摘要
分析厂用电切换时施加在电动机群上的电压,即母线残压的变化过程;指出为提高快速切换成功率,应根据实际情况确定允许的合闸相角差;提出新型切换装置应具备快速切换、同期捕捉切换、残压切换功能。
This paper analyses the change process of the voltage applied on the motor groups the residual voltage in generatrix when the house supply is transfered. In order to improve high-speed switch power efficiency, the permissible close phase drops are determined according to the fact. And the new transfer equipment has such function：high-speed, synch capture switch and residual voltage switch.
