Abstract:  In the modern power grid system, in order to ensure the reliability of its power supply, power workers are often required to perform live operations. The fault arc will release high temperature through radiation, which is very easy to cause damage to the live workers, surrounding electrical equipment and lines. Therefore, it is of great practical significance to study the physical properties of arcs and arc protection. Insulating materials have excellent physical properties such as high temperature resistance, high strength, and high toughness, and can be used in the field of arc fault protection. Commonly used insulating materials for arc protection include polyimide, aramid, acrylic, etc. In this paper, the influence of arc fault on polyimide insulating material is studied by comparing the mode of experiment and simulation. The COMSOL software was used to simulate the process of arc affecting polyimide insulating material, and the physical field distribution of the arc was obtained by changing the electrode spacing and arc current. An experimental platform for polyimide insulation materials affected by arcs was established. The platform was equipped with a copper calorimeter to record the temperature rise of each experiment, and various arc parameters were changed to summarize the laws of arcs affecting insulation materials. The conclusion shows that the polyimide insulating material can effectively block the high temperature of the fault arc under different arc states, indicating the importance of polyimide insulating material in modern power grid systems, and can be used as an important component of arc protection fabrics part.
