Description

Technical Field

[0001] This utility model belongs to the technical field of cable fault testing equipment, and in particular relates to a remote-controlled cable fault testing equipment. Background Technology

[0002] The high-voltage ball gap device is a crucial connecting element used in high-voltage cable fault location, linking the high-voltage generator to the faulty cable. During operation, it connects to both the high-voltage generator and the main equipment operated by the personnel via a sampling coil. During operation, it is essential to ensure both a sufficiently high voltage for cable fault location and the operator's safety. However, because the test voltage and the distance of the energized ball gap need to be adjusted multiple times, repeated cycles of voltage increase, decrease, power outage, and grounding wire placement are necessary. This not only increases the fault location time but also raises the operational risks. When performing cable fault detection, the test voltage must be compatible with the cable's physical parameters. High voltage must first be supplied, and a pulsed high voltage must be applied to the faulty cable through the sampling ball gap. If the fault point does not discharge, the power must be turned off, a ground wire must be connected, and the sampling ball gap must be manually adjusted. Then the cable voltage must be increased again to find the cable fault point. If it still has not discharged or discharges prematurely before reaching the test voltage, the power must be turned off again, a ground wire must be connected, and the sampling ball gap must be manually adjusted again. This process is repeated multiple times until the fault point is found. The entire testing process is not only cumbersome, but also poses a great safety hazard because the operators manually contact the high voltage equipment (the test voltage is not less than 10 kV). It cannot adapt to the most advanced application technology and high-speed production pace. Utility Model Content

[0003] This utility model aims to solve the problems of high difficulty and workload for operators when detecting cable faults, and the frequent manual operation of high-voltage testing equipment by operators at close range. It provides a remote-controlled cable fault testing device that is easier to operate, improves control accuracy and equipment reliability, and effectively ensures personal safety.

[0004] To achieve the above-mentioned utility model objectives, this utility model provides a remote-controlled cable fault testing device, characterized in that it includes a motor, a belt, an inner drive shaft, a right-hand helical device, a ball gap device, a battery pack, a remote control receiver controller, and a wireless remote controller; one of the two balls in the ball gap device is movable, referred to as the moving ball; the motor is connected to the inner drive shaft via the belt, the right-hand helical device is installed at the center of the inner drive shaft, the right-hand helical device is connected to the moving ball, the remote control receiver controller is connected to the motor, the battery pack is connected to the remote control receiver controller, and the remote control receiver controller and the wireless remote controller are complementary components;

[0005] The remote control receiver is a dual-channel wireless remote control receiver. The wireless remote control has buttons A and B. Pressing button A on the handheld wireless remote control activates the receiver, which outputs a 6-volt positive DC current. This current is applied to the DC geared motor, causing it to rotate forward. The rotation of the motor's shaft pulley, belt, and inner drive shaft pulley causes the right-hand helical device on the inner drive shaft to rotate in reverse, increasing the length of the helical device and moving the moving ball forward.

[0006] Pressing button B on the handheld wireless remote control activates the wireless remote control receiver, which outputs a reverse DC voltage. This voltage is applied to the DC geared motor, causing it to run in reverse. The rotation of the motor's shaft pulley, belt, and inner drive shaft pulley drives the right-hand helical device on the inner drive shaft to rotate clockwise, reducing the length of the right-hand helical device and causing the moving ball to move backward.

[0007] This invention, without interrupting high voltage operation, uses a wireless remote control device to adjust the distance between the balls, enabling remote start-up, stop-up, test voltage adjustment, timing, and other test actions for the system. This allows for remote cable fault testing, saving operation time, ensuring operator safety, making operation more convenient, improving control accuracy and equipment reliability, and effectively guaranteeing personal safety. This technology is highly versatile and has significant potential for widespread application. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model;

[0009] The components include: 1. Motor; 2. Belt; 3. Internal drive shaft; 4. Right-hand screw mechanism; 5. Moving ball; 6. Battery pack; 7. Remote control receiver and controller; 8. Wireless remote control. Detailed Implementation

[0010] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a remotely controlled cable fault testing device.

[0011] Reference Figure 1 The remote-controlled cable fault testing equipment includes a motor 1, a belt 2, an internal drive shaft 3, a right-hand helical device 4, a ball gap device, a battery pack 6, a remote control receiver 7, and a wireless remote controller 8. One of the two balls in the ball gap device is movable, referred to as the moving ball 5.

[0012] Motor 1 is connected to inner drive shaft 3 via belt 2. Right-hand screw device 4 is installed at the center of inner drive shaft 3. Right-hand screw device 4 is connected to moving ball 5. Remote control receiver controller 7 is connected to motor 1. Battery pack 6 is connected to remote control receiver controller 7. Remote control receiver controller 7 and wireless remote control 8 are a matching component.

[0013] The remote control receiver 7 is a dual-channel wireless remote control receiver with blue and brown wires at the output end. The wireless remote control 8 has buttons A and B. When button A is pressed on the handheld wireless remote control 8, the wireless remote control receiver 7 receives the signal, outputting 6V DC power with the blue wire as positive and the brown wire as negative. This power is applied to the DC geared motor 1, causing the motor 1 to rotate forward. The rotation of the pulley on the shaft end of the motor 1, the belt 2, and the pulley on the inner drive shaft 3 drives the right-hand helical device 4 on the inner drive shaft to rotate in reverse, increasing the length of the right-hand helical device 4 and moving the moving ball 5 forward. This transforms the forward rotation of the motor 1 into the forward movement of the moving ball 5 through the ball gap, thereby reducing the ball gap distance without interrupting the high-voltage power supply.

[0014] Pressing button B on the handheld wireless remote control 8 activates the wireless remote control receiver 7. Using the brown wire as positive and the blue wire as negative, it outputs 6V DC power, which is applied to the DC geared motor 1, causing motor 1 to reverse. The rotation of the pulleys on the motor 1's shaft, belt 2, and inner drive shaft 3 drives the right-hand helical device 4 on the inner drive shaft 3 to rotate clockwise, reducing the length of the helical device 4 and moving the moving ball 5 backward. Reversing the rotation of motor 1 transforms the movement of the moving ball through the ball gap into a backward movement, thus increasing the ball gap distance without interrupting the high-voltage operation.
