Problems solved by technology

The construction method seriously threatens personal safety and causes serious environmental pollution.
The State Grid stipulates that its service life is only 5 years. After 5 years, the surface coating of the insulator needs to be removed first, and then recoated. The labor intensity is high, the cost of power outage is high, the labor cost is high, and the service life is low.

Embodiment 1

[0025] High-strength silicone-silicon rubber disc-shaped suspension porcelain and glass composite insulators, the specific processing methods are:

[0026]1. Select the body according to customer requirements, then prepare the raw materials for base rubber processing, and then put the raw materials into a high-speed mixer. In the high-speed mixer, the base rubber is mixed with processing aids and fillers. The speed of the mixer is 300-1000r / min. The temperature should not exceed 80 degrees to avoid gelation when mixing with the crosslinking agent and catalyst in the next step. The charging coefficient in the mixer is controlled at 10%-30% by the outlet pressure, and the rubber material after continuous feeding and mixing is continuously discharged.

[0027] 2. The prepared rubber compound is continuously sent to the material tank under reduced pressure. The material tank is continuously degassed and thixotropic agent is added. The vacuum of the material tank is controlled belo...

Embodiment 2

[0032] In the base glue coating of the present invention, on the basis of the base glue hydroxyl glue, adding a certain proportion of phenyl can improve the high and low temperature resistance performance of the coating. The addition of trifluoropropyl group and cyano group can improve the temperature resistance and oil resistance of the coating. It can work normally in the range of minus 70 degrees to 180 degrees. Fumed silica is one of the reinforcing agents for the coating, and the rubber compound reinforced by it has high mechanical strength and good electrical properties. When the phenyl content is 20-40%, it has excellent flame retardancy, and when the content reaches 40-50%, it has excellent weather resistance and radiation resistance. The coating contains a certain proportion of methyl phenyl vinyl components, so that it has a wide temperature range, oxidation resistance, good weather resistance electrical insulation properties, but also has excellent low temperature ...

Abstract

The invention provides a high-strength organic silicone rubber disc-shaped suspension type porcelain and glass composite insulator which is characterized by comprising a body and base rubber, the surface of the body is wrapped with the base rubber, and the base rubber is polyalkyl aryl organic composite high-strength silicone rubber. Silicone rubber is improved, base rubber components of the silicone rubber are changed, and the silicone rubber is novel silicon resin silicone rubber which is high in performance, long in service life and high in strength, especially has very important practical significance in antifouling work of ultra/extra-high voltage power grid lines, and can be used for improving the antifouling performance of the ultra/extra-high voltage power grid lines on the premise that safe operation of a power system is guaranteed. A large amount of construction investment and operation maintenance cost are saved, and social benefits and economic benefits are remarkable.

Description

technical field [0001] The invention relates to the field of electric power transmission, in particular to a high-strength organosilicon-silicon rubber disc-shaped suspension porcelain and glass composite insulator. Background technique [0002] With the rapid development of industrial and agricultural production, on the one hand, the air pollution is becoming more and more serious, the pollution is increasing, and the environment is deteriorating. As a result, pollution flashover accidents in the power system continue to occur, involving a wide range and long power outages, which seriously threatens the safe operation of the power system and power transmission and transformation equipment, and at the same time brings significant economic losses to the national economy. Every winter, thousands of pollution flashover trips occur in the national power grid, sometimes jeopardizing the safety of provincial power grids. There are also serious implications for the increasingly st...
