摘要

对永磁体、永磁机构和永磁机构真空断路器分别进行了高温试验和低温试验

通过试验验证了温度对永磁体的磁通量、永磁机构的静态吸合力和永磁机构真空断路器的机械特性参数的影响规律。结果表明:永磁体的磁通量和永磁机构的静态吸合力与温度为负相关;同时

永磁机构真空断路器的平均分闸速度、平均合闸速度、分闸线圈电流值和合闸线圈电流值与温度均为负相关。

Abstract

High and low temperature tests of permanent-magnetic（PM）blocks

PM actuators and PM vacuum circuitbreaker are investigated in this paper.The tests verify the influence of temperature on magnetic flux of PM blocks

static magnetic forces of PM actuators and mechanical opening or closing characteristics of PM vacuum circuit breaker.The results show that magnetic flux

static magnetic forces and opening or closing velocities increase with temperature decreasing.Moreover

opening or closing currents increase correspondingly.
