The quick-plug connector 13 is used to connect the power output connector of the generator. The busbars 12 correspond to the quick-plug connectors 13 one by one, and the busbars 12 are connected to the corresponding quick-plug connectors 13. Four protective covers 14 for protecting the quick-plug connectors 13 are rotatably installed on the outer side of the fixed frame 11, and the protective covers 14 are arranged on the outer side of the quick-plug connectors 13. A contact switch 15 for controlling the on and off of the circuit breaker is arranged on the side of the cabinet 1, and a cover plate 16 is installed on the side of the fixed frame 11. The cover plate 16 is fixedly connected to the fixed frame 11 by bolts, and the cover plate 16 can contact the contact switch 15 and keep the circuit breaker powered on.

[0043] The implementation principle of Example 1 of the present application is as follows: when the low-voltage switch cabinet is in normal working condition, the cover plate 16 is fixedly connected to the fixed frame 11 by bolts, and the cover plate 16 abuts against the contact switch 15, so that the circuit breaker is in a power-on state; when a power outage occurs in the low-voltage switch cabinet, it is necessary to use a generator to generate electricity, and the cover plate 16 is removed. At this time, the contact switch 15 is no longer squeezed by the cover plate 16, and the circuit breaker is disconnected from the power supply to avoid affecting the operational safety when the low-voltage switch cabinet suddenly resumes power supply, and then the protective cover 14 is lifted up, and the generator is connected to the busbar 12 through a quick-connect plug, thereby realizing the quick connection of the generator. Example

[0045] Reference Figure 5 and Figure 6 Two symmetrically arranged connecting plates 22 are fixed to the side of the pressing plate 21 close to the fixed plate 2. A connecting groove 23 is provided on the side of the fixed plate 2. The connecting plate 22 slides and cooperates with the fixed plate 2 along the thickness direction of the fixed plate 2 through the connecting groove 23. A sliding block 24 is fixed to the side of the connecting plate 22. A sliding groove 25 is provided on the inner wall of the connecting groove 23. The sliding block 24 slides and cooperates with the fixed plate 2 along the thickness direction of the fixed plate 2 through the sliding groove 25. A spring 26 is fixed to the side of the sliding block 24 away from the pressing plate 21. One end of the spring 26 away from the sliding block 24 is fixedly connected to the inner wall of the sliding groove 25.

[0046] Reference Figure 6 and Figure 7 Two symmetrically arranged plug-in plates 27 are fixed to the side of the pressure plate 21 close to the fixed plate 2. A plug-in slot 28 is provided on the side of the fixed plate 2. The plug-in plate 27 slides and cooperates with the fixed plate 2 along the thickness direction of the fixed plate 2 through the plug-in slot 28. A limiting slot 31 is provided on the inner wall of the plug-in slot 28. The fixed plate 2 slides and installs the limiting block 3 along its own width direction through the limiting slot 31. A positioning slot 271 for inserting the limiting block 3 is provided on the side of the plug-in plate 27. A spring 2 33 is fixed to the side of the limiting block 3 away from the plug-in plate 27. One end of the spring 2 33 away from the limiting block 3 is fixedly connected to the inner wall of the limiting slot 31. An inclined surface 1 32 is provided on the side of the limiting block 3 away from the spring 2 33. The inclined surface 1 32 is located on the side of the limiting block 3 close to the pressure plate 21.

[0047] When the plug-in board 27 is inserted into the plug-in slot 28, the plug-in board 27 abuts against the inclined surface 1 32, thereby pushing the limit block 3 into the limit slot 31. When the pressing plate 21 abuts against the contact switch 15, the positioning slot 271 is aligned with the limit slot 31. The limit block 3 is inserted into the positioning slot 271 under the elastic force of the spring 2 33, so that the pressing plate 21 abuts against the contact switch 15, thereby keeping the circuit breaker powered on.

An electromagnet 45 is fixed on the inner top surface of the driving groove 44, and the electromagnet 45 can attract the iron block 43 after being energized.

[0049] When the electromagnet 45 is powered on, the electromagnet 45 attracts the iron block 43, and the iron block 43 moves upward, thereby driving the movable plate 4 to move upward.

When the protective cover 14 is not subjected to external force, the rotating rod 5 drives the protective cover 14 to rotate downward under the action of the torsion spring 51, so that the protective cover 14 fits the fixed plate 2, thereby realizing the protection of the quick-connect plug.

[0051] Reference Figure 5 and Figure 8 A rotating cavity 53 is provided in the fixed plate 2, and a horizontally arranged connecting rod 52 is rotatably installed in the rotating cavity 53.

A stopper rod 522 is fixed at the end of the connecting rod 52, and a connecting block 46 is fixed on the side of the movable plate 4, and the stopper rod 522 can abut against the top surface of the connecting block 46.

[0052] When the staff has not opened the protective cover 14, the resisting rod 522 abuts against the top surface of the connecting block 46, reducing the possibility of the movable plate 4 moving upward when the protective cover 14 is not opened; when the staff has opened the protective cover 14, the rotating rod 5 drives the bevel gear 1 54 to rotate, and the bevel gear 1 54 drives the bevel gear 2 521 to rotate, thereby driving the connecting rod 52 to rotate upward, and the connecting rod 52 drives the resisting rod 522 to rotate upward, and the resisting rod 522 is separated from the connecting block 46, thereby releasing the limit of the resisting rod 522 on the movable plate 4, so that the movable plate 4 can move upward under the action of the electromagnet 45.

[0054] When the protective cover 14 is in the closed state, the protective cover 14 abuts against the control block 6, the spring three 64 is in a compressed state, the reset block 62 is separated from the abutment block 65, and the electromagnet 45 is powered off; when the protective cover 14 is lifted, the reset block 62 moves toward the direction close to the abutment block 65 under the elastic force of the spring three 64, and the reset block 62 is in electrical contact with the abutment block 65. When all four protective covers 14 are lifted, the electromagnet 45 is powered on and works.

[0055] The implementation principle of Example 2 of the present application is as follows: when the staff opens the protective cover 14, the rotating rod 5 drives the bevel gear 1 54 to rotate, and the bevel gear 1 54 drives the bevel gear 2 521 to rotate, thereby driving the connecting rod 52 to rotate upward, and the connecting rod 52 drives the resisting rod 522 to rotate upward, and the resisting rod 522 is separated from the connecting block 46, and the limit of the movable plate 4 by the resisting rod 522 is released. When the four protective covers 14 are all in the open state, the electromagnet 45 is energized to work, and the electromagnet 45 attracts the iron block 43, and the iron block 43 drives the movable plate 4 to move upward, and the movable plate 4 pushes the limit block 3 to move in the direction away from the plug-in board 27, so that the limit block 3 disengages from the positioning groove 271, and the limit of the limit block 3 on the plug-in block is released. The pressure plate 21 is away from the contact switch 15 under the elastic force of the spring 1 26, and the contact switch 15 is no longer squeezed by the pressure plate 21, and the circuit breaker is disconnected from the power supply to prevent the low-voltage switch cabinet from suddenly restoring power supply and affecting the operation safety.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
