The invention relates to a method and a device for detecting an insulator through a multi-rotor unmanned aerial vehicle. The device comprises a multi-rotor unmanned aerial vehicle, as well as an onboard control computer of a flight control system, a positioning device, an unmanned aerial vehicle steering engine controller, a height measuring device, a speed measuring device, a high-definition camera, an unmanned aerial vehicle PCM (Pulse-Code Modulation) remote control receiver, an onboard wireless communication unit and a lifting device which are arranged on the multi-rotor unmanned aerial vehicle; the lifting device drives a probing lower pole to move; the onboard wireless communication unit communicates with a ground station; the unmanned aerial vehicle steering engine controller controls a servo steering engine; the servo steering engine controls a multi-rotor module; a probing upper pole and the probing lower pole are respectively connected with respective voltage sensors; the two voltage sensors are connected with an A / D (Analogue-to-Digital) conversion unit, a DSP (Digital Signal Processor) unit and the onboard control computer of the flight control system. The method and the device provided by the invention can be used for knowing and control the operation condition of a circuit insulator in time; the risk when a detector climbs up to carry out near-distance electrified operation can be further avoided; and meanwhile, the detection efficiency can be improved.
