[Abstract]:A new type of permanent magnet AC contactor with break protection device is proposed. The contactor is divided into two parts: the mechanism part and the control circuit part. When the control circuit of the permanent magnet contactor is out of power or the demagnetizing coil is out of order, the protection device will be triggered, forcing the contactor core to overcome the suction of the permanent magnet. A control circuit is designed to work with contactor. The circuit is divided into two parts: normal working circuit and protective circuit. The normal working circuit is responsible for controlling the contactor to perform normal breaking and sucking operation, while the protection circuit is responsible for detecting and triggering the protective device for forced break protection. In order to improve the reliability of the circuit, the protection circuit is designed by logic circuit without CPU control unit. At the same time, in order to improve the reliability of power supply, the protection circuit and the normal working circuit power supply are designed separately. The main contactor contact is used to supply the power supply with 380 V line voltage. The delay between the break control voltage and the auxiliary contact voltage is studied experimentally, and the delay is used as the design reference of the protection circuit. The experimental results show that the new AC permanent magnet contactor can effectively solve the problem that the permanent magnet contactor can not be broken when the normal working circuit is out of power or when the fault occurs. The reliability of permanent magnet contactor is greatly improved.
