Iyo yakatemerwa voltage yevacuum interrupter yeyakaderera-voltage circuit breaker ndeye ≤ 1500 V, iyo inonyanya kushandiswa munzvimbo dzakakosha dzekushandisa zvine zvinodiwa zvakasimba, zvakadai se: Mukuparadzirwa kwemagetsi emhepo uye kugadzirwa kwesimba rezuva, izvo zvinoda kushanda kakawanda uye basa rakareba kwazvo. life;Muminda yemakemikari nemigodhi, inodiwa kuve nekuchengetedza uye kuputika-uchapupu mabasa;Mumunda wezvikepe zvechikepe, zvinodikanwa kuve nekugona kwekupwanya kukanganisa ikozvino kwenguva dzakawanda.Iyo mhepo switch inowanzoshandiswa muminda iyi haigone kuzadzisa zvinodiwa, uye yakaderera-voltage vacuum circuit breaker ndiyo yakanakisa sarudzo.
