[0002] In existing power systems, switchgear is typically used to control and distribute electrical energy. However, in the event of a planned or temporary power outage, existing switchgear cannot quickly select a backup power source for production operations, which may interrupt the production process and cause economic losses to the company. Utility Model Content

[0003] The problem to be solved by the present application is that when the existing switch cabinet encounters a planned power outage or a temporary power outage, it is unable to quickly select a backup power supply for production operations, thereby causing an interruption in the production process.

[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example

[0016] The present application relates to a power-off-proof switchgear cabinet, such as Figure 1-8 As shown, the switch cabinet includes a cabinet body 3 for serving as a basic support, a cabinet door 2 that can be flipped open and closed is arranged in front of the cabinet body 3, a frame 7 for serving as an installation support is arranged inside the cabinet body 3, and columns 4 and beams 5 for installation and positioning are arranged on the upper part of the frame 7. There are two columns 4, which are vertically and symmetrically arranged at the center line positions on both sides of the height direction inside the cabinet body 3, and a plurality of evenly and spaced horizontal beams 5 for lateral support are arranged between the columns 4. On the upper part of the beams 5 is arranged a power transmission component 1 for connecting to an external power grid for power transmission operations. In order to be able to effectively respond to planned power outages or temporary power outages to avoid interruption of the production process due to power outages, a switching component 6 for circuit switching is also provided between the power transmission component 1 and the external power grid.

[0017] The power transmission component 1 includes a busbar 21, a transverse bar 23, and a circuit breaker 24. There are two groups of busbars 21, which are arranged side by side inside the cabinet 3 for connecting to different external power supply lines respectively. The lower end of the busbar 21 is provided with a transverse bar 23 placed horizontally inside the cabinet 3 to connect the two groups of busbars 21. There are multiple circuit breakers 24, which are evenly and spaced horizontally on the upper part of the crossbeam 5. The input end of the circuit breaker 24 is evenly and spaced with incoming line bars, which are connected to the transverse bar 23 in turn to transmit electric energy. The output end of the circuit breaker 24 is evenly and spaced with outgoing line bars, which are used to connect to external electrical appliances. Since the outgoing line bars are easily affected by the length of the electrical wires of the electrical appliances and are easily deformed or dislocated, and the outgoing line bars are divided into live, neutral and ground terminal terminals, in order to avoid short circuits of the live, neutral and ground terminal terminals of the outgoing line bars, spacers 25 that serve as insulating separators are evenly and spaced at the output end of the circuit breaker 24.

[0018] The switching assembly 6 includes a switch part and a driving part. The switch part is divided into a fixed part and a movable part according to the form of activity. The fixed part is fixedly arranged on the upper part of the beam 5, and the movable part is arranged on the upper part of the fixed part and can rotate around it. The power on and off operation can be achieved by controlling the opening and closing between the movable part and the fixed part. In order to achieve the opening and closing between the two, a driving part for driving the movable part to perform flipping and opening and closing operations is arranged on one side of the fixed part.

[0019] The fixing parts include a bracket 16, a contact base 14, and a shield 15. The bracket 16 is fixedly arranged on the back of the beam 5. The upper half of the bracket 16 is provided with a contact base 14 fixedly connected to it for communicating with the power supply line. The outer sleeve of the contact base 14 is provided with a shield 15 for protecting it from arc extinguishing when it is turned on and off.

[0020] The movable parts include a support plate 20, a contact 17, and a spring plate 18. The support plate 20 is fixedly arranged on the lower half of the bracket 16. The contact 17 is arranged on the upper part of the support plate 20, which rotates around and opens and closes with the contact base 14. In order to ensure that the contact 17 and the contact base 14 are stably engaged, a spring plate 18 is also arranged on the outside of the contact 17 to perform an elastic compression function.

[0021] The driving part includes a support frame 8, a support plate 13, a gear sleeve 9, a gear rod 10, a rocker arm 11, a connecting frame 12, and a connecting rod 19. The support frame 8 is placed horizontally inside the frame 7. A support plate 13 fixedly connected to the support frame 8 is arranged on the upper part of the support frame 8. A rotatable gear sleeve 9 is arranged through the center position of the length direction of the support plate 13. A gear rod 10 meshing with the gear sleeve 9 is arranged through the center position of the width direction of the support plate 13. A rocker arm 11 connected to the gear sleeve 9 and rotating synchronously with the gear rod 10 is arranged on the upper part of the gear rod 10. The connecting rod 19 is placed horizontally on one side of the bracket 16 and is connected to a plurality of contacts 17. The connecting frame 12 passes through the bracket 16 and is used to connect the rocker arm 11 and the connecting rod 19 respectively. Since the connecting frame 12 will be driven by the rocker arm 11 to swing in the vertical direction, a straight slot for the connecting frame 12 to swing is arranged on the upper part of the bracket 16.

[0022] During use, when facing a planned power outage or a temporary power outage, by rotating the gear sleeve 9, the gear rod 10 can be driven to rotate with the help of the meshing link, and the gear rod 10 can drive the rocker arm 11 to swing synchronously, thereby driving the connecting frame 12 to swing vertically inside the straight slot. At the same time, it will drive the connecting rod 19 to drive multiple contacts 17 to flip around the support plate 20, thereby realizing the opening and closing operation between the contacts 17 and the contact seat 14, so that the horizontal row 23 can be connected to different transmission lines, and the circuit breaker 24 placed at the bottom of the horizontal row 23 can also be synchronously connected to different transmission lines, so that the electrical appliances can continue to work. In order to ensure the stability of the transmission line, a current detection function mutual inductor 22 is also connected in series to the upper part of the busbar 21.
