Расчетная оценка плотности тока смещения и ее влияния на электромагнитные процессы в металлическом проводнике с переменным током проводимости

Abstract

The results of approximate calculations of the density delta;st of the displacement current ist and the estimation of its influence on electromagnetic processes in the homogeneous non-magnetic metals alloys of a continuous cylindrical conductor of finite sizes radius r0 and length l0r0 with an electric variable pulse axial current i0t of different amplitude and temporal parameters. The theoretical data obtained for the quantized discrete spatiotemporal distributions of standing longitudinal waves half waves of the displacement current ist at density delta;st in the indicated conductor leads to the following conclusion. In the electrodynamic calculations of variable pulse electromagnetic processes that occur both in this conductor and in an electric circuit in it, it is possible to neglect the influence of longitudinal waves half waves of the displacement current ist at density delta;st and of the displacement current ist itself at the practical field calculations. It is found that the waves half waves of the displacement current ist at density delta;st and of the displacement current ist maintain solenoidality of the total electric current of iit = i0t+ ist in the conductor and its circuit. The calculations has shown that the displacement current ist and its density delta;st in a non-magnetic metal alloy of the studied conductor do not lead to thermal joule energy losses.

Приведены результаты приближенного расчета плотности delta;st тока смещения ist и оценки ее влияния на протекание электромагнитных процессов в изотропном немагнитном металле сплаве сплошного цилиндрического проводника конечных размеров радиусом r0 и длиной l0r0 с электрическим переменным импульсным аксиальным током проводимости i0t различных амплитудно-временных параметров. Полученные теоретические данные для квантованных дискретных пространственно-временных распределений стоячих продольных волн полуволн плотности delta;st тока смещения ist в указанном проводнике позволяют заключить, что в электродинамических расчетах переменных импульсных электромагнитных процессов, протекающих как в этом проводнике, так и в электрической цепи с ним связанной, влияние продольных волн полуволн плотности delta;st тока смещения ist и самого тока смещения ist в нем можно не учитывать и этими величинами при практических полевых расчетах можно пренебрегать. Установлено, что волны полуволны плотности delta;st тока смещения ist и самого тока смещения ist сохраняют соленоидальность замкнутость полного электрического тока iit = i0t + ist в проводнике и его цепи. Расчетным путем показано, что ток смещения ist и его плотность delta;st в немагнитном металле сплаве исследуемого проводника тепловых джоулевых потерь энергии не несут.
