Robot suitable for inner wall of oil-immersed transformer and capable of achieving electromagnetic adsorption and climbing

Abstract

The invention discloses a robot suitable for an inner wall of an oil-immersed transformer and capable of achieving electromagnetic adsorption and climbing. The robot comprises an electromagnetic adsorption type robot and a remote controller, the electromagnetic adsorption type robot is in communication connection with the remote controller, and the electromagnetic adsorption type robot is providedwith a fault camera system. The robot is small in size and can go deep into the transformer for observation; the robot has an electromagnetic adsorption capacity, can be adsorbed on a wall surface and overcomes gravity to realize climbing; the robot adapts to a complex special environment in the transformer, and can flexibly climb over prominent structural obstacles; a high-definition universal camera is carried so that a fault type and a position of the transformer can be accurately judged; remote control is achieved, and pollution to the transformer due to personnel entering is avoided; thestructure is reasonable and the performance is reliable; and a workload of maintainers is reduced, and working efficiency is improved.

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
