwekudzivirira uye simba rakasimba rinopesana nekusvibiswa;
◆Inogona kunge yakashongedzerwa nepfuti kana yemagetsi mapurisa ekushandisa, ine yakavimbika mechanical performance uye kazhinji kushanda;hapana moto uye njodzi dzinoputika;
◆ Yakavakwa-muzvino transformer, kururamisa kwemudzidzisi kunosvika ku0.2, iyo inogona kuona kuchengetedzwa kwezvikamu zvitatu zvinopindirana;
◆A condensing controller inosungirirwa, iyo inogona kuchengetedza dunhu rakazaruka uye kushanda zvakavimbika pasi pehumwe hutsi uye hunyoro.

Shandisa Environmental Conditions

◆ Ambient air tembiricha: yepamusoro muganhu +40 ℃, yakaderera muganhu -30 ℃;
◆ Altitude: 200.0m (kana kukwirira kuchida kuwedzerwa, iyo yakarongwa yekudzivirira yezinga ichawedzerwa maererano),
◆ Kudzvinyirira kwemhepo: hapana kupfuura 700.Pa (yakaenzana nemhepo inomhanya ye34m / s),
◆Amplitude: seismic intensity B degree z
◆ Mwero wekusvibiswa: Ⅲ nhanho;
◆Maximum zuva nezuva tembiricha musiyano: hapana kupfuura 25 ℃
