摘要： An electromagnetic actuator has: an armature carrying at least one coil; a ferromagnetic yoke configured to channel a magnetic flux created by the coil; and a ferromagnetic moving part that interacts with the yoke to form a magnetic circuit formed at least in part by an assembly of laminated metal plates, the moving part being configured to move in relation to the armature under the action of the magnetic field generated by the coil. The actuator moreover has an auxiliary magnetic circuit made of electrically conductive material, in order to permit the flow of currents induced in the auxiliary magnetic circuit when a magnetic field is generated by the coil.

摘要： An electrical distribution system, for distributing electrical currents between an electrical distribution network and a domestic distribution installation, includes: a multi-source electrical switching unit allowing or preventing the circulation of electrical currents in two electrical conduction paths each including a plurality of electrical conductors, and an electrical connection device connected at the output of the electrical switching unit, the connection device being configured to prolong the two electrical conduction paths at the output of the switching unit. The electrical switching unit is configured to connect, on a first input, a first of the two electrical conduction paths to an electrical distribution network, the electrical switching unit being configured to connect, on its second input, the second of the two electrical conduction paths to an auxiliary electrical source. The connection device is configured to connect each electrical conduction path to one or more electrical loads at the output of the electrical switching unit. The electrical connection device includes an interconnection point in which the corresponding electrical conductors of each electrical conduction path are connected to one another, the multi-source electrical switching unit forming a single disconnection point capable of simultaneously disconnecting the electrical sources connected to the first input and to the second input from the rest of the electrical distribution network.

摘要： The present disclosure relates to a contactor and an operation method thereof. The contactor includes a contact, a control device, a wear indication and reset device, and a memory. The control device generates and stores wear diagnosis alarm information when the contactor is disconnected; generates a switch control signal based on the wear diagnosis alarm information when the contactor is powered on. A switch unit in the wear indication and reset device enters a wear indication state based on the switch control signal, and receives a user's operation to enter a reset state. The control device receives switch state information of the switch unit, and stores it when the contactor is disconnected. When the contactor is powered on, the control device clears the wear diagnosis alarm information based on the received switch state information being the reset state and the switch state information stored being the wear indication state.

摘要： Embodiments of a software defined automation system that provides a reference architecture for designing, managing and maintaining a highly available, scalable and flexible automation system. In some embodiments, an SDA system can include a localized subsystem including a system controller node and multiple compute nodes. The multiple compute nodes can be communicatively coupled to the system controller node via a first communication network. The system controller node can manage the multiple compute nodes and virtualization of a control system on a compute node via the first communication network. The virtualized control system includes virtualized control system elements connected to a virtual network that is connected to a second communication network to enable the virtualized control system elements to control a physical control system element via the second communication network connected to the virtual network.

摘要： Embodiments of the present disclosure relate to a control device and method for a contactor. The control device comprises a first high-side control unit, a second high-side control unit, a first low-side control unit and a second low-side control unit. The first high-side control unit and the second high-side control unit respectively connect a first magnetic unit and a second magnetic unit of the contactor to a power supply. The first low-side control unit is connected between the first magnetic unit and a reference voltage node, and the second low-side control unit is connected between the second magnetic unit and the reference voltage node. The control device further comprises a freewheel unit connected to the first magnetic unit and the second magnetic unit. The control device further comprises a controller. The controller is used to control operations of the control units so that in a state that at least one magnetic unit of the first magnetic unit and the second magnetic unit is disconnected from the power supply, a current of the at least one magnetic unit flows through the freewheel unit. According to embodiments of the present disclosure, the contactor may be made more energy-saving, and the operation cost may be reduced.
