[0001] This utility model relates to the technical field of electronic training, and in particular to the technical field of relay protection training cabinets. Background Technology
[0002] Relay protection devices, developed in recent years, are automated measures and equipment that can promptly issue warning signals to operating personnel or directly issue trip commands to the controlled circuit breakers to terminate the development of these events when power components such as generators and lines, or the power system itself, malfunction and endanger its safe operation. Practical training is an essential component of the training for power plant relay protection operators.
[0003] Chinese utility model patent CN219017103U discloses a training device for relay protection devices. This training device includes a storage box with a through slot at the top. A training component is inserted and installed inside the slot on the top of the storage box. A cooling mechanism is provided at the bottom of the training component to cool it down. However, the problem with this relay protection device is its large size and the vertically mounted, tall training component, which significantly obstructs the view. Since relay protection training is typically conducted in a classroom environment, this obstructed view and the inability to store the device when not in use further complicates the viewing experience, making it difficult to see the teacher's podium and disrupting daily learning.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6This utility model discloses a relay protection training cabinet, including a training platform 10 and a second cabinet 20. A relay protection training simulation device is installed inside the second cabinet 20 to simulate various relay wiring circuits. A training panel side 21 is provided on one side of the second cabinet 20, and the training panel side 21 has several indicator lights and connection ports electrically connected to the relay protection training simulation device. A first tabletop 11 is provided on the training platform 10, and a mounting cavity 25 adapted to the second cabinet 20 is provided next to the first tabletop 11. The mounting cavity 25 allows the second cabinet 20 to be horizontally housed within it. A second tabletop 22 is provided on the side of the second cabinet 20 away from the training panel side 21. A flipping mechanism is provided inside the mounting cavity 25 for engaging with one end of the second cabinet 20. The flipping mechanism is used to drive the second cabinet 20 to flip into or out of the mounting cavity 25. In this embodiment, a flip-up second cabinet 20 is provided on the training platform 10, and the relay protection training simulation device is placed inside it. A second tabletop 22 is provided on one side of the second cabinet 20. When the relay protection training simulation device is needed for relay protection training, the second cabinet 20 is flipped by the flipping mechanism so that the second cabinet 20 is upright, and the training panel side 21 on the second cabinet 20 is exposed and faces one side. Trainees can simulate relay wiring circuits through the various indicator lights 23 and connection ports 24 on the training panel side 21, thereby conducting training. At this time, the first tabletop 11 serves as the working table. When training is not needed, the second cabinet 20 can be flipped by the flipping mechanism so that the second cabinet 20 is in a horizontal state and is stored in the mounting cavity 25. At this time, the training panel side 21 on the second cabinet 20 faces the mounting cavity 25, and the second tabletop 22 is in a horizontal state and is flush with the first tabletop 11. The first tabletop 11 and the second tabletop 22 are combined to serve as the working table. The second cabinet 20 of this application can be freely flipped over and stored when not in use, avoiding obstruction of the view and making it more convenient to use. In addition, the second cabinet 20 in the flipped-over storage state can be used as a countertop, improving functionality.
[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The flipping mechanism includes a first hinge shaft 26 located on both sides of the second cabinet 20 and a second hinge shaft 27 located beside the first hinge shaft 26. The first hinge shaft 26 is hinged to the inner wall of the mounting cavity 25. The mounting cavity 25 also includes a vertically arranged lifting mechanism. The lifting mechanism cooperates with the second hinge shaft 27 to drive the second hinge shaft 27 to move up and down. The lifting mechanism includes a vertically arranged lifting driver 28 and a lifting block 281 on the lifting driver 28. A transverse groove 282 is horizontally opened on the lifting block 281. The second hinge shaft 27 is movably disposed within the transverse groove 282. The mounting cavity 25 has a vertically arranged section that cooperates with the first hinge shaft 26. The vertical groove 251 contains a first hinge shaft 26 movably disposed within it. The vertical groove 251 includes a narrow section 2511 and a circular groove 2512 at the top of the narrow section 2511. The diameter of the circular groove 2512 is larger than the width of the narrow section 2511. The first hinge shaft 26 includes a narrow side 261 adapted to the narrow section 2511 and a wide side 262 adapted to the circular groove 2512. The narrow side 261 is vertically slidably engaged with the narrow section 2511, and the wide side 262 is rotatably engaged with the circular groove 2512. When the narrow side 261 is engaged with the narrow section 2511, the training panel side 21 of the second cabinet 20 faces the first tabletop 11.In this embodiment, when the lifting driver 28 drives the second cabinet 20 to flip and rise, it can first drive the second cabinet 20 to move upward and rise to a certain height before flipping it. This avoids the second cabinet 20 flipping too early and causing it to collide with the inner wall of the mounting cavity 25, making the lifting process more stable. One lifting driver 28 meets two driving needs, and its structure is simple and reasonable. In use, when the second cabinet 20 is not flipped and raised, the second hinge shaft 27 is in the narrow groove section 2511 through the narrow side 261. At this time, under the limiting effect of the narrow groove section 2511, the second hinge shaft 27 cannot flip. When the lifting driver 28 drives the second cabinet 20 to rise, the cooperation between the narrow side 261 and the narrow groove section 2511 can ensure that the second cabinet 20 rises in a horizontal state until the second hinge shaft 27 rises into the circular groove 2512. At this time, the second hinge shaft 27 can freely flip within the circular groove 2512. The lowering block 281 continues to drive the second hinge shaft 27 to rise, so that the second hinge shaft 27 rotates around the first hinge shaft 26. During the rotation, the second hinge shaft 27 adapts to adjust its position within the horizontal groove 282 until the second cabinet 20 rotates to a vertical state, exposing the training panel side 21, which can be used for relay protection training. When the second cabinet 20 needs to be rotated and stored, the second hinge shaft 27 remains rotating within the circular groove 2512 during the initial descent of the lifting drive 28 until the second cabinet 20 rotates to a horizontal state. At this time, the narrow side 261 of the second hinge shaft 27 corresponds to the narrow groove section 2511. When the lifting drive 28 continues to descend, the narrow side 261 slides into the narrow groove section 2511, and the second cabinet 20 can maintain a horizontal state and continue to descend. This application can restrict the movement path of the second cabinet 20 by cooperating with the second hinge shaft 27, thereby improving stability. Example 2
[0028] See Figure 1 , Figure 4 The lifting block 281 is also provided with a limiting block 283 for cooperating with the training panel side 21 of the second cabinet 20. When the training panel side 21 is engaged with the limiting block 283, the training panel side 21 is facing the mounting cavity 25, and the second table surface 22 is in a horizontal state. The limiting block 283 is used to limit the lateral state of the second cabinet 20, prevent it from overturning, and improve stability.
[0029] Specifically, the center of gravity of the second cabinet 20 is located on the side of the second cabinet 20 away from the first hinge axis 26 and the second hinge axis 27.
[0030] See Figure 6 The mounting cavity 25 has vertically arranged protective side plates 29 on the three sides except for the side with the first platform 11. These are used for protection.
[0031] See Figure 7The upper opening of the mounting cavity 25 is provided with a cover plate 30 for detachable connection. When the cover plate 30 is engaged with the mounting cavity 25, the upper surface of the cover plate 30 is flush with the first tabletop 11. The cover plate 30 can be used to cover the mounting cavity 25 when the second cabinet 20 is flipped up to prevent foreign objects from falling into the mounting cavity 25. The cover plate 30 can be stored away when not in use.
[0032] The working process of this utility model:
[0033] In operation, when a relay protection training simulation device is needed for relay protection training, the second cabinet 20 is flipped by a flipping mechanism to stand upright. The training panel side 21 on the second cabinet 20 is exposed and faces one side. Trainees can simulate relay wiring through the indicator lights 23 and connection ports 24 on the training panel side 21, thereby conducting training. At this time, the first table 11 serves as the working table. When training is not required, the second cabinet 20 can be flipped by the flipping mechanism to be in a horizontal state. At this time, the training panel side 21 on the second cabinet 20 faces the first table 11, and the second table 22 is in a horizontal state and is flush with the first table 11. The first table 11 and the second table 22 are combined to form the working table.
[0034] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The internal components of the electric slide rail, cylinder, welding machine, electric telescopic rod and controller all adopt conventional models in the existing technology, and their internal structure belongs to the existing technology structure.
