چکیده:

This paper presents a new method called vespiary regular hexagonal (VRH) model in order to calculate parasitic capacitance between conductor wire filaments of one turn of coil (OTC) and between conductor wire filaments and liner and also total capacitance of n turns having multi-layers conductor wires filament of the coil of helix magneto flux cumulative generator (MCG) in the form of rectangular cross-section. Method presented in this paper is based on an analytical method and geometrical structure of multilayer wire filaments. In this paper, wire filaments of the coil are separated into many very small similar elementary cells. In this structure, an equilateral lozenge-shape basic cell (ELBC) with two trapezium-shape regions is considered between two adjacent conductor wire filaments in one turn of the generator coil. This method applies to calculate stray capacitance of n turn of the coil with multi conductor wire filaments (CWFs). Finally, we will see that by progress of explosion and volume extension of liner and decrease of the number of turns of coil of the generator until the second turn, total capacitance of generator increases and when there remains only one turn in the circuit, there occurs a descending decrease in total capacitance of the generator.
