Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power facility maintenance, and in particular to a high-voltage line joint heating defect processing device. BACKGROUND

[0002] As the core carrier of power transmission, the stable operation of transmission and distribution lines is directly related to power supply reliability and social power safety. In the transmission and distribution lines, the connection point is an essential structure for realizing long-distance laying of the line, that is, the ends of two high-voltage lines are connected to realize the extension of the transmission line, which is widely used in lines of various voltage levels. However, due to factors such as installation process, material aging, mechanical vibration and environmental erosion, the connection point is prone to local overheating, forming a heating defect. This defect may accelerate equipment deterioration, or even cause serious accidents such as fuse blowing, fire and line trip.

[0003] The causes of the heating defect can be attributed to two core factors: one is that the contact resistance of the joint is too large, and the oxidation and loosening of the contact surface cause the resistance to increase, resulting in a sharp increase in Joule heat; the other is that the line load current is too large, and the peak current far exceeds the design margin, further aggravating the heating effect. At present, the conventional treatment methods for heating defects include power-off defect elimination and live working, but the above methods have significant limitations:

[0004] Power-off defect elimination: requires load transfer or scheduled power outage, which is complex and time-consuming, directly affects power supply reliability, and is prone to user complaints;

[0005] Live working: traditional manual live tightening or replacement of equipment requires personnel to directly approach high-voltage equipment, which is risky, low in efficiency, and difficult to operate on complex joint structures such as drain rows.

[0006] Therefore, there is an urgent need for a device that can quickly and safely eliminate the heating defect of the high-voltage line joint without power outage and load transfer, to gain buffer time for subsequent thorough repair, in order to meet the requirement of high power supply reliability. SUMMARY

[0014] The X direction is the axial direction of the high-voltage wire.

[0015] As a preferred technical solution, the sliding assembly comprises a roller and a first driver. A groove is arranged on the outer periphery of the roller. The roller is in rolling connection with the high-voltage wire through the groove. The first driver is fixedly installed on the support and is in transmission connection with the roller. The first driver is used to drive the roller to rotate so as to drive the support to move along the X direction.

[0016] As a preferred technical solution, the support comprises a box body and a support. The support is fixedly arranged at the top end of the box body. The bottom of the support and the top of the box body define a threading space for the high-voltage wire to pass through. The first driver is arranged on the support. The clamping portion is in sliding connection with the box body.

[0017] As a preferred technical solution, a cavity is arranged in the box body. Two through holes are respectively arranged on the two sides of the box body along the X direction. The two through holes are respectively in communication with the cavity.

[0018] The high-voltage wire joint heating defect processing device further comprises a distance adjusting assembly. The distance adjusting assembly comprises a first gear, two first racks and a second driver. The first gear is arranged in the cavity. The two first racks are respectively arranged on the opposite sides of the first gear. The second driver is fixedly arranged in the box body and is in transmission connection with the first gear. The second driver is used to drive the first gear to rotate relative to the box body. One end of each first rack is fixedly connected to a clamping portion. The other end of each first rack extends along the X direction and is in meshing connection with the first gear through a through hole.

[0019] The second driver is in signal connection with the controller.

[0020] As a preferred technical solution, the clamping part includes: a mounting base, a gripper, a drive mechanism, and an electrical connector. The mounting base is connected to the housing. The gripper is located at the top of the mounting base. The drive mechanism is located on the mounting base and is used to drive the gripper to open or close. The electrical connector is fixedly connected to the mounting base. The wire is fixedly connected to the electrical connector. The drive mechanism is signal-connected to the controller.

[0021] As a preferred technical solution, the inner peripheral wall of the mounting base is provided with sliding grooves on opposite sides, and the gripper includes two gripper bodies.

[0022] The driving mechanism includes: a second gear, two second racks, and a third driver. The second gear is mounted on the mounting base, and the two second racks are respectively located on opposite sides of the second gear. The third driver is fixedly mounted on the mounting base and is connected to the second gear. The third driver is used to drive the second gear to rotate relative to the mounting base.

[0026] As a preferred technical solution, the high-voltage line connector overheating defect treatment device further includes: a lifting ring, which is fixedly mounted on the top of the support.

[0027] The high-voltage line connector overheating defect treatment device provided by the above technical solution has the following advantages compared with the prior art:

[0028] The controller controls the sliding assembly to move the entire device along the X-axis, allowing it to quickly reach the heating point on the high-voltage line. The controller then controls two clamping parts to clamp the high-voltage line on both sides of the heating point, diverting the current from the high-voltage line through the clamping parts into the wire, thus creating a current bypass and reducing the current flowing through the high-voltage line and the heat at the heating defect. During the clamping process, a temperature sensor monitors the temperature of the high-voltage line at the device's location in real time. Changes in temperature data determine whether the bypass is active, and adjustments are made promptly to ensure effective clamping. This allows for quick and safe temporary elimination of the heating defect, providing a buffer time for subsequent comprehensive repairs. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] In the description of this application, it should be understood that the terms "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] Please see Figures 1-2 This application provides a device for treating overheating defects in high-voltage line connectors. The device includes: a support 1, which is an insulating component; a sliding assembly 2, mounted on the support 1 for slidingly connecting the support 1 to the high-voltage line; and a current-shunting assembly 3, with its two ends connected to the two ends of the support 1 along the X-direction. The current-shunting assembly 3 includes: two clamping parts 31 and a wire 32. The two clamping parts 31 are respectively connected to the two ends of the support 1 along the X-direction, and the two ends of the wire 32 are respectively connected to one of the clamping parts 31. 1. Fixed connection, the clamping part 31 is used to clamp the high-voltage line so that the current on the high-voltage line flows to the wire 32 to form a bypass; temperature sensor 5, the temperature sensor 5 is disposed on the support 1, and is used to monitor the temperature of the high-voltage line; controller, the controller is connected to the sliding assembly 2, the clamping part 31 and the temperature sensor 5 respectively; the controller is configured to: determine the on / off state of the bypass according to the temperature change of the high-voltage line monitored by the temperature sensor 5; wherein, the X direction is the axial direction of the high-voltage line.

[0039] In this embodiment, when overheating is detected at the high-voltage line joint, i.e., a heating defect occurs, the high-voltage line joint heating defect handling device is slidably installed on the high-voltage line via the sliding component 2. The user operates the controller to control the sliding component 2 to quickly move the entire device to the defect location. During the movement, the temperature sensor 5 monitors the temperature of the high-voltage line at the device's location in real time, and determines whether the device has been moved to the heating defect location based on the monitored temperature changes of the high-voltage line. Then, the user operates the controller to tighten the two clamping parts 31, so that the two clamping parts 31 are clamped onto the high-voltage lines on both sides of the defect. This application preferably uses metal parts as clamping parts 31, which have good conductivity, so that the current at the defect location is diverted to the wire 32 through the clamping parts 31, thereby forming a bypass. The bypass wire 32 can divert part of the current, reducing the current flowing through the defect location, thereby reducing its power loss, quickly suppressing temperature rise, preventing the joint from further oxidation, burning, or even breakage due to overheating, and preventing the fault from escalating. Furthermore, after bypassing the current diversion, the defect can be repaired in a "load reduction" or "power outage" state without interrupting the main power supply, maximizing power supply reliability and reducing economic losses and social impact caused by power outages. In addition, the bypass, as a temporary measure, can temporarily stabilize the defect state, buying time to develop detailed repair plans and allocate resources, making repairs more orderly and efficient, and reducing the blindness of emergency repairs. After the bypass is activated, the temperature of the high-voltage line continues to be monitored by temperature sensor 5. If the high-voltage line temperature drops significantly and tends to stabilize, it indicates that the current diversion is effective and the defect is under control. If the temperature continues to rise or fluctuates significantly, it may indicate problems such as loose clamping of clamping part 31 (leading to excessive contact resistance) or insufficient bypass current. Users can adjust the clamping force in a timely manner according to temperature data changes, or remove the device to check the connection of wire 32 to ensure that the bypass system functions as expected.

[0040] In some embodiments, the sliding assembly 2 includes a roller 21 and a first driver (not shown in the figure). The roller 21 has a groove on its outer periphery, and the roller 21 is tactilely connected to the high-voltage line through the groove. The first driver is fixedly mounted on the support 1 and is drively connected to the roller 21. The first driver drives the roller 21 to rotate, thereby driving the support 1 to move along the X direction. The user operates a controller to control the first driver, driving the roller 21 to rotate, thus moving the entire support 1 along the axial direction of the high-voltage line to quickly move the device to the location of the overheating defect.

[0041] In some embodiments, the support 1 includes: a housing 11 and a bracket 12. The bracket 12 is fixedly mounted on the top of the housing 11, and the bottom of the bracket 12 and the top of the housing 11 define a wire-passing space 13 for the high-voltage line to pass through. The first driver is mounted on the bracket 12, and the clamping part 31 is slidably connected to the housing 11. This configuration serves several purposes. First, the housing 11 acts as a base for mounting the clamping part 31, which directly contacts the high-voltage line. Its enclosed structure provides physical protection for internal components, reducing the erosion of core components by external dust, rain, and debris. Second, the housing 11, as a base, has a large bottom area and a certain weight, lowering the overall center of gravity and providing stable support for the bracket 12 and upper components. This reduces the swaying of the support 1, especially when the high-voltage line is under tension or affected by the external environment, thus improving the overall anti-overturning capability. On the other hand, the bracket 12 is located at the top of the housing 11, which is suitable for installing components such as the sliding component 2 that require a certain height and involve action execution, avoiding interference with the high-voltage cable threading space 13 and the clamping part 31, and making the layout of each component more orderly. In addition, as the upper support structure, the bracket 12 preferably adopts a lightweight frame design, which reduces the overall weight while ensuring strength, balancing stability and economy. Furthermore, the bottom of the bracket 12 and the top of the housing 11 define the threading space 13, and the channel for the high-voltage cable to pass through can be formed by utilizing the structural gap between the two, without the need for additional complex components, simplifying the design of the threading structure; and this space is defined by the rigid housing 11 and the edge of the bracket 12, which can play a certain guiding and limiting role for the high-voltage cable, preventing the cable from shaking or deviating at will, and ensuring its stable force under the action of the clamping part 31.

[0042] In some embodiments, the clamping part 31 is slidably connected to the housing 11 to adjust the relative distance between the two clamping parts 31, thereby improving the applicability of the device. See also... Figures 1-3In some embodiments, the housing 11 has an internal cavity, and the housing 11 has a through hole on each side along the X direction, with the two through holes communicating with the cavity. The high-voltage line connector overheating defect treatment device further includes a distance adjustment component 4, which includes a first gear 41, two first racks 42, and a second driver 43. The first gear 41 is located in the cavity, and the two first racks 42 are located on opposite sides of the first gear 41. The second driver 43 is fixedly installed in the housing 11 and is connected to the first gear 41. The second driver 43 is used to drive the first gear 41 to rotate. One end of each first rack 42 is fixedly connected to a clamping part 31, and the other end extends along the X direction and passes through a through hole to mesh with the first gear 41. The second driver 43 is signal-connected to the controller. According to the range of the overheating defect, the user can operate the controller to control the second driver 43, drive the first gear 41 to rotate, and drive the two first racks 42 to move closer or further apart, so that the two clamping parts 31 located on both sides of the housing 11 move closer or further apart, and adjust the distance between the two clamping parts 31 accordingly to better clamp the high voltage lines on both sides of the defect, thereby improving the applicability of the device.

[0043] Please see Figure 4 In some embodiments, the clamping part 31 includes: a mounting base 311, a gripper 312, a drive mechanism 313, and an electrical connector 314. The mounting base 311 is connected to the housing 11. The gripper 312 is disposed at the top of the mounting base 311. The drive mechanism 313 is disposed on the mounting base 311 and is used to drive the gripper 312 to open or close. The electrical connector 314 is fixedly connected to the mounting base 311. The wire 32 is fixedly connected to the electrical connector 314. The drive mechanism 313 is signal-connected to the controller.

[0044] In this embodiment, when the gripper 312 tightens to hold the high-voltage wire, the gripper 312 can form a tight electrical contact with the high-voltage wire, and the current can be conducted to the mounting base 311 through the gripper 312. The electrical connector 314 is fixed on the mounting base 311, and the wire 32 is connected to the mounting base 311 through the electrical connector 314, thereby forming a complete current path of "high-voltage wire → gripper 312 → mounting base 311 → electrical connector 314 → wire 32", realizing bypass current diversion and avoiding problems such as increased resistance and heat generation caused by poor contact, thus ensuring the stability of current conduction. In addition, the mounting base 311, as a basic carrier, not only connects the housing 11, but also integrates the gripper 312, the drive mechanism 313, and the electrical connector 314, making each component form a compact functional unit, reducing structural redundancy and improving overall stability. At the same time, the rigid structure of the mounting base 311 can provide a stable mounting reference for the drive mechanism 313, avoiding deviation of the gripper 312's movement due to deformation of the mounting base 311 during the drive process, further ensuring clamping accuracy. In addition, this application preferably adopts a plug-in design to connect the wire 32 to the electrical connector 314, which can ensure a firm electrical connection between the wire 32 and the mounting base 311 and avoid loosening of the contact due to vibration or external force.

[0045] Please see Figure 5 In some embodiments, the inner peripheral wall of the mounting base 311 is provided with sliding grooves 3111 on opposite sides. The gripper 312 includes two gripper bodies 3121. The drive mechanism 313 includes a second gear 3131, two second racks 3132, and a third driver (not shown in the figure). The second gear 3131 is disposed on the mounting base 311, and the two second racks 3132 are respectively disposed on opposite sides of the second gear 3131. The third driver is fixedly mounted on the mounting base 311 and is connected to the second gear 3131 for transmission. The third driver is used to drive the second gear 3131 to rotate relative to the mounting base 311. The two second racks 3132 are slidably disposed in each of the sliding grooves 3111, and one end of each second rack 3132 is fixedly connected to a gripper body 3121, and the other end extends along the Y direction and meshes with the second gear 3131. The Y direction is the radial direction of the high-voltage line, and the Y direction is perpendicular to the X direction.

[0046] In this embodiment, the two second racks 3132 mesh with the same second gear 3131, and the racks extend in opposite directions. When the third driver drives the second gear 3131 to rotate, the rotational motion of the gear is converted into linear motion of the two second racks 3132 through meshing, and the two second racks 3132 inevitably move in opposite directions. This design ensures that the two claws 3121 open or close synchronously, avoiding clamping offset caused by asynchronous movements on both sides, and ensuring stable conductive contact. In addition, the second racks 3132 extend linearly along the Y direction, and their movement trajectory is consistent with the opening and closing direction of the grippers 312, eliminating the need for a complex steering transmission structure, simplifying the internal spatial layout of the mounting base 311, and making the entire clamping part 31 more compact.

[0047] In some embodiments, the electrical connector 314 is an aviation-grade sealed electrical connector. Aviation-grade sealed electrical connectors typically employ rubber sealing rings and metal sealing surfaces to achieve a high level of protection. In outdoor high-voltage line operation scenarios, facing environmental factors such as rain, fog, dust, and condensation, the sealing performance effectively prevents moisture and contaminants from entering the connector's interior. Furthermore, aviation-grade sealed electrical connectors have stable conductivity, ensuring efficient bypass current diversion, precisely reducing the load on the original heating connector, and achieving defect control goals.

[0048] In some embodiments, the high-voltage line connector overheating defect treatment device further includes a camera 6, which is mounted on the support 1 and is signal-connected to the controller. When connecting the device to the high-voltage line, the location of the device can be determined through the image information fed back by the camera 6, improving installation efficiency and preventing improper installation that could lead to safety accidents such as the device falling off during use.

[0049] In some embodiments, the high-voltage line connector overheating defect treatment device further includes a lifting ring 7, which is fixedly mounted on the top of the support 1. The lifting ring 7 serves as a connection fulcrum for the insulating rod, allowing operators to suspend the device from a safe distance using the insulating rod. This eliminates the need for contact with the high-voltage line or the equipment itself, completely isolating the high-voltage hazard source from the operational process and improving the device's safety. Furthermore, the lifting ring 7, fixed to the top of the support 1, is positioned above the device's center of gravity, ensuring balanced force distribution throughout the device during suspension and preventing tilting or swaying.

[0050] In summary, the high-voltage line joint overheating defect treatment device provided in this embodiment can quickly establish a current bypass for current diversion when an overheating defect occurs in the high-voltage line joint, effectively reducing the heating temperature and temporarily eliminating the defect. Furthermore, by monitoring the temperature of the high-voltage line using a temperature sensor, the continuity of the bypass can be effectively monitored, ensuring the stability of the bypass connection. The device has a simple overall structure, is easy to install, and quick to operate, providing ample buffer time for subsequent comprehensive maintenance.
