Comparative Analysis of Two Actuators for High Voltage Bypass Switch

The bypass switch is required to complete the closing operation quickly and accurately protect the transmission line. Therefore, there is a high requirement for the actuator of the bypass switch. According to the characteristics of the bypass switch, the commonly used actuators are compared, and the magnetic force actuator and the motor actuator are initially selected to meet the requirements. Firstly, the characteristics of the magnetic and motor actuator are compared and analyzed in principle. Then, the optimization model of the two actuators is obtained through simulation optimization. Under the same working voltage, the action characteristics of the two actuators, including the action speed, the start time and the output force, are compared. Finally, a comprehensive reference for the selection of the bypass switch actuator is provided.
