Method and device for measuring icing of power transmission line in real time

The invention discloses a power transmission line icing real-time measurement method and a measurement device. The method comprises the following steps: selecting an eight-cylinder ice accretion device as a measurement device and determining structural parameters; in the non-icing period, the base of the measuring device is installed on a target line tower through a bolt fixing piece; when natural icing is formed for the first time, the eight-cylinder ice accretion device drives cylinders to rotate and work through a motor at the bottom, the icing quality is measured in real time, atmospheric icing parameters are inversely calculated, and a result is recorded; when the power transmission line starts to be subjected to manual ice melting, the device receives a line ice melting current value and an ice melting operation starting signal, and cylinders A1-A4 of the eight-cylinder ice accretion device are heated through the control module; according to the icing mass measured in real time, the icing increasing wei
