摘要
本文将文献[1]的分析方法推广到带铁心的偏转器,绕组形状可以是任意的,如子午绕组、非子午绕组、鞍形、环形或扇形等。对铁心与绕组之间有一定间隙的情况,提出了计算偏转场的一种新的表示式,并用高斯-切比雪夫积分式对积分方程离散求解。最后用COTY GE-14(?)彩显管偏转器的解剖数据验证。
The analysis method used in the previous paper by the authors is extended to the magnetic deflectors with ferromagnetic shield. The shape of the deflector winding may be arbitrary. It may be radial or non-radial, saddle, toroidal or fan-shape, etc.. A set of new expressions for the deflection field is suggested for the case where the windings are spaced by a gap from the shield. The integral equations are solved by Gauss-Chebyshev quadrature. The computation results are checked with the values measured from a deflector of CRT COTY GE-14'.
