Abstract
Description
Technical Field
[0001] This invention belongs to the field of power grid line detection technology, specifically relating to a portable branch line positioning and insulation device. Background Technology
[0002] In power distribution networks, branch lines are numerous and widely distributed. Their insulation condition directly affects power supply reliability and operational safety. Furthermore, locating insulation faults in branch lines is a crucial step in ensuring power supply reliability. However, branch lines are exposed to complex outdoor environments for extended periods, making them susceptible to lightning strikes, humidity, and mechanical damage, leading to insulation aging and breakage. Failure to locate and address faults promptly can result in short circuits, power outages, or even electric shocks. This is particularly problematic in urban villages and old streets where branch lines are often concealed, with various cables such as internet and telephone lines intertwined, making comprehensive inspections challenging. The current method is challenging and poses significant risks to line loss management and user safety. The existing approach involves using safety tools such as ladders and clamp meters to climb the line and measure branch currents segment by segment to locate the fault. This method requires multiple climbs along the line, resulting in low efficiency and a large workload. Furthermore, ladders erected at road, street, or alley entrances can disrupt traffic and pose significant safety risks. Therefore, developing a portable, safe, and efficient branch line locating and insulation device is essential to address these issues. Summary of the Invention

The improved bridge balance detection circuit and the leakage current detection circuit are connected in parallel and then connected to the signal input terminal of the main control chip. The data processing unit communicates bidirectionally with the main control chip, and the human-machine interaction unit is connected to the I / O port of the main control chip. The telescopic detection probe is formed by slidingly mounting multiple sections of insulating material support rods. It has a grip at the lower end, an angle adjustment gimbal at the upper end, and a signal shielded cable embedded inside. The detection probe is detachably mounted on top of the angle adjustment gimbal, and its detection angle can be adjusted by the angle adjustment gimbal. The detection probe is equipped with a touch detection probe and a probe attitude sensor inside, and the probe attitude sensor is connected to the signal acquisition terminal of the main control chip. The wireless communication module includes a Bluetooth communication unit and a 4G / 5G communication unit, which are used to upload the detection data to the cloud while realizing data interaction between the portable host module and external terminal devices. The power supply module is a rechargeable lithium battery pack, which is connected to the power input terminal of the portable host module.
[0005] Furthermore, the portable host module is also equipped with a data storage unit, which can be used to store and back up the detection data.
[0006] Furthermore, the leakage current detection circuit is externally connected to an amplifier chip and a filter unit, wherein the input end of the amplifier chip is connected to the detection probe, and the output end is connected to the data processing unit through the filter unit.
[0007] Furthermore, the human-machine interaction unit consists of a display screen, control buttons, and an audible and visual alarm component, wherein the audible and visual alarm component can automatically trigger an alarm when an insulation fault is detected.
[0008] Furthermore, the data processing unit has a built-in fault location algorithm, which can output the precise location of the fault point by multi-dimensional data fusion calculation based on the detected leakage current value, bridge balance deviation value and probe position information.
[0009] The beneficial effects of the present invention are as follows: By setting up a telescopic detection probe and an angle adjustment gimbal, the present invention utilizes the telescopicity of the telescopic detection probe and the angle adjustment gimbal to adjust the detection angle of the detection probe, which can increase the convenience and applicability of line detection operation. Furthermore, with this structure, no additional climbing equipment is required during operation, which improves the efficiency of detection work and reduces the risk of operation.

Furthermore, by utilizing the fault location algorithm built into the data processing unit, it can accurately locate the fault point while detecting the insulation status of the line, thus solving the problems of low detection accuracy and inability to locate fault points in traditional equipment. By using a signal shielded cable, external electromagnetic interference can be avoided; by using a wireless communication module and a human-machine interface unit, maintenance personnel can easily view, manage, analyze, and execute commands. Overall, this invention has the advantages of being portable, safe, and efficient to use. Attached Figure Description

The portable main unit module has a built-in main control chip, an improved bridge balance detection circuit, a leakage current detection circuit, a data processing unit, and a human-machine interaction unit. The improved bridge balance detection circuit and the leakage current detection circuit are connected in parallel and then connected to the signal input terminal of the main control chip. The data processing unit communicates bidirectionally with the main control chip, and the human-machine interaction unit is connected to the I / O port of the main control chip. The telescopic detection probe is formed by slidingly fitting multiple sections of insulating material support rods, with a grip at its lower end. The portable host module is equipped with an angle-adjustable gimbal at the top and has a signal shielded cable embedded inside. The detection probe is detachably mounted on top of the angle-adjustable gimbal, and its detection angle can be adjusted by the angle-adjustable gimbal. The detection probe contains a touch-sensitive detection probe and a probe attitude sensor, and the probe attitude sensor is connected to the signal acquisition terminal of the main control chip. The wireless communication module includes a Bluetooth communication unit and a 4G / 5G communication unit, which are used to upload detection data to the cloud and realize data interaction between the portable host module and external terminal devices.

[0013] The portable host module also includes a data storage unit for storing and backing up detection data. The leakage current detection circuit is externally connected to an amplification chip and a filtering unit. The input of the amplification chip is connected to the detection probe, and its output is connected to the data processing unit via the filtering unit. The human-machine interface unit consists of a display screen, control buttons, and an audible and visual alarm component, which automatically triggers an alarm when an insulation fault is detected.

This structure increases the convenience and applicability of line testing operations, eliminating the need for additional climbing equipment, thus improving efficiency and reducing operational risks. Next, the device is switched from standby mode to testing mode, and the branch line is tested using the contact detection probe within the detection probe. During this process, the improved bridge balance detection circuit and leakage current detection circuit within the portable host module work together to increase detection accuracy through a dual detection mechanism. Finally, the data processing unit's built-in... The fault location algorithm, based on the detected leakage current value, bridge balance deviation value, and probe position information, uses multi-dimensional data fusion calculation to output the precise location of the fault point, thereby solving the problems of low detection accuracy and inability to locate fault points in traditional equipment.
