Abstract: With the development of science and technology, robot technology is becoming more mature and perfect. Intelligent inspection robot is an innovative means to promote the intelligence of UHV grids. The emergency, difficult, dangerous, and repetitive tasks encountered in substation testing are performed by substation intelligent detection robots instead of manual work. Inspection robots can carry infrared thermal imaging cameras, visible light CCDs and other related substation equipment detection devices.
With the development of science and technology, robot technology is becoming more mature and perfect. Intelligent inspection robot is an innovative means to promote the intelligence of UHV grids. The emergency, difficult, dangerous, and repetitive tasks encountered in substation testing are performed by substation intelligent detection robots instead of manual work. Inspection robots can carry infrared thermal imaging cameras, visible light CCDs and other related substation equipment detection devices. They can inspect in various weather conditions and follow a fixed route to automatically identify thermal defects inside the power equipment, external mechanical or electrical problems. (Such as foreign objects, injuries, fever, etc.). Provides diagnostic power to the operator. Hidden dangers and failure precursor data during equipment operation. Through the man-machine interface, the historical temperature curve of the equipment is generated, the predictability of the equipment operating state is improved, and effective data support is provided for condition-based maintenance or condition assessment, thereby reducing the occurrence of accidents; the practical application of sound monitoring is continuously explored. Storage diagnostic system; continue to deepen and promote the operation and maintenance management model based on application robots, effectively improve the core management level.
Intelligent inspection robots independently start and complete inspection tasks based on preset inspection content, time, cycle, route and other parameters. During the special inspection, the operator selects the inspection content, manually starts the inspection, and completes the inspection tasks independently. Real-time remote video patrols are also possible. Can automatically open and close the charging door to complete self-charging. Equipped with infrared camera with auto-focus function. It can detect the temperature of the station equipment, automatically analyze and judge the defects or failures of current heating and voltage heating, and provide early warning; through the high-definition camera, it can read the data of the reading plate and the oil level gauge, automatically record and judge, and issue an alarm , The reading error is less than S less than 5%, with a pickup, can collect equipment operating noise. Can collect ambient temperature, humidity, pressure, precipitation, wind direction, wind speed, etc. Information such as visual images, infrared images, sound meter readings, equipment position status, and equipment oil levels collected during the inspection task are stored in the inspection database. Automatically generate equipment defect reports, inspection task reports, etc., and provide historical curve display. All reports have query capabilities.
The importance of intelligent inspection robots in power systems is unquestionable. The continuity of use, the safety of production, transportation and power distribution all have high requirements. With the rapid development of the power industry toward large units, large capacity, and high voltage, ensuring the reliability of equipment operation has become a prominent issue in safety production. Therefore, the detection of power equipment, especially the application of some advanced technologies, methods and methods in equipment fault diagnosis, is receiving more and more attention, and the economic benefits obtained are becoming more and more obvious. In the scope of application, intelligent inspection robots are mainly used for unattended or unattended substation inspections to better replace inspection inspection concepts. The widespread application of patrol robots can reduce the utilization rate of personnel and the loss of some human factors, thereby speeding up the speed and quality of the power grid. In this way, the use of inspection robots can better reduce the personnel cost of the power supply system and improve the operating efficiency of the power supply system. Especially in some substations with harsh natural environment, such as the geographical conditions are more complex, far away from the town, intelligent robots are more commonly used in these places.
