摘要：
Realizing the controllable charge of the gas-solid interface can improve the stable operation performance of the insulation under DC voltage, and the characteristic parameters of the gas-solid interface of DC gas insulated transmission line(GIL) have a great influence on the charge behavior. In this paper, the factors affecting the charge behavior of DC GIL gas-solid interface in the past 40 years were sorted out. Secondly, based on the previous detailed summary of the charge tailoring techniques of the gas-solid interface, a "layered" system for the dielectric properties of DC GIL gas-solid interface was proposed. Relying on the horizontal and vertical analysis of the system, the factors involved in the charge tailoring techniques, the characteristics of surface charge dissipation, and surface flashover were combined to establish a causal relationship between each other. By discussing some of the controversies involved in some research, it was pointed out that there may be two routes for suppressing flashover, "evacuation charge" and "trapped charge". Finally, this paper looked forward to the future research in the field of direct current gas-solid interface charge regulation. In terms of basic theory, it is necessary to build a more comprehensive and detailed cognition system of DC GIL gas-solid interface charge transport from the combined effect of multiple influencing factors. In terms of product research and development, it is essential to achieve industrial applications as the goal, and find the current limitations and improvement directions in charge tailoring research. © 2021 Chin.
