in the figure: the circuit breaker mechanism comprises a circuit breaker mechanism module 1, a rotating piece 2, an excitation coil 3, a magnetic yoke 4, a movable iron core assembly groove 5, a movable iron core 6, a coil framework 7, a return spring 8 and a static iron core 9.
Detailed Description
Referring to fig. 1-5, the present embodiment provides a technical solution: an electromagnetic tripping system of a circuit breaker comprises a circuit breaker mechanism module 1 and a rotating part 2, wherein the top end of the circuit breaker mechanism module 1 is movably connected with the rotating part 2;
rotate top right side fixedly connected with yoke 4 of piece 2, the inside nested coil skeleton 7 that is provided with of yoke 4, the right flank slip embedding of coil skeleton 7 has quiet iron core 9, and the left surface slip embedding of coil skeleton 7 has movable iron core 6, moves fixedly connected with return spring 8 between iron core 6 and the quiet iron core 9, and the outside winding of coil skeleton 7 is provided with excitation coil 3.
Preferably, the middle part of the upper part of the rotating part 2 is provided with a moving iron core assembling groove 5 matched with the moving iron core, when the circuit breaker mechanism module 1 is switched off, the magnetic field in the magnet exciting coil 3 disappears, the pressure of the return spring 8 is released and drives the moving iron core 6 to return to the initial position, and the moving iron core 6 also pushes the rotating part 2 to move to the initial position to prepare for the next work of the electromagnetic tripping system.
Preferably, the circuit breaker mechanism module 1 and the rotating part 2 are arranged in the same horizontal direction, the design can compress the space of the upper position and the lower position of a product graphic, the product is used for the space of a specific occasion, and the size of an external installation cabinet body can be reduced.
Wherein, be equipped with the hasp structure in the circuit breaker mechanism module 1, and the hasp structure is used for circuit breaker mechanism module 1 and rotates 2 buckles of piece.
The working principle is as follows:
firstly, when the excitation coil 3 is electrified, a magnetic field is generated, the movable iron core 6 compresses the return spring 8 to move towards the static iron core 9, and meanwhile, the movable iron core 6 drives the rotating part 2 to move to drive a lock catch in the circuit breaker mechanism module 1, so that the circuit breaker mechanism module 1 is unlocked;
finally, when the circuit breaker mechanism module 1 is switched off, the magnetic field in the excitation coil 3 disappears, the pressure of the return spring 8 is released and drives the movable iron core 6 to return to the initial position, and at the moment, the movable iron core 6 also pushes the rotating part 2 to move to the initial position to prepare for the next work of the electromagnetic tripping system.
