Embodiment Construction

[0031] see figure 1 As shown, the present invention is based on the 3D printing conductivity gradient polymer insulator manufacturing method, which specifically includes the following steps:

[0032] Step 1: Construct a 3D CAD model of the insulator geometry and conductivity spatial distribution, divide the model into multiple geometric units and generate the STL file of the model, use the slicing software to simulate the 3D CAD model defined by the STL file according to the preset layer thickness Divide it into different layers, calculate the printing trajectory of each layer, and finally get the G-code control file required by the 3D printing device.

[0033]Step 2: Use the three-dimensional finite element method to calculate the electric field distribution inside and on the surface of the insulator, and obtain the spatial distribution of the conductivity of the insulator according to the actual electrical characteristic requirements of the insulator. Specifically, the insi...

Abstract

The invention belongs to the field of manufacturing of high-voltage equipment, and discloses a 3D printing-based manufacturing method for a conductivity gradient polymer insulator. The method comprises the following steps: (1) three-dimensional modeling for the insulator and model slicing; (2) conductivity space distribution calculation; (3) raw material preparation; (4) mixing ratio calculation; (5) 3D printing of the insulator; and (6) post-treatment. Compared with a centrifugal manufacturing technology, according to the 3D printing-based manufacturing method for the conductivity gradient polymer insulator disclosed by the invention, the conductivity space distribution of a multi-dimensional insulator material can be achieved; and the targets of flexibly regulating and controlling internal and superficial electric field intensities of the insulator under direct-current voltage and improving the breakdown voltage of the insulator are reached.

Description

【Technical field】 [0001] The invention belongs to the field of high-voltage equipment manufacturing, and in particular relates to a method for manufacturing an electrical conductivity gradient polymer insulator based on 3D printing. 【Background technique】 [0002] There has been an imbalance between energy resources and load centers in my country for a long time. The overall distribution of energy resources presents the characteristics of "more in the west and less in the east, more in the north and less in the south", while the load centers are mainly concentrated in the eastern and central regions. With the rapid growth of power demand and the increase of environmental pressure, the country and society have increasingly urgent requirements for long-distance, large-capacity, and high-efficiency power transmission methods. EHV / UHV DC transmission is especially suitable for long-distance and ultra-long-distance power transmission due to its advantages of less line investment,...
