Abstract:

The eddy repulsion mechanism with double coil was used to replace the traditional electromagnetic mechanism to improve the breaking speed of the contact,decrease the arc erosion,and reduce the contact bounce during closing at the same time.The optimal design of eddy current repulsion mechanism with double coil will provide the basis for the design of a new kind of HVDC relay.The influence of eddy current repulsion mechanism parameters on dynamic characteristics was analyzed by analytical method.On this basis,Ansoft Maxwell software was used to establish two-dimensional mathematical model of eddy current repulsion mechanism,combining with MATLAB software for the joint simulation.The cuckoo algorithm was introduced into the optimal design to obtain the optimal parameters of eddy current repulsion mechanism,and the optimized eddy current repulsion mechanism has better dynamic performance.

Key words: eddy current repulsion mechanism with double coil, HVDC relay, joint simulation, cuckoo algorithm
