摘　　要：对厂用电快速切换装置切换过程引起低压接触器低压释放问题进行分析的同时,结合试验数据提出无扰动切换的时间概念。对装置切换判据、采样计算周期及程序触发逻辑进行完善和优化,提高切换装置的切换速度,实现厂用电高压、低压系统无扰动切换,对参数整定也提出相关建议。At the same time of analyzing low voltage release of low voltage contactor in the process of auxiliary power fast transfer device switching, this paper also presents undisturbed switching time concept based on experimental data. It tries to complete and optimize switching criterion, sampling calculation cycle and trigger logic of the procedure so as to improve switching speed of the device and realize undisturbed switching of the high voltage system and the low voltage system. It pro-poses suggestions about parameter setting as well
