Description

Technical Field

[0001] This invention relates to the field of indicator technology, and in particular to a remote fault indicator for power transmission and distribution lines and its detection method. Background Technology

[0002] Overhead lines, as a crucial component of power transmission, are exposed to the natural environment and are susceptible to faults due to various factors, such as lightning, wind and rain, animal damage, and line aging. These faults not only affect the reliability of power supply but may also threaten the stable operation of the power grid. Traditional detection methods, such as manual inspections and relay protection devices, while capable of detecting and handling faults to some extent, have many limitations, including long inspection cycles, low efficiency, and inaccurate fault location due to malfunctions or failures of relay protection devices. Indicators, however, can provide timely monitoring of current faults.

[0003] CN104267292A discloses a fault indicator for power transmission lines, comprising a fault indicator fixed to the power transmission cable. The fault indicator includes a flip-plate coil and an indicator plate. A magnetic switch is located on one side of the flip-plate coil, and a magnet supported on the indicator plate is located below the magnetic switch. A control module is located above the magnetic switch, and the control module is connected to a polymer lithium battery. The polymer lithium battery is connected to a CT power-taking module, which is connected to a fixed stainless steel soft magnetic sheet and a movable stainless steel soft magnetic sheet. This invention is simple to install and does not require a separate data receiving host. The fault indicator can be easily installed by simply attaching it to the power cable of the transmission line, saving significant manpower, material resources, and financial resources, avoiding the impact of environmental factors, and improving the reliability and stability of the equipment operation.

[0004] The above-mentioned patents still have some problems when used: When existing indicators are installed on cables, a spring clip is installed at the top of the indicator. The indicator is installed on the cable by means of a spring clip. However, when opening the spring clip on the indicator, most of the time it is necessary to use an installation auxiliary component to install the indicator. Since the installation environment of the indicator is usually high-altitude work, it is not possible to open and fix the spring clip on the indicator with both hands. In addition, multiple indicators need to be installed on multiple cables. Using auxiliary tools to open the spring clip on the indicator is very troublesome when operating at height. Summary of the Invention

[0005] The purpose of this application is to provide a remote fault indicator for power transmission and distribution lines and its detection method. It enables the clamping plate on the opening and closing component to be opened by adjusting the component. When the clamping plate moves to the surface of the cable, the clamping plate is pulled by the spring force of the first spring and thus the clamping plate is locked onto the surface of the cable by the pull of the rotating plate on the limiting component. No auxiliary components are required for installation, which increases the safety of high-altitude operations.

[0014] Preferably, the adjusting plate is slidably connected to a pair of positioning rods, the top ends of the pair of positioning rods are fixedly connected to a collar, a second spring is sleeved on the pair of positioning rods, the two ends of the second spring are fixedly connected to the bottom surface of the collar and the top surface of the adjusting plate, respectively, a cylinder is fixedly connected to the middle position of the bottom surface of the adjusting plate, the surface of the cylinder is provided with an inclined groove, a rotating shaft is inserted into the inside of the cylinder, the bottom end of the rotating shaft is rotatably connected to the middle position of the limiting plate, a pin is fixedly connected to the surface of the rotating shaft, the pin is slidably connected to the inside of the inclined groove, and a rotating plate is fixedly connected to the lateral position of the bottom surface of the rotating shaft.

[0015] The present invention also provides a method for detecting a remote fault indicator for power transmission and distribution lines, comprising: The sensor, installed inside the indicator, monitors data such as current and voltage in real time.

[0016] In summary, the technical effects and advantages of this invention are as follows: 1. The present invention has a reasonable structure. The indicator body is fixed to the cable by opening and closing the clamp plate. When the clamp plate is opened, the sleeve on the arc plate drives the rotating rod to rotate. The rotation of the rotating rod drives the gear to rotate, thereby facilitating the up and down movement of the gear plate and controlling the opening and closing of the clamp plate.

[0017] 2. In this invention, when the clamping plate is opened, the toothed plate moves downward as a whole. The movement of the toothed plate causes the rotating rod on the gear to rotate, and then the pulley on the side seat slides on the sliding rod, increasing the stability of the toothed plate movement. The movement of the toothed plate causes the bracket on the docking plate to move, which facilitates the horizontal plate to squeeze the first spring on the limiting rod. At this time, the clamping plate is in an open state, which makes it convenient for the clamping plate to hold the surface of the cable.

[0018] 3. In this invention, when the clamping plate is opened, the pin is inserted into the round hole by the elastic force of the second spring. The pull of the rotating plate causes the rotating shaft to rotate, which facilitates the pin sliding inside the inclined groove. The cylinder pushes the adjusting plate upward, which facilitates the pin on the clamping plate to disengage from the round hole. Then, the elastic force of the first spring causes the bracket on the horizontal plate to drive the first shaft seat to move upward, which facilitates the mating plate to drive the toothed plate to move upward, so that the clamping plate is engaged with the surface of the cable, completing the overall installation of the indicator body. This operation method only requires one hand to complete the overall installation of the indicator body without the need for auxiliary tools. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1-7 The remote fault indicator for power transmission and distribution lines shown includes an indicator body 1, a warning light 101 fixedly installed on the bottom surface of the indicator body 1, a cover 102 fixedly installed on the lower part of the surface of the indicator body 1, a top seat 103 provided at the top of the indicator body 1, an L-shaped groove 104 opened on the surface of the top seat 103, a locking post 105 being engaged inside the L-shaped groove 104, one end of the locking post 105 being fixedly connected to the surface of the indicator body 1; it also includes an opening and closing component, an adjusting component, and a limiting component. The opening and closing component is located at the top of the top seat 103 for suspending the indicator body 1 as a whole on the line, the adjusting component is located on the limiting plate 2 for controlling the opening and closing of the clamping plate 207, and the limiting component is located on the limiting plate 2 for use in conjunction with the adjusting component.

[0024] Specifically, it should be noted that the indicator body 1 monitors the cable through a sensor, and the working principle is based on existing technology, which will not be elaborated on here.

[0025] As one implementation method in this embodiment, according to the appendix Figure 5As shown, the opening and closing assembly includes a limiting plate 2 fixedly installed at the center of the top surface of the top seat 103. Through slots 201 are provided on both sides of the limiting plate 2. A fixing seat 202 is fixedly connected to the inner wall of the limiting plate 2. A rotating rod 203 is rotatably connected to the horizontal position of the fixing seat 202. A gear 204 is fixedly connected to the rotating rod 203. Sleeves 205 are fixedly connected to both ends of the rotating rod 203. An arc plate 206 is fixedly connected to the surface of the sleeve 205. The other end of the arc plate 206 is fixedly connected to the clamping plate 207.

[0026] Specifically, the indicator body 1 is fixed to the cable by the opening and closing of the clamp 207. When the clamp 207 is opened, the sleeve 205 on the arc plate 206 drives the rotating rod 203 to rotate. The rotation of the rotating rod 203 drives the gear 204 to rotate, thereby facilitating the up and down movement of the gear plate 3 and controlling the opening and closing of the clamp 207.

[0027] As one implementation method in this embodiment, according to the appendix Figure 6 As shown, the adjusting assembly includes a toothed plate 3 that fits onto the gear 204. The toothed plate 3 is slidably connected to the inner wall of the limiting plate 2. A pair of toothed plates 3 are provided, and a mating plate 301 is fixedly connected between the bottom positions of the pair of toothed plates 3. A side seat 302 is fixedly connected to the middle position of one side of the mating plate 301. A pair of pulleys 303 are rotatably connected to the side seat 302. The pulleys 303 are slidably connected to the slide rod 304. The top end of the slide rod 304 is fixedly connected to the first shaft seat 305. One end of 05 is fixedly connected to the outer surface of the limiting plate 2. A bracket 306 is fixedly connected to the middle position of the other side of the docking plate 301. A horizontal plate 307 is fixedly connected to the other end of the bracket 306 in a horizontal position. The two ends of the horizontal plate 307 are slidably connected to the limiting rod 308. The bottom end of the limiting rod 308 is fixedly connected to the limiting plate 2. A first spring 310 is sleeved on the limiting rod 308. The two ends of the first spring 310 are fixedly connected to the bottom wall of the limiting plate 2 and the bottom surface of the horizontal plate 307, respectively.

[0028] Specifically, when the clamping plate 207 is opened, the toothed plate 3 moves downward as a whole. The movement of the toothed plate 3 causes the rotating rod 203 on the gear 204 to rotate. Then, the pulley 303 on the side seat 302 slides on the sliding rod 304, increasing the stability of the movement of the toothed plate 3. The movement of the toothed plate 3 causes the bracket 306 on the docking plate 301 to move, which makes it easier for the horizontal plate 307 to press the first spring 310 on the limiting rod 308. At this time, the clamping plate 207 is in an open state, which makes it easy for the clamping plate 207 to clamp the surface of the cable.

[0029] In this embodiment, according to the appendix Figure 7As shown, the limiting assembly includes a pair of second bearing seats 4 fixedly mounted on the limiting plate 2. A crossbar 401 is rotatably connected between the pair of second bearing seats 4. Arm plates 402 are fixedly connected to both ends of the crossbar 401. A sliding groove 403 is provided on the arm plate 402. A roller 404 is slidably connected inside the sliding groove 403. The roller 404 is rotatably connected to one end of the docking rod 405. The middle position of the docking rod 405 is fixedly connected to the base 406. The top end of the base 406 is fixedly connected to the bracket 306. A turntable 407 is fixedly connected to the middle position of the crossbar 401. Several sets of round holes 408 are provided on the surface of the turntable 407. A pin 409 is inserted into one of the round holes 408. The top end of the pin 409 is fixedly connected to the clamping plate 410. The top end of the clamping plate 410 is fixedly connected to the base 406. A fixed connection is made to one end of the adjusting plate 411. The adjusting plate 411 is slidably connected to a pair of positioning rods 412. A collar 413 is fixedly connected to the top of the pair of positioning rods 412. A second spring 414 is sleeved on the pair of positioning rods 412. The two ends of the second spring 414 are fixedly connected to the bottom surface of the collar 413 and the top surface of the adjusting plate 411, respectively. A cylinder 415 is fixedly connected to the middle of the bottom surface of the adjusting plate 411. A groove 416 is opened on the surface of the cylinder 415. A rotating shaft 417 is inserted inside the cylinder 415. The bottom end of the rotating shaft 417 is rotatably connected to the middle of the limiting plate 2. A pin 418 is fixedly connected to the surface of the rotating shaft 417. The pin 418 is slidably connected inside the groove 416. A rotating plate 419 is fixedly connected to the lateral position of the bottom surface of the rotating shaft 417.

[0030] Specifically, when the clamping plate 207 is opened, the pin 409 is inserted into the round hole 408 by the elastic force of the second spring 414. The pull of the rotating plate 419 causes the rotating shaft 417 to rotate, which facilitates the sliding of the pin 418 inside the inclined groove 416. The cylinder 415 pushes the adjusting plate 411 upward, which facilitates the pin 409 on the clamping plate 410 to disengage from the round hole 408. Then, the elastic force of the first spring 310 causes the bracket 306 on the horizontal plate 307 to drive the first shaft seat 305 to move upward, which facilitates the mating plate 301 to drive the toothed plate 3 to move upward, so that the clamping plate 207 is engaged with the surface of the cable, completing the overall installation of the indicator body 1.

[0031] The working principle of this invention is as follows: The indicator body 1 is fixed to the cable by the opening and closing of the clamp 207. When the clamp 207 is opened, the sleeve 205 on the arc plate 206 drives the rotating rod 203 to rotate. The rotation of the rotating rod 203 drives the gear 204 to rotate, thereby facilitating the up and down movement of the gear plate 3 and controlling the opening and closing of the clamp 207.

[0032] When the clamping plate 207 is opened, the toothed plate 3 moves downward as a whole. The movement of the toothed plate 3 causes the rotating rod 203 on the gear 204 to rotate. Then, the pulley 303 on the side seat 302 slides on the sliding rod 304, increasing the stability of the movement of the toothed plate 3. The movement of the toothed plate 3 causes the bracket 306 on the docking plate 301 to move, which makes it easier for the horizontal plate 307 to press the first spring 310 on the limiting rod 308. At this time, the clamping plate 207 is in the open state, which makes it easy for the clamping plate 207 to clamp the surface of the cable.

[0033] When the clamping plate 207 is opened, the pin 409 is inserted into the round hole 408 by the elastic force of the second spring 414. The pull of the rotating plate 419 causes the rotating shaft 417 to rotate, which facilitates the sliding of the pin 418 inside the inclined groove 416. The cylinder 415 pushes the adjusting plate 411 upward, which facilitates the pin 409 on the clamping plate 410 to disengage from the round hole 408. Then, the elastic force of the first spring 310 causes the bracket 306 on the horizontal plate 307 to drive the first shaft seat 305 to move upward, which facilitates the mating plate 301 to drive the toothed plate 3 to move upward, so that the clamping plate 207 is engaged with the surface of the cable, completing the overall installation of the indicator body 1.

[0034] The present invention also provides a method for detecting a remote fault indicator for power transmission and distribution lines, comprising: The sensor, installed inside the indicator, monitors data such as current and voltage in real time. When a fault occurs in the line, the sensor will detect abnormal changes in current or voltage and transmit this signal to the monitoring center through the communication module. When the monitoring center receives the signal, it will immediately analyze and process it to determine the type and location of the fault and issue an alarm, so that maintenance personnel can take timely measures to repair it.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
