摘要 

目前在中、高压气体绝缘输配电设备中大量使用的SF6是一种极强的温室气体。为实现“2030年碳达峰,2060年碳中和”的减排目标,推进输配电装备制造业清洁低碳转型和绿色发展,开发环保型气体绝缘介质及设备以逐步减少SF6的使用已成为研究热点。近年来,全氟异丁腈(C4F7N)及其混合气体凭借优良的绝缘及环保性能被广泛关注,被认为是极具潜力的SF6替代气体。该系列文章综述了近五年来国内外有关环保绝缘气体C4F7N的主要研究成果。本文综述Ⅰ首先介绍了常见环保绝缘气体基础参数;其次对C4F7N混合气体的绝缘和灭弧特性研究进展进行了总结;最后介绍了C4F7N的电、热分解机理及分解特性,并展望了未来针对绝缘性能及电、热分解特性的研究趋势。

Abstract

Sulfur hexafluoride (SF6), which is widely used in medium and high voltage gas insulating transmission and distribution equipment, is an extremely strong greenhouse gas. In order to achieve the emission reduction goal of “carbon peak in 2030, carbon neutral by 2060” as well as promote the clean, low-carbon transformation and green development of the power industry, developing eco-friendly gas insulating medium and equipment to gradually reduce the use of SF6 has become a hot topic. In recent years, Perfluoroisobutyronitrile (C4F7N) and its gas mixture have attracted wide attention due to its superior insulation and eco-friendly properties, which demonstrates promising application potential as SF6 alternative gas. In this series, we summarized the research status of eco-friendly gas C4F7N at home and abroad over the past five years. In part I, the basic parameters of common eco-friendly gases were firstly introduced. Then the research progress of insulation and arc extinguishing characteristics of C4F7N gas mixture were reviewed. Finally, the electrical, thermal decomposition mechanism and characteristics of C4F7N gas mixture were discussed. The future research trend of insulation as well as the electrical, thermal decomposition properties were promoted.
