背景技术Background technique

目前，许多大型核电站每年都要进行一次换料大修，而在大修中，每次都要对RIC系统的选择器进行测试，由于现场测试时没有专用工具，并且选择器驱动电机的启动电流这项指标至关重要，也是现场人员最为关心的，启动电流过大，说明电机的阻力矩过大，就需对设备进行进一步的检查，而现场人员对此项技术指标的检查一直是通过串接万用表来进行的，万用表阻容大，不易捕捉到启动电流的峰值，往往无法正确的做出判断。At present, many large nuclear power plants have to undergo a refueling overhaul every year, and in the overhaul, the selector of the RIC system must be tested every time, because there is no special tool for on-site testing, and the starting current of the selector drive motor The index is very important, and it is also the most concerned by the on-site personnel. If the starting current is too large, it means that the resistance torque of the motor is too large, and further inspection of the equipment is required. The inspection of this technical index by the on-site personnel has always been through a multimeter connected in series. The multimeter has a large resistance and capacitance, and it is difficult to capture the peak value of the starting current, so it is often impossible to make a correct judgment.
