Functional Analysis of Infrared Thermal Imaging Inspection Robot for Outdoor Substation
Traditional substation inspection and maintenance relies on manual experience and manual operation, which have disadvantages such as high subjectivity, scattered inspection quality, and high labor intensity. With the continuous improvement of the intelligent level of the power grid, unattended substations introduce infrared thermal imaging inspection robots. The intelligent inspection operation reflects the advantages of being unaffected by weather factors and flexible control operation methods. It is better suitable for the inspection process of outdoor equipment in substations to ensure stable equipment operation and safe operation of substations.
Figure 1. Outdoor substation infrared thermal imaging inspection robot.
The infrared thermal imaging inspection robot for outdoor substations has the following ten functions:
(1) Inspection function
The infrared thermal imaging inspection robot realizes the regular inspection of the outdoor equipment of the substation at any set time, and can complete remote inspection, fixed-point inspection, temporary inspection and other operations.
(2) Detection function
The infrared thermal imaging inspection robot is equipped with pickups, infrared thermal imaging cameras, visible light cameras and other equipment, which can collect sound and video from the monitoring background, reduce or eliminate blind spots in video monitoring, and better improve the operating efficiency of the intelligent inspection robot.
(3) Infrared temperature measurement function
The infrared thermal imaging inspection robot can use the vehicle-mounted thermal imaging camera equipment to measure the joint temperature of all equipment in the substation, and perform fault alarms and information feedback to prevent the equipment in the substation from overloading and overheating.
(4) Machine vision recognition function
The infrared thermal imaging inspection robot can identify the data of the outdoor equipment and meters of the substation, and collect the image information of the outdoor equipment, such as: SF6 gas pressure value, switch opening and closing position, etc., and perform fault identification, storage and upload.
(5) Noise recognition function
It can extract noise characteristics based on the FFT principle, collect and analyze relevant data from different dimensions in the time domain and frequency domain, including the operating noise data of capacitors and transformers, determine the normal operation of the equipment, and perform fault signal warning and transmission.
(6) Microclimate big data collection function
The infrared thermal imaging inspection robot can collect the precipitation, wind speed, temperature and humidity data of the substation online in real time, and realize data analysis and report generation.
(7) Robot self-check function
The infrared thermal imaging inspection robot uses its independent self-inspection system to perform real-time self-inspection of the power supply, motor drive status, and communication status of the substation, and indicate and upload fault information on-site.
(8) Cluster deployment function
The infrared thermal imaging inspection robot can be adjusted and used in multiple substations to complete the corresponding inspection services.
(9) Safety protection function
The infrared thermal imaging inspection robot can use the ultrasonic radar detection method to intelligently detect obstacles, and is equipped with an anti-collision contact sensor to realize the automatic safety protection of the system.
(10) Autonomous charging function
The infrared thermal imaging inspection robot can self-check its own battery power status during the working process. When its battery power is insufficient, it will automatically terminate the current inspection task, send out an alarm signal, and autonomously enter the charging room to connect to the charging dock for charging.
