Abstract

A preparation method of an insulating material with high heat resistance comprises steps of weighing, preheating, mixing and cooling in sequence. The method has the following beneficial effects: goodheat resistant effect can be realized, stable electrical resistivity is guaranteed, especially in the presence of temperature gradient, charge injection under the action of a direct-current electric field can be inhibited, and local electric field is prevented from distortion.

Description

technical field [0001] The invention relates to the field of raw material preparation for insulating parts, in particular to a method for preparing insulating materials with high thermal resistance. Background technique [0002] During the operation of gas-insulated substation (GIS) and transmission pipeline (GIL), the temperature of the current-carrying busbar will reach 70°C or even higher due to the conduction current flowing through it. Injection volume increased. The injection of charges will not only lead to accelerated aging of insulating materials, but also cause distortion of the local electric field, thereby increasing the probability of surface flashover or internal breakdown of insulators during operation. This will be a big problem restricting the stable operation of GIS and GIL. Therefore, it is of great significance to develop a new type of epoxy resin with high thermal resistance as the epoxy substrate for internal insulation of GIS and GIL. Contents of t...
