Problems solved by technology

[0002] In the natural environment, various dust particles in the atmosphere are attracted by the electric field force or gravity when passing through the insulator, and are deposited on the surface of the porcelain insulator, and the surface of the porcelain insulator is a hydrophilic glaze, and the surface smoothness is not enough. The surface is easy to accumulate dirt, and the shape and structure of porcelain insulators are also easy to affect the airflow when the wind blows, which usually leads to the accumulation of various flying dust

Embodiment 1

[0027] A method for preparing a novel anti-pollution type railway rod-shaped porcelain composite insulator, comprising the following steps:

[0028] (1) Preparation of the porcelain rod insulator body: first prepare the base material of the porcelain rod insulator body, then add water with a total weight of 30% of the base material to the base material to obtain a slurry, ball mill the slurry for 12 hours to obtain a new slurry, and then After the new slurry is sieved and iron removed, the mud is squeezed, and the obtained mud cake is extruded in a vacuum mud refiner, and the extruded mud section is then dried by electric shade, and finally shaped and dried to obtain a green body. Glazing, sanding, and firing to obtain a porcelain rod insulator body; the base material of the porcelain rod insulator body includes the following components, and the parts by weight of each component are: 4 parts of black clay, 40 parts of industrial alumina, 9 parts of Zhangcun soil, 14 parts of J...

Embodiment 2

[0034] It is basically the same as Example 1, except that the base material of the porcelain rod insulator body includes the following components, and the parts by weight of each component are: 3 parts of black clay, 45 parts of industrial alumina, Zhangcun 5 parts of soil, 20 parts of Jingyang soil, 5 parts of Zuoyun soil, 16 parts of Qingcaoling, 11 parts of white clay, 15 parts of feldspar, 1 part of Ninghai soil, 6 parts of Xinhui soil; lead antimony alloy in step (2) The glue is: Sb 5.0% by mass percentage, Sn 6.4%, and the rest is Pb; in step (3), spray silane coupling agent on the surface of the semi-finished product, and then heat it in an oven with a temperature of 40°C; in step (4) During the injection molding process, after the silicone rubber fills the mold cavity, it is kept at 150°C and 130bar clamping force for 60min.

[0035] The outer insulating shed sheath is composed of a large umbrella, a middle umbrella and a small umbrella, according to a middle umbrella ...

Embodiment 3

[0037] It is basically the same as Example 1, except that the base material of the porcelain rod insulator body includes the following components, and the parts by weight of each component are: 6 parts of black clay, 35 parts of industrial alumina, Zhangcun 12 parts of soil, 7 parts of Jingyang soil, 15 parts of Zuoyun soil, 7 parts of Qingcaoling, 20 parts of white clay, 5 parts of feldspar, 6 parts of Ninghai soil, 1 part of Xinhui soil; lead antimony alloy in step (2) The glue is: by mass percentage Sb 5.4%, Sn 6.0%, and the rest is Pb. In step (3), spray a silane coupling agent on the surface of the semi-finished product, and then heat it in an oven at a temperature of 60°C; Under the action of mold force, keep it for 30min.

[0038]The outer insulating shed sheath is composed of a large umbrella, a middle umbrella and a small umbrella, according to a middle umbrella with two small umbrellas, a large umbrella with two small umbrellas, several groups of a middle umbrella w...

Abstract

The invention discloses an antifouling type railway rod-shaped porcelain composite insulator. The antifouling type railway rod-shaped porcelain composite insulator comprises a porcelain rod insulator body, fitting accessories which are arranged at the two ends of the porcelain rod insulator body through adhesive, and an external insulating umbrella skirt sheath which is arranged on the exterior of the porcelain rod insulator body and is lap jointed with the fitting accessories, wherein the external insulating umbrella skirt sheath comprises big umbrellas, middle umbrellas and small umbrellas; and the umbrellas are arranged based on the sequences of one middle umbrella and two small umbrellas, one big umbrella and two small umbrellas, multiple groups of the one middle umbrella and two small umbrellas, and one big umbrella and two small umbrellas and one middle umbrella from the upper to lower. The antifouling type railway rod-shaped porcelain composite insulator has the advantages of high antifouling property, high self-cleaning property, high mechanical strength and long service life, so that the antifouling type railway rod-shaped porcelain composite insulator is suitable for coastal regions, saline and alkaline regions, windy and dusty regions, and regions with massive pollutants.

Description

technical field [0001] The invention belongs to the field of electric porcelain composite insulators, in particular to an anti-pollution railway rod-shaped porcelain composite insulator and a preparation method thereof Background technique [0002] In the natural environment, various dust particles in the atmosphere are attracted by the electric field force or gravity when passing through the insulator, and are deposited on the surface of the porcelain insulator, and the surface of the porcelain insulator is a hydrophilic glaze, and the surface smoothness is not enough. The surface is extremely easy to accumulate dirt, and at the same time, the shape and structure of porcelain insulators are also easy to affect the airflow when the wind blows, which usually leads to the accumulation of various flying dust. The specific composition of pollution varies with the region in which the insulator is located. However, it can be divided into water-soluble conductive substances and wa...
