Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage power equipment accessories, in particular to a modular transmission adjustment mechanism for a high-voltage disconnector. Background Art

[0002] High-voltage disconnectors are crucial control devices in the electrical systems of power generation and substations, used in conjunction with high-voltage circuit breakers. Their purpose is to connect, disconnect, or switch circuits when voltage is present and load is unloaded. Their primary functions include ensuring the safety of high-voltage electrical equipment and devices during maintenance and repair, isolating voltage, and preventing them from disconnecting or switching on load current or interrupting short-circuit current. The connection and disconnection process generates powerful arcs, which can severely damage the connected terminals. Therefore, the connection and disconnection speeds must be as high as possible. However, current operation can only be adjusted by varying the rotational speed, which is not only cumbersome but also unstable. Furthermore, the transmission mechanism of high-voltage disconnectors is often fixed, requiring high equipment coordination during assembly and disassembly, resulting in high maintenance costs. Summary of the Invention

At the same time, the transmission mechanism of the high-voltage disconnector is mostly fixed installation, and the loading and unloading requires a relatively high degree of equipment coordination, resulting in a relatively high cost of subsequent maintenance.

[0009] The central lateral control arm and the lateral extrusion arm are connected via a lateral movable bracket.

[0010] The lateral drive box body is movably mounted on the right side wall of the third transmission box body through a lateral assembly tube, and the lateral drive box body is movably equipped with an internal central drive gear, a main drive gear that cooperates with the lateral drive shaft of the drive motor, a secondary drive gear and a lateral drive tooth head axially fixed to the internal central drive gear.

[0024] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] Figure 1 、 Figure 2 and Figure 3 The modular transmission adjustment mechanism for a high-voltage disconnector shown in the figure includes a bottom assembly frame 1, a drive motor 2, a first insulating component 3, a second insulating component 4 and a third insulating component 5 installed on the bottom assembly frame 1. A modular lateral transmission component for installing the drive motor 2 is bolted to the outer surface of the front end of the bottom assembly frame 1. A central lateral control arm 6 controlled by the modular lateral transmission component is installed at the assembly end of the second insulating component 4 inside the bottom assembly frame 1. An overhead flip conductive arm 7 is bolted to the top of the second insulating component 4.

[0026] The drive motor 2 is a prior art and is used to control the operation of the modular lateral transmission assembly.

[0027] In order to adjust the lateral rollover, a lateral rollover control notch 8 is opened on the side wall of the bottom assembly frame 1 at the position of the central lateral control arm 6.

[0028] In order to cooperate with the lateral assembly, a side bending frame 9 is welded and fixed to the front side wall of the bottom assembly frame 1, and the modular lateral transmission assembly is fixed to the side bending frame 9 and fixedly assembled inside the side bending frame 9 by bolts.

[0029] In order to facilitate loading and unloading, the modular lateral transmission assembly includes a first transmission box body 10, a second transmission box body 11, and a third transmission box body 12 bolted to the side bending frame 9, a built-in lateral control assembly installed inside the first transmission box body 10, the second transmission box body 11, and the third transmission box body 12, and a lateral drive box body 13 movably assembled on the right side surface of the third transmission box body 12.

[0030] The first transmission box body 10, the second transmission box body 11, the third transmission box body 12 and the lateral drive box body 13 are fixedly assembled by bolts. The built-in lateral control components inside the first transmission box body 10, the second transmission box body 11 and the third transmission box body 12 have the same structure.

[0031] In order to cooperate with the transmission, the built-in lateral control component includes a transverse transmission rod 14, a side linkage tooth head 15 axially fixed on one side of the transverse transmission rod 14, a side linkage sleeve 16 axially fixed on the other side of the transverse transmission rod 14, a first drive gear 17 axially sleeved on the outside of the transverse transmission rod 14, a second drive gear 18, a lateral transmission rod 19 axially fixed on the second drive gear 18, a first threaded rod 20 axially installed on the outside of the lateral transmission rod 19, a second threaded rod 21, a first guide tube 22, a second guide tube 23 slidingly sleeved on the outside of the first guide tube 22, a first internally threaded drive tube 24 axially fixed on the inner side of the second guide tube 23, a second internally threaded drive tube 25 axially fixed on the inner side of the second guide tube 23 and a lateral extrusion arm 26 movably assembled on the end of the second guide tube 23 away from the first guide tube 22.

[0032] The adjacent transverse transmission rods are inserted into the side linkage sleeve 16 through the side linkage tooth head 15 for axial transmission, and then the first drive gear 17 and the second drive gear 18 are engaged for transmission. When the transverse transmission rod 14 rotates, the first drive gear 17 and the second drive gear 18 engaged for transmission drive the lateral transmission rod 19 to rotate, and the lateral transmission rod 19 drives the first threaded rod 20, the second threaded rod 21, and the first guide tube 22 to rotate. First, the first threaded rod 20 is threadedly assembled with the first internally threaded drive tube 24, and the second guide tube 23 slides and retracts slowly along the second guide tube 22. When the first threaded rod 20 is separated from the first internally threaded drive tube 24, the second threaded rod 21 is threadedly assembled with the second internally threaded drive tube 25, and the second guide tube 23 slides and retracts quickly along the second guide tube 22.

[0033] The thread density of the first threaded rod 20 is greater than the thread density of the second threaded rod 21 .

[0034] In order to cooperate with the lateral movable assembly, the central lateral control arm 6 and the lateral extrusion arm 26 are connected through a lateral movable bracket.

[0035] The central lateral control arm 6 is squeezed outward by the lateral squeezing arm 26, thereby driving the second insulating component 4 to rotate, and then the second insulating component 4 drives the top flip conductive arm 7 at the top to flip, controlling the connection with the joint at the top of the first insulating component 3, the third insulating component 5 or the top flip conductive arm at the adjacent position.

[0036] In order to cooperate with the lateral drive, the lateral drive box body 13 is movably installed on the right side wall of the third transmission box body 12 through the lateral assembly tube. The lateral drive box body 13 is movably equipped with an internal central drive gear 28, a main drive gear 29 that cooperates with the lateral drive shaft of the drive motor 2, a secondary drive gear 30 and a lateral drive tooth head 300 axially fixed on the internal central drive gear 28.

[0037] The main drive gear 29 and the auxiliary drive gear 30 are both engaged with the internal center drive gear 28 for transmission. The internal center drive gear 28 is inserted into the side linkage sleeve 16 on the right side of the third transmission box body 12 through the side drive gear head 300 and axially transmits power to the transverse transmission rod 14.

[0038] An external mounting sleeve for connecting an external control handle is axially mounted on the outer side of the auxiliary driving gear 30 , and is used to connect an external control handle for manual operation on the outer side.

[0039] In order to adjust the installation position, a strip-shaped bolt fixing opening 31 for assembling the first transmission box body 10 , the second transmission box body 11 and the third transmission box body 12 is opened at the bottom of the side bending frame 9 .

[0040] The first transmission box body 10, the second transmission box body 11, and the third transmission box body 12 are fixed in the side bending frame 9 by screwing the locking bolt inside the strip bolt fixing port 31 into the internal threaded mounting hole at the bottom of the first transmission box body 10, the second transmission box body 11, and the third transmission box body 12.

[0041] In order to coordinate the internal transmission and wiring without affecting each other and to improve safety and stability, the bottom assembly frame 1 has an integrated central isolation plate 32 inside. The bottom assembly frame 1 is divided by the central isolation plate 32 into a transmission chamber for accommodating the lateral transmission rod 19, the second guide tube 23 and the lateral extrusion arm 26, and a wiring chamber for placing the wires.

[0042] The modular transmission adjustment mechanism for a high-voltage disconnector of the present invention adopts a modular structural design and can be independently disassembled and replaced as needed, greatly reducing the difficulty and cost of early assembly and later disassembly; the internal threaded drive tube is driven by threaded rods with different thread densities, and the speed of the second guide tube 23 and the lateral extrusion arm 26 can be adjusted at different positions, thereby ensuring that the speed of the control end is consistent while improving the operation speed during connection and disconnection, and the operation stability is higher, and the safety and durability are better; through the modular structural design, the scope and scenarios of the entire transmission adjustment mechanism can be improved; the lateral drive box body 13 is installed on the right side of the third transmission box body 12, and the installation position of the drive motor 2 and the hand control device can be adjusted, making it adaptable to more diverse assembly methods; by adopting a built-in hidden layout design, the durability of the entire adjustment mechanism is greatly improved.

The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
