摘　　要：温升是影响垂直接地极运行特性的一个重要因素,为了对垂直接地极的温升特性进行研究,通过研究多根垂直接地极等间距环形布置时接地极的温升特性,确定了电极之间温升影响的作用范围,提出了温升的简化计算模型。在无法对整个垂直接地极进行有效建模的情况下,可搭建垂直接地极温升的简化计算模型,实现接地极温升的仿真计算研究。Temperature rise is an important factor affecting the operating characteristics of vertical grounding pole.In order to study the temperature rise characteristics of the vertical grounding pole,this paper determines the range of influence of the temperature rise between the electrodes,and proposes a simplified calculation model of the temperature rise by studying the temperature rise characteristics of the grounding pole when multiple vertical grounding poles are arranged in a ring with equal spacing.In the case that the whole vertical grounding pole cannot be effectively modeled,the simplified calculation model of the temperature rise of the vertical grounding pole can be built to realize the simulation calculation of the temperature rise of the grounding pole.
