[0002] High-voltage switchgear refers to the switchgear used for power generation, transmission, distribution, power conversion and consumption in the power system. It plays the role of switching on and off, controlling or protecting. Generally, a locking device is installed in the cabinet, including mechanical locking, program locking, electrical interlocking, etc., to prevent maintenance personnel from opening the cabinet under power and causing electric shock.

[0003] Chinese patent authorization announcement number CN216489178U discloses an anti-mistaken locking device for a distribution network switch cabinet, including an anti-mistaken locking device body, the anti-mistaken locking device body is arranged on the switch cabinet, a partition is arranged in the switch cabinet, and the interior of the switch cabinet is divided into two left and right cavities by the partition, and electrical components are arranged in the left and right cavities. Through the anti-mistaken locking device that can directly act on the movable door of the switch cabinet, the first movable door, the second movable door and the partition are locked when the power is not cut off to prevent maintenance or other personnel from opening the switch cabinet, thereby ensuring the use of the anti-mistaken locking device. The above-mentioned prior art solution has the following shortcomings: the device uses the action of permanent magnets and electromagnetic coils to realize the power-on closure of the left and right movable doors to prevent accidental opening. However, since the structure is mainly arranged at the connection and closure of the two movable doors, when the cabinet body is opened, the locking structure will not lock the opened movable doors, so that during the maintenance process of the staff, the movable doors are movable, and then in the outdoor working state, the movable doors are easy to shake under the operation of wind and other operations, so that they are easy to hit the maintenance personnel. Therefore, there is room for improvement. Utility Model Content

[0022] See also Figure 1-Figure 4 The utility model provides an embodiment: an anti-mislocking structure of a high-voltage switch cabinet, which is arranged on a high-voltage switch cabinet body 1, a cabinet door 2 is hinged on one side of the high-voltage switch cabinet body 1, and a mislocking component 5 is arranged on the inner side of the cabinet door 2 close to the end of the high-voltage switch cabinet body 1;

[0023] The mis-locking assembly 5 comprises a fixed shaft 501 installed on the side of the cabinet door 2 close to the slide slot 6, and a flip plate 502 is sleeved on the outside of the fixed shaft 501, a gusset plate 503 is installed on the bottom end of the flip plate 502 away from the fixed shaft 501, and a magnet 504 is installed on the inner side of the gusset plate 503;

[0024] The flip plate 502 is rotatably connected to the fixed shaft 501, the distance between the fixed shaft 501 and the slide slot 6 is greater than the width of the slide slot 6, and the length of the flip plate 502 is greater than the distance between the fixed shaft 501 and the slide slot 6;

[0025] A metal block 12 is embedded inside the block 9 on one side of the magnet 504. When the flip plate 502 is placed on top of the block 9, the magnet 504 and the metal block 12 attract each other.

[0026] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when in use, the flip plate 502 and the buckle plate 503 are used to hook the bridge block 9, and the baffle plate 10 and the elastic block 11 are used to fix the flip plate 502 horizontally, thereby preventing the cabinet door 2 from flipping over to close the high-voltage switch cabinet body 1, thereby preventing the maintenance personnel from being hit by the cabinet door 2 when inspecting the interior of the high-voltage switch cabinet body 1, so as to achieve the effect of mis-locking;

[0027] A slide groove 6 is provided on one side of the high-voltage switch cabinet body 1 close to the cabinet door 2, and a slide plate 7 is slidably installed inside the slide groove 6;

[0028] The slide plate 7 and the slide groove 6 form a front-to-rear sliding structure. When the slide plate 7 slides to the outermost side, the block 9 and the baffle 10 extend to the outside of the slide groove 6.

[0029] Specifically, Figure 1 , Figure 2As shown, when in use, the spring 8 is used to facilitate the sliding plate 7 to slide forward and backward, so that when the cabinet door 2 closes the high-voltage switch cabinet body 1, the block 9 and the baffle 10 will not hinder the closing tightness of the cabinet door 2;

[0030] A block 9 is installed at the bottom end of the outer side of the slide plate 7, and a baffle 10 is installed on the outer side of the block 9;

[0031] The baffle 10 and the building block 9 are an integrated structure, and the cross section formed by the two is L-shaped when viewed from above;

[0032] The top view cross section of the baffle 10 is an isosceles trapezoid, and one side of the baffle 10 is inclined to guide the flipping direction of the cabinet door 2;

[0033] An elastic block 11 is installed at the top of the baffle 10 near the side of the slide plate 7, and a spring 8 is evenly installed on the side of the slide plate 7 away from the step block 9, and one end of the spring 8 is connected to the inner wall of the slide groove 6. When the cabinet door 2 is opened, the locking mechanism is connected to the step block 9 to fix the cabinet door 2. A fixing box 4 is installed on the side of the high-voltage switch cabinet body 1 away from the cabinet door 2, and a lock hole 13 is opened on the outside of the fixing box 4, and an electromagnet 14 is arranged inside the lock hole 13. A fixed lock 3 is installed on the outside of the cabinet door 2 away from the high-voltage switch cabinet body 1, and the position of the fixed lock 3 corresponds to the position of the lock hole 13;

[0034] Specifically, Figure 1 , Figure 2 As shown, the structure of the baffle plate 10 is utilized during use so that when the cabinet door 2 is flipped and closed, the baffle plate 10 can be pushed to automatically move toward the inside of the slide groove 6 .

[0035] Working principle: When the utility model is used, firstly, the high-voltage switch cabinet body 1 is energized so as to energize the electromagnet 14. When the cabinet door 2 is closed to the high-voltage switch cabinet body 1, the fixed lock 3 is inserted into the lock hole 13, so that the electromagnet 14 attracts the fixed lock 3, thereby fixing the cabinet door 2 to prevent maintenance when the high-voltage switch cabinet body 1 is energized.

[0036] Secondly, when the power is cut off inside the high-voltage switch cabinet body 1, the cabinet door 2 can be opened. When the cabinet door 2 is opened to be parallel to the high-voltage switch cabinet body 1, the flip plate 502 is flipped counterclockwise so that the flip plate 502 touches the elastic block 11 first, and a certain force is applied to make the flip plate 502 rest on the top of the stepping block 9, so that one side of the magnet 504 attracts the outer side of the stepping block 9 to fix the flip plate 502, thereby using the function of the flip plate 502 to fix the cabinet door 2 to prevent the cabinet door 2 from automatically flipping under the action of wind.

[0037] Finally, during the opening process of the cabinet door 2, as the cabinet door 2 gradually moves away from the high-voltage switch cabinet body 1, the slide plate 7 moves outward along the slide groove 6 under the elastic return action of the spring 8, so that the step block 9 and the baffle 10 extend out of the slide groove 6 to facilitate the flip plate 502 to be placed on the step block 9. When the cabinet door 2 closes the high-voltage switch cabinet body 1, the inner wall of the cabinet door 2 contacts the inclined surface of the baffle 10, so that the cabinet door 2 pushes the baffle 10 to move inward, so that the baffle 10 moves to the inside of the slide groove 6.
