摘要

六氟化硫(SF6)由于其优异的电绝缘和灭弧性能，在电力系统的各种设备中得到了广泛的应用。SF6也是最强的温室气体之一。由于设备的维护和退役，电气设备SF6气体泄漏和排放是不可避免的。以发展低碳电力系统为目标，对sf6的使用量和泄漏量进行估算。本文综述和分析了SF6气体泄漏到大气中的途径。在此基础上，提出了电气设备sf6排放量估算模型。以广东省电力系统实际数据为基础，以当量二氧化碳值与发电侧二氧化碳排放量进行比较。并根据广东省电力系统规划方案对未来SF6排放进行估算。所提出的方法有助于确定电力系统中不同部件对温室气体排放的贡献。讨论了对今后SF6管理工作的有益建议。

Estimating of sulfur hexafluoride gas emission from electric equipments

Sulfur hexafluoride (SF6) has been widely used in various kinds of equipments in the power system because of its outstanding capability of electric insulation and arc extinguishment. SF6 is also one of the strongest greenhouse gases. Due to equipment maintenance and retirement, SF6 gas leakage and emission from electric equipments is unavoidable. Aiming at developing a low carbon power system, SF6usage and leakage should be estimated. This paper reviews and analyzes the ways by which SF6 gas could leak into the atmosphere. On this basis, a model for estimating the amount of SF6emission by electric equipments is presented. Based on the practical data from Guangdong provincial power system, SF6 emission is compared at the value of equivalent carbon dioxide with generation side CO2 emission. Moreover, future SF6 emission is estimated based on Guangdong power system planning scheme. The proposed methodology is helpful to identify the contribution of Greenhouse Gas emission from diffident parts in power system. Useful suggestions for future work about SF6 management are discussed.
