Gases for electrical insulation are essential for the operation of electric power equipment. This Review gives a brief history of gaseous insulation that involved the emergence of the most potent industrial greenhouse gas known today, namely sulfur hexafluoride. SF₆ paved the way to space-saving equipment for the transmission and distribution of electrical energy. Its ever-rising usage in the electrical grid also played a decisive role in the continuous increase of atmospheric SF₆ abundance over the last decades. This Review broadly covers the environmental concerns related to SF₆ emissions and assesses the latest generation of eco-friendly replacement gases. They offer great potential for reducing greenhouse gas emissions from electrical equipment but at the same time involve technical trade-offs. The rumors of one or the other being superior seem premature, in particular because of the lack of dielectric, environmental, and chemical information for these relatively novel compounds and their dissociation products during operation.

评估用于电气绝缘以替代最有力的工业温室气体SF ₆的环保型气体

用于电气绝缘的气体对于电力设备的运行至关重要。这篇综述简要介绍了气体绝缘的历史，其中涉及当今已知的最有效的工业温室气体六氟化硫的出现。SF ₆为节省空间的设备用于电能的传输和分配铺平了道路。在过去的几十年中，其在电网中不断增加的使用对大气中SF ₆含量的持续增加也起了决定性作用。该评论广泛涵盖了与SF ₆有关的环境问题排放并评估最新一代的环保替代气体。它们具有减少电气设备温室气体排放的巨大潜力，但同时涉及技术折衷。一种或另一种是优等的传言似乎为时过早，特别是由于这些相对新颖的化合物及其在操作过程中的解离产物缺乏介电，环境和化学信息。
