Abstract: In allusion to the mechanical reliability problem of the two types of automatic transfer switching equipment (ATSE) level CB and level PC, this paper carried out analysis from the angle of mechanical design. According to the mechanical structure schematic diagram of various ATSE, this paper expound the main causes of mechanical failure and put forward the improved measures. The practical application show that after improvement, the mechanical reliability of ATSE increases and the products failure rate reduces.
Key words: automatic transfer switching equipment; CB level; PC level; mechanical reliability
