摘要

The magnetic field immunity testing system is vital equipment for International Thermonuclear Experimental Reactor, which is mainly used for electromagnetic compatibility tests in strong magnetic field environments. The test system is mainly composed of a coil structure. In this article, the influence of coil offset on the magnetic field performance of the system is studied. There are 18 degrees of freedom offsets of position and angle on the X , Y , and Z axes of the coil, and different offsets have different effects on the magnetic field performance. The different offset combinations of a single coil and two coils are discussed, and various distributions of magnetic field performance are calculated. Then, according to the law, the calculation method is improved, and a reasonable and effective method is selected to calculate the maximum allowable offset of simultaneous position and angle migration under the premise of extremely many variables. In the article, the influence of the spatial multidegree of freedom coil offset error on magnetic field uniformity is studied, the relationship between multivariable allowable offset and magnetic field error accuracy is analyzed, and the allowable offset under different installation errors is determined. This provides a theoretical basis for the actual installation.
