液压机构操动的断路器分闸特性受环境温度影响的研究

Effects of Ambient Temperature on the Opening Motion Characteristic of Circuit Breaker with Hgdraulic mechanism

对配液压机构的断路器分闸运动特性进行了分析,建立了描述断路器分闸过程的数学模型.研究显示,环境温度变化对断路器分闸运动特性影响很大.因此提出了温度变化对断路器分闸运动特性影响的补偿原理.

The opening motion characteristic of circuit breaker equipped with hydraulic mechanism is analyzed. The mathematical model of the opening process is developed. The results show that such characteristic is greatly affected by the ambient temperature. Therefore the compensation for the change of such characteristic with temperature is put for-ward.
