Embodiment 1）

[0025] The invention mainly carries out optimized structural design aiming at the two characteristics of vacuum switch contact temperature and magnetic induction intensity, and combines the orthogonal gray relational analysis method in the design process to improve the performance of the vacuum switch. Using the orthogonal method and the gray relational analysis method, the L16(4 5 ) orthogonal table, carry out 16 experiments, find out the S / N ratio in which the magnetic induction intensity is expected to be large and the temperature is expected to be small in these 16 experiments, and obtain the optimal design result that the temperature and magnetic induction intensity meet the requirements, and the principal component analysis provides Necessary data analysis.

[0026] The present invention converts a group of possibly correlated variables into a group of linearly uncorrelated variables through orthogonal transformation, and the converted group of variables is called princi...

Abstract

The invention relates to a vacuum switch contact structure optimization design method, which takes the reliability of a vacuum switch contact as an object, reasonably selects five design parameters ofa switch contact diameter, a contact blade thickness, a contact ring, a cup wall thickness and an arc diameter to improve the magnetic induction intensity of the vacuum switch contact, and considersstatistical analysis and a reliability theory. The objective of the invention is to establish a switch contact reliability evaluation standard so as to establish a model. The timely understanding of the working state of the contact has important practical significance for improving the reliability of power supply, and can greatly reduce the fund waste caused by blind periodic maintenance. As a quantitative reference index of each link of high-voltage switch equipment design, production, operation, maintenance strategy making and the like, the switch power equipment can reach a full-life-cyclemanagement mode standard.

Description

technical field [0001] The invention relates to a method for applying orthogonal gray correlation analysis to the optimal design of a vacuum switch contact structure to improve its reliability, which can be used for power equipment such as switches, etc., and belongs to the technical field of power systems. Background technique [0002] If there is no warning failure of vacuum switch contacts, it will cause heavy losses in many industries. In order to avoid such unwarranted power outages and provide stable and safe power quality, the safety maintenance of vacuum switch contacts will become One of the important issues that should be paid attention to. The purpose of reliability evaluation and life prediction of switch monitoring is to detect early signs of failure in time, so that operation and maintenance personnel can eliminate hidden dangers early by means of detection when the accident is in its infancy, thereby avoiding the occurrence of malignant accidents. The monitor...
