Technical Field

[0001] The invention belongs to the technical field of cable defect detection, and in particular relates to a cable defect positioning detection device based on a frequency domain reflection method. Background Art

[0002] In the power system, cables are important facilities for transmitting electric energy, and their safety is crucial to the stable operation of the power system. Cables may have defects during long-term operation due to various factors (such as insulation aging, environmental factors, mechanical damage, etc.). If these defects are not discovered and handled in time, they may cause cable damage or even cause safety accidents such as fire and explosion. Therefore, regular inspection and maintenance of cables is an important measure to ensure the safe operation of the power system.

[0003] At present, the detection methods of cable defects mainly include high frequency method, time domain reflectometry (TDR) and frequency domain reflectometry (FDR). Among them, frequency domain reflectometry (FDR) is widely used in the location detection of cable defects due to its sensitivity to changes in cable length. Traditional frequency domain reflectometry detection devices usually use complex electronic circuits and sophisticated signal processing technology, which makes the equipment cost high and has high requirements on operators. In addition, traditional devices may have problems such as inconvenient operation and low detection efficiency during use.

[0004] Therefore, in order to improve the efficiency and accuracy of cable defect location detection, reduce equipment costs, and simplify the operation process, the present invention provides a cable defect location detection device based on frequency domain reflection method, which has the advantages of simple structure, easy operation, and low cost. Summary of the invention

[0005] The purpose of the present invention is to provide a cable defect location detection device based on frequency domain reflection method, aiming to solve the problem of xx in the prior art.

[0013] As a preferred solution of the present invention, a ratchet is fixedly connected to the circumferential surface of the cylinder, and the side end of the second rectangular plate is rotatably connected to a ratchet via a rotating shaft. The ratchet is meshed with the ratchet, and a torque spring is connected between the ratchet and the ratchet.

[0014] As a preferred solution of the present invention, a second handle is fixedly connected to the side end of the take-up reel.

[0015] As a preferred solution of the present invention, the upper end of the main body is threadedly connected to a cover plate via bolts, and the upper end of the cover plate is fixedly connected to a first handle.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this solution, the device uses the principle of frequency domain reflection method. By transmitting a signal of a specific frequency to the cable and analyzing its reflected waveform, it can accurately locate the defects inside the cable, such as breakpoints, short circuits, or insulation damage. The design of the slide and slider allows the cable to move smoothly on the device. Combined with the take-up reel and ratchet structure, it can ensure the stability and tension control of the signal transmission line during the detection process, thereby improving the detection accuracy and efficiency. The addition of the torque spring further ensures stable operation under different tension requirements, making the operation more flexible and adaptable to a variety of cable conditions.

The setting of the second handle and the first handle makes it easier to carry and operate the equipment, and it can be easily completed whether it is adjusting the position or performing manual cable reeling and unreeling operations. The integration of the display screen and the display light directly provides intuitive feedback on the test results, and users can quickly understand the health status of the cable on site without an external display. In addition, the specially designed socket facilitates the connection of external test instruments or data recording devices, enhancing the functional expandability of the device. The use of the cover not only protects the internal components, but also maintains the overall appearance and dustproof and waterproof performance of the equipment. The stable connection of the base ensures the stability of the equipment in various working environments, and it can be safely operated even on uneven ground. In summary, these designs have jointly improved the practicality and user-friendliness of the equipment, making cable detection work more efficient and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
