摘　　要：结合直流测试及交流测试技术,开发了基于交直流特性的变压器有载分接开关测试装置。通过测试电压及电流波形,计算开关切换过程中的过渡时间、过渡电阻、三相开断不同步时间等参数,并与标准波形、设计要求比较,从而判断出有载分接开关的运行状态。In this paper,a testing device for transformer on-load tap changer based on AC and DC characteristics is developed,which combines the DC testing and AC testing method.By measuring voltage and current waveform,the transition time,transition resistance,three-phase cut-off out of synchronization time in the diverting process can be calculated.The test results can be compared with the standard waveform and the designed requirements,then,the operation condition of on-load tap changer can be evaluated.
