Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a disconnector reset mechanism. Background Technology

[0002] Disconnecting switches are important switching electrical devices in power systems. Their main functions are to isolate power sources in circuits, perform switching operations, and connect or disconnect circuits with no or low current. However, traditional disconnecting switch reset mechanisms have many inconveniences in actual operation.

[0003] A search revealed an existing patent (publication number: CN222690622U) disclosing a novel drop-out fuse, belonging to the field of drop-out fuses. It includes a high-strength insulator with an upper terminal at its upper end and a lower terminal connected to its lower end. The upper terminal has a connecting buckle, and the lower terminal has a rotating connecting frame. Through this mounting structure, the mounting plate is mounted on a fixed frame via a rotating base, allowing for rotational adjustment as needed, thus improving the overall flexibility of the drop-out fuse. A slot is provided on the rotating base for use with a limiting rod, enabling angle adjustment of the drop-out fuse at specific angles while ensuring stability after adjustment. The hexagonal block at the end of the limiting rod connects to a threaded seat via a threaded groove, ensuring the connection stability of the limiting rod and preventing it from detaching and causing the drop-out fuse to loosen. During the development of this application, the inventors discovered the following problems with the existing technology:

[0004] When resetting existing disconnect switches, operators typically need to use an operating lever to lift the contact blade upwards to the fully reset position. This process not only requires operators to have high operating skills but also consumes a lot of physical strength. Especially in scenarios requiring frequent operation or working at height, it increases the difficulty of operation and safety risks. At the same time, although there are some disconnect switches in the existing technology that improve the flexibility of use by rotating adjustment, there is still room for improvement in terms of the convenience and efficiency of the reset operation.

[0005] Therefore, a disconnector reset mechanism is proposed to address the aforementioned technical problems. Summary of the Invention

[0006] To address the aforementioned issues, this application provides a disconnector reset mechanism.

[0007] This application provides a disconnector switch reset mechanism, which adopts the following technical solution:

[0008] A disconnector reset mechanism includes a high-strength insulator and a fixing ring. The fixing ring is fixed to the outside of the high-strength insulator. A self-locking mounting assembly and an auxiliary reset assembly for mounting the high-strength insulator are fixed to the outside of the fixing ring. A connecting plate and a hinge seat are fixedly mounted on the outside of the high-strength insulator. The connecting plate is located above the hinge seat. A contact blade is fixedly mounted on the hinge seat. An operating ring is fixed to the outside of the contact blade. A compression spring is fixedly mounted at the bottom of the connecting plate. A stationary contact piece is fixedly mounted on the other side of the compression spring. The top of the contact blade engages with the stationary contact piece. Waterproof plates are fixed on both sides of the connecting plate. The stationary contact piece is located between the two waterproof plates.

[0009] Preferably, the self-locking mounting assembly includes a mounting bracket, a worm gear, and a mounting shaft for mounting the high-strength insulator. The mounting bracket is fixed to the outside of the fixing ring. One end of the worm gear is rotatably mounted on the inner wall of the top of the mounting bracket. Both ends of the mounting shaft are rotatably mounted inside the mounting bracket. A mounting plate and a turbine are fixed to the outside of the mounting shaft. The turbine and the worm gear mesh with each other.

[0010] By adopting the above technical solution, the worm gear rotates, driving the turbine and mounting shaft to rotate synchronously, enabling precise angle adjustment of the mounting plate. This allows for adjustment of the installation angle of the high-strength insulator, ensuring that the fuse maintains optimal working condition under different installation environments. This mechanical linkage structure not only improves the stability of component installation but also effectively prevents the high-strength insulator from loosening due to vibration during long-term operation through the self-locking characteristics of the worm gear.

[0011] Preferably, the mounting plate is provided with mounting holes, the other end of the worm gear passes through the mounting frame and is fixed with a knob, and the bottom of the mounting frame is provided with multiple insertion holes, which are distributed in a circumferential array.

[0012] By adopting the above technical solution, the design of the mounting holes facilitates the fixing of the entire mechanism to the external support structure with fasteners such as bolts, enhancing the flexibility and versatility of installation. The knob allows the operator to manually rotate the worm gear to adjust the angle of the mounting plate, while the multiple circumferentially distributed insertion holes provide a variety of fixing position options, allowing the operator to insert the insertion rod into different insertion holes according to actual needs, realizing multi-angle positioning of the mounting plate, and further improving the adaptability and stability of equipment installation.

[0013] Preferably, the bottom of the knob is provided with a fixing groove, a first reset spring is fixedly installed inside the fixing groove, and a fixing block is fixed to the other end of the first reset spring, the fixing block being slidably engaged inside the fixing groove.

[0014] By adopting the above technical solution, the fixing block can move up and down inside the fixing groove under the action of external force, so as to stretch the reset spring and facilitate the subsequent reset of the fixing block.

[0015] Preferably, a connecting frame is fixed to the bottom of the fixing block, and a plug rod is inserted into one of the plug holes, with the other end of the plug rod fixed to the top of the connecting frame.

[0016] By adopting the above technical solution, the insertion rod is mechanically locked inside the insertion hole, forming a double insurance with the self-locking structure of the worm gear. When the operator rotates the knob to adjust to the target angle, the insertion rod is automatically inserted into the corresponding insertion hole under the elastic force of the return spring. This not only prevents the worm gear from rotating unexpectedly due to vibration, but also enhances the overall shock resistance through the mechanical insertion structure.

[0017] Preferably, the auxiliary reset assembly includes a side plate, a movable plate, a rope, and an insulating sleeve. The side plate is fixed to the outside of the fixed ring. The top and bottom of the side plate are provided with sliding grooves. The movable plate is slidably engaged in the sliding grooves. One side of the rope is fixedly connected to the top of the movable plate. The insulating sleeve is fixedly connected to the outside of the contact blade. The other end of the rope is fixed to one side of the insulating sleeve.

[0018] By adopting the above technical solution, when the contact blade separates or opens, its outer insulating sleeve will fall with the contact blade. At this time, the rope is tightened due to the downward movement of the insulating sleeve, which drives the moving plate to slide up and down in the groove. The movement of the moving plate provides the necessary displacement basis for the subsequent reset action, so that the fuse will not be directly suspended in the air after it is disconnected, but will create conditions for the subsequent reset operation through the linkage of the auxiliary reset component.

[0019] Preferably, a second return spring is fixedly connected between the movable plate and the slide groove, a rotating shaft is rotatably installed inside the slide groove, a fixed pulley is fixed on the outside of the rotating shaft, and the rope is wound around the outside of the fixed pulley.

[0020] By adopting the above technical solution, the reliability of the reset action is improved by utilizing the energy storage characteristics of the spring, while the introduction of the fixed pulley effectively reduces the frictional resistance between the rope and the groove, making the rope traction action smoother and avoiding the wear problem caused by long-term friction, thus extending the service life of the components.

[0021] Preferably, a magnet is embedded on the inner side of the insulating sleeve, and the insulating sleeve is made of fur or plastic.

[0022] By adopting the above technical solution, the U-shaped support head is attracted to the magnet inside the insulating sleeve by energizing the electromagnet, which facilitates the subsequent reset operation. The insulating sleeve made of fur or plastic not only has good insulation performance, but also plays a buffering role in the fuse reset process, reducing the damage to the equipment caused by mechanical impact. At the same time, the choice of this material also takes into account the corrosion resistance and aging resistance in different environments, ensuring the long-term stable operation of the auxiliary reset component.

[0023] Preferably, an upper terminal block is fixedly installed on the top of the connecting plate, and a lower terminal block is fixedly installed on the bottom of the hinge seat. Both the upper terminal block and the lower terminal block are made of copper alloy.

[0024] By adopting the above technical solution, the upper and lower terminals made of copper alloy have excellent conductivity, which can effectively reduce resistance loss during current transmission and improve power transmission efficiency. At the same time, copper alloy also has good corrosion resistance and oxidation resistance, and can work stably for a long time in various harsh environments, reducing faults such as poor contact caused by terminal aging or corrosion, thereby ensuring the overall reliability and service life of the disconnector reset mechanism.

[0025] 1. Compared with existing technologies, this disconnector reset mechanism reduces the complexity and danger of manual reset work through the auxiliary reset component. The operator only needs to use the operating rod to lift it up a small distance, that is, to rotate the contact blade upwards at a small angle to reset it, reducing the difficulty of operation and physical exertion. At the same time, the magnet quickly and accurately resets the contact blade through electromagnetic attraction, avoiding the reset failure problem caused by mechanical jamming or positioning deviation in the traditional reset method.

[0026] 2. Compared with existing technologies, this disconnector reset mechanism utilizes a self-locking installation component. It can not only achieve precise angle adjustment of high-strength insulators through the mechanical linkage structure of worm gears, but also effectively prevent vibration loosening during long-term operation through its self-locking characteristics. Combined with the circumferential array of sockets on the mounting plate, operators can choose from multiple fixing positions according to actual needs. The mechanical locking between the plug rod and the socket forms a double insurance, which not only enhances the overall seismic performance, but also ensures the stability of the installation angle.

[0027] 3. Compared with the existing technology, the reset mechanism of this disconnecting switch adopts upper and lower terminals made of copper alloy material, which not only ensures excellent conductivity, but also extends the service life of the equipment through corrosion resistance. The design of the reset spring and the fixed pulley in the auxiliary reset component further improves the reliability and smoothness of the reset action, and finally realizes the high efficiency and safety of the fuse reset process.

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail below.

[0038] A disconnector reset mechanism includes a high-strength insulator 1 and a fixing ring 2. The fixing ring 2 is fixed to the outside of the high-strength insulator 1. A self-locking mounting assembly 3 and an auxiliary reset assembly 4 for mounting the high-strength insulator 1 are fixed to the outside of the fixing ring 2. A connecting plate 5 and a hinge seat 6 are fixedly installed on the outside of the high-strength insulator 1. The hinge seat 6 provides a stable support base for the contact blade 7, ensuring that the contact blade 7 can maintain an accurate movement trajectory during the opening and closing process. The connecting plate 5 is located above the hinge seat 6, and the contact blade 7 is fixedly installed on the hinge seat 6. The contact blade 7 is the core protection element. An operating ring 8 is fixed to the outside of the contact blade 7. The design of the operating ring 8 provides the operator with a convenient force application point, facilitating precise control during the reset process. A compression spring 13 is fixedly installed at the bottom of the connecting plate 5. The compression spring 13 achieves reliable contact and separation of the stationary contact piece 9 through elastic deformation. A stationary contact piece is fixedly installed on the other side of the compression spring 13. 9. The top of the contact blade 7 engages with the stationary contact piece 9. Waterproof plates 10 are fixed on both sides of the connecting plate 5. The waterproof plates 10 effectively block rainwater or humid air from corroding the internal electrical components, ensuring the stable operation of the equipment in harsh environments. At the same time, the waterproof plates 10 also play a certain mechanical protection role, preventing external objects from causing accidental damage to the contact blade 7 or the stationary contact piece 9. The stationary contact piece 9 is located between the two waterproof plates 10. The top of the connecting plate 5 is fixedly installed with an upper terminal 11, and the bottom of the hinge seat 6 is fixedly installed with a lower terminal 12. Both the upper terminal 11 and the lower terminal 12 are made of copper alloy. As key nodes for current transmission, the copper alloy material of the upper terminal 11 and the lower terminal 12 not only ensures low resistance loss, but also extends the service life of the terminals through excellent corrosion resistance, reducing contact failures caused by oxidation or corrosion, thereby improving the operational stability of the entire reset mechanism.

[0039] The working process of this application is as follows: The self-locking installation component 3 is manually fixed to the external support structure, and the initial fixation is achieved by using fasteners such as bolts. At this time, according to the actual installation environment requirements, the operator can flexibly adjust the angle of the self-locking installation component 3, which improves the adaptability and stability of the equipment installation. When the contact blade 7 is open or closed, the contact blade 7 rotates downward around the hinge seat 6 under the action of gravity, and separates from the stationary contact piece 9 to disconnect the circuit. During the rotation of the contact blade 7, it can drive the auxiliary reset component 4 to move in linkage. Under the action of the auxiliary reset component 4, the contact blade 7 will only rotate downward at a certain acute angle after being separated, and the contact blade 7 is not allowed to rotate completely and fall to a vertical state as in the traditional falling state. This makes it convenient for the operator to perform the reset operation with the operating rod. The reset angle is smaller, which is more labor-saving and convenient. The operator only needs to use the operating rod to lift it up a small distance, that is, to rotate the contact blade 7 upward at a small angle to reset it. It is not necessary to hook it first, then rotate it upward at a large angle and lift it upward a distance as in the traditional method, which reduces the difficulty of operation and physical consumption.

[0040] Furthermore, the setting of the fixing ring 2 can securely integrate the self-locking mounting component 3 and the auxiliary reset component 4 around the high-strength insulator 1, forming a compact and fully functional overall structure. This integrated design not only optimizes the spatial layout and reduces unnecessary component redundancy, but also improves the mechanical strength and environmental interference resistance of the entire disconnector reset mechanism. Moreover, the above-mentioned operating rod is similar to a clothes pole structure, including a rod body and a U-shaped support head located at the top of the rod body. The shape of the U-shaped support head is adapted to the cylindrical shape of the fuse tube, and an electromagnet is embedded at the bottom of the U-shaped support head.

[0041] The self-locking mounting assembly 3 includes a mounting bracket 301, a worm gear 302, and a mounting shaft 303 for mounting the high-strength insulator 1. The mounting bracket 301 is fixed to the outside of the fixing ring 2. One end of the worm gear 302 is rotatably mounted on the inner top wall of the mounting bracket 301. Both ends of the mounting shaft 303 are rotatably mounted inside the mounting bracket 301. A mounting plate 304 and a worm gear 306 are fixed to the outside of the mounting shaft 303. The worm gear 306 and the worm gear 302 mesh with each other. When the worm gear 302 rotates, it drives the mounting shaft 303 to rotate synchronously through its precise meshing with the worm gear 306. The rotation of the mounting shaft 303 then drives the mounting plate 304 to produce a precise angle change. This mechanical linkage structure allows the mounting angle of the high-strength insulator 1 to be flexibly adjusted according to actual needs, ensuring that the fuse can maintain the best working posture in different installation environments, thereby effectively improving the adaptability and stability of the equipment. The self-locking characteristic of the worm gear 302 of the turbine 306 automatically takes effect after the angle of the mounting plate 304 is adjusted to the correct position, effectively preventing the high-strength insulator 1 from loosening due to vibration during long-term operation, and further enhancing the safety and reliability of the equipment. The mounting plate 304 is provided with mounting holes 305. The other end of the worm gear 302 passes through the mounting bracket 301 and is fixed with a knob 308. The bottom of the mounting bracket 301 is provided with multiple insertion holes 307, which are arranged in a circumferential array. The bottom of the knob 308 is provided with a fixing groove 309. A return spring 310 is fixedly installed inside the fixing groove 309. The other end of the return spring 310 is fixed with a fixing block 311. The fixing block 311 is slidably engaged inside the fixing groove 309. The bottom of the fixing block 311 is fixed with a connecting bracket 312. One of the insertion holes 307 is inserted with a rod 313. The other end of the rod 313 is fixed to the top of the connecting bracket 312.

[0042] In use, the operator first manually pulls the connecting frame 312 according to the actual installation environment. The fixing block 311, the return spring 310, and the insertion rod 313 all move downward with the connecting frame 312. At this time, the insertion rod 313 disengages from the insertion hole 307, releasing the limiting effect on the insertion rod 313. Then, the knob 308 is rotated to drive the worm gear 302 to rotate. The meshing transmission between the worm gear 302 and the turbine 306 causes the mounting shaft 303 and the mounting plate 304 to rotate synchronously, realizing the high-strength... Precise adjustment of the installation angle of insulator 1 ensures that the fuse is in the best working condition. When the appropriate angle is adjusted, the fixing block 311, under the elastic force of the return spring 310, drives the connecting frame 312 and the plug rod 313 to move upward, so that the plug rod 313 automatically inserts into the corresponding plug hole 307, forming a mechanical lock. Together with the self-locking characteristics of the worm gear 306 and worm 302, it forms a double insurance, effectively preventing the high-strength insulator 1 from loosening due to vibration during long-term operation, and enhancing the overall seismic performance.

[0043] The auxiliary reset assembly 4 includes a side plate 401, a movable plate 403, a rope 407, and an insulating sleeve 408. The side plate 401 is fixed to the outside of the fixing ring 2. The top and bottom of the side plate 401 are provided with grooves 402. The movable plate 403 is slidably engaged inside the grooves 402 to prevent separation from the side plate 401. One side of the rope 407 is fixedly connected to the top of the movable plate 403. The insulating sleeve 408 is fixedly connected to the outside of the contact blade 7. The other end of the rope 407 is fixed to one side of the insulating sleeve 408. A reset spring is fixedly connected between the movable plate 403 and the grooves 402. Spring 404, inside the slide groove 402, a rotating shaft 405 is rotatably installed, and a fixed pulley 406 is fixed on the outside of the rotating shaft 405. The rope 407 is wrapped around the outside of the fixed pulley 406. The fixed pulley 406 effectively reduces the direct friction between the rope 407 and the edge of the slide groove 402 during traction, which not only makes the sliding of the rope 407 smoother and reduces energy loss, but also significantly extends the service life of the rope 407 and reduces the risk of breakage caused by frequent friction. A magnet 409 is embedded in the inner side of the insulating sleeve 408. The insulating sleeve 408 is made of fur or plastic material.

[0044] When this invention is in use, if a fault occurs in the power distribution network and maintenance is required, the contact blade 7 opens and closes. Under the action of gravity, the contact blade 7 rotates downward around the hinge seat 6. At this time, the insulating sleeve 408 fixed on the outside of the contact blade 7 moves downward synchronously. The downward movement of the insulating sleeve 408 tightens the rope 407. The rope 407 passes around the fixed pulley 406 and drives the moving plate 403 to slide in the slide groove 402. During the sliding process, the moving plate 403 compresses the reset spring 404, storing energy. When the fault is cleared and a reset operation is required, the operator only needs to use the operating rod to lift the contact blade 7 a small distance upward, causing it to rotate upward at a small angle. During this process, the magnet 409 inside the insulating sleeve 408 attracts the external electromagnetic device, assisting the contact blade 7 in accurately resetting. The reset spring 404 releases its stored energy, pushing the moving plate 403 to slide in the opposite direction. Under the action of the moving plate 403 and the fixed pulley 406, the rope 407 further guides the contact knife 7 to reset smoothly, avoiding the reset failure problem caused by mechanical jamming or positioning deviation in the traditional reset method. The whole reset process is efficient and safe, greatly reducing the difficulty of operation and physical consumption, and reducing the complexity and danger of manual reset work. Moreover, since the insulating sleeve 408 is made of fur or plastic, it not only has good insulation performance, but also plays a buffering role in the reset process, reducing the damage to the equipment caused by mechanical impact. At the same time, the choice of this material also takes into account the corrosion resistance and aging resistance in different environments, ensuring the long-term stable operation of the auxiliary reset component 4.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
