Research on Control Method and the Structure Design of Asynchronous Modular Contactor

Abstract:

Contactors as low-voltage electrical products are largely used, contact bounce when contactor closing and arc which produces during opening is the main factor influencing a contactor’s life. This paper proposed a new structure that asynchronous modular, N-pole contactors consist of N independent contact systems, achieved each contact individually controlled by closed-loop control. This is a new idea in the field of structural design and control of contactors. This paper designed the structure size of the electromagnetic system, used Simulink software to build the model, studied dynamic characteristics of the contacts, and obtained a new closed-loop control method at last. This new method can effectively eliminate contact bounce when the contact closing and the arc generated when breaking, and increases the service life of the contactor.
