摘要

SF6气体是一种化学性质稳定的气体,具有优良的绝缘性能和灭弧特性,目前在高压电气设备GIS和GIL气室中具有广泛地应用,对提高电力系统输电容量和电力设备的小型化具有重要作用。但是SF6气体本身有局限性,是受管制的温室气体之一,能够有效替代SF6的新型环保绝缘气体在高压电气设备制造业中受到越来越多关注。新型绝缘气体密度继电器在新型绝缘气体高压电气设备中应用越来越广泛,为了保障密度继电器可靠运行,对新型绝缘气体密度继电器智能校验的研究与应用具有重要的意义。

Abstract

SF6 gas is a chemically stable substance known for its excellent arc-extinguishing performance and insulating properties. It is currently widely used in high-voltage electrical equipment such as Gas-Insulated Switchgear (GIS) and Gas-Insulated Lines (GIL) chambers, playing a crucial role in enhancing power transmission capacity and the miniaturization of electronic devices. However, SF6 gas has its limitations and is classified as a controlled greenhouse gas. Consequently, there is a growing focus within the high-voltage electrical equipment manufacturing industry on new environmentally friendly insulating gases that can effectively replace SF6. The adoption of these new insulating gases, particularly in high-voltage electrical equipment, is on the rise. To ensure the reliable operation of density relays, research and the application of intelligent calibration for density relay devices using novel insulating gases are of significant importance.

Key words: Gas density relay; Gas detection; Gas leak detection
