The Research of Equipment Electricity Identification of UHV Power Transmission and Transformation Based on Electrochromic Material

Abstract

Now, electroscope has disadvantage of large quality, inconvenient operation, and it has low quality of accuracy, adaptability, reliability and cost performance. In this paper, a new method for the identification of electricity test is presented. It uses electrochromic material for equipment electricity identification of UHV power transmission and transformation. When the device is charged, the material will change color as the charged signal; while the device is not charged, the material will return to the original color. The material has advantage of low energy consumption, no radiation, apparent identity, repeated use. This paper adopted three kinds of materials such as tungsten trioxide material, Ag-Polybutene (hereafter referred to as PB) composite material and graphene-Polyamide (hereafter referred to as PA) for production making and test. The results show that these three kinds of material have electricity identification performance, the properties of graphene-PA composites were the best, and it has the development prospect as eletrochromism material used for equipment electricity identification of UHV power transmission and transformation.
