Study on the relationship between electric field perception and distance factor of direct current overhead line

Abstract

The main reason for line collision accidents in offline construction is that construction personnel have an insufficient perception of distance. In the range of viewing angles, due to the lack of reference objects, people lack a correct judgment of the actual height of overhead lines. Voltage, as the most direct electrical volume, has always been a key indicator of electrical protection. In this paper, the feasibility of electrostatic induction is verified through the combination of electrostatic field simulation and experiment, and the influencing factors of electrostatic induction are studied. The results show that electrostatic induction is strongly related to the environmental angle, and the inductive voltage increases with the increase of the high voltage side, and the increased amplitude gradually increases. In addition, the induction distance and the shape of the receiving antenna have an impact on the effect of electrostatic induction. However, the induction distance has the greatest influence on the electrostatic induction effect, followed by the length and diameter of the induction conductor. The research of this paper plays a technical guiding role in the distance measurement of transmission lines based on electric fields.
