| Abstract: | The mathematical model of the dynamic closing process is established by analyzing the dynamic process of contactors. A dynamic testing system of AC contactors based on Laser Probing Displacement Sensor is designed to study the dynamic process of contactors. The Parameters of contactors＇ displacement, speed, current and voltage can he obtained simultaneously by this high-speed and high-precision testing system. The relation among closing phase angle, voltage and dynamic process of contactors can be obtained by this testing system as well to provide the basis for optimizing contactors＇ dynamic process, thereby being able to reduce the end speed of closing armature, shorten contact bounce, improve the working performance of contactors, and prolong their working lives. |
