摘要

摘要: 变压器是变配电站的核心设备，其运行状况显著影响电网的安全与稳定. 绝缘油是变压器中重要的工作介质，其在变压器运行中起到绝缘、散热等作用. 矿物绝缘油是当前广泛使用的变压器绝缘油种类. 绝缘油组分特性对变压器的工作性能影响很大. 随着运行时间延长，绝缘油易出现氧化、老化，导致绝缘可靠性降低. 准确分析绝缘油组分、早期发现绝缘油氧化、老化状况，对提高变压器运行安全水平有重要意义. 质谱分析法在绝缘油组分特性分析、氧化产物及老化指示物分析中，展示了良好的应用潜力. 综述了近年来质谱分析技术在绝缘油性能品质检测，氧化、老化产物检测及过程机理分析等方面的研究进展，提出了未来进一步提高绝缘油特性及故障分析准确度的建议.

Abstract: The transformer is the key equipment of the power transformation and distribution station, and its operation status significantly affects the security and stability of the power grid. Insulating oil is an important working medium in the transformer, which plays an important role in insulation and heat dissipation during the transformer operation. Mineral insulating oil is the current widely used type of transformer insulating oil. The component characteristics of insulating oil have a significant impact on the working performance of the transformer. With the extension of operation time, the insulating oil is prone to oxidation and aging, resulting in the reduction of insulation reliability. Accurate analysis of the components of insulating oil and early detection of oxidation aging of insulating oil are of great significance to improve the operation safety level of the transformer. Mass spectrometry has shown good application potential in the analysis of insulating oil components, oxidation products and aging indicators. The research progress of mass spectrometry technology in insulating oil performance and quality detection, oxidation and aging product detection and process mechanism analysis in recent years are reviewed, and suggestions for further improving the accuracy of the performance and fault analysis of insulating oil in the future are put forward.
