Wheeled intelligent traction substation patrol robot "works" at the 110 kV unattended substation of Hargai on the Sige line of the Qinghai-Tibet Railway at an altitude of 3300 meters. Its birth marks that the inspection method of the unattended substation of the Qinghai-Tibet Railway has entered a new era of remote intelligent control. More and more intelligent equipment will be applied to the railway and high-speed rail industries to open up a new future for railways.
The robot is equipped with visible light cameras, infrared thermal imagers and sound acquisition and other detection equipment, with trackless positioning and navigation functions, which can replace the inspection personnel to carry out daily inspections of the equipment in the traction substation, and can also carry out emergency inspection work in unexpected situations.
Disadvantages of manual inspection
The Qinghai-Tibet Railway has a high altitude, a harsh natural environment, and poor road conditions leading to the unattended substation. Xining power supply section arranges special personnel to inspect the unmanned substation twice a month, and it takes two days to inspect a trip, with high labor intensity, low work efficiency, scattered testing quality, and difficult night inspection, and single inspection means.
In addition, under bad weather conditions such as thunderstorms, manual inspection has great safety risks and cannot be inspected in time.
Advantages of intelligent inspection
How it works
Intelligent robot inspection through the pre-setting of multiple monitoring points, from multiple angles of the whole station equipment for overall scanning temperature acquisition, the system can be transformer, transformer and other equipment body and the temperature of each switch contact, bus connector, etc., and the use of temperature rise analysis, similar or three-phase equipment temperature rise comparison, historical trend analysis and other means, intelligent analysis and diagnosis of equipment temperature data, to achieve the identification of equipment thermal defects and automatic alarm.
Inspect the content
The inspection content of the power inspection robot includes equipment temperature, equipment appearance, knife gate opening and closing status, instrumentation, equipment noise, etc.
Infrared general test
Intelligent robot on the equipment for a full range, multi-angle detection and diagnosis, accurate temperature measurement, for the same equipment, each time can achieve a high degree of consistency in position, angle, configuration parameters, to ensure the accuracy and effectiveness of temperature detection.
Defect tracking
The power inspection robot automatically tracks and monitors the defective equipment in real time, and the operation and maintenance personnel remotely control the defective equipment through the terminal and select the equipment defect tracking option to achieve real-time data collection of the defective equipment. At the same time, the power inspection robot also has the functions of saving data, analyzing data changes, and uploading data reports.
The promotion of intelligent substation and unattended substation mode puts forward higher requirements for substation inspection. The entry of "Wali" into the Qinghai-Tibet Railway is a specific measure of the Qinghai-Tibet Group Company to adapt to the reform of the repair process and build a smart heavenly road, providing a more reliable power supply guarantee for the safe transportation of the Qinghai-Tibet Railway.
