Embodiment Construction
[0029] Below in conjunction with accompanying drawing, invention and four kinds of specific wiring modes thereof are further described: the transmission lines in Fig. 1-4 are all single-circuit AC transmission lines, and it is made of a pair of insulated overhead ground wires arranged in parallel and one three-phase Wire composition.
[0030] Fig. 1 is a schematic diagram of the structure of the specific wiring mode of the first method of the present invention - the transposition wiring mode of the insulated overhead ground wire. The wiring method of reducing the induced voltage through the transposition of the insulated overhead ground wire is suitable for single-circuit transmission lines with short lines and no transposition of the whole line. The insulated overhead ground wire is grounded at one point, and the grounding point can be selected as one end of the insulated overhead ground wire. Or between the two ends, respectively, such as Figure 1a , 1b As shown, the speci...
