[0028] like Figures 1 to 3 As shown, a high-voltage signal test transmission device for a distribution line described in an embodiment of the present invention comprises a test transmission controller 1; a winding box 11 is fixedly connected to the outer wall of the test transmission controller 1; the interior of the winding box 11 is rotatably connected to two winding rollers 12 through two torsion springs; cables 13 are fixedly connected to the outer walls of the two winding rollers 12; one end of the cable 13 away from the winding roller 12 is fixedly connected to a connector 14; when testing faults in multiple distribution lines, it is necessary to connect the grounding wire and the signal output wire separately for use. First, the test transmission controller 1 is stably placed on the fault point of the distribution line. Two cables 13 are wound inside the winding box 11. Two cables 13 with different functions are respectively wound around the two winding rollers 12 through torsion springs. The two cables 13 are respectively a grounding wire and a signal output wire. The two connectors 14 are connected to the clips respectively, and the two cables 13 are pulled simultaneously Pull it out, the grounding wire is connected to the actual earth, and the high-voltage signal output line is connected to the line to be tested. After the test controller 1 is connected to an external portable mobile power supply, the test begins. Turn on the switch of the distribution line high-voltage signal test device, and observe whether the voltage knob is at zero. The green light at zero is on, and observe the grounding status prompted on the test controller 1. Then slowly rotate the voltage knob to adjust. When the voltage is increased to the time setting value, the test controller 1 will prompt that there is grounding, and the fault light will flash and the test instrument will be disconnected, indicating that the line has a fault grounding. Return the voltage knob to zero and turn off the power, remove the two clips, and the torsion spring elastic force resets to drive the winding roller 12 to rotate. The two winding rollers 12 synchronously reel in the two cables 13, and reel the two cables 13 in the reeling box 11. Pick up the test controller 1 and you can carry it to the next fault point to continue the test, thereby improving the efficiency of the distribution line high-voltage signal test.

As the cable 13 is wound inside the winding box 11 after use, the coil of the cable 13 becomes larger and larger, which can push out the connecting rod 21 connected to one end of the extrusion plate 2. At the same time, when the connecting rod 21 slides into the winding box 11, the remaining length of the round rod of the winding roller 12 exposed outside the winding box 11 can be observed, so as to judge the length of the remaining cable 13 in the winding box 11 and reduce the possibility of the cable 13 being pulled and damaged.

[0030] A pressure sensor 3 is fixedly connected to the outer wall of the winding box 11 near the connecting rod 21, and the pressure sensor 3 is electrically connected to the trial delivery controller 1; the elastic force of the No. 1 elastic member 22 pulls the wide plate of the connecting rod 21 to squeeze and trigger the pressure sensor 3; when the cable 13 is pulled and used, as the end of the cable 13 connected to the connecting head 14 is continuously pulled away, the No. 1 elastic member 22 pulls the round rod of the connecting rod 21 to slide into the interior of the winding box 11 until the wide plate of the connecting rod 21 squeezes the pressure sensor 3, and the pressure sensor 3 sends a signal to the trial delivery controller 1, and the trial delivery controller 1 issues an alarm that the cable 13 is about to be pulled out completely, and the position of the trial delivery controller 1 needs to be adjusted, which serves to warn that the cable 13 is too short and needs to be adjusted.

When the battery pack is out of power, the sealing plate 41 is removed to replace the battery pack, thereby making the high-voltage signal trial transmission device of the distribution line portable and electrically connected.

[0032] The end of the power box 4 is fixedly connected to a No. 1 fixing frame 5; the inner wall of the No. 1 fixing frame 5 is installed with a limit plate 51 through a No. 2 elastic member; the end of the power box 4 is provided with an extrusion component, which is used to squeeze the limit plate 51 to slide down and engage with the blocking plate 41 to limit the position; when the battery pack is fixed inside the power box 4, the limit plate 51 will be elastically driven by the No. 2 elastic member to slide up on the inner wall of the No. 1 fixing frame 5 in the initial state, and the battery pack is directly inserted into the interior of the power box 4, and then the blocking plate 41 is inserted into the interior of the power box 4 to fit the battery pack, and the limit plate 51 is pressed down by the extrusion component to slide, and the limit plate 51 slides down and is clamped on the outer wall of the blocking plate 41, and the No. 2 elastic member contracts and is stressed, so that the battery pack is clamped inside the power box 4 for use, thereby playing the role of fixing the battery pack.

[0033] The extrusion assembly includes a No. 2 fixing frame 6, a roller 61, a connecting plate 62 and a bolt 63; the No. 2 fixing frame 6 is fixedly connected to the end of the power box 4, and the No. 2 fixing frame 6 is arranged opposite to the No. 1 fixing frame 5; the roller 61 is rotatably connected to the inner wall of the No. 2 fixing frame 6; the connecting plate 62 is fixed to the outer wall of the roller 61; the bolt 63 is threadedly connected to the No. 1 fixing frame 5, and the bolt 63 simultaneously penetrates the No. 1 fixing frame 5 and the connecting plate 62; when the battery pack is connected for portable use, the No. 2 fixing frame 6 is fixed to the end of the power box 4 to support the roller 61, and the connecting plate 62 is pressed on the No. 1 fixing frame 5 as the roller 61 rotates, and the limiting plate 51 squeezes the No. 2 elastic member to shrink and slide down. At this time, the limiting plate 51 clamps and fixes the sealing plate 41 in the power box 4, and uses the bolt 63 to simultaneously penetrate the No. 1 fixing frame 5 and the connecting plate 62 to fix it, thereby playing a role in fixing and limiting the battery pack.

[0034] like Figures 1 to 5 As shown, the end of the winding box 11 is fixedly connected to a connecting frame 7; guide plates 71 are fixedly connected to one side of both ends of the outer wall of the connecting frame 7, and a circular ring is fixedly connected to one end of the guide plate 71; when multiple cables 13 are wound up in the winding box 11 and moved to the next fault point for trial delivery, the connecting frame 7 is fixed to the end of the winding box 11, multiple shoulder straps are taken out and fixed on the connecting frame 7, and the other end of the shoulder strap is fixed on the connecting plate 62, so that the high-voltage signal test delivery device for the distribution line can be carried easily, and during the trial delivery, the cable 13 is pulled out of the winding box 11 and passed through the circular ring of the guide plate 71, and the cable 13 is guided by the circular ring to reduce the wear of the cable 13 dragged on the ground.

[0035] like Figure 1 , Figures 3 to 5As shown, the inner wall of the connecting plate 62 is slidably connected with a hole plate 8, and the outer wall of the hole plate 8 is provided with a plurality of through holes corresponding to the bolts 63; the end of the hole plate 8 away from the connecting plate 62 is fixedly connected with a guide ring 81; when the signal output line is connected to the fault line, if the pulled out cable 13 is too long, the cable 13 is not only easy to fall off the fault line due to its own gravity, but also easy to be seriously worn out by dragging on the ground for a long time, and after the limit of the bolt 63 is released by the connecting plate 62, the connecting plate 62 rotates with the roller 61, and when the test controller 1 is placed flat, the blocking plate 41 can fix the battery pack inside the power box 4, and the connecting plate 62 is rotated from the horizontal state to the vertical state, and the hole plate 8 is pulled out and slid on the inner wall of the connecting plate 62, and the bolt 63 is used to pass through the connecting plate 62 and the hole plate 8 to fix it, and the pulled out cable 13 passes through the guide ring 81 to connect to the fault line, and the guide ring 81 can increase the distance of the cable 13 from the ground, and reduce the situation of the cable 13 falling off and dragging wear caused by pulling too long.

[0036] like Figure 1 and Figure 3 As shown, the outer wall of the test sending controller 1 is fixedly connected with two fixing plates 9; the inner walls of the two fixing plates 9 are rotatably connected with a rotating shaft 91; the outer side of the rotating shaft 91 is fixedly connected with an upper cover plate 92; when the test sending controller 1 is portable, the two fixing plates 9 are fixed to the outer wall of the test sending controller 1, and an upper cover plate 92 is hingedly connected by two rotating shafts 91. When the test sending fault point is transferred, the upper cover plate 92 can be flipped over to cover the test sending controller 1, so as to shield the surface of the test sending controller 1, reduce the damage of various control knobs touching the test sending controller 1 during the transfer process, and play a role in protecting the control parts of the test sending controller 1.

[0037] The four corners of the bottom end of the test transmission controller 1 are all threadedly connected with threaded rods 93; the bottom ends of the four threaded rods 93 are fixedly connected to bases 94; when the distribution line high-voltage signal test transmission device is used for test transmission and detection on rough ground, the four threaded rods 93 are threadedly fixed to the four corners of the bottom end of the test transmission controller 1, and the four bases 94 are respectively fixed to the bottom ends of the four threaded rods 93 and supported on the ground. The connection height of the four threaded rods 93 can be freely adjusted according to the flatness of the ground, so as to improve the stability of the distribution line high-voltage signal test transmission device during use. At the same time, when moving between short-distance fault points, the pulled cable 13 can be temporarily wrapped around the four threaded rods 93, which is convenient for short-distance portable transfer.

[0038] Working process: When testing multiple distribution line faults, it is necessary to connect the ground wire and the signal output wire separately. First, place the test controller 1 stably on the distribution line fault point. Two cables 13 are wound inside the winding box 11. The two cables 13 with different functions are wound on the two winding rollers 12 through torsion springs. The two cables 13 are the ground wire and the signal output wire respectively. Connect the two connectors 14 to the clips respectively, pull the two cables 13 out at the same time, connect the ground wire to the actual earth, and connect the high-voltage signal output wire to the line to be tested. After the test controller 1 is connected to a portable mobile power supply, start the test and turn on the distribution. Turn on the switch of the high-voltage signal test transmission device for the power line, observe whether the voltage knob is at the zero position, the green light at the zero position is on, observe the grounding status prompted on the test transmission controller 1, and then slowly rotate the voltage knob to adjust. When the voltage is increased to the time setting value, the test transmission controller 1 will prompt that there is a grounding, the fault light will flash and the test transmission instrument will be disconnected, indicating that the line has a grounding fault. Return the voltage knob to zero and turn off the power, remove the two clips, and the torsion spring elastic force will reset to drive the winding roller 12 to rotate. The two winding rollers 12 will synchronously reel in the two cables 13, and the two cables 13 will be reeled in the reeling box 11. Pick up the test transmission controller 1 and you can carry it to the next fault point to continue the test transmission, which will improve The efficiency of the high-voltage signal test of the distribution line is improved; when the cable 13 is pulled out of the reel box 11 for use, the No. 1 elastic member 22 elastically pulls the wide plate of the connecting rod 21, causing the round rod to slide into the reel box 11, and the extrusion plate 2 is pressed against the outer wall of the cable 13 remaining in the reel box 11, which helps prevent the cable 13 from being pulled and reeled by the reel roller 12 connected to the torsion spring. As the cable 13 is reeled in the reel box 11 after use, the cable 13 becomes larger and larger, which can push out the connecting rod 21 connected to one end of the extrusion plate 2. At the same time, during the process of the connecting rod 21 sliding into the reel box 11, the bare round rod of the reel roller 12 can be observed. The remaining length exposed outside the winding box 11 is used to judge the length of the remaining cable 13 in the winding box 11, thereby reducing the possibility of the cable 13 being damaged by pulling. When the cable 13 is pulled and used, as the end of the cable 13 connected to the connector 14 is continuously pulled away, the first elastic member 22 pulls the round rod of the connecting rod 21 to slide into the winding box 11 until the wide plate of the connecting rod 21 squeezes the pressure sensor 3, and the pressure sensor 3 sends a signal to the trial delivery controller 1, and the trial delivery controller 1 issues an alarm that the cable 13 is about to be completely pulled out, and the position of the trial delivery controller 1 needs to be adjusted, which serves as a warning that the cable 13 is too short and needs to be adjusted.

[0039] When connecting the test transmission controller 1 to a power source, it is usually cumbersome to use an external portable mobile power source, and the portable mobile power source is not easy to carry. The power box 4 is fixed on one side of the test transmission controller 1, the battery pack is inserted into the inside of the power box 4, and the battery pack is fixed inside the power box 4 using a blocking plate 41 for power supply. When the battery pack is out of power, the blocking plate 41 is removed to replace the battery pack, thereby making the distribution line high-voltage signal test transmission device portable for power connection. When the battery pack is fixed inside the power box 4, the limit plate 51 will be elastically driven by the second elastic member in its initial state to slide up on the inner wall of the first fixing frame 5, and the battery pack is directly inserted into the inside of the power box 4, and then the blocking plate 41 is inserted into the power box 4 immediately afterwards. The battery pack fits inside the box 4, and the limiting plate 51 is pressed down by the extrusion assembly to slide. The limiting plate 51 slides down and is clamped on the outer wall of the blocking plate 41. The No. 2 elastic member contracts and is stressed, so that the battery pack is clamped inside the power box 4 for use, which plays a role in fixing the battery pack; when the battery pack is clamped for portable use, the No. 2 fixing frame 6 is fixed to the end support roller 61 of the power box 4, and the connecting plate 62 is pressed on the No. 1 fixing frame 5 as the roller 61 rotates. The limiting plate 51 squeezes the No. 2 elastic member and contracts and slides down. At this time, the limiting plate 51 clamps and fixes the blocking plate 41 in the power box 4, and bolts 63 are used to penetrate the No. 1 fixing frame 5 and the connecting plate 62 at the same time to fix the battery pack;

[0040] When multiple cables 13 are rolled up in the reel box 11 and moved to the next fault point for trial delivery, the connecting frame 7 is fixed to the end of the reel box 11, multiple shoulder straps are taken out and fixed on the connecting frame 7, and the other end of the shoulder straps is fixed on the connecting plate 62, so as to facilitate the portable carrying of the distribution line high-voltage signal trial delivery device, and during the trial delivery, the cable 13 is pulled out of the reel box 11 and passed through the ring of the guide plate 71, and the cable 13 is guided by the ring to reduce the wear of the cable 13 dragged on the ground; when the signal output line is connected to the fault line, if the pulled out cable 13 is too long, the cable 13 is not only easy to fall off due to its own gravity Faulty lines, and are prone to serious wear and tear due to long-term mopping. After the limit of the bolt 63 is released by the connecting plate 62, the connecting plate 62 rotates with the roller 61. When the test controller 1 is placed flat, the blocking plate 41 can fix the battery pack inside the power box 4. The connecting plate 62 is rotated from a horizontal state to a vertical state, and the orifice plate 8 is pulled out and slid on the inner wall of the connecting plate 62. The bolt 63 is used to pass through the connecting plate 62 and the orifice plate 8 to fix it. The pulled out cable 13 passes through the guide ring 81 to connect to the faulty line. The guide ring 81 can increase the distance between the cable 13 and the ground, reducing the situation where the cable 13 that is pulled too long falls off and is dragged and worn;

[0041] When the test sending controller 1 is portable, two fixing plates 9 are fixed to the outer wall of the test sending controller 1, and an upper cover plate 92 is hingedly connected through two rotating shafts 91. When the test sending fault point is transferred, the upper cover plate 92 can be flipped over to cover the test sending controller 1, shielding the surface of the test sending controller 1, reducing the damage of various control knobs touching the test sending controller 1 during the transfer process, and playing a role in protecting the control parts of the test sending controller 1;

[0042] When the high-voltage signal test transmission device for distribution lines is used for test transmission and detection on rough ground, four threaded rods 93 are threadedly fixed on the four corners of the bottom end of the test transmission controller 1, and four bases 94 are respectively fixed on the bottom ends of the four threaded rods 93 to support the ground. The connection height of the four threaded rods 93 can be freely adjusted according to the flatness of the ground, so as to improve the stability of the high-voltage signal test transmission device for distribution lines during use. At the same time, when moving between short-distance fault points, the pulled out cable 13 can be temporarily wrapped around the four threaded rods 93, which is convenient for short-distance portable transfer.
