变压器油中气体在线监测装置检定技术发展研究

摘要

In allusion to the conditions that the online monitoring device faults of gas in the transformer oil frequently occurred, starting from oil-gas separation unit, gas composition separation unit etc five performance units of online monitoring device of gas in transformer oil, this paper compared and analyzed the application characteristics and limitations of commonly-used chromatographic data comparison method, standard gas comparison method, traditional tank of oil distribution comparison method and verification instrument direct calibration method etc four kinds of calibration technologies in traditional laboratory at present, and put forward the corresponding reasonable and fea-sible improvement recommendations and development aspirations.%针对变压器油中气体在线监测装置故障频发的情况，从油中气体在线监测装置的油气分离单元、气体组分分离单元等五大性能单元入手，比较分析了目前常用的传统实验室色谱数据比对法、标准气体比对法、传统油箱配油比对法、检定仪直接校验法等四种检定技术的应用特点和局限性，并提出了相应合理可行的改进建议及发展期望。
