摘要
针对低压系统网络结构复杂度与用户负荷容量的持续增加,对保护与控制电器操动机构的设计提出更高要求的问题,提出一种基于粒子群多参数综合优化算法的电器快速动作机构优化设计方案.采用双线圈涡流斥力机构代替现有低压交流接触器的电磁操动机构,实现低压开关电器的快速可靠分/合闸动作,使低压集成电器的控制与保护一体化.在双线圈涡流斥力盘结构参数匹配设置的基础上,利用粒子群个体与群体的迭代追踪能力,对分合闸线圈匝数、斥力盘厚度与斥力盘间径进行多参数综合寻优,以获得机构最优参数匹配.仿真测试表明,该优化设计实现了快速动作机构10 mm的分/合闸行程,且其分闸时间为1.63 ms,平均分闸速度为6.13 m·s^(-1),合闸时间为2 ms,平均合闸速度为5 m·s^(-1),其快速操动机构具有较好的动作特性.
In view of the continuous increase of low-voltage system network structure complexity and user load capacity,higher requirements are put forward for the design of protection and control electrical operating mechanism,and an optimized design of electrical rapid-action mechanism based on particle swarm multi-parameter comprehensive optimization algorithm is proposed.The double-coil eddy current repulsive force mechanism is used to replace the electromagnetic operating mechanism of the existing low-voltage AC contactor to realize the fast and reliable opening/closing action of the low-voltage switchgear,and integrate the control and protection of the low-voltage integrated electric appliance.Based on the matching setting of the structural parameters of the double-coil eddy current repulsion disc,the iterative tracking ability of the individual and group of the particle swarm is used to comprehensively optimize the multi-parameters of the opening and closing coil turns,the thickness of the repulsion disc and the diameter of the repulsion disc.Obtain the optimal parameter matching of the organization.The simulation test shows that the optimized design realizes that under the 10 mm stroke of the fast-acting mechanism,and the opening time is 1.63 ms,the average opening speed is 6.13 m·s^(-1),the closing time is 2 ms,and the average closing speed is 5 m·s^(-1).Its fast operating mechanism has good action characteristics.
