The utility model provides an electric field induction system of stallling, includes: non -contact tests the electric installation for gather power transmission line electric field signal all around, work as electric field signal's intensity is greater than when predetermineeing intensity, and output is used for signifying the electric flame -out signal of having of power transmission line electrification, the controller is used for the basis there have the flame -out signal control engine of electricity to be flame -out. Thereby realized the large -scale davit that lifts by crane equipment such as hoist, crane when being close to live -line line, engine automatic flameout, and then, automatic time -out operation, the comparatively effectual safety of guaranteeing operating personnel.
