摘　　要：针对当前实验室使用气动试验装置对小型断路器进行机械电气寿命试验时速度不可控,易损伤手柄,操作路径简单,不足以执行所有产品手柄的合闸等问题,设计了一种小型断路器合分闸操作试验系统。系统通过三轴运动控制,以平稳可控的运动速度和弧形运动轨迹实现产品手柄的合闸操作,产品适用范围更广;通过在末端执行器上搭载力传感器,实现在执行试品手柄合闸时的合闸力实时监测;通过搭载机器视觉系统实现试品试验操作位置的智能获取。试验结果表明,所提出的试验系统能在不同合闸操作中监测到具有不同特征的力变化情况,且试验系统的弧形合闸速度能满足国标要求。In order to address the shortcomings of existing pneumatic testing devices used to execute mechanical and electrical life tests of MCB in the laboratory,such as uncontrollable speed and easily making handles damaged,as well as too simple operation path which is not sufficient to perform all MCBs' handle closing,a test system for the closing and opening operation of MCB is designed.The system achieves the closing operation of the product handle with a stable and controllable speed and curved motion trajectory through three-axis motion control.The product has wider applicability.By installing a force sensor on the end effector,the real-time monitoring of the closing force during the closing and opening of the test handle can be achieved.By carrying machine vision,the intelligent acquisition of operation position of the test samples can be achieved.The experimental results show that the proposed test system can monitor the changing force with different characteristics in the different closing operations,and the arc-shaped closing speed of the test system can meet the requirements of national standards.
