摘　　要：变压器油中溶解气体在线监测是对油浸式变压器绝缘状况进行实时监测的有效技术手段。对油中溶解气体在线监测装置进行运行质量评价,对装置选型、供应商评价和保障变压器运行可靠性具有重要意义。现有的变电在线监测装置运行质量评价研究存在数据规模小和评价指标有限等问题。为提高评价水平,文中统计分析了大型数据集中在线监测装置的厂家分布、运行年限分布、数据质量等重要信息,然后建立了油中溶解气体在线监测装置运行质量的模糊层次综合评价模型;最后对数据集进行评价结果分析统计,证明了该评价体系反映各厂家监测装置实际应用情况的准确性。On-line monitoring of gases dissolved in transformer oil is an effective technical means for real-time monitoring of the insulation status of oil-immersed transformers.The operation quality evaluation of on-line monitoring devices for gases dissolved in oil is of great significance for device selection,supplier evaluation and reliability of transformer operation.The quality evaluation of existing one monitoring device of transformer has such problems as small data scale and limited evaluation index.For improving the evaluation level,in this paper,such important informtion as distribution of manufacturers,operating years and data quality of large date center on-line monitoring devices are statically analyzed,then the fuzzy hierarchical comprehensive evaluation model for the operating quality of online monitoring devices of gases dissolved in oil is set up.Finally,it is proved by the analytic statics of the evaluation result that the evaluation system reflects the accuracy of actual application of the monitoring devices of various manufacturers.
