Abstract

The invention relates to an optimization method and system for a composite dry-type wall bushing structure, and belongs to the technical field of structure optimizing.The method comprises the steps that firstly, constraint conditions of all parameters of the composite dry-type wall bushing structure are determined, and a multi-objective function is constructed with the weight minimization of the structure and the field intensity minimization of a preset position as targets; and then, on the basis of the constraint conditions, with the optimization of the multi-objective function as a target, optimizing each parameter of the structure by adopting an optimization algorithm. In order to obtain a wall bushing structure which can consider the minimum weight and the optimal electric field of a key part, a structure parameter design problem is converted into a multi-target and multi-constraint optimization problem to be solved, and an optimization algorithm is used for solving, so that the calculation speed can be increased and the calculation is closer to an overall optimal solution.

Description

technical field [0001] The invention relates to the technical field of structure optimization, in particular to a structure optimization method and system of a composite dry-type through-wall casing. Background technique [0002] With the development of the electric power industry, as a new generation of high-voltage power transmission and transformation products, composite dry-wall bushings are gradually used to replace porcelain wall bushings, mainly used for electrical insulation of high-voltage conductors, vacuum circuit breaker inlet and outlet lines, etc. and support. The structural optimization design in the composite drywall bushing mainly focuses on the use of simulation methods. However, the use of simulation methods can only optimize local key parts, and cannot comprehensively consider the influence of multiple factors on multiple mutually exclusive targets. SUMMARY OF THE INVENTION [0003] In view of this, the present invention provides a method and system f...
