Abstract

Abstract: With the continuous in-depth application of unmaned aerial vehicle(UAV) in substation inspection work, reading of oil level/meter equipment such as current transformers (CT), transformers, and circuit breakers has become an urgent need. The current UAV inspections with manual flight operations, or with isolated network by manually exporting inspection image, have not been integrated with the intelligent inspection system of the running private network in the substation. Taking the construction of the UAV inspection system in the substation as the starting point, this article decomposes the components of the UAV inspection system in the substation and analyzes the various functional modules. Based on the communication protocol and network topology of UAV, airports, and third-party platforms, two private network access methods of wired network and wireless network are discussed. The actual application of the substation site verifies the feasibility and effectiveness of the scheme, and realizes the autonomous inspection of the 500 kV CT oil level by the UAV. The inspection accuracy and inspection efficiency are better than those based on high-definition video inspection technology.

Key words: substation, UAV inspection system , current transformer, oil level meter, network topology, private network communication
