An Optimal Design Method of Pressure Grading Ring Based on Finite Element and Deep Belief Network

Abstract

The present invention provides an optimal design method for a pressure equalizing ring based on finite element and deep belief network. The invention constructs a training sample set and a test sample set for optimizing the structural parameters of the pressure equalizing ring; trains the training sample set through a deep belief network to obtain a deep belief network after training, which is used to fit the structural parameters of the pressure equalizing ring and the maximum along the surface. The relationship between the electric field strengths; carry out multiple deep belief network training, use the deep belief network after training to calculate the output of the test sample, that is, the maximum electric field strength along the surface, and compare it with the maximum electric field strength along the surface in the test sample set to obtain the average absolute According to the genetic algorithm, the optimal solution of the structural parameters of the pressure equalizing ring is obtained; the invention greatly reduces the number of tests and time, and improves the work efficiency.

Description

technical field [0001] The invention relates to the field of high-voltage insulation, in particular to an optimal design method for a voltage equalizing ring based on a finite element and a deep belief network. Background technique [0002] The square wave power supply for on-site testing of the DC measuring device can provide on-site calibration for the high-voltage DC current transformer to ensure the safe operation of the DC transmission system. The energy storage component is an indispensable core part of the square wave power supply used in the field test of the DC measurement device. Its function is to store energy and release it at an appropriate time. Since the high voltage is applied to the top of the energy storage module, coupled with the shape characteristics of the energy storage module and the low conductivity of the insulating shell, the potential distribution starts to decay rapidly from the high voltage end, and the voltage distribution is extremely uneven, ...
