Abstract

The invention provides a transmission and distribution line electric leakage real-time alarm positioning self-healing device which comprises an induction coil, an electric leakage alarm mechanism anda support, the induction coil is installed on a power transmission pole below a power transmission line cross arm, and the electric leakage alarm mechanism is installed on the support on the power transmission pole. According to the invention, the induction coil and a current alarm data transmission mechanism are installed on the power transmission pole; the real-time alarming of the electric leakage problem of the power transmission line is achieved, data are sent to maintainers or managers and a self-healing system, accurate analysis isolation or surrounding operation is achieved, the maintainers can arrive at an electric leakage positioning site in time, and potential safety hazards caused by the electric leakage of the power transmission line to surrounding personnel are prevented.

Description

technical field [0001] The invention relates to the technical field of power line safety protection, in particular to a real-time alarm, positioning and self-healing device for electric leakage of transmission and distribution lines. Background technique [0002] Transmission, distribution and transformation lines are erected on the ground and insulated by insulators and air. Overhead lines are exposed to the atmospheric environment and will be directly affected by meteorological conditions. At the same time, lightning strikes, rain, wet fog and Natural and industrial pollution will also damage or reduce the insulation strength of transmission lines and even cause power outages. Once leakage occurs during the use of transmission lines, since there is no monitoring device for transmission lines at present, the leakage situation of the transmission lines has not been reported to relevant maintenance personnel in time. If the leakage is not repaired in time, it will bring great...
