Abstract
A flameproof three-power vacuum electromagnetic starter for a coal mine fan comprises a housing. The internal of the housing is divided into three equal accommodating chambers via isolation plates. A group of single-chip microcomputers and current transformers, a fuse, a vacuum AC contactor and an AC contactor component are disposed in each accommodating chamber. Conductive binding posts are disposed at corresponding positions of two sides of each isolation plate. Big horn-shaped mouths, middle horn-shaped mouths and small horn-shaped mouths are disposed on the housing where the accommodating chambers are located; and the big horn-shaped mouths are used to lead power lines in, the middle horn-shaped mouths are used to lead the power lines out, and the small horn-shaped mouths are used to monitor leading-in of the lines and leading-out of signal control lines. Multiple paths of power supplies are integrated in one power vacuum electromagnetic starter chamber, so each group of internal components, leading-in of the power lines and leading-out of the power lines meet explosion-proof requirements, and reliability reduction caused by decentralized arrangement is prevented. Corresponding power line controllers can share states of the lines, and can coordinate switch-on time and switch-off time of the power supplies; and the coal mine fan is guaranteed to run reliably.
