Description

Technical Field

[0001] The invention relates to the field of electric power technology, and in particular to an online collection alarm module for distribution line loss. Background Art

[0002] Line loss usually refers to the power loss on the transmission line, which can also be called line loss load. The main causes of line loss include aging or damage of line insulation, metering failure, and user theft of electricity. The usual method for detecting line loss is to install energy meters at the beginning and end of the distribution line, measure the energy consumption at the beginning and end of the line respectively, and then compare the energy difference between the beginning and the end to calculate the line loss.

[0003] However, there are usually some problems in the daily use of ordinary technical means for collecting and detecting line loss of distribution lines. With the development of science and technology, technical personnel in related fields have also made a lot of optimizations on the means of collecting and detecting line loss. In order to make a more accurate comparison, a Chinese patent with publication number CN220983408U discloses a line loss detection device, including a support platform, a detection board, a camera and a detection mechanism. When in use, the detection board is fixed on the top of the support platform, and the limit mechanism on the inner side of the limit platform is used to position the line, so that the line moves through the detection board and moves stably inside multiple detection mechanisms, so that the current generated by the leakage of the wire is transmitted to the current sensor through the copper plate, and the signal controller controls the horn and the alarm light to remind the detection personnel.

[0004] However, the above device still has some shortcomings in actual use:

[0005] 1. When the above device is used, one end of the cable to be tested needs to pass through the limit platform and the detection plate in turn, and then the cable therein is limited, and then the limited cable is driven to slide through the limit platform and the detection plate. In this process, the outer side of the cable is recorded by a number of cameras distributed circumferentially on the detection plate, and then the cable is energized to transmit the current generated by the leakage on the cable to the signal controller, and the horn and alarm light are controlled to remind the detection personnel. When using it, the installed cables need to be removed, and then the cables are pulled to slide in the limit platform and the detection plate, and the effect of online collection and detection of the installed cables cannot be achieved.

[0006] 2. The photos of cables taken by the above-mentioned device through several cameras cannot effectively instruct the collectors. After getting the photos, the collectors often need to compare multiple photos one by one to find the location of abnormal cable loss, which is relatively time-consuming and laborious.

[0007] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing technical means for collecting and detecting line losses in distribution lines. Summary of the invention

[0008] In order to solve the above problems, the present invention provides an online distribution line loss collection alarm module, including a collector and an alarm terminal. The collector and the alarm terminal are electrically connected, and the collector is also connected to the terminal device through a communication terminal. The collector is used to collect areas with abnormal line loss on the cable and output a signal to the alarm terminal to remind the collector that the cable loss collected here is abnormal.

[0011] Preferably, one end of the limiting protrusion away from the mounting ring is connected to a guide slider, and a sliding groove matched with the guide slider is provided on the inner side wall of the mounting cavity.

[0013] Preferably, a sliding through groove is formed on the arc-shaped clamping block at a position corresponding to the stop pin, so that when the mounting ring sleeve and the limiting ring sleeve are assembled, the stop pin and the arc-shaped clamping block are also assembled accordingly.

[0014] Preferably, the arc-shaped clamping block is connected to the limiting ring sleeve by a positioning pin.

[0015] Preferably, the clamping member includes a plurality of arc-shaped clamping plates which are circumferentially evenly and symmetrically connected between the mounting ring sleeve and the limiting ring sleeve, a connecting slide rod is provided on the arc-shaped clamping plate, the connecting slide rod passes through the mounting ring sleeve and the limiting ring sleeve correspondingly, a connecting dial plate is provided on the connecting slide rod, and an adjustment spring is provided on the connecting slide rod which is located between the connecting dial plate and the mounting ring sleeve or the connecting dial plate and the limiting ring sleeve.

[0016] Preferably, the two ends of the arc-shaped clamping plate in the length direction are symmetrically connected with mounting frames, and limiting rollers are installed in the mounting frames, and the bottoms of the two limiting rollers on the same arc-shaped clamping plate are arranged beyond the arc surface of the arc-shaped clamping plate.

[0017] Preferably, the warning end includes a sliding groove opened on the opposite side of the arc-shaped clamping plate, and the sliding groove is sequentially limited and connected with electrode sheet one and electrode sheet two. The outer surface of electrode sheet one is connected with a connecting guide rod passing through the arc-shaped clamping plate and inserted in the connecting slide rod. A warning light is circumferentially installed on the mounting ring sleeve or the limiting ring sleeve, and the warning light and the connecting guide rod are electrically connected through an electrical conductor.

[0018] Preferably, the electrode sheet 1 and the electrode sheet 2 on the same arc-shaped clamping plate are arranged at a distance from each other, and a limit slider inserted in a limited position on the arc-shaped clamping plate is symmetrically connected to both sides of the electrode sheet 2.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 To Attachment Fig. 9 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0035] The embodiment of the present application discloses an online distribution line loss collection alarm module, which explains that the online distribution line loss collection alarm module is mainly used in the process of collecting and detecting the line loss of distribution cables, and technically achieves the effect of collecting and detecting the line loss status of distribution cables; especially when collecting data from installed cables, it effectively avoids the need to remove the installed cables and then simulate the power-on state; further, the online distribution line loss collection alarm module also indicates the location of abnormal line loss on the cable, so that the collection personnel can quickly find the location of abnormal cable line loss.

[0036] Example 1: Reference Figure 1 As shown, a distribution line loss online collection alarm module includes a collector 1 and an alarm terminal 2. The collector 1 and the alarm terminal 2 are electrically connected. The collector 1 is also connected to the terminal device through a communication terminal. The communication terminal preferably adopts a GPRS / 4G / 5G module for remote data transmission and connection. The collector 1 is used to collect areas with abnormal line loss on the cable and output signals to the alarm terminal 2 to remind the collector that the cable loss collected here is abnormal.

[0037] Reference Figure 1 and Figure 2 As shown, a collector 1 is used to collect and process signals from abnormal line loss areas on a cable; specifically, the collector 1 includes a mounting ring 10, a limiting ring 11, a limiting piece 12 and a clamping piece 13, the mounting ring 10 and the limiting ring 11 are symmetrically distributed, the mounting ring 10 and the limiting ring 11 are limitedly spliced ​​by the limiting piece 12 to form a complete circular ring, and the mounting ring 10 and the limiting ring 11 are symmetrically connected with a clamping piece 13 for positioning and limiting the cable.

[0038] During specific use, the installation ring 10 and the limiting ring 11 are arranged on both sides of the cable to be processed, and then the two ends of the installation ring 10 and the limiting ring 11 are fitted together to form a situation where the installation ring 10 and the limiting ring 11 clamp the cable in the middle, and then the installation ring 10 and the limiting ring 11 are limitedly installed by the limiting member 12, and at the same time, the cable is clamped and positioned by the clamping member 13 arranged between the installation ring 10 and the limiting ring 11, so that the collector 1 is assembled on the cable to collect and detect it, thereby achieving the effect of online collection and detection of cable line loss.

[0039] If the line loss in the cable collection area is abnormal, the clamping member 13 outputs a signal to the alarm terminal 2 to issue an alarm to remind the collection personnel that the line loss of the cable here is abnormal.

[0040] Reference Figure 3 and Figure 4As shown, a clamping member 13 is used to position and limit the mounting ring sleeve 10 and the limiting ring sleeve 11; specifically, the limiting member 12 includes an extension protrusion 120, a mounting cavity 121, a limiting protrusion 122, a limiting guide rod 123 and a contraction spring 124. The extension protrusions 120 are symmetrically connected at both ends of the mounting ring sleeve 10, and a mounting cavity 121 corresponding to the extension protrusion 120 is formed on the limiting ring sleeve 11. The limiting protrusion 122 for limiting the extension protrusion 120 is also connected in the mounting cavity 121. A limiting guide rod 123 is passed through the limiting protrusion 122, and a contraction spring 124 is sleeved on the limiting guide rod 123 and located between the limiting protrusion 122 and the mounting cavity 121.

[0041] When in use, the installation ring sleeve 10 and the limiting ring sleeve 11 are correspondingly arranged on both sides of the cable to be collected, and then the installation ring sleeve 10 and the limiting ring sleeve 11 are slid in the direction close to each other, and the installation ring sleeve 10 and the limiting ring sleeve 11 move to drive the extension protrusion 120 to be inserted into the installation cavity 121, and at the same time, the limiting protrusion 122 slides in the direction away from the extension protrusion 120 and against the inner side wall of the installation cavity 121, and the limiting protrusion 122 moves to drive the connected limiting guide rod 123 to slide synchronously, and causes the connected contraction spring 124 to be stretched. After one end of the extension protrusion 120 is inserted into the installation cavity 121, the contraction spring 124 contracts, driving the connected limiting protrusion 122 and the limiting guide rod 123 to slide in the direction close to the extension protrusion 120, and under the drive of the connected contraction spring 124, they always contact the extension protrusion 120, so as to achieve the effect of limiting the extension protrusion 120.

[0042] Furthermore, an extension block having a triangular structure is connected to the extension protrusion 120 and the limiting protrusion 122, and the inclined surfaces of the two extension blocks are arranged opposite to each other. When in use, after the extension protrusion 120 drives the extension block connected thereto to be inserted into the installation cavity 121, the extension block drives the limiting protrusion 122 and the connected extension block to slide in a direction away from the extension protrusion 120 along the inclined surface of the extension block on the limiting protrusion 122, and drives the connected contraction block to slide. The spring 124 stretches inside, and then continues to drive the extension protrusion 120 and the connected extension block to go deep into the installation cavity 121. After driving the extension protrusion 120 and the connected extension block to pass over the extension block on the limiting protrusion 122, the limiting protrusion 122 and the connected extension block are driven to contact the extension protrusion 120 under the reset and contraction of the contraction spring 124, so as to automatically limit the installation ring sleeve 10 and the limiting ring sleeve 11 when they are assembled.

[0043] Reference Figure 3 and Figure 4As shown, the end of the limiting convex rod 122 away from the mounting ring sleeve 10 is connected to a guide slider 125, and a sliding groove 1250 adapted to the guide slider 125 is provided on the inner side wall of the mounting cavity 121. When in use, when the limiting convex rod 122 slides in the mounting cavity 121, it also drives the connected guide slider 125 to slide axially in the sliding groove 1250. While the sliding direction of the connected limiting convex rod 122 is limited by the guide slider 125, it also prevents the limiting convex rod 122 from rotating during sliding, and drives the connected extension block to rotate and deviate, so that it is difficult to limit the extension convex rod 120.

[0044] Further, refer to Figure 3 and Figure 4 As shown, by driving the contraction spring 124 to undergo elastic deformation, the restoring elastic force of the contraction spring 124 drives the connected limiting protrusion 122 and the extension block to limit the extension protrusion 120, and the restoring elastic force of the contraction spring 124 is easily affected by the deviation of the limiting protrusion 122 and the two extension blocks on the extension protrusion 120, resulting in a poor limiting effect on the extension protrusion 120, thereby causing the mounting ring sleeve 10 and the limiting ring sleeve 11 to be easily opened by external interference after assembly. Based on this, a stop pin 126 for limiting the limiting protrusion 122 is inserted on the mounting ring sleeve 10, and the stop pin 126 is coaxially arranged with the limiting guide rod 123 and extends outward from the connected mounting ring sleeve 10, and an arc-shaped block 1260 for limiting the stop pin 126 is arranged at one end of the stop pin 126 passing through the mounting ring sleeve 10, and the arc-shaped block 1260 is connected to the limiting ring sleeve 11.

[0045] When in use, when the extension protrusion 120 is inserted into the installation cavity 121, the limiting protrusion 122 is pushed to slide in the direction away from the extension protrusion 120. After the limiting protrusion 122 moves, it pushes the stop pin 126 to slide in the direction of sliding out of the installation cavity 121. After the limiting protrusion 122 is driven by the connected contraction spring 124 to contact the extension protrusion 120, the arc block 122 slides in the direction close to the stop pin 126. 260, after the arc-shaped clamping block 1260 contacts the stop pin 126, the stop pin 126 is driven to move downward and reset, and then reset in the direction of going deeper into the installation cavity 121 until it contacts the limiting protrusion 122. At this time, the arc-shaped clamping block 1260 limits the stop pin 126, and the stop pin 126 limits the limiting protrusion 122, which effectively avoids the problem of the installation ring sleeve 10 and the limiting ring sleeve 11 being easily opened due to external interference after assembly.

[0046] Reference Figure 4As shown, a sliding groove 1261 is formed on the arc-shaped clamping block 1260 at a position corresponding to the stop pin 126, so that when the mounting ring sleeve 10 and the limiting ring sleeve 11 are assembled, the stop pin 126 and the arc-shaped clamping block 1260 are also assembled accordingly.

[0047] Reference Figure 4 As shown, the arc block 1260 is connected to the limiting ring sleeve 11 through the positioning pin 127. After the stop pin 126 is limited by the arc block 1260, the arc block 1260 is correspondingly limited on the limiting ring sleeve 11 through the positioning pin 127.

[0048] Reference Figures 2 to 6 As shown, a clamping member 13 is used to position and limit the cable; specifically, the clamping member 13 includes an arc-shaped clamping plate 130, a connecting slide rod 131, a connecting plate 132 and a clamping spring 133. A plurality of arc-shaped clamping plates 130 are evenly and symmetrically connected between the mounting ring sleeve 10 and the limiting ring sleeve 11. A connecting slide rod 131 is arranged on the arc-shaped clamping plate 130. The connecting slide rod 131 passes through the mounting ring sleeve 10 and the limiting ring sleeve 11 accordingly. A connecting plate 132 is sleeved on the connecting slide rod 131. A clamping spring 133 is sleeved on the connecting slide rod 131 and is located between the connecting plate 132 and the mounting ring sleeve 10 or the connecting plate 132 and the limiting ring sleeve 11.

[0049] When in use, after the mounting ring sleeve 10 and the limiting ring sleeve 11 are correspondingly fitted together, after the cable contacts the several arc-shaped clamping plates 130 between the mounting ring sleeve 10 and the limiting ring sleeve 11, the arc-shaped clamping plates 130 are driven to slide in the direction away from the cable, and the sliding of the arc-shaped clamping plates 130 drives the connected connecting slide rods 131 and connecting dial plates 132 to slide, and the sliding of the connecting dial plates 132 drives the connected clamping springs 133 to be stretched. After the clamping springs 133 are stretched, they need to be restored to a normal extended state. Therefore, under the reset drive of the connected clamping springs 133, the connected connecting dial plates 132, the connecting slide rods 131 and the arc-shaped clamping plates 130 are driven to slide in the direction close to the cable until the arc-shaped clamping plates 130 are in contact with the outer side of the cable. After all the arc-shaped clamping plates 130 are in contact with the cable at the same time, the effect of self-centering and limiting the cable according to the size of the cable is completed.

[0050] Furthermore, a connecting bar 134 is symmetrically arranged at any one end of the mounting ring sleeve 10 and the limiting ring sleeve 11, and at least two half ring sleeves 135 are symmetrically arranged at one end of the connecting bar 134 away from the mounting ring sleeve 10 and the limiting ring sleeve 11. The two half ring sleeves 135 are also spliced ​​to form a complete circular ring sleeve, and the circular ring sleeve formed by splicing the mounting ring sleeve 10 and the limiting ring sleeve 11 is coaxially arranged, and a plurality of wiping plates 136 are symmetrically connected to the inner side of the two half ring sleeves 135 in a circumferential and symmetrical manner. A plurality of bristles are arranged on the wiping plates 136, and a sliding guide rod 137 that slides through the half ring sleeve 135 is connected to the outer side of the wiping plate 136, and the sliding guide rod 137 is connected to the connecting slide rod 131 through a connecting plate 132.

[0051] By installing the ring sleeve 10, the limiting ring sleeve 11 and the two circular ring sleeves formed by splicing the two half ring sleeves 135, it is possible to effectively keep a section of the cable between the two circular ring sleeves in a straight state when the device slides on the cable, and by wiping the outer side of the cable with the wiping plate 136, it is possible to prevent impurities attached to the outer side of the cable from affecting the collection results, thereby ensuring the accuracy of the collection results.

[0052] Reference Figure 5 As shown, the two ends of the arc clamping plate 130 in the length direction are symmetrically connected with the installation frame 14, and the limiting rollers 140 are rotatably installed in the installation frame 14, and the bottoms of the two limiting rollers 140 on the same arc clamping plate 130 exceed the arc surface of the arc clamping plate 130. When in use, when the installation ring 10 and the limiting ring 11 are correspondingly attached to the outside of the cable, the limiting rollers 140 at both ends of the arc clamping plate 130 first contact the outer side of the cable to pre-position the cable, and after the cable contacts the limiting rollers 140, the arc clamping plate 130 is driven by the limiting rollers 140 to slide away from the cable, thereby driving the clamping spring 133 to be stretched, and when the limiting rollers 140 abut against the outer side of the cable, a gap is left between the cable and the arc clamping plate 130, and when the device is driven to slide on the cable, the friction on the cable is reduced by the rotation of the rollers to avoid additional consumption of the insulation layer on the cable.

[0053] As an optional implementation, the limiting roller 140 may also be arranged in plurality in the circumferential direction relative to the arc length of the arc clamping plate 130 , thereby increasing the contact area between the limiting roller 140 and the cable to avoid direct contact between the cable and the arc clamping plate 130 .

[0054] Reference Figure 4As shown, the warning terminal 2 is used to remind the collector that the collected cable loss is abnormal; specifically, the warning terminal 2 includes a sliding groove 20, an electrode piece 1 21, an electrode piece 22, a warning light 23 and a connecting guide rod 24. The sliding groove 20 is opened on the opposite side of the arc-shaped clamping plate 130, and the electrode piece 1 21 and the electrode piece 22 are sequentially limitedly connected in the sliding groove 20. The outer surface of the electrode piece 1 21 is connected to a connecting guide rod 24 that passes through the arc-shaped clamping plate 130 and is inserted into the connecting slide rod 131. A warning light 23 is circumferentially installed on the mounting ring sleeve 10 or the limiting ring sleeve 11, and the warning light 23 is electrically connected to the connecting guide rod 24 through an electric conductor.

[0055] Further, refer to Figures 6 to 8 As shown, the electrode sheet 1 21 and the electrode sheet 2 22 on the same arc-shaped clamping plate 130 are arranged at a distance, and at least two electrode sheets 1 21 are arranged, and the two electrode sheets 1 21 are symmetrically distributed on both sides of the electrode sheet 22, and the limiting sliders 25 inserted in a limited position on the arc-shaped clamping plate 130 are symmetrically connected on both sides of the electrode sheet 22. The limiting sliders 25 are set with magnetic materials or materials that allow magnetic adsorption. The electrode sheet 22 is also connected to a driven slide 250, and the driven slide 250 penetrates the electrode sheet 22 and the two electrode sheets 1 21 at the same time, and is slidably connected to the two electrode sheets 1 21. The driven slide 250 is sleeved with a reset spring 251 located in the connecting slide 131.

[0056] In the initial state, the normal magnetic field generated by the current passing through the cable with normal line loss during use will also generate a certain adsorption force on the limit slider 25, thereby causing the connected reset spring 251 to be stretched a certain distance.

[0057] When in use, after the installation ring 10 and the limit ring 11 are correspondingly assembled on a certain section of the cable, if the line loss of the cable here is abnormal, the abnormal cable line loss will cause the operating current of the cable here to be abnormal, and when the current on the cable is higher or lower than the normal working range, it will cause the magnetic field at the abnormal cable line loss to be disordered, thereby causing the adsorption force on the limit slider 25 to increase or weaken. Driven by the connected reset spring 251, when the adsorption force of the cable magnetic field on the limit slider 25 is weakened, the reset spring 251 drives the connected driven slide bar 250, electrode sheet 22 and limit slider 25 to shrink in the direction away from the cable, so that the electrode sheet 22 contacts one of the electrode sheets 1 21 away from the cable, and then a closed circuit is formed between the electrode sheet 1 21, the electrode sheet 22, the connecting guide rod 24 and the warning light 23, so that the warning light 23 lights up to warn the collector.

[0058] When the adsorption force of the cable magnetic field on the limit slider 25 increases, the limit slider 25 is slid toward the direction close to the cable, and drives the reset spring 251 to be further stretched. At this time, the limit slider 25 moves to drive the connected electrode sheet 2 22 to approach and fit with one of the electrode sheets 22 close to the cable, and then a closed circuit is formed between the electrode sheet 1 21, the electrode sheet 22, the connecting guide rod 24 and the warning light 23, so that the warning light 23 lights up to warn the collector.

[0059] It should be noted that, under normal circumstances, abnormal cable line loss will cause the resistance of the cable to increase. In order to maintain the same power transmission, the current passing through the cable will also increase, and the change in current will change the strength of the magnetic field. At the same time, abnormal cable line loss will also cause local overheating of the cable. This uneven temperature distribution will also produce an uneven magnetic field around the cable. Long-term high temperature will also cause damage to the insulation layer on the cable.

[0060] Based on this, a thermal sensor or a camera lens may be connected to the arc-shaped clamping plate 130 to further observe the surface of the cable loss area in detail, so as to improve the accuracy of collecting abnormal cable loss areas.

[0061] Example 2: Reference Figures 6 to 9 As shown, on the basis of the first embodiment, in order to facilitate the warning light 23 to warn the collection personnel, the collection personnel can easily identify the abnormal position of the line loss on the cable; therefore, an indicator 3 for indicating the position of the line loss on the cable is also provided on the connecting slide bar 131, specifically, the indicator 3 includes a flexible positioning plate 30, an arc-shaped protrusion 31 and a deformation section 32, and the flexible positioning plate 30 is detachably installed on the side of the arc-shaped clamping plate 130 away from the connecting slide bar 131, and the driven slide bar 250 slides through the flexible positioning plate 30, and at least two arc-shaped protrusions 31 are sleeved on the driven slide bar 250, and the two arc-shaped protrusions 31 are arranged on both sides of the flexible positioning plate 30, and the position of the flexible positioning plate 30 relative to the arc-shaped protrusion 31 is constructed to allow the deformation section 32 to undergo flexible deformation.

[0062] During use, when there is an abnormal line loss on the cable and the operating current passing through the abnormal line loss part of the cable becomes smaller, the magnetic field here is also reduced accordingly. Therefore, the reset spring 251 drives the limit slider 25 and the electrode sheet 2 22 to contact one of the electrode sheets 1 21 close to the cable direction to light up the warning light 23, and at the same time, it also synchronously drives the connected driven slide bar 250 to slide in the direction close to the cable. The movement of the driven slide bar 250 drives the connected arc-shaped protrusion 31 to move, and drives the deformation section 32 on the flexible positioning plate 30 to deform toward the side close to the cable; similarly, when the operating current passing through the abnormal line loss part of the cable increases, the reset spring 251 drives the driven slide bar 250 and the arc-shaped protrusion 31 to slide in the direction away from the cable, and the movement of the arc-shaped protrusion 31 drives the deformation section 32 on the flexible positioning plate 30 to slide in the direction away from the cable.

[0063] Based on this, the collector can accurately judge the position of the line loss on the cable through the warning of the warning light 23 and by observing the position of the deformation section 32 on the flexible positioning plate 30. Correspondingly, by observing the direction of the deformation position of the deformation section 32 on the flexible positioning plate 30, it can also assist the staff in judging whether the current passing through here is too small or too large.

[0064] Further, refer to Figure 8 and Fig. 9 As shown, a driven block 33 and a guide block 34 for limiting the position of the reset spring 251 are also provided on the connecting slide rod 131. At least two guide blocks 34 are provided. The inclined surfaces of the two guide blocks 34 are symmetrically arranged and arranged on both sides of the driven block 33. The driven block 33 is a flexible material with a certain elastic deformation ability to improve the stability after the reset spring 251 is driven to move, thereby facilitating the subsequent acquisition personnel to observe the position of the deformation section 32 on the flexible positioning plate 30.

[0065] When in use, by driving the driven slide rod 250 to slide, the driven slide rod 250 moves and drives the connected driven block 33 to slide synchronously. After the driven block 33 moves to contact and fit with the guide block 34, it continues to slide along the inclined surface of the guide block 34 and shrinks in the direction close to the connected driven slide rod 250. After crossing the corresponding guide block 34, the guide block 34 limits the reset movement of the driven block 33 and the driven slide rod 250.

[0066] When resetting is required, the collector drives the driven slide bar 250 to slide inside the connecting slide bar 131, so that the driven block 33 is relocated in the middle of the two guide blocks 34, thereby completing the resetting effect of the driven block 33, the driven slide bar 250, the arc-shaped protrusion 31 and the deformation section 32 on the flexible positioning plate 30.

[0067] During operation: the first step is to install the mounting ring 10 and the limiting ring 11 accordingly so that they are sleeved on the cable, and then the cable is adaptively clamped and limited by the clamping member 13.

[0068] Step 2: After completing the clamping and limiting of the cable, drive the device to slide on the cable, and collect and detect the position of the abnormal line loss on the cable through the clamping member 13. After the abnormality is detected, the output signal indicates the alarm terminal 2, and the alarm at the alarm terminal 2 reminds the collector that the cable line loss here is abnormal.

[0069] Step 3: After completing the collection, the collector uses the indication of the indicator 3 to accurately identify the location of the abnormal line loss on the cable.
