ZW20-12 Outdoor High Voltage Vacuum Circuit Breaker

Overview

ZW20-12 yekunze high-voltage vacuum circuit breaker ndeyekunze yakakwira-voltage switchgear ine rated voltage ye12KV uye matatu-phase AC 50Hz.Inonyanya kushandiswa kubvisa uye kuvhara mutoro wezvino, kuwedzeredza ikozvino uye pfupi-circuit ikozvino yemagetsi system.Yakakodzera kuchengetedzwa uye kutonga kwezviteshi, maindasitiri nemabhizinesi emigodhi, uye madhorobha nemaruwa ekugovera network, kunyanya kune nzvimbo dzinogara dzichishanda uye otomatiki kugovera network yedomain network.Ichi chigadzirwa chinofananidzwa nemutongi kuti asangane nezvinodiwa zvekugovera otomatiki system uye kupedzisa yechinyakare recloser basa zvakavimbika uye zvinobudirira.Iyo yakakura bhokisi-mhando yekuisa chisimbiso chimiro inogamuchirwa, uye yemukati yakazadzwa neSF6 gasi.Iyo ine yakanaka yekuisa chisimbiso kuita uye haina kukanganiswa nenyika yekunze.Ichi chigadzirwa chemahara chekuchengetedza.Iyo chitubu inoshanda sisitimu inotora yakananga-drive chain main drive uye akawanda-stage tripping system, ine yakakwirira kushanda kuvimbika.

Features

◆ Inotora vacuum arc kudzimisa uye SF6 gas insulation, iyo ine zvakanaka kuputsa kushanda;
◆ Oiri-isina, yakavharwa zvakakwana, bhokisi rakajairika, kuputika-uchapupu, unyoro-uchapupu, uye condensation-uchapupu dhizaini yekugadzira, nekugara kwenguva refu-isina;
◆ Miniaturized electric spring operating mechanism inoita kuti ive yakaderera simba rekushanda, kuvimbika kwepamusoro uye kureruka;
◆ Chigadziro chekugadzirisa chinonzwisisika, kushandiswa kwemagetsi uye kushandiswa kwemaoko kunoshanduka, uye chigaro kana kusungirirwa kwekurembera kunogona kusarudzwa nyore nyore;
◆ Nekutsigira akangwara feeder terminals, kushanda kure kunogona kuitika kuti kuzadzisa zvinodiwa zvekugovera otomatiki;

Environmental Conditions

1. Ambient tembiricha yemhepo: yepamusoro muganhu 60 °C, yakaderera muganho -30 °C;
2. Altitude: ≤ 3000m (kana kukwirira kunowedzera, chiyero chekudzivirira chekudzivirira chichawedzera maererano);
3. Amplitude: The seismic intensity haipfuure 8 madhigirii;
4. Ivhareji yemazuva ose humidity humidity yemhepo haisi kupfuura 95%, uye mwedzi wepamwedzi haisi kupfuura 90%;
5. Hapana moto, njodzi yekuputika, kusvibiswa kwakakomba, kuora kwemakemikari uye kudengenyeka kwechisimba.
