摘　　要：本文以并联间隙地线绝缘子为研究对象，针对电气系统地线直流融冰的需要，对带并联间隙装置的地线绝缘子进行了覆冰闪络仿真实验研究，分析验证了并联间隙距离与绝缘子闪络电压、覆冰水电导率与绝缘子闪络电压之间的关系，为我国电力行业在地线直流融冰中绝缘子与并联间隙的配合提供理论指导。In this paper, the parallel gap ground wire insulator is taken as the research object; aiming at the need of DC cooling of the electrical system ground line, the experimental study on the overlay of the ground insulator with parallel gap device is carried out. The relationship between the parallel gap distance and the flashover voltage of the insulator, the conductivity of the ice water and the flashover voltage of the insulator is verified, which provides theoretical guidance for the cooperation of the insulator and the parallel gap in the power line in China.
