| Abstract: | This paper presents the characteristics of the vaccum reform of the QC83-80N flameproof magnetic force starter with reversible air contactors used in mine. The reformed switch has adopted JDB-80N electronic complex protector to protect control motor from short circuit, overload, openphase and lock for leakage, etc. The combination of new mechanical interlocking mechanism and control circuit can lock reversible vaccum contactors not only in electricity but also in mechanism, which improves the interlocking reliability of two contactors. |
