"Machine Fish" trial sample machine.

On July 7, the transformer inspection of transformers developed by the State Grid Tianjin Electric Power Company's intelligent internal inspection "Machine Fish" through the performance test witness and acceptance of the domestic transformer industry experts marked the success of the "machine fish" research and development.

According to reports, the "machine fish" has functions such as image independent recognition, spatial autonomous positioning, three -dimensional path planning, and dive depth suspension. It can self -identify, quickly detect typical defects such as carbon marks and electrical branches discharge of large transformers. KMB and above transformers intelligent operation level.

"Machine Fish" can be used for internal status inspection such as the shift, deformation, overheating, discharge marks such as the shift, deformation, overheating, and discharge marks of large oil -soaked transformers. It has the advantages of small volume and flexible movement. It can conduct inspection without affecting the internal environment of the transformer. Whether there is an exception to improve the maintenance efficiency of the transformer. Liu Liqing, a R & D person in the Tianjin Institute of Electric Power Sciences, introduced: "'Robot Fish" can rotate at 360 degrees on the horizontal plane and has a comprehensive cruise capacity. It can independently plan the inspection path according to the set target points. When it is 2 meters per minute, the upward and sinking speed reaches 1.5 meters per minute. The depth hover error of the autonomous dive can be controlled within 3 cm. "

The "Robot Fish" was independently developed by the Tianjin Academy of Electric Sciences to rely on Guo.com Tianjin Electric Power Technology Project "The Research on key technologies for the internal defects in the internal defects of micro -machine fish". The project solves the problems of wireless positioning, wireless control, wireless image transmission in the transformer closed space in the closed space of the transformer, so that it can achieve flexible and accurate movement inside the transformer. The maintenance time, reducing the cost of maintenance, has good economic and social benefits.

It is understood that in the past, it was difficult to judge the internal abnormalities and parts of the transformer through external electrical tests and oil chromatography. The transformer was used to check or diagnose the suspension or abnormal diagnosis of the transformer, which often cost a lot of manpower and material resources. "Taking an abnormal 220 kV transformer as an example, the cost of oil inspection and processing is about 300,000 yuan, which takes about 10 days. Use the" machine fish "inspection. As a result, targeted maintenance measures are taken to minimize the maintenance time, reduce the cost of manpower, material resources and operating risks, and improve the reliability of transformers.
