A thyristor circuit and the analysis of mechanical characters, principle and connection of brake parts of its power lines are presented in this paper. The trigger circuit of thyristor was improved.
International standard five-bolt structure: With the prying-resistant trigger bolt and indoor locking dead bolt for security and the mechanical key for emergency access;
