Abstract

The invention discloses an insulating overhead ground wire based power taking apparatus. The power taking apparatus comprises an auto-transformer, a filter, an electric air valve, an air pressure adjusting valve, a pneumatic motor and a generator, wherein the auto-transformer is connected with one section of a wire for obtaining a first current, and used for performing voltage transformation processing on the first current to obtain a second current; the filter is connected with the auto-transformer and used for filtering the second current to obtain a third current; the electric air valve is connected with the filter and used for generating first air flow based on the third current; the air pressure adjusting valve is connected with the electric air valve and used for performing voltage stabilization based on the first air flow and then outputting steady second air flow; the pneumatic motor is connected with the air pressure adjusting valve and the pneumatic motor rotates based on the second air flow; and the generator is connected with the pneumatic motor and generates current based on the rotation of the pneumatic motor. Due to the induction current-mechanical energy-current conversion of the insulating overhead ground wire, the problem that unstable current is caused by the changes of the induction current along with changes of transmission loads and external environments of power transmission lines due to the reason that the ratio of transformation of the auto-transformer cannot be high is solved.

Description

【Technical field】 [0001] The invention relates to the field of electric power, in particular to a power-taking device based on insulated overhead ground wires. 【Background technique】 [0002] According to the current domestic electric power capacity estimation, the national annual electric energy loss will reach tens of billions of kWh. Part of the electric energy is lost by the overhead wire, and most of the induced current flows into the earth from the overhead ground wire. [0003] There are electrostatic coupling and electromagnetic coupling between the overhead ground wire and the transmission line. Under normal circumstances, the induced voltage and current on the ground wire mainly change with the distance from the ground wire to each phase wire, the load current on the three-phase wire and the asymmetry of the wire. And change. The grounding method of the ground wire can be divided into: 1) The ground wire and the OPGW are grounded base by base; 2) The ground wire ...
