What Is the Most Effective Way of Power Inspection?

Jun 05, 2023

The best line inspection method is to use unmanned aircraft inspection, which can carry visible light, infrared thermal imaging and ultraviolet imaging and other equipment to carry out high-precision inspection of transmission lines, which not only overcomes the distance between the ground inspection team and the observation field angle The problem of being too small also solves the problems of high cost, poor safety, and low precision of manned helicopter inspections.

1. Fixed-wing visible light large-area inspection

By using fixed-wing aircraft to conduct large-scale inspections, it is possible to effectively discover the obvious faults of the line, the impact of natural disasters, and line theft; the cost is low, and the flight is safe on the line. disaster.

2. Unmanned helicopter thermal imaging and ultraviolet imaging inspection

Through the use of unmanned helicopters, equipped with high-precision thermal imaging and ultraviolet imaging equipment, under the condition of setting up a safe air corridor, carry out precise safety scanning along the line, and use thermal imaging to find out the internal strand breakage and line loss caused by the line. For local hot spots caused by the increase of resistive load, use digital transmission technology to transmit the data back to the ground station for real-time analysis to obtain a fault report; use ultraviolet imagers to detect micro-discharges caused by voltage differences caused by hidden insulation damage, and find out in real time For abnormal situations such as line damage, the monitoring situation is transmitted back to the ground station in real time through the transmission system, and a fault report is generated.

3. High-precision electric unmanned helicopter fixed-point hovering detection

After the detection by the above two methods, according to the detection report, the high-precision electric unmanned helicopter is used for fixed-point hovering detection of line faults, and thermal imaging and ultraviolet imaging are used to accurately detect line faults.

For traditional manual inspections and manned aircraft inspections, UAV inspections have obvious advantages such as high precision, high safety, high efficiency, and low operating costs.
