Research on the Technology of UHV Converter/Transformer Live Oil Sample Collection Robot for Safe Operation

This article designs an automatic oil sample collection robot for UHV AC transformers and converter transformers, which is used to replace operation and maintenance personnel in completing automatic oil sample collection. Firstly, by reasonably modifying the transformer oil outlet and leading it out to the road surface, the problem of robots crossing the unloading pool and entering the Boxin was solved; Secondly, the mobile mechanism, chassis structure, and transmission mechanism of the robot body were designed, combined with a simple and reliable robot navigation and positioning method to achieve rough positioning of the robot's autonomous navigation to the oil intake. Then, an auxiliary positioning device was used to ensure that the sampling syringe was aligned with the oil intake; Finally, an automatic oil sampling device was developed, including an oil sampling mechanism, a flipping mechanism, a gripping mechanism, and a cap mechanism, achieving automatic collection of transformer oil samples based on robot carriers.
