摘要

鉴于产品碳足迹（CFP）正成为新的产品评价维度，文中以两家公司公开的6种12kV开关柜CFP为基础，比较分析具有代表性的空气绝缘、SF

气体绝缘和环保气体

绝缘三种绝缘方式，在不同系统边界和阶段的碳足迹，表明CFP主要集中在原材料获取和产品使用阶段共约占80%-92.5%，并受产品结构、绝缘方式及气体介质影响，其中SF

和环保气体绝缘开关柜CFP仅为空气绝缘开关柜的31%-35%，环保气体开关柜比SF

气体绝缘开关柜低8%-12.5%；通过这两主要阶段碳足迹和主要构成材料的简化比较分析，指出产品设计基本决定原材料获取和产品使用阶段碳足迹，也基本决定CFP，因此产品设计需要平衡和优化好这两个主要阶段才能降低CFP，并指出国内产品的材料使用效率仍需提高，并进一步指出要通过CFP更好实现产品的比较、评价和选择，建议建立符合GB/T24067附录B要求的相对统一的比较评价模型。

Abstract

Given that product carbon footprint(CFP)is becoming a new dimension for product evaluation

this article compares and analyzes the CFP of six publicly available 12kV switchgears from two companies

at different boundaries and stages for three representative insulation methods

namely air-insulated

SF6-insulated

and environmentally-friendly gas-insulated

the comparison shows that CFP is mainly concentrated in the stages of raw material acquisition and product use approximately 80%-92.5%in total

and is influenced by product structure

insulation method and gas dielectric

among them the environmentally-friendly gas-insulated and SF6-insulated are 31%-35%of than air-insulated

while environmentally-friendly gas-insulated is lower than SF6-insulated 8%-12.5%; a simplified method is used by the comparison and analysis of the two main stages and constituted material of the product

and points out that the CFP during the raw material acquisition and product use stage are basically determined by the product design

and also the CFP of the product

therefore the product design needs to balance and optimize these two main stages in order to reduce the CFP; and also pointed out that the material efficiency of domestic products still needs to be improved

furthermore it is necessary to better compare

evaluate and select products through CFP

which requires the establishment of a relatively unified CFP evaluation model which complied with appendix B of GB/T24067.
