[0002] High-voltage switchgear is a key device in power systems used to control, protect, and isolate high-voltage electrical equipment, and is widely used in power plants, substations, and industrial distribution systems. "One-button sequential control" is a technology that automates and intelligently operates switchgear through preset control logic. It transforms traditional manual operation processes into automated ones through programmed control modules, improving operational efficiency and safety. This technology is widely used in high-voltage switchgear for remote operation, status monitoring, and fault diagnosis. One-button sequential control high-voltage switchgear typically contains a distribution mechanism for controlling the distribution and switching of power systems. When the distribution mechanism is in normal operating condition, accidentally opening the cabinet door can pose a safety risk. Traditional cabinet doors are controlled by independent locking devices; when the one-button sequential control high-voltage switchgear is in remote control mode, on-site personnel may not be aware of this, and opening the door presents a significant safety risk. Utility Model Content

[0004] To achieve the objectives of this utility model, the following technical solution is adopted:
[0005] A one-button sequential control high-voltage switchgear includes a main body and a cabinet door pivotally connected to the main body. The main body contains a locking mechanism, which includes a turntable, a linkage component, and a locking component. The linkage component is located on one side of the turntable. The locking component is connected to the linkage component via a linkage element. The locking component is mounted on the main body and corresponds to the latch of the cabinet door. The locking component includes a mounting base and a rotating arm pivotally mounted on the mounting base. The rotating arm is connected to the linkage element and includes a slot that corresponds to the shaft of the latch. When the linkage component and the turntable are misaligned, the shaft is in the slot, and the cabinet door is locked; when the linkage component and the turntable are aligned, the cabinet door is released.
[0006] In some embodiments, the turntable is provided with a groove on its periphery, and the linkage component includes a locking block, which is correspondingly arranged with the groove and connected to the linkage component.
[0007] In some embodiments, the linkage component is provided with an elastic element, which is sleeved on the rod of the locking block. The rod is slidably disposed on the base, and the elastic element presses against the base.
[0008] In some embodiments, the mounting base has a guide groove, which is correspondingly arranged with the shaft, and the rotation path of the rotating arm intersects with the guide groove.
[0009] In some embodiments, the mounting base is provided with a support base, and the linkage passes through the support base and is connected to the rotating arm.
[0010] In some embodiments, the card slot has a first arm and a second arm respectively disposed opposite to each other, and the length of the first arm is greater than that of the second arm.
[0011] In some embodiments, when the shaft is located in the slot, the first arm and the second arm are perpendicular to the guide groove.
[0012] In some embodiments, the first arm is provided with a first hook, and the second arm is provided with a second hook, with the first and second hooks bent toward the slot.
[0013] In some embodiments, the rotating arm is connected to the mounting base via a rotating shaft, the linkage is fixed to the fixed base at the end of the rotating arm, and the rotating shaft is disposed between the slot and the fixed base.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] like Figures 1 to 8 As shown in the figure, this embodiment provides a one-button sequential control high-voltage switchgear, including a main body 1 and a cabinet door 2 pivotally connected to the main body 1. The main body 1 is equipped with a locking mechanism 100, enabling the cabinet door 2 to be linked with the power distribution mechanism 200, thereby ensuring personnel safety when opening the cabinet door 2. The locking mechanism 100 includes a turntable 3, a linkage component 4, and a locking component 5. The turntable 3 is gear-shaped and can rotate via a rotating shaft 31. The turntable 3 can be driven by a motor. An electrical control terminal 32 is provided on the turntable 3 for electrical connection with the power distribution mechanism. The power distribution mechanism can extend above the electrical control terminal 32, aligning the contacts with the electrical control terminal. Rotation of the turntable 3 moves the position of the electrical control terminal 32, thereby connecting or disconnecting it from the power distribution mechanism to control the circuit of the power distribution mechanism. Of course, those skilled in the art can also use other devices to control the on / off state of the power distribution mechanism, as long as they can be integrated into the turntable 3 for control. Linkage component 4 is located on one side of turntable 3. Locking component 5 is connected to linkage component 4 via linkage element 6, enabling linkage between linkage component 4 and locking component 5. Linkage element 6 can be a rope with low or no elasticity. Locking component 5 is located on main body 1 and corresponds to latch 21 of cabinet door 2. By connecting or disconnecting from latch 21, cabinet door 2 is controlled. Locking component 5 includes mounting base 51 and rotating arm 52 pivotally mounted on mounting base 51. Rotating arm 52 is connected to linkage element 6. Rotating arm 52 includes slot 521, which corresponds to shaft 211 of latch 21, allowing shaft 211 to engage or disengage from slot 521. When linkage component 4 is misaligned with turntable 3, shaft 211 is located in slot 521, and cabinet door 2 is locked; when linkage component 4 is aligned with turntable 3, cabinet door is released.
[0031] In the above technical solution, when the linkage component 4 is misaligned with the turntable 3, the turntable 3 rotates to the power distribution mechanism's conducting state, and the shaft 211 cannot disengage from the slot 521, preventing the cabinet door from opening and thus avoiding the safety risk of accidentally opening the cabinet door. When the linkage component 4 corresponds to the turntable 3, the turntable 3 rotates to the power distribution mechanism's disconnected state, at which point the cabinet door can be opened or closed, and the safety risk to the operator is relatively small.
[0032] Specifically, the turntable 3 has a groove 33 on its circumference, and the linkage component 4 includes a locking block 41, which is correspondingly arranged with the groove 33 and connected to the linkage member 6. The linkage member 6 enables the locking block 41 to be linked with the rotating arm 52. The linkage component 4 includes an elastic member 42, which is sleeved on the rod 411 of the locking block 41. The rod 411 is slidably arranged on the base 43, and the elastic member 42 presses against the base 43. In this embodiment, the elastic member 42 is a spring. When the turntable 3 rotates to the point where the groove 33 corresponds to the locking block 41, the rotating arm 52 rotates when the cabinet door is opened, the linkage 6 loosens, and the locking block 41 is locked into the groove 33 under the action of elastic force. As the rotating arm 52 rotates, the shaft 211 can be disengaged from the slot 521, allowing the cabinet door to open. When the turntable 3 rotates to the point where the groove 33 and the locking block 41 are misaligned, the locking block 41 is pressed against the circumference of the turntable, and the elastic element cannot make the locking block 41 continue to move forward, so the shaft 211 cannot be disengaged from the slot 521.
[0033] Furthermore, the mounting base 51 has a guide groove 511, which corresponds to the shaft 211. The rotation path of the rotating arm 52 intersects with the guide groove 511, providing guidance for the movement of the shaft 211 and ensuring that the slot 521 can accurately engage or disengage with the shaft 211 when the rotating arm 52 rotates. The mounting base 51 is provided with a support base 53, and the linkage 6 passes through the support base 53 and connects to the rotating arm 52, preventing the linkage 6 from getting stuck in the slot when the rotating arm 52 rotates. The rotating arm 52 is connected to the mounting base 51 via a rotating shaft 54, and the linkage 6 is fixed to the fixed seat 55 at the end of the rotating arm 52. The rotating shaft 54 is located between the slot 521 and the fixed seat 55. The slot 521 has a first arm 522 and a second arm 523 respectively arranged opposite to each other. The length of the first arm 522 is greater than that of the second arm 523. When the shaft 211 is in the slot 521, the first arm 522 and the second arm 523 are perpendicular to the guide groove 511. The first arm 522 is provided with a first hook 5221, and the second arm 523 is provided with a second hook 5231. The first and second hooks are bent towards the slot 521. When the cabinet door 2 is closed, the shaft 211 pushes the first arm 522, causing the rotating arm 52 to rotate. When the linkage assembly 4 is misaligned with the turntable 3, when the cabinet door 2 is opened, the rotating arm 52 loses its rotational power. When the shaft 211 is pulled, the shaft 211 gets stuck at the second hook 5231 and cannot be disengaged. The latch 21 includes a fitting 212, which has a fitting groove 213. A shaft 211 is disposed in the fitting groove 213 and its two ends are connected to the side wall of the fitting groove 213. The shaft 211 is vertically disposed so that the shaft 211 can move perpendicular to the guide groove 511.
[0034] This embodiment uses a linkage component to create a linkage between the locking component and the linkage component, so that the cabinet door cannot be opened when the power distribution mechanism is in operation, ensuring personnel safety; in addition, the mutual cooperation between the shaft and the slot can simplify the structure and improve the reliability of shaft locking and releasing.
[0035] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
