Abstract

The invention discloses a description method of a space electric field of a multi-conductor transmission line system, and aims to accurately and completely describe the space electric field of the multi-conductor transmission line system in detail, and provide a basic method for carrying out electrical parameter calculation and performance index analysis of the multi-conductor transmission line system. The description method comprises the following steps: classifying conductors in the complex multi-conductor transmission line system according to transmission and backflowing functions, and then constructing loops two by two by the different conductors participating in transmission and backflowing, and using the loops, which uniquely correspond to charge in a physical sense, as basic space electric field units; for each loop, deriving and calculating spatial potential differences of all the loops and spatial mutual potential differences between the different loops according to parameters of a radius, a spatial relative distance and the like of the conductors of the loop, and synthesizing the spatial self-potential differences and mutual potential differences to complete electric field description for the single basic space electric field unit; carrying out electric field description on the other basic space electric field units according to the above steps; and synthesizing electric field description equations of all the basic space electric field units, and listing and writing a space electric field description matrix to complete description of the space electric field of the multi-conductor transmission line system.

Problems solved by technology

In the above-mentioned methods commonly used at present, the selection of the reference conductor and the main conductor has a certain degree of randomness, and the basic space electric field unit lacks the strict physical meaning associated with the charge. Therefore, the electric field description of the basic space electric field unit cannot directly reflect the space The effect of any change in the position and size of the charge in the charge reduces the completeness and accuracy of the space electric field description of the multi-conductor transmission line system
