Abstract

Abstract: In order to reduce the electrostatic induction effect of hybrid electric field generated by the UHV AC/DC parallel lines on residential houses and metal supports near the transmission corridor, this paper put up shielding wires paralleled to the AC/DC lines on the platform of residential buildings in the parallel to the AC/DC lines were established, and measured Distributions of the power frequency electric field and DC ionized field in parallel line direction were measured respectively, and the impacts of wires' height and number on the shielding effect on the hybrid electric field were also analyzed. And then built grape trellis metal support models for grape growing parallel to the AC/DC lines were set up, and the induced voltage distributions with different grid structures were measured. The results show that the shielding wires can effectively improve the spatial mixed electric ionized field under transmission lines can be effectively reduced by the shielding wires, and that has exist the best shielding structure of the wires also exists. The induced voltage of the metal support was greatly influenced by the support, and the maximum voltage value had no tingling sensation to the human body.

Key words: parallel power lines, hybrid electric field, electrostatic induction, shielding wires, shielding effect
