Static and Dynamic Characteristics of High Voltage DC Contactors Based on Maxwell

In order to better understand and optimize the action performance of a DC contactor, its static and dynamic characteristics are studied. Firstly, the static characteristics of DC contactor are discussed theoretically, and the reaction force equation is established according to the action process of the contactor. The suction and reaction force curve of static characteristics is analyzed by Maxwell software. Then, the dynamic characteristics of the contactor are analyzed theoreti-cally, and Maxwell software is used to calculate the suction reaction curve, velocity characteristic, displacement character-istic and current characteristic of the dynamic characteristics. Finally, the simulation results are verified by experiments.
