Description

Technical Field

[0001] The present invention relates to the technical field of insulator monitoring, and in particular to a transmission line insulator monitoring and protection device. Background Art

[0002] Transmission lines are constructed by using transformers to boost the voltage of electricity generated by generators, which is then connected to the transmission line via control devices such as circuit breakers. Transmission lines are divided into overhead transmission lines and cable lines.

[0003] Insulators are devices installed between conductors at different potentials, or between a conductor and a grounded structure, to withstand voltage and mechanical stress. Insulators come in many different types and shapes. While their structures and appearances vary significantly, they all consist of two main components: the insulating element and the connecting hardware.

[0004] Insulator contamination is one of the common faults in power systems. It is very important for the stable operation of power systems and the maintenance of electrical equipment. This is because the contamination of insulators will reduce their surface resistance and insulation strength, leading to creepage and breakdown faults. At the same time, contamination will also affect their appearance and bring inconvenience to equipment operation and maintenance.

[0005] The existing monitoring devices have the following deficiencies:

[0006] 1. Most of the time, it is necessary to manually climb up the circuit to observe the degree of dirtiness of the insulator, and automatic monitoring cannot be achieved, which is inefficient and has certain safety hazards.

[0007] 2. Although a small number of them can achieve monitoring work, the detection mechanism cannot automatically adjust the detection angle according to the external contour of the insulator, which has poor flexibility and reduces the detection accuracy.

[0008] 3. It is impossible to quickly disassemble and assemble the insulator, which is very inconvenient when the monitoring device needs to be repaired and maintained or the insulator needs to be replaced, reducing the practicality of the device. Summary of the Invention

The angle adjustment assembly 13 is provided on the outer wall of the L-shaped plate 11, and the laser emitter 12 is fixed to the angle adjustment assembly 13.

[0049] The quick disassembly and assembly mechanism is arranged on two mounting plates 1. The quick disassembly and assembly mechanism includes two telescopic components 14, four clamping claws 15 and four sliding components 16. Each telescopic component 14 is arranged on the outer wall of a mounting plate 1. Every two sliding components 16 are symmetrically arranged on the outer wall of a mounting plate 1. Each clamping claw 15 is fixed on a sliding component 16. The laser emitter 12, the driving component 6, the rotating component 10, the angle adjustment component 13 and each telescopic component 14 are electrically connected to the controller 2.

[0050] Reference Figures 1 to 9As shown, the drive assembly 6 includes a first motor 17 and a gear 18. The first motor 17 is inserted into the outer wall of one of the mounting plates 1, and the gear 18 is fixed on its output end. The gear 18 is meshed with the ring gear 3, and the first motor 17 is electrically connected to the controller 2. When the dirt detection of a part of the circumferential outer wall of the insulator 37 is completed, the first motor 17 is started by the controller 2, so that its output end drives the gear 18 to rotate. Since the gear 18 is meshed with the ring gear 3, the ring gear 3 and the conversion are slidably connected with the four arc guide rails 7 through two sliders 8. The ring gear 3 and the rotating ring 4 are respectively fixedly connected to the two ends of the connecting plate 5, thereby driving the connecting plate 5 to rotate through the ring gear 3 and the rotating ring 4, and then driving the laser emitter 12 on the connecting plate 5 to rotate, so as to perform dirt detection on the remaining part of the circumferential outer wall of the insulator 37 according to the above steps until the outer wall of the entire insulator 37 is detected.

[0051] Reference Figures 1 to 9 As shown, the rotating assembly 10 includes a second motor 19, a synchronous belt 20 and two synchronous wheels 21. The second motor 19 is fixedly arranged on the outer wall of the connecting plate 5. Each synchronous wheel 21 is rotated on the outer wall of the connecting plate 5 through a hinge shaft. The synchronous belt 20 is sleeved between the two synchronous wheels 21. The output end of the second motor 19 is fixedly connected to one end of one of the hinge shafts away from the connecting plate 5. The synchronous belt 20 is fixedly connected to the end of the lifting block 9 away from the L-shaped plate 11. The second motor 19 is electrically connected to the controller 2. When the device is clamped with the insulator 37 to achieve fixation Then, the laser emitter 12 is started through the controller 2, and a pulsed laser beam is used to irradiate the dirt on the surface of the insulator 37, thereby generating plasma characteristic spectrum data. Then, the second motor 19 is started through the controller 2, so that the synchronous wheel 21 on its output end rotates. Since the other synchronous wheel 21 is rotationally connected to the connecting plate 5, the two synchronous wheels 21 are connected by the synchronous belt 20, and the lifting block 9 is fixedly connected to the synchronous belt 20, thereby driving the lifting block 9 and a section of the laser emitter 12 to vertically descend, and irradiate and detect the insulator 37 along its axial direction.

[0052] Reference Figures 1 to 9As shown, the angle adjustment assembly 13 includes a third motor 22, a worm 23, a worm gear 24 and a rotating shaft 25. Two mounting blocks are fixedly provided on the outer wall of the L-shaped plate 11. The third motor 22 is inserted into one of the mounting blocks. The worm 23 is rotatably provided on the top of the other mounting block. The output end of the third motor 22 is fixedly connected to one end of the worm 23. The rotating shaft 25 is rotatably provided on the top of the L-shaped plate 11. The worm gear 24 is fixedly provided on the rotating shaft 25. The worm 23 is meshed with the worm gear 24. The laser emitter 12 is fixedly connected to the rotating shaft 25. The third motor 22 is connected to the controller 2 Electrical connection. Since the overall shape of the insulator 37 is umbrella-shaped, that is, it is uneven, blind spots will be encountered in the process of irradiating the insulator 37 along its axial direction to detect dirt. At this time, the third motor 22 is started by the controller 2, so that its output end drives the worm 23 to rotate. Since the worm wheel 24 is fixedly connected to the rotating shaft 25, the laser emitter 12 is fixedly connected to the rotating shaft 25, and the worm 23 is meshed with the worm wheel 24, the laser emitter 12 is driven to rotate longitudinally through the rotating shaft 25 to irradiate the blind spots with laser, thereby avoiding missed detection and improving the detection effect.

[0053] Reference Figures 1 to 9 As shown, each telescopic assembly 14 includes an electric push rod 26, a wedge-shaped top plate 27 and a connecting block 28. The electric push rod 26 is fixed on the outer wall of the mounting plate 1, and the wedge-shaped top plate 27 is slidably arranged on the outer wall of the mounting plate 1 through two slide bars 29. The connecting block 28 is fixed between the output end of the electric push rod 26 and the bottom of the wedge-shaped top plate 27. The electric push rod 26 is electrically connected to the controller 2. When the device passes through the insulator 37 until the two through holes 35 are aligned with the two ends of the insulator 37, the electric push rod 26 is started by the controller 2, so that its output end extends forward. Since its output end is fixedly connected to the bottom of the wedge-shaped top plate 27 through the connecting block 28, the bottom of the wedge-shaped top plate 27 is slidably connected to the mounting plate 1 through two slide bars 29, so that the wedge-shaped top plate 27 slides toward the end close to the through hole 35.

[0054] Reference Figures 1 to 9As shown, each sliding assembly 16 includes a wedge-shaped slider 30, a connecting rod 31, a slide 32 and a circular push rod 33. A guide rod is fixed on the outer wall of each mounting plate 1. Each slide 32 is slidably mounted on the outer wall of a guide rod. The connecting rod 31 and the circular push rod 33 are respectively fixed at both ends of the slide 32. The wedge-shaped slider 30 is fixed at one end of the connecting rod 31 away from the slide 32. Each clamping jaw 15 is fixedly connected to one end of a circular push rod 33 away from the slide 32. Each wedge slider 30 is slidably connected to a side wall of the wedge-shaped top plate 27. Since each wedge slider 30 is fitted and slidably connected to one side of the wedge-shaped top plate 27, When the wedge-shaped top plate 27 slides toward one end close to the through hole 35, the two wedge-shaped sliders 30 approach each other. Since the wedge-shaped slider 30 is fixedly connected to the end of the connecting rod 31 away from the slide 32, the other end of the connecting rod 31 and the circular push rod 33 are respectively fixedly connected to the two ends of the slide 32, and the slide 32 is slidably connected to the guide rod. Each clamping jaw 15 is fixedly connected to the end of a circular push rod 33 away from the slide 32, so that the two clamping jaws 15 approach each other, clamping one end of the insulator 37, and cooperating with the other clamping jaw 15 to clamp both ends of the insulator 37, thereby clamping and fixing the device and the insulator 37, which is convenient for online monitoring.

[0055] Reference Figures 1 to 9 As shown, a return spring 34 is sleeved on the outer wall of each guide rod, and an anti-slip column is fixed to the end of each guide rod away from the mounting plate 1. In the initial state, the return spring 34 is in a contracted state, and when the wedge-shaped top plate 27 slides toward the end close to the through hole 35, the two wedge-shaped sliders 30 slide to fit with the narrow end of the wedge-shaped top plate 27, so that the return spring 34 is transformed from a contracted state to a stretched state, thereby pushing the two slides 32 toward the end close to the through hole 35, driving the clamping claws 15 on the two circular push rods 33 to approach each other, thereby clamping the end of the insulator 37.

[0056] Reference Figures 1 to 9 As shown, each mounting plate 1 has an integrally formed outer wall with a through hole 35. When the transmission line insulator 37 needs to be monitored, the device is manually put on both ends of the insulator 37. The two through holes 35 facilitate the passage of the insulator 37 and provide avoidance space.

[0057] Reference Figures 1 to 9As shown, a data analysis module is installed inside the controller 2, and the data analysis module is electrically connected to the controller 2. Since the laser emitter 12 is electrically connected to the controller 2, the detected plasma characteristic spectrum data is sent to the controller 2, and the plasma characteristic spectrum data is analyzed by the data analysis module to detect and analyze the dirt on the surface of the insulator 37, so as to prevent corona discharge, insulation performance degradation, increased interphase insulation loss and other problems caused by the dirt on the insulator 37. The controller 2 is electrically connected to the PC end in the remote monitoring room, so as to facilitate the real-time sending of the analysis data to the PC end. The maintenance personnel can perform dirt analysis indoors and formulate relevant response measures to achieve the protection effect.

[0058] Reference Figures 1 to 9 As shown, a slide groove 36 for sliding two slide bars 29 is provided on the outer wall of each mounting plate 1. The slide groove 36 facilitates the sliding of the slide bar 29, thereby facilitating the smooth sliding of the wedge-shaped top plate 27 on the outer wall of the mounting plate 1, thereby improving the interference effect between the wedge-shaped top plate 27 and the two wedge-shaped sliders 30, thereby improving the stability of the clamping of the end of the insulator 37 and improving the installation stability of the device.

[0059] The working principle of the present invention is as follows: when it is necessary to monitor the transmission line insulator 37, the device is manually put on both ends of the insulator 37, and the two through holes 35 facilitate the insulator 37 to pass through, providing avoidance space.

[0060] When the device passes through the insulator 37 and is aligned with the two through holes 35 and the two ends of the insulator 37, the electric push rod 26 is started by the controller 2, so that its output end extends forward. Since its output end is fixedly connected to the bottom of the wedge-shaped top plate 27 through the connecting block 28, the bottom of the wedge-shaped top plate 27 is slidably connected to the mounting plate 1 through two sliding bars 29, so that the wedge-shaped top plate 27 slides toward the end closer to the through hole 35.

[0061] Since each wedge-shaped slider 30 is fitted with and slidably connected to one side of the wedge-shaped top plate 27, when the wedge-shaped top plate 27 slides toward the end close to the through hole 35, the two wedge-shaped sliders 30 are brought close to each other. Since the wedge-shaped slider 30 is fixedly connected to the end of the connecting rod 31 away from the slide plate 32, the other end of the connecting rod 31 and the circular push rod 33 are respectively fixedly connected to the two ends of the slide plate 32, and the slide plate 32 is slidably connected to the guide rod, each clamping jaw 15 is fixedly connected to the end of a circular push rod 33 away from the slide plate 32, so that the two clamping jaws 15 are brought close to each other, thereby clamping one end of the insulator 37, and cooperating with the other clamping jaw 15 to clamp both ends of the insulator 37, thereby clamping and fixing the device and the insulator 37, which is convenient for online monitoring.

[0062] In the initial state, the return spring 34 is in a contracted state. When the wedge-shaped top plate 27 slides toward the end close to the through hole 35, the two wedge-shaped sliders 30 slide to fit the narrow end of the wedge-shaped top plate 27, thereby causing the return spring 34 to change from a contracted state to a stretched state, thereby pushing the two slides 32 toward the end close to the through hole 35, driving the clamping claws 15 on the two circular push rods 33 to approach each other, thereby clamping the end of the insulator 37.

[0063] The slide groove 36 facilitates the sliding of the slide bar 29, thereby facilitating the smooth sliding of the wedge-shaped top plate 27 on the outer wall of the mounting plate 1, improving the interference effect between the wedge-shaped top plate 27 and the two wedge-shaped sliders 30, thereby improving the stability of the clamping of the end of the insulator 37 and improving the installation stability of the device.

[0064] After the device is clamped and fixed to the insulator 37, the laser emitter 12 is started by the controller 2, and a pulsed laser beam is used to irradiate the dirt on the surface of the insulator 37, thereby generating plasma characteristic spectrum data. Then, the second motor 19 is started by the controller 2, so that the synchronous wheel 21 on its output end rotates. Since the other synchronous wheel 21 is rotationally connected to the connecting plate 5, the two synchronous wheels 21 are connected by the synchronous belt 20, and the lifting block 9 is fixedly connected to the synchronous belt 20, thereby driving the lifting block 9 and a section of the laser emitter 12 to vertically descend, and irradiate and detect the insulator 37 along its axial direction.

[0065] Since the laser emitter 12 is electrically connected to the controller 2, the detected plasma characteristic spectrum data is sent to the controller 2, and the plasma characteristic spectrum data is analyzed by the data analysis module to detect and analyze the dirt on the surface of the insulator 37, so as to prevent corona discharge, insulation performance degradation, increased inter-phase insulation loss and other problems caused by the dirt of the insulator 37. The controller 2 is electrically connected to the PC end in the remote monitoring room, so that the analysis data can be sent to the PC end in real time. The maintenance personnel can perform dirt analysis indoors and formulate relevant response measures to achieve the protection effect.

[0066] Since the overall shape of the insulator 37 is umbrella-shaped, that is, it is uneven, blind spots will be encountered in the process of irradiating the insulator 37 along the axial direction to detect dirt. At this time, the third motor 22 is started by the controller 2, so that its output end drives the worm 23 to rotate. Since the worm wheel 24 is fixedly connected to the rotating shaft 25, the laser emitter 12 is fixedly connected to the rotating shaft 25, and the worm 23 is meshed with the worm wheel 24, the laser emitter 12 is driven by the rotating shaft 25 to rotate longitudinally, and the blind spots are irradiated with laser, thereby avoiding detection omissions and improving the detection effect.

[0067] When the dirt detection of a part of the circumferential outer wall of the insulator 37 is completed, the first motor 17 is started by the controller 2, so that its output end drives the gear 18 to rotate. Since the gear 18 is engaged with the ring gear 3, the ring gear 3 and the conversion are slidably connected with the four arc guide rails 7 through two sliders 8. The ring gear 3 and the swivel 4 are respectively fixedly connected to the two ends of the connecting plate 5, so that the connecting plate 5 is driven to rotate through the ring gear 3 and the swivel 4, and then the laser emitter 12 on the connecting plate 5 is driven to rotate, so as to perform dirt detection on the remaining part of the circumferential outer wall of the insulator 37 according to the above steps until the outer wall of the entire insulator 37 is detected.
