摘　　要：根据对目前电力系统大容量主变压器运行主保护瓦斯保护技术现状的分析,基于油流体多普勒效应原理,提出了一种全新精确流速光电测量原理的瓦斯保护装置,与电力系统其他保护发展同步,同时兼顾状态检修的稳定性,既保证了瓦斯保护的准确性与可靠性,也为新的智能站的匹配提供了新的思路,如果技术成熟,成本会大幅降低,为现有瓦斯保护提供可替代的新方案。According to the anhlysis on the present gas protection technology status of the main protection of operation of large-capacity transformer in power system, based on oil-bearing fluid Doppler effect principle, this paper proposes a new gas protection device based on accurate flow velocity photoelectronic measurement principle, synchronized with other protection development in power system as well as taking into account the stability of state maintenance, which not only can ensure the accuracy and reliability of gas protection, but also provide a new way of thinking for the new intelligent station matching. If the technology is mature, its costs will be greatly reduced and alternative new program for existing gas protection will be offered.
