Description

Technical Field

[0001] This utility model belongs to the field of wire detection technology, specifically relating to a fault identification device for power distribution lines. Background Technology

[0002] Electrical wire fault identification is a crucial aspect of power systems and household electrical systems. Its purpose is to detect and analyze fault phenomena, quickly locate the fault point, and take appropriate measures to ensure the safe operation of the power system and the safety of household electricity use.

[0003] However, in implementing the relevant technologies, the following problems were found with the above technical solutions: when a fault occurs in the power distribution line, it can usually only detect which power distribution line is faulty, but cannot accurately detect the location of the fault in the power distribution line. Therefore, in most cases, the entire power distribution line can only be replaced, which wastes a lot of power distribution lines.

[0004] Therefore, a fault identification device for power distribution lines is proposed to solve the above problems. Utility Model Content

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0017] Implementation

[0018] Please see Figure 1 -4, a fault identification device for power distribution lines, comprising: an insulating outer shell 1 and an inner liner 2; A Hall current sensor 3 is fixedly installed inside the inner tank 2. An ink cartridge 4 is fixedly installed inside the insulating shell 1 and the inner tank 2. A pump 5 is fixedly installed on the top of the insulating shell 1. An ink supply tube 6 is fixedly installed at the input end of the pump 5. An ink outlet tube 7 is fixedly installed at the output end of the pump 5. A nozzle 8 is fixedly installed at one end of the ink outlet tube 7. A PCL processor 9 is fixedly mounted on the top of the insulating housing 1, and a control panel 10 is fixedly mounted on the side of the insulating housing 1.

[0019] The technical solution provided in this embodiment is as follows: In use, firstly, the undetected wire 17 is passed through the limiting member 11 and the inner liner 2. Then, the undetected wire 17 is placed between the pulley 14 and the drive wheel 16. Then, the electric push rod 12 is activated to make the pulley 14 and the drive wheel 16 fit tightly against the undetected wire 17. Then, the motor 15 is activated to rotate the drive wheel 16, causing the undetected wire 17 to move. Then, the wire is detected by the Hall current sensor 3. Then, the detected data is sent to the PC1 processor. When a fault is detected in the wire, the pump 5 is activated to draw ink from the inside of the ink cartridge 4 through the ink supply pipe 6. Then, the ink is sprayed onto the wire through the ink outlet pipe 7 and the nozzle 8, thereby marking the damaged location of the wire, which is convenient for workers to repair later.

[0020] Furthermore, a limiting component 11 is fixedly installed inside the inner liner 2, an electric push rod 12 is fixedly installed inside the inner liner 2, a bracket 13 is fixedly installed at the bottom end of the electric push rod 12, and a pulley 14 is rotatably installed inside the bracket 13.

[0021] Specifically, by fixing the electric actuator 12 inside the inner liner 2, the undetected wire 17 can be restrained by the pulley 14 and drive wheel 16 when the electric actuator 12 is activated, preventing the wire from bending and affecting the detection effect.

[0022] Furthermore, a motor 15 is fixedly installed inside the inner liner 2, and a drive wheel 16 is fixedly installed at one end of the motor 15. An undetected wire 17 is movably arranged between the drive wheel 16 and the pulley 14.

[0023] Specifically, by fixing the drive wheel 16 to one end of the motor 15, the drive wheel 16 can be rotated when the motor 15 is started, thereby moving the undetected wire 17 through the drive wheel 16 and the pulley 14, and thus detecting the undetected wire 17.

[0024] Furthermore, a support foot 18 is fixedly installed at the bottom of the insulating shell 1, and an insulating pad 19 is fixedly installed at the bottom end of the support foot 18.

[0025] Specifically, by fixing the insulating pad 19 to the bottom of the support foot 18, the current can be prevented from contacting the ground through the support foot 18, thus preventing it from affecting the accuracy of the test.

[0026] Furthermore, there are two nozzles 8, and the two nozzles 8 are located on both sides of the Hall current sensor 3.

[0027] Specifically, by placing two nozzles 8 on either side of the Hall current sensor 3, ink can be ejected from the two nozzles 8 to mark the location of the damaged wire when the Hall current sensor 3 senses a current fluctuation.

[0028] Furthermore, the PCL processor 9, Hall current sensor 3, motor 15, and control panel 10 are connected together by wires.

[0029] Specifically, by connecting the PCL processor 9, Hall current sensor 3, motor 15 and control panel 10 together with wires, the PCL processor 9 can receive and process the current fluctuations sensed by the Hall current sensor 3, and display the processed data through the control panel 10, so that workers can have a clearer understanding of the wire damage.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
