16 absorption；After the energization of electromagnet 1, dynamic iron core 3 is by electromagnetic force to the right, and compressed spring 17 is also carried for dynamic iron core 3
For active force to the right, in this way, dynamic iron core 3 is under the force action of electromagnetic force to the right and the active force of compressed spring 17 to the right
It moves right, compressed spring 17 can increase thrust to the right so that the thrust increase that electromagnet 1 exports, in this way, using power consumption
Smaller electromagnet 1 just can generate larger thrust to meet the dropout requirement of swivel mount 14 and retaining arm 11.The absorption dress
It puts and permanent magnet may be used to adsorb dynamic iron core 3, it is further preferable that the magnetic attracting device 16 includes magnet steel 18 and set on magnet steel 18
The magnetic conductive board 19 on right side, the left end of compressed spring 17 are against on magnetic conductive board 19.Magnet steel 18 can generate the magnetic of absorption dynamic iron core 3
, magnetic conductive board 19 enhances magnetic field caused by magnet steel 18 and generates adsorption capacity to dynamic iron core 3.Dynamic iron core 3 and magnetic attracting device 16 it
Between be equipped with compressed spring 17, as a preferred embodiment, as shown in Fig. 2, left section of the dynamic iron core 3 have diameter it is small
In the spring coupling part 20 of 3 right sections of diameters of dynamic iron core, the right end of spring coupling part 20 has annular abutment face 21, the compression bullet
Spring 17 is sleeved on spring coupling part 20, and the right end of compressed spring 17 is against on the annular abutment face 21, a left side for compressed spring 17
End is against on magnetic attracting device 16.The electromagnet 1 has electromagnetic coil 22, and electromagnetic coil 22 has the centre bore of left and right extension
23, the dynamic iron core 3 is threaded through in centre bore 23, and when electromagnetic coil 22 is powered, dynamic iron core 3 is in the magnetic field that electromagnetic coil 22 generates
Under the action of move right.Preferably, the compressed spring 17 is set in the centre bore 23 of electromagnetic coil 22,17 sets of compressed spring
Set on 3 outside of dynamic iron core.
In a kind of tripping mechanism of breaker of the utility model, electromagnet 1 generates driving force for tripping mechanism, such as schemes
Shown in 2, when the dynamic iron core 3 moves right under the driving of electromagnetic coil 22, dynamic iron core 3 pushes away to the right the lower end for compressing arm 12
And the right end of the retaining arm 11 is driven to rotate upward, so as to which the upper end of swivel mount 14 be made to be detached from the card slot 13, the tension spring
15 pulling swivel mounts 14 and make the upper end of swivel mount 14 towards right rotation.As a preferred embodiment, the retaining arm 11
Right end there is a downward projection of card prominent 24, the left side of card prominent 24 is the card slot 13, and the upper end of the swivel mount 14 is towards the right side
It is pressed on the left side of card prominent 24, the width of the left side of card prominent 24 along the vertical direction is set according to actual needs.
Technical solution based on above-described embodiment, a kind of tripping mechanism of breaker of the utility model can be breaker
Lock or trip operation are provided, it is simple in structure, cost is relatively low.It is moreover, because defeated there is provided electromagnet dynamic iron core is helped to improve
