Description

Technical Field

[0001] The invention relates to the technical field of overhead high-voltage cable inspection, in particular to an overhead high-voltage cable line current detection clamp. Background Art

[0002] Overhead high-voltage cables are widely used in power transmission. To ensure their safety, regular testing of the current inside the cables is a crucial part of circuit inspections. Current testing can promptly identify cable overloads and local faults causing abnormal current flow. This allows appropriate measures to be taken to prevent problems such as overheating and insulation damage caused by these current flow problems, thereby preventing power outages and even serious consequences like fires.

[0003] A current clamp is an instrument used to measure the current in an operating electrical circuit. It typically consists of a current transformer and an ammeter. The conductor of the circuit being measured passes through an iron core coil, which acts as the primary coil of the current transformer. The current passing through it induces a current in the secondary coil. The reading from the ammeter connected to the secondary coil serves as an estimate of the current in the circuit being measured.

[0004] The existing device mainly uses external lifting equipment to set the current detection clamp on the outer wall of the overhead high-voltage cable. The existing technology is similar to a current detection clamp for current detection of overhead high-voltage cable lines. The structure with publication number CN113884743A includes a connector, a main bracket is assembled on the inner side of the connector, and a measuring clamp is assembled on the inner side of the main bracket. This invention effectively solves the problem that the existing overhead high-voltage cable measuring clamp needs to be manually carried when in use, which is inconvenient to use and is not convenient for measuring current during line inspection. However, there are still areas that can be optimized in this device.

[0005] The existing device mainly uses a lifting device to drive the current detection clamp to be installed on the outer wall of the cable, which makes it easy for the lifting component to guide the high-voltage current of the cable to the ground, thereby causing accidental electric shock to ground operators. Secondly, some devices make it difficult to drive the inspection equipment to walk along the cable line for inspection, which makes it inconvenient to find and accurately locate the damaged parts of the cable line. Finally, some devices are difficult to install and disassemble between the drone and the detection clamp, making it difficult for the drone to carry the detection components one by one to be installed on the same group of overhead cables, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an overhead high-voltage cable line current detection clamp is proposed. Summary of the Invention

At the same time, the AC induced electricity is converted into DC induced electricity through the rectifier 311, and recorded and stored by the current data recorder 312.

[0031] The interior of the protective frame 108 is provided with a disassembly and assembly mechanism 4, which includes a slider 401.

An electromagnet 405 is provided on the left side of the magnetic block 404. The top of the outer wall of the electromagnet 405 is fixedly connected to the bottom of the support platform of the drone 101. Through this design, it is achieved that by activating the electromagnet 405 to adsorb the magnetic block 404, the magnetic block 404 can drive the slider 401 to slide to the left through the push-pull rod 402. The left side of the slider 401 is located on the outer ring of the push-pull rod 402, and is fixedly connected to a compression spring 403. The left end of the compression spring 403 is fixedly connected to the right side of the vertical plate of the protective frame 108, and the right side of the slider 401 is fixedly connected to a clamping sleeve 406.

Through this design, the clamping sleeve 406 can be sleeved on the middle of the outer wall of the positioning pin 407, which facilitates the disassembly and assembly of the mounting frame 102.

[0032] Working principle: When the mounting frame 102 needs to be moved, the servo motor 201 is first started through the remote sensing controller 104, and the servo motor 201 drives the transmission worm 202 to rotate clockwise, and the transmission worm 202 engages to drive the transmission worm gear 203 to rotate, and the transmission worm gear 203 drives the transmission screw 204 to rotate within a limited position, and the transmission screw 204 drives the pushing screw barrel 205 to slide to the right, and the pushing screw barrel 205 drives the pushing block 206 to slide within the limited position on the inner wall of the limiting frame 207, and the pushing block 206 drives the pressing block 208 to slide upward, and the pressing block 208 drives the lifting frame 107 to slide synchronously, and the lifting frame 107 stretches the telescopic cylinder 209 and the tension spring 210 and drives the upper part of the outer wall of the driving wheel 212 to be close to the lower part of the outer wall of the cable. Then, the drive motor 211 is started through the remote sensing controller 104, and the drive motor 211 drives the drive wheel 212 to rotate in a limited position, so that the drive wheel 212 drives the mounting frame 102 and the components thereon to move along the cable, thereby realizing the moving operation of the mounting frame 102.

[0033] When the cable needs to be tested, the first bevel gear 301 is first driven to rotate synchronously by the transmission screw 204, the first bevel gear 301 engages and drives the second bevel gear 302 to rotate, the second bevel gear 302 drives the symmetrical screw 303 to limit the rotation, the symmetrical screw 303 drives the push screw sleeve 304 to slide symmetrically, and the push screw sleeve 304 drives the sliding frame 105 to slide synchronously. The sliding frame 105 drives the clamping ring 305 to slide synchronously, so that the clamping ring 305 cooperates with the ball 306 to clamp the outer wall of the cable. At the same time, the sliding frame 105 can drive the first core clamping arm 307 and the second core clamping arm 308 to approach synchronously, so that the first core clamping arm 307, the second core clamping arm 308 and the fixed core 309 form a closed core ring, so that the winding group 310 can sense the current inside the cable, and at the same time, the AC induced electricity is converted into DC induced electricity through the rectifier 311, and is recorded and stored by the current data recorder 312, thereby realizing the cable testing operation.

[0034] When the mounting frame 102 needs to be disassembled or assembled, the electromagnet 405 is first activated through the remote control component of the drone 101. The electromagnet 405 attracts the magnetic block 404, so that the magnetic block 404 can drive the slider 401 to slide to the left through the push-pull rod 402. The slider 401 drives the clamping sleeve 406 to slide synchronously and compress the compression spring 403. Then, the positioning pin 407 at the bottom of the mounting frame 102 is inserted into or removed from the pin hole on the support platform of the drone 101. Finally, the electromagnet 405 is turned off, so that the compression spring 403 drives the slider 401 and the clamping sleeve 406 to slide to the right and automatically reset, completing the disassembly and assembly operation of the mounting frame 102. The operation ends here.
