Description

Technical Field

[0001] This utility model relates to the field of power detection technology, and in particular to a cable fault detection device. Background Technology

[0002] With the rapid development of power systems, cables are increasingly widely used in power transmission and distribution systems. Due to the complex operating environment of cables, they are frequently affected by external mechanical damage, insulation aging, moisture breakdown, and other factors. Therefore, it is necessary to regularly use cable fault detection devices to inspect cables to ensure their normal use.

[0003] Currently, commonly used cable fault detection devices include a housing, a power supply module, a signal processing module, a wireless data transmission module, a human-machine interface module, and a cable detection probe assembly. The housing has a mounting cavity and ventilation holes and a probe connection hole on its surface. The ventilation holes are connected to the mounting cavity. The housing consists of an upper housing section and a lower housing section, with the rear sides of the upper and lower housing sections rotatably connected by a hinge. The human-machine interface module is located on the upper surface of the upper housing section. The signal processing module, wireless data transmission module, and human-machine interface module are housed in the mounting cavity. The wireless data transmission module, human-machine interface module, and probe connection hole are all connected to the signal processing module. The power supply module provides power to the signal processing module, wireless data transmission module, and human-machine interface module. The cable detection probe assembly is detachably connected to the probe connection hole. The signal processing module analyzes the signals detected by the cable detection probe assembly to determine if a cable fault exists. The wireless data transmission module connects to an external terminal to send the detection results for remote viewing and data archiving. Since both the wireless data transmission module and the signal processing module are located in the mounting cavity, and there is no partition between them, mutual interference occurs between them, affecting their performance and thus reducing the effectiveness of the cable fault detection device.

The housing 1 has an installation cavity, and the housing 1 has heat dissipation holes 11 and a detection probe connection hole 12. The heat dissipation holes 11 communicate with the installation cavity. The housing 1 includes an upper housing part 13 and a lower housing part 14. The rear side of the upper housing part 13 and the rear side of the lower housing part 14 are rotatably connected by a hinge. The human-machine interaction module is located on the upper surface of the upper housing part 13. The signal processing module 3, the wireless data transmission module 4, and the human-machine interaction module are all located in the installation cavity. The wireless data transmission module 4, the human-machine interaction module, and the detection probe connection hole 12 are all connected to the signal processing module 3. Module 2 provides power to the signal processing module 3, the wireless data transmission module 4, and the human-machine interaction module. The cable detection probe assembly 5 is detachably connected to the detection probe connection hole 12. Module 2 also includes a module mounting frame 6, which is horizontally matched and installed in the mounting cavity. The module mounting frame 6 is provided with a partition, which divides the module mounting frame 6 into a first mounting cavity 61 and a second mounting cavity 62. The first mounting cavity 61 and the second mounting cavity 62 are separated from each other. The signal processing module 3 is located in the first mounting cavity 61, and the power module 2 and the wireless data transmission module 4 are located in the second mounting cavity 62. A sealing structure 15 is provided between the upper housing part 13 and the lower housing part 14. An anti-slip structure 16 is provided on the lower surface of the lower housing part 14. The heat dissipation hole 11 has a regular hexagonal cross-section.

[0020] The signal processing module 3 and the wireless data transmission module 4 are separated by a partition, which reduces mutual interference between them, ensures the effectiveness of their use, and improves the effectiveness of the cable fault detection device. In addition, the module mounting frame 6 provides the installation positions for the signal processing module 3, the power supply module 2, and the wireless data transmission module 4, facilitating their installation.

[0021] To ensure the effectiveness of the signal processing module 3, a preferred structure of the signal processing module 3 of this utility model is as follows: The signal processing module 3 includes a signal amplification unit, a filtering unit, and a processing unit. The amplification unit amplifies the weak pulse or induced signal from the cable detection probe assembly 5 with low noise. The filtering unit adopts a multi-stage active / passive combined filtering to suppress power frequency and broadband electromagnetic interference. The processing unit samples and performs time-domain analysis on the amplified and filtered signal, calculates the distance between the fault point and the sampling end based on the pulse reflection characteristics, and outputs the waveform, feature points, and positioning results.

[0022] The wireless data transmission module 4 supports Wi-Fi / Bluetooth, sending the original waveform and analysis results to an external terminal for remote viewing and data archiving.

[0023] To ensure the strength of the enclosure 1, the material of the enclosure 1 is preferably aluminum alloy, and the upper enclosure part 13 and the lower enclosure part 14 are both integral structures.

[0024] The sealing structure 15 improves the sealing effect between the upper housing 13 and the lower housing 14, reducing the possibility of external water entering the housing 1 and enabling the cable fault detection device to maintain normal operation even in heavy rain or humid environments. To facilitate the installation and assembly of the sealing structure 15, for example... Figure 1 As shown, the sealing structure 15 is a sealing ring, which is fitted onto the outside of the upper housing part 13 and the lower housing part 14. The material of the sealing ring is preferably rubber.

[0025] The anti-slip structure 16 increases the friction with the contact surface, effectively preventing accidental slippage in outdoor or vibrating environments and improving the stability of the device. To further enhance the performance of the anti-slip structure 16, for example... Figure 1 As shown, the anti-slip structure 16 preferably includes four anti-slip pads, which are respectively disposed at the corners of the lower housing portion 14. The lower housing portion 14 is preferably rectangular in shape, and the four anti-slip pads are respectively disposed at the four right angles of the lower housing portion 14.

[0026] The heat dissipation hole 11 has a regular hexagonal cross-section. Compared to the rectangular heat dissipation holes in the prior art, the regular hexagonal heat dissipation hole 11 has better structural strength and airflow guidance efficiency, thus improving the heat dissipation effect of the entire device. To further improve the heat dissipation effect of the entire device, for example... Figure 3 , Figure 4 As shown, this utility model also includes a heat dissipation grille 7, which is disposed inside the heat dissipation hole 11. The heat dissipation grille 7 not only guides airflow and improves heat dissipation, but also blocks external impurities, reducing the possibility of impurities entering the housing 1.

[0027] The cable testing probe assembly 5 contacts the cable under test to obtain a signal and transmits the signal to the signal processing module 3. To improve the performance of the cable testing probe assembly 5, a preferred structure of this utility model is as follows: the cable testing probe assembly 5 includes a connecting shield wire and a cable testing probe, and the cable testing probe and the connecting shield wire are detachably connected. The cable testing probe realizes the injection and reflection signal acquisition of detection pulses through the connecting shield wire, which improves the anti-interference capability and applicability. The detachable connection between the cable testing probe and the connecting shield wire allows the cable testing probe to be replaced, and different cable testing probes can be selected according to the cable insulation type and site conditions.

[0028] To facilitate the use of cable fault detection devices, for example... Figure 1 , Figure 2 As shown, a preferred structure of the human-machine interaction module is as follows: The human-machine interaction module includes a display screen 81, a start function button 82, a stop function button 83, a menu function button 84, a green indicator light 85, a yellow indicator light 86, and a red indicator light 87. The display screen 81, start function button 82, stop function button 83, menu function button 84, green indicator light 85, yellow indicator light 86, and red indicator light 87 are all located on the upper surface of the upper housing 13. The display screen 81, start function button 82, stop function button 83, menu function button 84, green indicator light 85, yellow indicator light 86, and red indicator light 87 are all connected to the signal processing module 3. The display screen 81 is used for menu navigation, parameter setting, real-time waveform display, and fault distance display; the menu function button 84 is used for mode switching, threshold setting, and calibration initiation; the green indicator light 85, yellow indicator light 86, and red indicator light 87 are used for fault status indication. A constantly lit green indicator light 85 indicates that no cable fault has been detected; a constantly lit yellow indicator light 86 indicates that the cable fault is near the detection point; and a constantly lit red indicator light 87 indicates that the location of the cable fault has been detected.

[0029] The start button 82, stop button 83, and menu button 84 are preferably waterproof silicone buttons, and the display screen 81 is preferably a high-brightness visible LCD screen. To improve the usability of the display screen 81, the human-computer interaction module also includes an ultraviolet sensor 88, which is connected to the signal processing module 3. The ultraviolet sensor 88 intelligently detects the ambient ultraviolet intensity and transmits the detection data to the signal processing module 3. The signal processing module 3 automatically adjusts the screen brightness and color temperature based on the obtained data, reducing eye fatigue while ensuring display quality.

[0030] To further improve the performance of the display screen 81, for example... Figure 1 , Figure 2 and Figure 5 As shown, a rotating sleeve is provided on one side of the display screen 81, and a rotating shaft is provided on the upper surface of the upper housing 13. The display screen 81 is rotatably mounted on the rotating shaft via the rotating sleeve. The display screen 81 can rotate upward, allowing it to adapt to different operating needs such as squatting, sitting, and standing. The maximum opening angle of the display screen 81 is 70°. When the display screen 81 rotates upward, it can be fixed by the friction between the rotating sleeve and the rotating shaft, or it can be fixed by an external support structure.

[0031] To extend the battery life, power module 2 is a replaceable, rechargeable lithium battery pack, and an external power interface 17 is provided on the housing 1, which is connected to power module 2. Charging of power module 2 is achieved by connecting to an external power source through external power interface 17.

[0032] To facilitate the carrying of cable fault detection devices, for example... Figure 1 As shown, this utility model is also provided with a handle 9, and the housing 1 is provided with an installation notch. The handle 9 is rotatably mounted on the side wall of the installation notch.
