Abstract

The invention discloses an insulating part. The insulating part comprises an insulating casting body, n insulating layers are arranged in the insulating casting body, the insulating layers are sequentially arranged in a stacked mode, and the insulating layers are formed by mixing resin base materials and filling materials in different proportions, so that the dielectric property in the insulatingpart is changed in a gradient mode, wherein N is greater than or equal to 2. The invention also discloses a preparation method of the insulating part. The preparation method comprises the following steps: adjusting the ratio of the resin base material to the filling material; uniformly mixing the resin base material and the filling material according to the proportion to form a composite material;injecting the composite material into a mold, and carrying out microwave curing to form an insulating layer; repeating the above steps until N insulating layers are formed; wherein N is greater thanor equal to 2. According to the invention, the problem of non-uniform electric field around the insulating part in the prior art can be effectively solved, the gradient characteristic inside the insulating part and the surrounding electric field can be regulated and controlled, and the uniformity of the electric fields inside and around the insulator can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of insulating devices, in particular to an insulating part and a preparation method thereof. Background technique [0002] Insulators of power equipment (such as pot insulators for gas-insulated switches, transformer bushings, cable accessories, and line suspension insulators) play key roles in insulation, electrical isolation, uniform electric field, and mechanical support. However, according to the operation and maintenance of power grid companies The data shows that the insulation parts of power equipment are facing the problem of frequent failures. At present, the failure of insulation parts of power equipment has become the most important cause of failure of power equipment. [0003] The inhomogeneous electric field around the insulating part is the main cause of insulation failure of the insulating part. For example, in a gas insulated switch, there is a concentration of electric field at the three ju...
