    摘要： The invention relates to a highly dynamic electromagnetic drive in the manner of a Thomson coil with soft-magnetic frame, comprising a first excitation coil (30) whose winding height is greater than its length, which hence is flat; a soft-magnetic frame (10) in which the first excitation coil (30) is arranged and against which it abuts, and which in in the manner of a pot magnet constitutes an open magnetic circuit which includes an outer region (11), a bottom (12) and an inner region (13), and which is open on its end face, wherein the first excitation coil at least partly encloses the inner part (13) of the frame; a short circuit armature (40) preferably formed hollow cylindrical at least on its side facing the first excitation coil (30), which is movably mounted along an axis and which in its stroke starting position dips into the end-face opening of the frame (10) and thereby at least partly encloses the inner part of the frame (13), wherein the frame (10) entirely or predominantly is formed of a soft-magnetic composite material or one or more sheet stacks, which has a saturation flux density of at least 1.5 T and an effective specific electrical conductivity of not more than 106 S/m, and the first excitation coil (30) and/or the frame (10) include at least one means for strain relief, in particular in the form of an enclosure in order to at least partly absorb at least the radial forces occurring on the first excitation coil (30) during an actuating operation vertically to the direction of movement, and wherein the Lorentz force acting on the short circuit armature is used to perform work.

    摘要： A quick tripping device of a circuit breaker having a contact system that includes a moving contact mechanism and a static contact, wherein the moving contact mechanism includes a contact support and a moving contact, and a contact spring having, two ends connected with the moving contact and the contact support respectively. The quick tripping device further includes a first transmission structure in driving fit with the contact spring and rotatable rotates along with the contact spring. When a short-circuiting current flows through the contact system, the moving contact is repelled by an electric repulsive force between the moving contact and the static contact, so that the moving contact rotates relative to the contact support. The moving contact drives the first transmission structure to rotate through the contact spring, and the first transmission structure drives an operating mechanism to trip.

    摘要： A power circuit breaker has a housing defining a first passage and a cross passage through the housing. A bus bar extends through the cross passage and is configured to transmit electric power and/or break transmission of the electric power through the housing. The bus bar includes at least an input section, a coin or center section, and an output section that are separable from each other. The housing aligns a solenoid piston within the first passage of the housing. The solenoid has a piston with two opposite ends, and one of the ends operates as a plunger to separate the sections of the bus bar when the solenoid is actuated. The plunger moves the coin or center section of the bus bar out of contact with the input section and the output section of the bus bar to break electrical transmission across the bus bar.

    摘要： An operating mechanism of a circuit breaker includes a moving contact bracket, a moving contact assembly, and a reset torsion spring. The moving contact bracket is provided with a rotating shaft, and the moving contact bracket may be rotated around the rotating shaft; a first end of the reset torsion spring is arranged on a base of the circuit breaker, and a second end of the reset torsion spring is arranged on the moving contact assembly; the moving contact assembly is rotatably arranged on the moving contact bracket, and the moving contact bracket is provided with a limiting portion, so that in a closing process of the circuit breaker, the moving contact assembly is pressed against the limiting portion and rotated synchronously with the moving contact bracket, and the reset torsion spring applies a force rotated towards a disconnection direction of the circuit breaker to the moving contact bracket.

    摘要： Circuit interrupter devices have a first housing with a circuit interrupter, a second housing coupled to the first housing, a ground fault circuit and current transformer in the second housing. The current transformer has an open channel. The circuit interrupter devices also include at least one power conductor having a rigid or semi-rigid body with opposing first and second end portions extending between the first and second housings. The second end portion of the at least one power conductor extends through the open channel in the current transformer and terminates in a breaker load collar(s).
