The opening process of free tripping mechanism 1 is as follows:

Combining FIG. 32 and FIG. 33 , FIG. 32 is a schematic diagram of the opening process of the free release mechanism 1 , and FIG. 33 is a top view of each step view in FIG. 32 . The initial state of the opening of the free tripping mechanism 1 is shown in step S Ⅰ in Figure 32, and the step S Ⅰ in Figure 32 is the same as the step S Ⅳ in Figure 27, and the free tripping mechanism 1 is in the closing state at this time, The energy storage disk 41 is in the locked state, that is, the energy storage top plate 412 of the energy storage disk 41 is locked with the trip axle 51 , the energy storage torsion spring 42 is completed, and the energy storage state remains, and the driving disk 21 is in the second position.

When the free tripping mechanism 1 is opened, the first tripping lever 521 rotates counterclockwise N under the control of the opening signal, and pushes the tripping half shaft 51 and the second tripping lever 522 to rotate counterclockwise N, and the opening signal is Refers to the opening signal sent by the control unit 301 when there is a short circuit in the electronic device or power conversion device 100, the tripping shaft 51 rotates counterclockwise N so that the energy storage top plate 412 is located in the second notch 512 and the energy storage plate 41 and the The half-shaft 51 of the trip is unlocked (as shown in step S II in Figure 32 and Figure 33), at this time the energy storage torsion spring 42 releases energy, and the third torsion arm 421 returns to drive the energy storage connection part 414 to rotate counterclockwise N (as Shown in step S IV in Figure 32), so that the energy storage disc 41 rotates counterclockwise N; the second trip lever 522 pushes the trip driver 62 to rotate clockwise S (shown in step S II in Figure 33) , so that the second operating panel 33 is located in the first notch 612 of the tripping half shaft 61 and is unlocked with the tripping half shaft 61, please refer to Fig. 9b, Fig. 9c and Fig. 9d, at this time the tripping half shaft 61, the first An operation disk 32 can rotate counterclockwise N relative to the operation shaft 31 .

When the energy storage disk 41 rotates counterclockwise N when the energy storage torsion spring 42 releases energy, the energy storage protruding part 413 in the energy storage disk 41 drives the first operation panel 32 to rotate counterclockwise through the first locking part 321, at this time If the operating shaft 31 is stuck and unable to rotate, and the tripping half shaft 61 is locked with the second operating disc 33, the first operating disc 32, the tripping semi shaft 61 and the second operating disc 33 remain fixed with the operating shaft 31. The first operation panel 32 cannot be driven to rotate by the protruding portion 413 of the energy storage. In this embodiment, in order to prevent the operation shaft 31 from being stuck when the free tripping mechanism 1 is opened, so that the first operation panel 32 cannot rotate, a trip assembly 60 is provided, that is, when the trip assembly 60 is opened, the trip assembly 60 and the first operation panel 32 cannot rotate. The second operating plate 33 is unlocked, so that the trip assembly 60 and the first operating plate 32 can rotate relative to the operating shaft 31 .

In this embodiment, when the energy storage protrusion 413 is rotated to the position of the closing buckle 12, the closing buckle 12 is pushed outward, wherein the vertical distance between the end of the closing buckle 12 away from the base 11 and the bottom of the base 11 is Greater than the vertical distance between the energy storage protrusion 413 and the bottom of the base 11, the vertical distance between the end of the energy storage protrusion 413 away from the operation shaft 31 and the axis of the operation shaft 31 is equal to the maximum vertical distance between the edge of the first operation plate 32 and the axis of the operation shaft 31 (or equivalent radii).

Wherein the radius of energy storage protruding portion 413 is identical with the radius of drive plate 21, makes energy storage protruding portion 413 push away closing buckle 12, when energy storage torsion spring 42 energy storage is completed, energy storage protruding portion 413 and closing The distance of the buckle 12 is small, so that when the energy storage torsion spring 42 is releasing energy, only the energy storage protrusion 413 needs to be rotated at a small angle to reach the position of the closing buckle 12, so that the opening is more timely and can The elastic energy of the energy storage torsion spring 42 is saved. When the energy storage protrusion 413 pushes the closing buckle 12, the closing spring 13 is compressed, and when the closing buckle 12 is fully pushed away, the driving disc 21 rotates counterclockwise under the action of the driving torsion spring 22 until the opening is opened. When 215 is rotated to the opening position, the opening spring 15 returns to push the opening buckle 14 into the driving opening 215 of the driving disc 21 and locks with the driving disc 21. At this time, the opening of the free tripping mechanism 1 is completed (as shown in Figure 32 Step S IV in and shown in step S IV in Figure 33).

The first operating panel 32, the tripping half shaft 61 and the second operating panel 33 are kept fixed with the operating shaft 31, and the first operating panel 32 cannot be driven to rotate by the energy storage protrusion 413. At this time, the free tripping mechanism 1. Failure to complete the opening process will cause the drive panel 21 to fail to control the circuit disconnection of the electrical equipment in time, thereby affecting normal operation. In this embodiment, by setting the trip assembly 60, when the brake is opened, the trip assembly 50 also drives the trip assembly 60 to unlock the second operation panel 33 and the operation shaft 31 when the energy storage disc 41 is released, so that the first The operation panel 32 can rotate smoothly when the energy storage component 40 releases energy, so that the drive panel 21 can accurately control the free trip mechanism of the electronic device or the power conversion device 100 , and improve the reliability of the remote opening of the free trip mechanism 1 .
