Description

Technical Field

[0001] The present invention relates to the technical field of circuit monitoring, and in particular to a system and method for analyzing and detecting a failure rate of a power transmission and distribution line. Background Art

[0002] Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. According to the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. The yield rate of the transmission line is the standard for judging whether the transmission line can be used. At present, the line display device is generally the result of manual detection. Currently, most of the detection is manual detection. This method uses too many people and takes up more economy. Moreover, manual detection is difficult to achieve comprehensive detection and has low accuracy. Summary of the invention

[0003] The embodiment of the present invention provides a power transmission and distribution line fault rate analysis and detection system and method, which ensures the transmission of the device by connecting the line card to the inside of the device, and the device can perform real-time detection after manual judgment, thereby ensuring the detection efficiency of the device, ensuring people's subsequent processing, and facilitating manual judgment.

[0004] To achieve the above object, the present invention provides a power transmission and distribution line fault rate analysis and detection system, comprising:

[0005] A data collection module, the data collection module comprising a support assembly and a limit rotating wheel;

[0006] A voltage difference calculation module, the voltage difference calculation module comprising a processor, a switch and a display are arranged on the front of the processor;

[0007] A signal transmission module, the signal transmission module comprising a rotating connector and a linear connection assembly, the rotating connector is located at the top of the switch, the rotating connector is communicated with the linear connection assembly, a support assembly is provided on the top of the linear connection assembly, and a limit rotating wheel is provided inside the support assembly;

[0008] A line detection module, the line detection module includes a housing assembly and a transition assembly, the housing assembly includes a mobile housing, a rotating wheel and a limit clamping plate, the limit clamping plates are two in number and are located on opposite sides of the mobile housing, the rotating wheel is located on both sides of the limit clamping plate and is rotatably connected to the mobile housing;

[0009] The transition assembly includes no less than three support rods, a sliding plate is arranged on the top of the support rod, a transmission wheel penetrating the sliding plate is arranged on the front of the sliding plate, a detection assembly is arranged on the outside of the transition assembly, the detection assembly includes a sliding block, the sliding block is threadedly connected to the output shaft of the transmission wheel, a fixing rod is arranged on the top of the sliding block, and a detection head is arranged between the two fixing rods;

[0010] Furthermore, the number of the rotating connectors is no less than two, the processor, rotating connector, linear connection assembly, support assembly and limit wheel are all linearly connected, and the limit wheel is directly connected to the line to be measured, so that the voltage can be transmitted to the interior of the processor for subsequent measurement and observation.

[0011] Furthermore, the linear connection assembly includes a line body, and the top of the line body is rotatably connected to a rotating rod to ensure the rotation of the device and facilitate subsequent processing.

[0012] Furthermore, the support assembly includes a support seat, a rotating support plate is arranged on the top of the support seat, a stabilizing cover plate is arranged on the top of the rotating support plate, the rotating support plate and the stabilizing cover plate are connected by a latch, so as to ensure that the limiting wheel rotates inside the support assembly, thereby ensuring the transmission of the device, and the support seat is fixedly connected to the rotating rod.

[0013] Furthermore, the signal of the processor is transmitted and transmitted to the inside of the processor for processing. When the line contacts the limit wheel, voltage fluctuations will occur. When the voltage fluctuation reaches a certain level, it will be displayed on the display and stored in the processor, which is convenient for manual judgment. When the voltage is too large, it can be manually turned off by pressing the switch. During this period, the device will record in real time to facilitate subsequent processing.

[0014] Furthermore, the processor's records can be set with certain standards as a reference for whether there is a fault. The reference can be set according to the voltage size and can be divided into too high voltage, too low voltage or no voltage. When too high voltage, too low voltage or no voltage is detected, the information is stored and recorded to facilitate subsequent judgment.

[0015] Furthermore, the line detection is performed outside the rotating wheel, the limit clamp limits the running track of the line, and then the line is observed and analyzed by the detection head to determine whether the line is damaged, and then the information is stored.

[0016] Furthermore, the manual decision is a standard of manual judgment, which is a summary judgment of various records. According to the collected data, the line is analyzed, and according to the measured line, the recorded line is calculated and processed. The processing result is used as the standard for whether the line can be reused, and is divided into usable, risky and unusable. Usable means that the line runs well and there is no damage between the lines. Risky means that there are certain data fluctuations in part of the line. Manual judgment is made whether it affects the use, and then it is converted into usable or unusable. Unusable means that data fluctuations occur in multiple locations of the line or there is serious damage at a certain location of the line that cannot be repaired; then the situation is summarized.

[0017] A method for online positioning and monitoring of transmission line faults comprises the following steps:

[0018] S1, in preparation for subsequent inspection, the line is laid, inserted between the support assembly and the limit wheel and inside the shell assembly, and then the line is observed and laid flat to prevent the subsequent line from running smoothly. In this process, whether there is obvious damage to the line is detected;

[0019] S2, run the line, analyze the line conditions, record the voltage in real time, make judgments based on the fluctuation signals generated by the records, store the obvious fluctuations, and judge and record the length of the non-obvious fluctuations;

[0020] S3, information processing, judging whether the faulty part meets the requirements, if not, the line is recorded and reported, if it meets the requirements, the part is stored and recorded, and the line is repaired at the same time;

[0021] S4, manual repair, repair the treated line, measure the section again after the repair, and judge the possibility of subsequent damage. If the damage risk is high, perform S3 again, and then judge whether the line meets the requirements;

[0022] S5, fault summary, processes the overall information according to the results obtained by the fault analysis module, and reports the percentage by dividing the destroyed number by the total number and multiplying it by 100%, and sends it to the management terminal.

[0023] The beneficial effects of the above technical solution provided by the embodiment of the present invention include at least:

[0024] (1) The present invention observes the line by setting up a data acquisition module and a signal transmission module, transmits the information to the display module and the data storage module for processing according to the transmitted information, quickly records and judges the fault location according to the change of the waveform, and records the device in combination with the overall length of the line.
