Embodiment Construction
[0030] The structure and principle of a ground wire energy storage device based on electromagnetic induction of the present invention will be further described below in conjunction with specific embodiments and accompanying drawings:
[0031] The ground wire of the transmission line is composed of two ground wires, which are the OPGW fiber optic composite ground wire grounded tower by tower and the ordinary ground wire with segment insulation.
[0032] The present invention uses the eddy potential induced in the ground wire as an energy source, and according to the principle of electromagnetic induction, the induced voltage of the OPGW ground wire around the transmission line is calculated as:
[0033]
[0034] Where: l is the span between the two towers, I A is the wire current, a is 120°, d 1a is the distance from the ground wire to the phase A conductor, d 1b is the distance between the ground wire and the phase B wire, d 1c It is the distance from the ground wire to ...
