摘　　要：本文对多匝重叠小回线装置不同的线圈参数和发射机参数进行了同点关断时间的实验,对比分析了同点同参数的关断时间随时间的变化规律、发射机数据采集时参数设置对关断时间的影响,以及不同线圈匝数和发射磁矩对关断时间的影响。结果表明,同一装置及参数的关断时间受线圈电阻影响较大;发射机叠加次数的设置和时间序列的选择对关断时间基本无影响;线圈匝数与其关断时间呈正比线性关系;线圈的发射磁矩与其关断时间在线圈匝数不变的情况下呈正比线性关系。This paper experiments on the turn-off time of different winding parameters and transmitter parameters of multi-turn small coincident loop. The paper compares and analyzes the influence of time and parameter settings of transmitter data acquisition, as well as the influence of various numbers of turns per coil and the emission magnetic torque on the turn-off time with the same point and the same parameters. The results show that the turn-off time of the same device and the same parameter is greatly influenced by the transmitting coil resistance;The set of transmitter superposition number and the choice of time series have little effect on the turn-off time; The turns per coil and turn-off time has a positively linear relationship; The transmitting magnetic moment of coil and turn-off time has a positively linear relationship under the condition of invariable in the turns per coil.
