[0003] In the test process of high -voltage power grid unmanned operation platform, when high -voltage power grid unmanned operation platform is driven by the unmanned plane to approach / leave high -voltage transmission line, the complex wire on high -voltage power grid unmanned operation platform will cut high -voltage transmission line, thereby generating reverse current and transmitting to the controller, taking the wire connected to the driving element as an example, the driving element is directly connected to the IO port on the controller through the wire in the initial design, and the IO port is the most fragile part on the controller, and the voltage that it can withstand does not exceed 3.3V, and the current does not exceed 3mA. When high -voltage power grid unmanned operation platform approaches / leaves high -voltage transmission line, the connection wire of driving element and IO port will generate reverse current due to cutting the magnetic field around high -voltage transmission line, and transmit to the IO port, causing IO port to appear short circuit / open circuit and other damage abnormalities. Once the IO port has a problem, it means that the controller can no longer control the driving element, resulting in that high -voltage power grid unmanned operation platform cannot normally walk on high -voltage transmission line. Therefore, the line of high -voltage power grid unmanned operation platform needs to be re-adjusted, and a device capable of preventing the reverse transmission of current generated by cutting high -voltage wire electromagnetic field to the controller is designed.
