Problems solved by technology

Heilongjiang Province is located in the high-latitude cold region of northern my country, where the annual minimum temperature can reach below -45°C. Most of the transmission line corridors pass through mountainous areas, covered with ice and snow for a long time, making it difficult to inspect the line, especially in the event of lightning strikes or internal overvoltages When the power system fails, it will bring a lot of pressure to the troubleshooting and maintenance work
Traditional transmission line fault inspection methods mainly rely on manual inspection or tower inspection. Under the influence of extremely low temperature and complex terrain in Northeast China, the accuracy and efficiency of manual inspection will be greatly reduced, and there are also cooperative inspections such as drones. Certain limitations seriously affect troubleshooting efficiency

Abstract

The invention discloses a silicone rubber composite material with an electrochromic property. The silicone rubber composite material is prepared from the following raw materials: methyl vinyl raw rubber, hydrophobic fumed silica, zinc stearate, hydroxyl silicone oil, magnesium hydroxide, aluminum hydroxide, a vulcanizing agent and transition metal oxide materials (tungsten oxide, titanium dioxide, nickel oxide and vanadium pentoxide). The invention relates to a preparation method of a silicone rubber composite material with electrochromic performance. The preparation method comprises the following steps: mixing a filler and a matrix, carrying out first-stage vulcanization on a flat plate, carrying out second-stage vulcanization on an electric heating box and carrying out performance testing. The prepared silicone rubber composite material has electrochromic performance, and the silicone rubber added with the transition metal oxide is high in structural strength, strong in viscosity and good in dielectric property, and can meet the use requirements of insulator materials.

Description

technical field [0001] The invention relates to the technical field of silicone rubber materials, in particular to a silicone rubber material with electrochromic properties and a preparation method thereof. Background technique [0002] In my country's power system, composite insulating materials are widely used. Insulators play the role of fixing, supporting and insulating in high-voltage power transmission and distribution. The application rate of composite insulators is increasing year by year. In the past 15 years, new grid insulators are basically composite insulators. The composite insulator has the advantages of light weight, good anti-fouling performance, and strong anti-human damage performance. Under the action of the external environment, electric field and magnetic field, the aging of composite insulators is accelerated, which not only affects the stability of power transportation, but also has potential safety hazards. Especially in high altitude, cold and humi...
