A robot suitable for electromagnetic adsorption and climbing on the inner wall of oil-immersed transformer

Abstract

The invention discloses a robot suitable for electromagnetic adsorption and climbing on the inner wall of an oil-immersed transformer. system. The invention is small in size and can be observed deep inside the transformer; it has electromagnetic adsorption ability, can be adsorbed on the wall and overcome gravity to achieve climbing; adapts to the complex special environment inside the transformer, and can flexibly climb over prominent structural obstacles; carries a high-definition universal camera , can accurately determine the type and location of transformer faults; remote control operation will not cause pollution to the transformer due to personnel entering; reasonable structure, reliable performance; reduce the workload of maintenance personnel and improve work efficiency.

Description

technical field [0001] The invention relates to a robot suitable for electromagnetic adsorption and climbing on the inner wall of an oil-immersed transformer, which belongs to the technical field of transformer maintenance equipment. Background technique [0002] As an indispensable part of the power system, the transformer in the substation plays a pivotal role in the safe and stable operation of the power grid. The application of transformers can not only ensure the safe and efficient operation of the distribution network, but also adjust the power supply according to the demand to achieve the optimal configuration of power supply. Therefore, the internal or external failure of the transformer will bring serious consequences to the system, ranging from short-term power outages in small areas to severe negative impacts on production and life, and even triggering strong social repercussions, which may cause chain-like other adverse consequences. [0003] When common power ...

AI Technical Summary

Problems solved by technology

However, it takes a lot of work to manually enter the transformer through the manhole set on the transformer for investigation, because the internal space of the transformer is small, there are many places inside the transformer that personnel cannot reach, and it is easy to cause pollution due to manual entry.

Since the above-mentioned maintenance methods cannot accurately determine the type and location of the fault, it is easy to cause a lot of waste of manpower and material resources; increase the frequency and time of power outages of the transformer; increase the possibility of new equipment hidden dangers during the maintenance process; The overall service life is reduced; problems such as increasing the difficulty and cost of transformer maintenance

So far, there are no literature reports and practical applications on the robot system that can electromagnetically absorb and climb the inner wall of oil-immersed transformers
