【Abstract】 Vacuum switch which uses the new type permanent magnetic actuator (PMA), has much higher operating accuracy and reliability. Based on the establishment of mathematic model, this paper analyses dynamic behavior of the PMA. In the test, the open and closing speed of vacuum switch are measured, and the comparison of theoretical and experimental results shows that the mathematic model and the calculation method are correct and reliable.更多还原
