Weiguang Zu, Zhichao Li and Lei Nie

With the continuous improvement of science and technology, the substation patrol inspection has gradually stepped into the unmanned stage or the less humanized stage. Although the input of patrol robot improves the intelligence and modernization of substation patrol work, it also gives rise to some problems that are not favorable to the work of patrol robot, such as loose or bad contact of wired charging interface, copper oxidation at the electric end, etc., which restrict the normal work of substation patrol robot. Based on this, in order to avoid the occurrence of such problems, the core algorithm of electromagnetic resonance wireless charging technology is studied. To be specific, the existing wireless charging technologies are compared by comparison method, and magnetic resonance is finally chosen as the wireless power supply method in this paper, and then the design scheme of wireless charging device is given. Finally, the calculation method of coupling system efficiency and system output efficiency is given through the test of magnetically coupled resonant wireless charging efficiency. It is also pointed out that the radio energy transmission efficiency is affected by the coil distance, resonant frequency and the number of turns of the receiving coil. It can be seen that in practical engineering, we can focus on these factors to improve the efficiency of radio energy transmission and promote the work progress and efficiency of substation patrol robot. This research aims to promote the overall popularization of wireless charging technology for substation robots.
