[0032] The present invention will be further described below: A spring energy storage device for preventing misoperation of an outdoor high-voltage combined electrical appliance, see [link to relevant documentation]. Figures 1 to 5 It includes an anti-misoperation spring energy storage device 8, a disconnector switch linkage mechanism 7, and a circuit breaker linkage mechanism 9.

[0033] The disconnector linkage mechanism 7 consists of a main shaft 71, a main shaft crank arm 72, a disconnector insulating pull rod 74, and a disconnector crank arm 73. The main shaft crank arm 72 and the disconnector crank arm 73 are both fixed on the main shaft 71. The disconnector crank arm 73 is connected to the disconnector 2 through the disconnector insulating pull rod 74.

[0034] The anti-misoperation spring energy storage device 8 consists of an energy storage shaft 81, an energy storage spring 82, and an energy storage transmission link 83. The energy storage transmission link 83 consists of a transmission crank arm 831, a push rod 832, a rotating rod 833, and an energy storage crank arm 834 connected in sequence. The transmission crank arm 831 is fixed on the main shaft 71, and the energy storage crank arm 834 is fixed on the energy storage shaft 81. The main shaft 71 rotates synchronously with the energy storage shaft 81 through the energy storage transmission link 83, so that the energy storage spring 82 stores energy. The anti-misoperation spring energy storage device 8 also has an energy storage limit mechanism 85 to prevent the energy storage shaft 81 from rotating erroneously after the energy storage spring 82 stores energy, and a tripping trigger mechanism for disengaging the energy storage limit mechanism 85.

[0035] The circuit breaker linkage mechanism 9 consists of a second crank arm 91 of the energy storage shaft and a second linkage transmission mechanism 92. The second crank arm 91 of the energy storage shaft is fixed on the energy storage shaft 81 and drives the circuit breaker insulating pull rod 6 of the circuit breaker 3 to move up and down through the second linkage transmission mechanism 92. This utility model's anti-misoperation spring energy storage device 8 achieves integrated operation control of the isolating switch 2 and the circuit breaker 3. The closing and opening of the isolating switch 2 and the circuit breaker 3 can be achieved through a single electric operating mechanism, meeting the requirements of high-voltage power-on and power-off operation sequences. It also has a mechanical interlocking function to prevent misoperation. This integrated switch structure ensures robustness and mechanical reliability, while eliminating connecting wires between equipment during decentralized installation, reducing contact resistance by 60%.

[0036] The energy storage limiting mechanism 85 consists of a limiting rod, an initial limiting hook, and an energy storage limiting hook. The limiting rod is mounted on the push rod 832 and is located near the rotational connection between the push rod 832 and the rotating rod 833. The initial limiting hook limits the position of the push rod 832 before energy storage via the limiting rod, and the energy storage limiting hook limits the position of the push rod 832 after energy storage. Both the initial limiting hook and the energy storage limiting hook are fixed to the frame 1 to be installed. During the process of the main shaft 71 driving the energy storage shaft 81 to rotate and store energy, the push rod 832 pushes towards the energy storage shaft 81, and the limiting rod is pushed from the initial limiting hook to the energy storage limiting hook for engagement and limiting. Before closing and storing energy, the limit rod is located at the initial limit hook to prevent accidental operation that could cause the main shaft 71 to rotate clockwise. When the main shaft 71 rotates counterclockwise to store energy, the energy storage transmission link 83 is pushed towards the energy storage shaft 81, simultaneously driving the energy storage shaft 81 to rotate counterclockwise for energy storage. When the energy storage shaft 81 is pushed to the set position, energy storage is completed. At this time, the limit rod is precisely engaged at the energy storage limit hook, keeping the main shaft 71 and the energy storage spring 82 in a continuous energy storage state. If the circuit breaker 3 or the energy storage spring 82 is misoperated, the energy storage spring 82 will rotate clockwise. Since the main shaft 71 is not rotating, the push rod 832 will remain stationary, and the rotating rod 833 can only rotate downwards around the push rod 832. At this time, the limit post located in the energy storage limit hook cannot be disengaged, thus effectively preventing accidental operation. The limiting post only rotates slightly counterclockwise when the main shaft 71 rotates counterclockwise, causing the energy storage spring 82 to release energy and rotate the energy storage shaft 81 clockwise. This causes the rotating connection between the push rod 832 and the rotating rod 833 to arch upwards, allowing the limiting rod to disengage from the energy storage limiting hook and achieve release. Then, the energy storage spring 82 releases its elastic force, driving the energy storage shaft 81 to rotate clockwise. The rotating rod 833 then pushes the push rod 832 in the opposite direction, causing the main shaft 71 to rotate clockwise, thus performing the opening operation of the isolating switch 2. The working rotation direction of the energy storage shaft 81 and the main shaft 71 in this invention is... Figure 5 Based on.

[0037] To achieve the disengagement of the limit rod from the energy storage limit hook, a circuit breaker triggering mechanism was designed. This mechanism comprises a first crank arm 851 of the energy storage shaft, a limit movable rotating arm 852, a rotating shaft 853, a trigger rod 854, a trigger hook rod 855, and a first connecting rod 856. The first crank arm 851 is fixed to the energy storage shaft 81 and is rotatably connected to the rotating shaft 853 via the limit movable rotating arm 852. The limit movable rotating arm 852 is a movable mechanism formed by hinged two arms, with a maximum rotation angle of 180°. The two arms consist of arm A and arm B, where arm A is groove-shaped and arm B... The end of the arm is located in a groove and is rotatably hinged to the support arm A. When the support arm B rotates, due to the limiting block at the end of the support arm A, the support arm B can only rotate a maximum of 180°. At this time, the energy storage spring is in the fully charged state. The trigger rod 854 is fixed in the middle of the limiting movable rotating arm 852. The middle of the trigger hook rod 855 is rotatably connected to the rotating shaft 853. The right end of the trigger hook rod 855 is connected to the main shaft 71 through the first connecting rod 856. The left end of the trigger hook rod 855 is located above the trigger rod 854. The rotation of the trigger hook rod 855 moves the trigger rod 854 to rotate the energy storage shaft 81. The specific method is as follows: through the design of its length, when the energy storage spring 82 is fully charged and locked by the limiting rod and the energy storage limiting hook, the limiting movable rotating arm 852 is in a straight line state. When driven by the electric operating mechanism 5... A slight counterclockwise rotation of the main shaft 71 disengages the limit rod from the energy storage limit hook. The disengagement principle is as follows: When the main shaft 71 rotates slightly clockwise, it drives the first connecting rod 856 to pull the right end of the trigger hook rod 855, causing the trigger hook rod 855 to rotate. The left end of the trigger hook rod 855 presses down on the trigger rod 854, breaking the linear balance of the limit movable arm 852. At this time, the energy storage spring 82 begins to release energy, causing the energy storage shaft 81 to rotate clockwise. Simultaneously, due to the rotation of the main shaft 71, the push rod 832 of the energy storage transmission connecting rod 83 also moves forward. At this time, the connection with the rotating rod 833 will slightly arch, realizing the disengagement of the limit post from the energy storage limit hook. After the disengagement is completed, the electric operating mechanism 5 does not work, and the energy storage spring 82 drives the energy storage shaft 81 to rotate clockwise to perform the disconnection operation of the isolating switch 2 and the circuit breaker 3.

[0038] During the energy storage and release process, the energy storage spring 82, in addition to opening and closing the disconnecting switch 2, also synchronously links the circuit breaker 3 through the circuit breaker linkage mechanism 9. The second link 921 transmission mechanism consists of the second link 921, the pull rod A922, the positioning rod A923, and the push rod A924. The upper end of the pull rod A922 is rotatably connected to the second link 921, and the lower end is rotatably connected to the middle of the positioning rod A923. The end of the second link 921 away from the pull rod A922 is rotatably connected to the second crank arm 91 of the energy storage shaft. The lower end of the push rod A924 is rotatably connected to the middle of the pull rod A922. The upper end of the push rod A924 is rotatably connected to the lower end of the circuit breaker insulating pull rod 6 through the guide shaft 925. The frame 1 to be installed is vertically provided with a guide groove 926 to facilitate the up and down sliding of the guide shaft 925. When the energy storage spring 82 stores energy, the energy storage shaft 81 rotates counterclockwise, pushing the second connecting rod 921 and the pull rod A922 through the second crank arm 91 of the energy storage shaft. This causes the guide shaft 925 at the upper end of the push rod A924 to slide upward along the guide groove 926, pushing the circuit breaker insulation pull rod 6 upward to make the circuit breaker 3 conductive. When the energy storage spring 82 releases energy, the energy storage shaft 81 rotates clockwise, pulling the second connecting rod 921 and the pull rod A922 through the second crank arm 91 of the energy storage shaft. This causes the guide shaft 925 at the upper end of the push rod A924 to slide downward along the guide groove 926, pulling the circuit breaker insulation pull rod 6 downward to de-energize the circuit breaker 3.

[0039] In power systems, the operational sequence of circuit breaker 3 and disconnector 2 is crucial. When energizing and closing, disconnector 2 must be closed before energizing circuit breaker 3; similarly, when de-energizing, circuit breaker 3 must be de-energized before closing disconnector 2. This invention utilizes the linkage between the anti-misoperation spring energy storage device 8, the disconnector linkage mechanism 7, and the circuit breaker linkage mechanism 9 to ensure strict adherence to the relevant sequence during energization and de-energization. The specific linkage process is as follows:

[0040] When powered on, the electric operating mechanism 5 is energized, driving the main shaft crank arm 72 to rotate the main shaft 71 counterclockwise. At this time, the disconnecting switch crank arm 73 pushes the disconnecting switch insulating rod 74 to close the disconnecting switch 2. Simultaneously, the energy storage spring 82 stores energy. While the energy storage spring 82 is storing energy, the energy storage shaft 81 rotates counterclockwise, and the second linkage transmission mechanism 92 lifts the circuit breaker insulating rod 6 from bottom to top, completing the energization of the circuit breaker 3. Since the circuit breaker 3 needs to be driven to lift the circuit breaker insulating rod 6 through the anti-misoperation spring energy storage device 8 and the circuit breaker linkage mechanism 9 to complete the energization, while the disconnecting switch 2 is directly driven to close by the electric operating mechanism 5, the closing of the disconnecting switch 2 will precede the energization of the circuit breaker 3.

[0041] When power is cut off, the electric operating mechanism 5 is briefly energized, causing the main shaft 71 and the energy storage shaft 81 to rotate slightly counterclockwise to disengage the limit rod. After the limit rod disengages, the electric operating mechanism 5 is de-energized, the energy storage spring 82 is fully released, and the energy storage shaft 81 rotates clockwise. The energy storage shaft 81 first pulls the second linkage transmission mechanism 92 to pull down the circuit breaker insulation rod 6, thus completing the power cut-off of the circuit breaker 3. Then, through the energy storage transmission linkage 83, the main shaft 71 is pushed to rotate clockwise, lifting the isolating switch insulation rod 74 from bottom to top, thus completing the opening of the isolating switch 2. This process takes longer than the opening time of the circuit breaker 3.

[0042] Furthermore, this utility model also includes a buffer mechanism 93, which consists of a pressure plate 931, a buffer spring 932, a spring rod 934, and a spring seat 933. The spring seat 933 is fixed to the frame 1 to be installed. The buffer spring 932 is located between the pressure plate 931 and the spring seat 933. The upper end of the spring rod 934 is fixed to the pressure plate 931, and the lower end passes through the buffer spring 932 and the spring seat 933, and is rotatably connected to the left end of the positioning rod A923. The right end of the positioning rod A923 is rotatably connected to the frame 1 to be installed. During the energy storage and release process of the energy storage spring 82, the buffer mechanism 93 provides a buffer margin for the circuit breaker linkage mechanism 9. If the buffer mechanism 93 is not required, it is sufficient to fix both ends of the positioning rod A923 to the frame 1.

[0043] Furthermore, to prevent the disconnector switch 2 from opening before the circuit breaker 3 trips during the opening process, the upper end of the disconnector switch insulating rod 74 is rotatably connected to the middle of the disconnector switch 2's switch blade via a rotating shaft. A delay groove 75 is provided at the connection between the disconnector switch insulating rod 74 and the disconnector switch 2. The rotating shaft is located within the delay groove 75 and is slidably connected to it. When the energy storage spring 82 releases energy, it drives the main shaft 71 to rotate clockwise. When the main shaft 71 drives the disconnector switch insulating rod 74 upward through the disconnector switch crank arm 73, it will first slide upward along the delay groove 75. At this time, the disconnector switch 2 will not open. Only after the energy storage spring 82 drives the circuit breaker 3 to complete the de-energization will the disconnector switch insulating rod 74 slide to the top of the delay groove 75 and push the disconnector switch 2's switch blade to open.

[0044] This utility model also includes a frame 1 to be installed. The frame 1 adopts a double-column steel structure frame, arranged in two layers. All mechanisms and switches are fixed on the double-column metal structure, and the integrated switch structure ensures robustness and mechanical reliability. Meanwhile, the integrated layout of the circuit breaker 3 and disconnector 2 occupies less space. The frame 1 houses the disconnector 2, circuit breaker 3, current transformer 4, anti-misoperation spring energy storage device 8, disconnector linkage mechanism 7, and circuit breaker linkage mechanism 9. The circuit breaker 3 and disconnector 2 are designed on the same frame 1, achieving an integrated layout, thus optimizing space and reducing the floor space by more than 40% compared to the traditional separate layout, making the substation layout more flexible. Centralized maintenance is more convenient and effectively improves the efficiency of inspection and maintenance work.

[0045] It also includes an electric operating mechanism 5, a drive crank arm 51, and a transmission rod 52. The electric operating mechanism 5 controls the rotation of the drive crank arm 51 and is connected to the main shaft crank arm 72 via a transmission link. The main shaft 71 is linked with the disconnecting switch linkage mechanism 7 and the circuit breaker linkage mechanism 9 via an anti-misoperation spring energy storage device 8. The disconnecting switch 2 is switched on and off via the disconnecting switch insulating pull rod 74. The circuit breaker 3 is driven to move up and down via the circuit breaker linkage mechanism 9.

[0046] The large umbrella skirt structure at the top of the post insulator of the disconnecting switch 2 can improve the pollution resistance and insulation level of the disconnecting switch 2.

The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, based on the idea of ​​this utility model, there will be changes in the specific implementation and application scope.

Therefore, the content of this specification should not be construed as a limitation of this utility model.
