The Permanent Magnet Operating Mechanism of Double Coil Parallel Driven at a High Speed

WEI Xin-lao;WAN Run-nan;School of Electrical and Electronic Engineering,Harbin University of Science and Technology;  
Operating mechanism is the main part of breaker,and the quality of breaker will directly influence the safe operation of power system.Because of the continuous improvement requirements of switch,in order to mak this actuator faster and more powerful closing,this paper proposes a double coil parallel driven permanent magnet actuator at a high speed.This paper expounds the working principle of single and double coil parallel driven permanent magnet actuator.It uses Ansoft building model and contrasts test results.In pratice we designed and produced the single and double coil parallel driven permanent magnet actuator for experimental study.The simulation and experiment results show that double coil parallel driven permanent magnet actuator,compared with single coil parallel driven permanent magnet actuator,has a better and faster action performance.Thus,the double coil parallel driven permanent magnet actuator achieves a kind of optimization.
