Transformer substation operation inspection robot and electrified area isolation method thereof

Abstract

The invention discloses a transformer substation operation inspection robot and an electrified area isolation method thereof, and aims to solve the technical problem that an electrified area is difficult to isolate accurately in the transformer substation operation inspection process. The robot comprises a robot body and an electrified area isolation device, the electrified area isolation device comprises an ultrasonic sensing module, an image recognition module, an electric field measurement module, a sound-light alarm module and a control module, a robot action route is planned according toultrasonic ranging, electric field ranging and image recognition, and the robot is controlled to give an alarm or be locked. According to the invention, the electrified area of a transformer substation can be actively isolated, the overall intelligent level of inspection equipment in the power industry is improved, the personal safety of operators is ensured, and the power failure maintenance timeis shortened.

Description

technical field [0001] The invention relates to a substation operation inspection robot and a live area isolation method thereof, belonging to the technical field of substation intelligent operation inspection. Background technique [0002] Relay protection device verification and primary equipment electrical test are necessary tasks in the substation to ensure the safe and stable operation of the power grid. They need to be carried out when the primary equipment is powered off. The test instruments are precision instruments that usually weigh 30-40kg. In the process of substation maintenance, the test equipment is generally transported by artificial or extremely low-level intelligent transportation equipment. This type of transportation has the following shortcomings: [0003] (1) The electrical environment in the substation is complex, the blackout area and the live area intersect each other, the existing transportation equipment does not have the hardware structure and me...

AI Technical Summary

Problems solved by technology

[0003] (1) The electrical environment in the substation is complex, the blackout area and the live area intersect each other, the existing transportation equipment does not have the hardware structure and method for isolating the live area, operators are easy to enter the live area by mistake, and there are great safety hazards during work;

[0004] (2) At present, the methods of isolating live areas used in substations include: manually setting up physical fences, live induction isolation methods, etc. Setting up physical fences requires a lot of manpower and material resources, and there is a certain risk of erroneous entry (such as fence collapse, etc.), for For conventional transportation equipment, the single charged induction method determines the charged area through the induced electric field strength, which has shortcomings in accuracy;

[0005] (3) The circuit part of the existing transportation equipment is simple and does not have the ability of customized power supply. Due to the limitation of the station environment, the power can only be obtained from the external power line of the power box at a fixed position, and the output power of different types of instruments needs to be considered. The test work is often affected by external interference, which takes up a lot of power outage maintenance time
