Technical Field

[0001] This application relates to the field of power distribution cable maintenance technology, and in particular to a power distribution cable testing device. Background Technology

[0002] Power distribution cables are used for power transmission and are an integral part of the power system. The operating status of power distribution cables affects the stability and security of the power grid. Under high-voltage or ultra-high-voltage environments, power distribution cables may experience partial discharge due to long-term exposure to electric field stress, mechanical stress, or environmental factors (such as humidity and temperature changes).

[0003] In related technologies, detection components (such as sensors) are fixedly installed at the joints of power distribution cables to monitor the discharge status at the joints.

[0004] However, the aforementioned detection device is fixed in place and cannot be moved, so it can only detect partial discharge near the connector, resulting in a small detection range. Summary of the Invention

[0032] Power distribution cables are used for power transmission and are an integral part of the power system. The operating status of power distribution cables affects the stability and security of the power grid. Under high-voltage or ultra-high-voltage environments, power distribution cables may experience partial discharge due to long-term exposure to electric field stress, mechanical stress, or environmental factors (such as humidity and temperature changes).

[0033] In related technologies, detection components (such as sensors) are fixedly installed at the joints of power distribution cables to monitor the discharge status at the joints.

[0034] However, the aforementioned detection device is fixed and cannot be moved. It can only detect partial discharge near the connector, and the detection range is small, which cannot cover other locations of the power distribution cable.

[0035] In view of this, this application provides a power distribution cable testing device, comprising: a testing component, the testing component including a testing body, a first moving member, and a testing element. The testing body is sleeved on the power distribution cable, and the first moving member is disposed on the testing body. The first moving member is movably connected to the power distribution cable and moves along the power distribution cable, thereby causing the testing body to move relative to the power distribution cable. The testing body is disposed on the testing body, and the testing element is used to detect the discharge current and surface condition of the power distribution cable. This application, by having the testing body sleeved on the power distribution cable and integrating the first moving member and the testing element on the testing body, allows the first moving member to move relative to the surface of the power distribution cable when it moves along the power distribution cable. This transforms the testing element from a fixed installation to a movable one, expanding its testing range from a fixed position (such as the joint of the power distribution cable) to any position on the power distribution cable that the first moving member can reach, thus increasing the testing range of the power distribution cable.

[0036] Furthermore, the detection element 130 is used to detect the status of the power distribution cable, including but not limited to the discharge current of the power distribution cable and the image status of the outer surface of the power distribution cable.

[0037] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0038] This application provides a power distribution cable 10 detection device, combined with... Figure 1 , Figure 2 , Figure 3 , Figure 4The system includes a detection component 100, which comprises a detection body 110, a first moving member 120, and a detection member 130. The detection body 110 is sleeved on the power distribution cable 10. The first moving member 120 is provided on the detection body 110 and is movably connected to the power distribution cable 10. The first moving member 120 moves along the power distribution cable 10 so that the detection body 110 moves relative to the power distribution cable 10. The detection member 130 is provided on the detection body 110 and is used to detect the discharge current and surface condition of the power distribution cable 10.

[0039] The detection body 110 is fitted onto the power distribution cable 10. Specifically, the detection body 110 is an openable ring structure formed by two semi-annular shells connected by hinges or locking buckles, so as to be easily assembled onto the laid power distribution cable 10 on site. The detection body 110 can also be a complete annular shell. When installing the power distribution cable 10, the power distribution cable 10 passes through the detection body 110, so that the detection body 110 is fitted onto the power distribution cable 10.

[0040] The first moving member 120 is movably connected to the power distribution cable 10. The detection body 110 is provided with at least one transmission groove 101 for mounting the first moving member 120. The first moving member 120 is a drive wheel, rotatably mounted in the transmission groove 101 via an axle and bearings. The outer circumferential surface of the drive wheel contacts the outer surface of the power distribution cable 10. The drive wheel is driven by a motor installed in the detection body 110 via gear or belt transmission. When the first moving member 120 moves along the power distribution cable 10, it causes the detection body 110 to move relative to the power distribution cable 10. The detection element 130 is used to detect the discharge current of the power distribution cable 10 during the movement.

[0041] The transmission groove 101 is a groove formed on the inner wall of the detection body 110. Its shape matches the wheel axle support of the drive wheel, and the support is fixed in the groove by fasteners.

[0042] For example, the detection body 110 is provided with four transmission grooves 101, and four first moving parts 120 are connected to the four transmission grooves 101 in a one-to-one correspondence. The first moving parts 120 include drive wheels or moving rollers. The drive wheels rotate to drive the entire detection body 110 to move along the outside of the power distribution cable 10.

[0043] The detection body 110 is annular and has a connection hole through which the power cable 10 passes. In some embodiments, the detection body 110 is a detection cover. The detection cover is made of insulating material and has an internal cavity for installing electrical components and a wiring channel.

[0044] The first moving component 120 drives the detection body 110 to move, so that the detection component 130 fixed on the body can detect different sections of the power distribution cable.

[0045] In some embodiments, the detection element 130 may also include an optical recognition module to record and photograph the location and external structural status of the power distribution cable 10, and transmit the image information to a remote monitoring terminal.

[0046] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment further includes a guide rail 140, an adjustment frame 150, and a second moving member 160. The guide rail 140 is disposed within the detection body 110 and is arranged around the extension direction of the power distribution cable 10. The adjustment frame 150 is slidably connected to the guide rail 140. The second moving member 160 and the detection member 130 are both disposed on the adjustment frame 150. The second moving member 160 is used to drive the adjustment frame 150 to move along the guide rail 140 so that the detection member 130 rotates relative to the power distribution cable 10.

[0047] In some embodiments, the adjusting frame 150 is an annular frame, with grooves or sliders on its inner or outer sides that mate with the annular guide rail 140. The second moving member 160 is an electrically driven wheel mounted on the adjusting frame 150, driven by a drive motor to move the adjusting frame 150 around the guide rail 140. Furthermore, the adjusting frame 150 is also provided with a guide wheel 170, which provides support and guidance.

[0048] In other embodiments, the second moving member 160 includes a second drive motor and a drive gear, the drive gear being mounted on the output shaft of the second drive motor; the inner or outer side of the guide rail 140 is provided with an annular rack that meshes with the drive gear. The drive motor drives the gear to rotate, and the gear meshes with the rack, thereby driving the adjusting frame 150 to move around the guide rail 140.

[0049] The detection element 130 rotates relative to the power distribution cable 10 around the extension direction of the power distribution cable 10 via the second moving element 160, thereby detecting one revolution of the power distribution cable 10. The cooperation between the first moving element 120 and the second moving element 160 enables the detection element 130 to move along the power distribution cable 10 while rotating around the circumference of the power distribution cable 10.

[0050] The second moving component 160 drives the adjusting frame 150 to move along the guide rail 140, thereby causing the detection component 130 to rotate relative to the power distribution cable 10 to detect one revolution of the power distribution cable 10. The first moving component 120 drives the detection body 110 to move axially along the cable, and the second moving component 160 drives the detection component 130 to rotate circumferentially around the cable. The two components work together to enable the detection component 130 to move along the power distribution cable 10 while rotating around the circumference of the power distribution cable 10. For example, through this combined motion of axial movement and circumferential rotation, the detection component 130 forms a spiral trajectory along the cable surface, achieving comprehensive detection of the power distribution cable 10 and reducing blind spots.

[0051] In some embodiments, the guide rail 140 is an embedded annular guide rail 140 formed on the inner side of the outer detection cover. The adjustment frame 150 is an annular adjustment frame 150 slidably fitted within the guide rail 140.

[0052] In some embodiments, the second moving member 160 is an electric drive wheel mounted on the adjustment frame 150, which moves the adjustment frame 150 relative to the guide rail 140.

[0053] The detection component 130, such as the optical recognition module, is installed on the adjustment frame 150 and rotates around the cable to achieve all-round detection of the outer circumference of the cable.

[0054] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment further includes a guide wheel 170, guide seats 180 are provided at both ends of the adjustment frame 150, the guide wheel 170 is disposed between the two guide seats 180, and the second moving member 160 and the detection member 130 are respectively disposed in the guide seats 180.

[0055] The guide wheel 170 rolls in contact with the guide rail 140, providing support and guidance for the sliding of the adjusting frame 150, ensuring its smooth operation. The second moving part 160 and the detection part 130 are respectively located at both ends of the adjusting frame 150, separating the driving function and the detection function, resulting in a reasonable layout. The guide seat 180 is an arc-shaped guide seat 180.

[0056] The detection element 130 includes a first detection element 131 and a second detection element 132. The first detection element 131 is used to detect the outer surface condition of the power distribution cable 10, and the second detection element 132 is used to detect the discharge current of the power distribution cable 10. The first detection element 131 and the second detection element 132 are located between two guide seats 180, and the second detection element 132 is located between the guide wheel 170 and the second moving part 160.

[0057] The second detection element 132 is disposed on the adjustment frame 150 and located between the guide wheel 170 and the second moving element 160. A mounting box is provided at the mounting position of the second detection element 132, and the mounting box is used to house the second detection element 132. The second detection element 132 is an ultrasonic sensor, an ultra-high frequency sensor, or a high frequency current transformer. The first detection element 131 is an optical recognition module.

[0058] It should be noted that ultrasonic sensors, ultra-high frequency sensors, high frequency current transformers, or optical recognition modules can all utilize known existing technologies and can be purchased directly. For example, an optical recognition module includes a position sensor and an optical sensor, used to record and photograph the location and external surface condition of power distribution cables, and send the image information to a remote monitoring terminal.

[0059] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment includes a detection component 100 further comprising a heating element 190. A transmission groove 101 is provided on the detection body 110 for mounting a first moving member 120. The heating element 190 is disposed on the detection body 110, and at least a portion of the heating element 190 is located on one side of the transmission groove 101. The heating element 190 is used to heat and dry the first moving member 120.

[0060] The heating element 190 is located on the side of the first moving member 120 away from the power distribution cable 10, thereby keeping it away from the power distribution cable 10 and avoiding damage to the power distribution cable 10. Specifically, the heating element 190 is an electric heating plate or heating rod that is attached to or embedded in the outer wall of the transmission groove 101. The heat generated by the heating element acts on the outer surface of the drive wheel through heat conduction or radiation to prevent condensation or icing on its surface.

[0061] The heating element 190 is used to heat the first moving part 120 to prevent condensation or ice formation on the surface of the first moving part 120 in humid or low-temperature environments, and to ensure the friction between the first moving part 120 and the surface of the power distribution cable.

[0062] For example, the heating element 190 is an arc-shaped electric heating strip, and the moving element is a drive wheel. The arc-shaped electric heating strip is heated by power-on, which can heat and dry the drive wheel, thereby preventing the drive wheel from slipping when rotating on the surface of the power distribution cable 10 and improving the moving efficiency.

[0063] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment further includes an installation component 200. The installation component 200 includes a fixing member 210, a winding drum 220, and a detection cable 230. The winding drum 220 is disposed on the fixing member 210, and the detection cable 230 is wound on the winding drum 220. The winding drum 220 is used to wind up or unwind the detection cable 230, and the detection cable 230 is electrically connected to the detection member 130.

[0064] The mounting bracket 210 is mounted on the equipment's mounting frame. For example, the mounting bracket 210 is connected to a cable mounting tower or bracket via bolts.

[0065] When the detection body 110 is far away from the take-up drum 220 or the fixing member 210, the take-up drum 220 releases the detection cable 230; when the detection body 110 is close to the take-up drum 220 or the fixing member 210, the take-up drum 220 takes up the detection cable 230.

[0066] The detection cable 230 is electrically connected to the detection component 130. One end of the detection cable 230 is electrically connected to the external control unit, and the other end is led out from the take-up drum 220, passes through the cable guide hole on the fixing component 210, extends to the detection body 110, and enters the wiring channel inside the detection body 110 to connect with the connecting ring 111.

[0067] In some embodiments, the fastener 210 is a fixed frame and a lateral assembly frame 212 fixed on the cable installation tower. An external storage box 211 is installed on the upper end of the lateral assembly frame 212, and the winding drum 220 is assembled inside the external storage box 211.

[0068] In some embodiments, the fixing member 210 is disposed on the mounting side wall of the device. A top-mounted adjusting motor 240 is fixed to the upper end of the external storage box 211 to drive the winding drum 220 to rotate, thereby realizing the automatic winding and unwinding of the cable. This allows the detection body 110 to perform long-distance mobile detection, while the cable can be wound and unwound in an orderly manner to avoid tangling.

[0069] In some embodiments, a top-mounted adjusting motor 240 for controlling the rotation of the take-up drum 220 is fixedly mounted on the upper end of the external storage box 211. The top-mounted adjusting motor 240 meshes with the annular tooth groove on the inner arc surface of the take-up drum 220 through gears, thereby realizing the transmission of driving force.

[0070] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment has a connecting ring 111 on the detection body 110, and the connecting ring 111 is electrically connected to the detection cable 230.

[0071] For example, the connecting ring 111 is a conductive metal ring fixedly embedded in the annular groove on the inner wall of the detection body 110, and it is welded or crimped to the core wire of the detection cable 230 passing through the detection body 110 via a wire.

[0072] In some embodiments, the connecting ring 111 is an inner metal ring fixed to the inner wall of the embedded annular guide rail 140 and is connected to the detection cable.

[0073] The embodiments of this application do not limit the number of connecting rings 111. For example, there are two connecting rings 111, and the two connecting rings 111 correspond one-to-one with the two guide seats 180.

[0074] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment is further provided with an elastic contact piece 112 on the detection body 110. The elastic contact piece 112, such as a metal contact piece, is used to press the detection cable 230 against the connecting ring 111.

[0075] In some embodiments, the elastic contact piece 112 is a copper alloy spring piece, one end of which is fixed on the adjustment frame 150 or the guide seat 180, and the other end has an arc-shaped contact. For example, one end of the elastic contact piece is fixed in a preset mounting groove on the adjustment frame 150 or the guide seat 180 by a screw or a snap-fit ​​structure. The spring piece makes its arc-shaped contact always pressed against the ring surface of the fixed connecting ring 111 through its own elastic deformation, forming a sliding electrical connection.

[0076] For example, in order to ensure the stability of electrical conductivity and signal transmission during rotation, a curved elastic contact piece 112 is elastically fitted on the inner side of the adjustment frame 150 to cooperate with the inner connecting ring 111, such as a metal ring.

[0077] When the adjustment frame 150 and other components rotate relative to the detection body 110, the elastic contact piece 112 always maintains sliding contact with the fixed connecting ring 111 under the action of elastic force.

[0078] This application utilizes a built-in metal ring and metal contact piece to ensure that the power supplied by the solar cell is transmitted to the electric drive wheel and the detection element 130, and then the value detected by the detection element 130 is transmitted outward. It is understood that when the adjustment frame 150 drives the detection element 130 to rotate, the elastic contact piece 112 fixed on the adjustment frame 150 always maintains sliding contact with the fixed connecting ring 111, thereby ensuring the continuity and stability of the electrical connection between the detection cable 230 and the detection element 130, and realizing reliable transmission of electrical energy and detection signals.

[0079] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment further includes a photovoltaic element 280, which is disposed on the fixing member 210 and is used to convert light energy into electrical energy.

[0080] In some embodiments, the photovoltaic element 280 is a solar panel, mounted on the upper end of the lateral mounting frame 212 via a column 213. The photovoltaic element 280 is used to convert light energy into electrical energy, providing operating power to the device and improving its self-sustaining capability.

[0081] In some embodiments, the photovoltaic element 280 can be used in conjunction with an energy storage device such as a battery via wires to ensure continuous power supply during cloudy or rainy weather.

[0082] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment further includes a camera 250, a drive 260, and a transmission 270. The drive 260 is connected to the transmission 270, and the camera 250 is connected to the fixing member 210 through the transmission 270.

[0083] The driving component 260 drives the transmission component 270 to rotate, thereby driving the camera component 250 to rotate, thus expanding the range of motion of the camera component 250.

[0084] In some embodiments, the camera 250 is an electronic camera, the drive 260 is a motor, and the transmission 270 is the bottom column 213 and the electrically controlled worm gear 274 and worm 275 assembly therein.

[0085] In one possible implementation, the power distribution cable 10 detection device provided in this application embodiment includes a transmission component 270 comprising a connecting rod 273, a first connecting rod 271, a second connecting rod 272, a worm gear 274, and a worm 275. The first connecting rod 271 is connected to a fixing component 210, such as by welding or bolting. The worm 275 is connected to the connecting rod 273. The first connecting rod 271 and the second connecting rod 272 are rotatably connected. The camera component 250 is connected to the second connecting rod 272. The worm gear 274 is connected to the second connecting rod 272. The worm 275 is meshed with the worm gear 274. The worm 275 is connected to a driving component 260, which drives the worm 275 to rotate, causing the second connecting rod 272 to rotate relative to the first connecting rod 271. The end of the second connecting rod 272 facing the camera component 250 has a connecting cover 2721, which is used for detachable connection with the camera component 250, for example, via a threaded interface or a snap-fit ​​connection.

[0086] The worm 275 is connected to the connecting rod 273. For example, the shaft end of the worm 275 and the connecting rod 273 are coaxially fixed by a coupling or keyway.

[0087] The first link 271 and the second link 272 are rotatably connected, for example, the first link 271 and the second link 272 are rotatably connected through a rotary joint.

[0088] The worm gear 274 is fixedly sleeved on the rotary joint and is connected to the second connecting rod 272. Alternatively, the second connecting rod 272 is connected to the rotary joint, and the worm gear 274 is sleeved on the second connecting rod 272.

[0089] In some embodiments, the rotary joint can be a rotating shaft, i.e., the first connecting rod 271 and the second connecting rod 272 are hinged through a rotating shaft. The worm gear 274 is fixedly sleeved on the rotating shaft and fixedly connected to the second connecting rod 272, so that the rotation of the worm gear 274 can drive the second connecting rod 272 to swing around the rotating shaft.

[0090] The drive unit 260 drives the worm gear 275 to rotate, which in turn drives the worm wheel 274 meshing with it to rotate, thereby driving the second link 272 to rotate relative to the first link 271, adjusting the shooting angle of the camera unit 250 connected to the second link 272.

[0091] The worm gear 275 is connected to the drive unit 260. For example, the drive unit 260 is a servo motor, and the output shaft of the servo motor is connected to one end of the worm gear 275 through a reducer or coupling.

[0092] In some embodiments, the drive member 260 drives the worm gear 275 to rotate, and through the meshing transmission of the worm wheel 274 and the worm gear 275, the rotational motion is converted into the pitch swing of the second link 272, thereby adjusting the angle of view of the camera so that its shooting range can cover the bottom, sides and top of the power distribution cable 10.
