摘　　要：本文通过搭建550kV断路器选相控制试验平台,分别研究了选相控制器自身准确度、断路器分闸/合闸时间分散性、外部变量对断路器分闸/合闸时间的影响,获取了控制电压、环境温度、机构油压、间歇时间和气室压力这5个环境变量的补偿曲线,通过在选相控制器中植入外部变量补偿功能,实现选相控制器根据外部变量自动修正断路器的分闸/合闸时间,达到了在预期相位分闸/合闸断路器的目的,提高了高压断路器选相控制的准确性。This paper through the construction of 550kV circuit breaker phase selection control test platform,the accuracy of the phase selection controller itself,the dispersal of the circuit breaker opening/closing time,and the influence of external variables on the opening/closing time of the circuit breaker are studied respectively,obtained compensation curves for five environmental variables of control voltage,environment temperature,mechanism oil pressure,chamber pressure and intermittent time,by implanting an external variable compensation function in the phase selection controller,the phase selection controller automatically corrects the switching time of the circuit breaker according to the external variable,and achieves the purpose of splitting the circuit breaker in the expected phase,improve the accuracy of phase selection control of high voltage circuit breakers.
