真空断路器动作特性受运动阻尼影响的研究
Research on Performance Characteristic of Vacuum Circuit Breaker Being Affected by Motion Damping
摘要
Abstract
In research on performance characteristic of vacuum circuit breaker being affected by temperature,it was discovered that motion damping of each mechanism had peculiarity and varied with changes of temperature.In order to study influence of different motion damping on performance characteristic of the vacuum circuit breaker,variable-temperature experiment on multiple vacuum circuit breakers of the same type was conducted and universality law of motion damping affecting performance characteristic of the vacuum circuit breaker under temperature was obtained.By comparing multi-group temperature experiments on breakers,change law of motion damping with temperature was obtained.Quantitative analysis on motion damping was carried out by combining with ANSYS simulation and MATLAB matching was used to obtain relationship formula between damping and trip under different temperature.Research indicates that for the vacuum circuit breaker,difference of motion damping will make performance characteristic change and influence of damping difference under low temperature is larger than that under high temperature.In addition,quantitative value of motion damping in switching-in of the breaker decreases firstly with environmental temperature rise and then increases slightly.关键词
