Description

Technical Field

[0001] The present invention relates to the technical field of power equipment detection, and in particular to an expansion interface and a drone system for ultra-high frequency partial discharge detection drones. Background Art

[0002] At present, in the complex electromagnetic environment of the substation, the difficulty of diagnosing internal defects of the equipment has greatly increased. For the detection of ultra-high frequency partial discharge, if the traditional manual ground detection is used as the main detection method, a large amount of manpower and material resources will be invested. Not only is the detection efficiency low, there are blind spots in the detection process, but also the detection personnel will be exposed to high-risk areas, increasing the risk of injury. Therefore, drone detection has replaced manual ground detection and has become one of the main methods for detecting internal equipment in substations. At present, when using drones to detect ultra-high frequency partial discharge of substation internal equipment, since the detection equipment is simply installed on the drone, there is no signal interaction between the drone and the drone, resulting in the need for the data collected by the detection equipment to be transmitted through its own equipment. When ultra-high frequency partial discharge occurs inside the substation equipment, electromagnetic waves will be generated. The electromagnetic waves generated will affect the low-power wireless communication of the detection equipment, thereby affecting the signal sent back by the detection equipment, resulting in inaccurate detection results. In addition, since the communication power of the detection equipment itself is small and the transmission distance is short, it greatly affects the distance for the background staff to receive the signal. It can be seen that the existing drone detection has the problem of easy interference and short transmission distance during signal transmission. Summary of the invention
