Abstract: For getting larger start thrust and meeting high reliability of high-voltage circuit breaker of breaking capacity and mechanical performance cylinder linear induction motor(C-LIM) used in breaker operating mechanism was optimized design in this paper, and particle swarm optimazation(PSO) algorithm was introduced into C-LIM design. C-LIM overall optimization with neighbourhood topology particle swarm optimization(NPSO) was still proposed in the paper, and complicated optimize problem of PSO algorithm with local optimal value were solved. Search capacity of particle was increased with NPSO algorithm. Two algorithm result indicate that start thrust is increased greatly and start current is reduced greatly, especially NPSO algorithm get remarkable result. Construction and size of C-LIM are reduced, weight of C-LIM is cut down, material of C-LIM are economized on, NPSO algorithm superiority is proved, and practicality of C-LIM mechanism is improved and perfect.
