Description

[0002] As the core component of the power system, the safe and reliable operation of power equipment is of vital importance. As the cable is the key component of power transmission, as the power equipment runs longer, the insulation material of the cable will inevitably age, which can easily cause partial discharge. Partial discharge further accelerates the damage of the insulation material, which may eventually cause a short circuit or breakdown of the cable, leading to power outages and even fires and other serious safety accidents. Therefore, a device for detecting the insulation aging status of power equipment is needed.

[0003] The existing device for detecting the insulation aging status of power equipment performs offline detection on cables that have been used on power equipment for a period of time. A section of the cable is cut off and fixed on the tester to energize it. Then, the temperature of the cable surface and whether there is leakage are detected through temperature sensors and current sensors. This is done manually, and operations such as cutting and separating the outer sheath with pliers are inefficient. This not only causes the overall detection process to be time-consuming, but the instability of manual operation may also affect the accuracy and reliability of the detection, making it difficult to meet the needs of efficient and accurate detection of the insulation aging status of power equipment cables.

[0029] Specifically, when in use, the cut cable is placed on a clamping plate 64. Since a rubber pad 618 is provided on the inner side of the clamping plate 64, the cable fixing pressure loss is prevented, the cable surface is protected from damage, and the integrity of the cable in subsequent operations is ensured. A section of cable is left on each side of the two sets of clamping plates 64, and then the connecting plate 51 at the top output end is moved downward by starting the cylinder 4. The connecting plate 51 drives the multiple groups of infrared temperature sensors 53 and Hall effect current sensors 54 distributed on the inner side of the arc plate 52 to move downward. The diameter of the arc plate 52 is larger than the diameter of the cable, so that the multiple groups of infrared temperature sensors 53 and Hall effect current sensors 54 move to the outside of the cable. As the cylinder 4 drives the connecting plate 51 to move downward, the connecting plate 51 is moved with The extension plate 610 on one side moves downward to push the rack 1 68 downward, and the magnetic block 2 611 at the bottom of the extension plate 610 and the magnetic block 1 69 at the top of the rack 1 68 release the opposite poles of attraction and fixation, so that the rack 1 68 drives the protrusion 614 on one side to slide downward inside the notch 613 provided on the surface of the vertical plate 612, and the protrusion 614 drives the spring 615 to stretch and store force, and the rack 1 68 is meshed and connected with the gear 67, and the gear 67 drives the rotating rod 66 to rotate, and the rotating rod 66 drives the clamping plate 2 65 to rotate, and the clamping plate 2 65 rotates and closes with the clamping plate 1 64, so that the magnetic plate 1 616 and the magnetic plate 2 617 on one side of the clamping plate 1 64 contact and attract and fix with opposite poles, thereby clamping and fixing the two ends of the cable, ensuring that the cable is in a stable position and will not move during subsequent operations such as stretching, cutting and testing, thereby ensuring the accuracy and safety of the operation; As the rack 1 68 is pressed downward, the rack 1 68 also presses the fixed plate 71 downward. At this time, the clamping plate 1 64 and the clamping plate 2 65, the fixed plate 71 and the vertical plate 612 are slidably connected, and the fixed plate 71 drives the rotatably connected connecting seat 72 to move downward. The connecting seat 72 pushes the inclined plate 73 to move. The bottom end of the inclined plate 73 drives the driven plate 75 in the groove 61 by means of the movable seat 74 rotatably connected thereto. The inner part slides toward the outer side, thereby stretching and straightening the two ends of the cable fixed by the clamp. Stretching the cable can keep the cable in a straight state in subsequent cutting and testing operations, which is convenient for precise operation. For testing, the straightened cable can make the test result more accurate, avoid the detection error caused by the bending of the cable, and the driven plate 75 moves the groove 61 away from one end of the cable to squeeze the switch 76. Since the two sets of switches 76 are electrically connected to the hydraulic cylinder 82 and the motor 85 respectively, the hydraulic cylinder 82 and the motor 85 are driven to start. At this time, the cable is in a state of being fixed after the stretching is completed. The drive of the hydraulic cylinder 82 drives the round shell 83 at the output end to move toward the cable, so that the four sets of cutters 812 are on the outside of the cable, and the motor 85 fixedly installed on one side of the round shell 83 through the folding plate 84 drives the turntable 86 to rotate. The turntable 86 drives the four groups of slide grooves 87 on the surface to rotate. The rotation of the four groups of slide grooves 87 causes the slider 88 to slide from the end of the slide groove 87 away from the center of the turntable 86 to the end close to the center of the circle, so that the four groups of sliders 88 drive the corresponding slide plate 89 on one side to slide toward the cable in the short groove opened on the surface of the built-in plate 810. The four groups of slide plates 89 drive the cutter 812 fixed by the support plate 811 on one side to cut the outer skin of the cable, and then start the hydraulic cylinder 82 to move in the reverse direction, so that the hydraulic cylinder 82 moving in the reverse direction drives the four groups of cutters 812 to peel off the cut cable outer skin. Compared with manual operation, the automated cutting and peeling method is more efficient and accurate, and can reduce the safety risks brought by manual operation, while ensuring the quality of cutting and peeling, and preparing for subsequent power-on and detection operations; Then, the hydraulic rod 93 is started, and the hydraulic rod 93 drives the conductive clamp 94 at the output end to move toward the wire leaking from the cable, and the power block 91 is started to output current to the electrically connected conductive clamp 94, and at the same time, the electric push rod 95 fixed at the grip of the conductive clamp 94 is started to drive the ring 96 at the output end to pull the pressing handle, so that the conductive clamp 94 opens to clamp the wire, and further completes the power-on, which can accurately connect the conductive clamp to the cable wire, ensure the stability and reliability of the power-on, and provide the necessary power-on conditions for the subsequent insulation aging detection; Finally, the motor 31 fixedly installed on one side of the frame 2 is started, and the motor 31 drives the bidirectional screw rod 32 at the output end to rotate. One end of the bidirectional screw rod 32 rotates with the placement groove opened inside the frame 2, and the bidirectional screw rod 32 drives the two groups of moving blocks 33 connected by threads to move in opposite directions. The two groups of moving blocks 33 drive the detection component 5 to move through the cylinder 4 to detect the insulation aging status of the cable, and evenly detect the cable, improve the coverage and accuracy of the detection, timely discover the cable insulation aging problem, and ensure the safe operation of the power equipment.
