Abstract

The present invention relates to an electromagnet mechanism for a circuit breaker. The electromagnet mechanism comprises: a stationary armature, having an attraction portion and an excitation member mounted on the attraction portion, the excitation member being used for conducting current of a circuit breaker and generating a magnetic field; and a movable armature, fixedly mounted on a movable armature support. The movable armature support is rotatably mounted on a stationary armature support. The movable armature has an adsorption end. When the excitation member generates the magnetic field, the movable armature rotates towards the stationary armature under the action of electromagnetic torque. The movable armature is configured to be capable of moving between an alignment position and an offset position. In the alignment position, the adsorption end of the movable armature is aligned with the attraction portion of the stationary armature. In the offset position, the adsorption end of the movable armature deviates relative to the attraction portion of the stationary armature, so that a magnetic line path from the movable armature to the stationary armature is deflected, thus reducing the electromagnetic torque required for rotating the movable armature towards the stationary armature, increasing demagnetizing current of the circuit breaker in the offset position, and finally increasing the magnetic modulation range of the circuit breaker.

The first high-side control unit (110) and the second high-side control unit (160) connect a first magnetic unit (120) and a second magnetic unit (125) of the contactor respectively to a power supply (105). The first low-side control unit (130) is connected between the first magnetic unit (120) and a reference voltage node (115), and the second low-side control unit (135) is connected between the second magnetic unit (125) and the reference voltage node (115). The control device (100) further comprises a free-wheeling unit (150) connected to the first magnetic unit (120) and the second magnetic unit (125). The control device (100) further comprises a controller (170). The controller (170) is used for controlling the operation of each control unit, so that in a state where the connection between at least one magnetic unit of the first magnetic unit (120) and the second magnetic unit (125) with the power supply (105) is disconnected, the current of the at least one magnetic unit flows through the free-wheeling unit (150). The solution can enable the contactor to be more energy-saving and reduce operating cost.

The control device comprises a high-side control unit (110), a first low-side control unit (130), a second low-side control unit (135), a flyback unit (150), and a controller (155). The high-side control unit (110) is configured to make or break connections between a first magnetic unit (120) and a second magnetic unit (125) of the contactor and a power supply (105). The first low-side control unit (130) is configured to make or break a connection between the first magnetic unit (120) and a reference voltage node (115). The second low-side control unit (135) is configured to make or break a connection between the second magnetic unit (125) and the reference voltage node (115). The flyback unit (150) is connected across a branch comprising the first magnetic unit (120) and the first low-side control unit (130), and connected across a branch comprising the second magnetic unit (125) and the second low-side control unit (135). The controller (155) is configured to control operation of the high-side control unit (110), the first low-side control unit (130), and the second low-side control unit (135). Intelligent control to the contactor can be achieved using simple control logic.
