The invention discloses an unmanned aerial vehicle zero-value insulator detection method and system combined with a neural network. The method comprises the following steps: acquiring radial electric field amplitudes of different positions of an insulator from an unmanned aerial vehicle side; inputting the obtained radial electric field amplitude and the position of the detection point corresponding to the radial electric field amplitude into a BP neural network for iterative training, and fitting a radial electric field distribution diagram of the insulator by using the trained BP neural network; and performing zero-value insulator detection according to the insulator radial electric field distribution diagram. The method is applied to overhead line live inspection work, and on the premise of ensuring safe and stable operation of a power system, the electric field distribution around the insulator is measured through a non-contact detection method under the live working condition, so that the existence condition of the zero-value insulator is identified, timely troubleshooting and replacement of the zero-value insulator are ensured, and the working efficiency is improved. And the method has good social and economic benefits.
