Research on short - circuit protection of Mine Small Explosion - Proof Vacuum Magnetic Starter

At present,most of mine small explosion-proof switches adopt manual mode,which has the problems such as function deficiency,without fault deadlock and so on.After synthesizing and analyzing the current development in and out,this paper has designed a kind of intelligent mine small explosion-proof vacuum magnetic starter.The advanced single-chip computer technology and the new protection principle are adopted in this circuit.In the trial,the starter represented perfect integrated protection and faults locking function.The communication circuit is credibility and stable.The requirement is fulfilled.
