摘　　要：高压隔离开关是电网中广泛使用的开关设备,其性能的好坏直接决定了用电安全。为评价GW46-126型高压隔离开关在不同环境温度下的使用性能,在气候试验室±60℃温度环境范围内,对隔离开关的触头接触压力、动静触头相对位置、机构操作扭矩、机构输出角等机械参数和电学参数回路电阻随温度变化的规律进行试验研究。通过试验数据采集和分析,确定环境温度变化对隔离开关机械特性和电学特性的影响,为进一步优化GW46-126型高压隔离开关性能和提高环境温度适用性提供了重要的理论支持。High voltage isolation switch was widely used in power grid.Its performance directly determined the safety of electricity consumption.In order to evaluate the performance of GW46-126 high voltage isolation switch at different ambient temperatures,the experimental studies on the contact clamping force,contact relative position,mechanism operating torque,output angle of mechanism,circuit resistance and other parameters of the isolation switch within the temperature range of±60℃in climate laboratory were conducted to get the relationship between the qualities and temperature.Through experimental data collection and analysis,the impact of environmental temperature change on the mechanical and electrical characteristics of isolation switch was determined,which could provide important theoretical support for further optimizing the performance of GW46-126 high-voltage isolation switch and improving the applicability of environmental temperature.
