摘　　要：针对传统的高压输电线下的危险电场预警仪主要根据单一的电场值的阈值来进行危险电场的预警,存在易受单一传感器的影响,受环境影响大,以及预警不稳定等问题,基于模拟电荷法,通过仿真分析,研究了同一高压输电线下的高度差值和电场差值之间的关系,得出了一种同时基于电场值和电场差值的电场预警机制,从而提高了预警的准确性和稳定性。During the maintenance of high voltage transmission line circuit, professional workers face live working inevi- table. In order to ensure the safety of occupational workers, produce a variety of dangerous electric field warning device. The conventional danger warning device field under high voltage transmission lines is mainly based on a single threshold elec- tric field values for early warning in the dangerous electric field. The disadvantage of such a warning is susceptible to this single sensor, subject to environmental impact, warning instability and so on. Based on the charge simulation method, ana- lyze the relationship between the difference of the electric field and the height of the high voltage transmission lines. The re- sult can improve the warning accuracy and stability.
