Overview

ZN63(VS1) -12 series indoor high-voltage vacuum circuit breaker is indoor high-voltage switchgear, inokodzera matatu-phase power system ine rated voltage ye12kV uye frequency ye50Hz.Inoshandiswa sekudzivirira uye kutonga midziyo yemagetsi.Kuita kwakanakisa, kunyanya kwakakodzera nzvimbo dzinoda kugara uchivhiya panguva yakayerwa, kana kutyora-pfupi-yedunhu ikozvino kakawanda.
ZN63(VS1) -12 yakatevedzana-yakaiswa vacuum circuit breaker inotora yakagadziriswa kuisirwa uye inonyanya kushandiswa kune yakagadziriswa switch kabati.system.

Normal Kushandisa Conditions

◆ Ambient tembiricha: - 10 ℃ kusvika 40 ℃ (kuchengetera uye chekufambisa pa - 30 ℃ zvinobvumirwa).

◆ Altitude: kazhinji kwete kupfuura 1000m.(Kana zvichidikanwa kuwedzera urefu, iyo yakatemerwa insulation level ichawedzera zvinoenderana)

◆ Hunyoro hunyoro: pasi pemamiriro ezvinhu, chiyero chezuva nezuva hachipfuuri 95%, chiyero chezuva nezuva chakazara saturated steam pressure MPa, uye mwedzi wepamwedzi haisi kupfuura 1.8 × gumi.

◆ Seismic simba: kwete kupfuura 8 degrees pasi pemamiriro ezvinhu akajairika.

◆ Inogona kushandiswa chete munzvimbo dzisina moto, kuputika, kusvibiswa kwakakomba, kusvibiswa kwemakemikari uye kudengenyeka kwakakomba.
