摘要:
复合绝缘子因其强度高、韧性好,还具有良好的抗震性能及外绝缘性能,在国内多项超、特高压工程中得到了大量应用。充分调研了国内外关于复合材料电气设备的抗震研究现状,以800 kV新松换流站复合绝缘子为研究对象,分析了玻璃纤维增强树脂复合材料电气设备材料特性、法兰胶装型式及弯曲刚度等特性。进一步介绍了锤击法和环境激励法等电气设备动力特性现场测试方法测试原理和适用性,分别采用多点激励单点拾振法和多点激励多点拾振法对2只800 kV和1只400 kV复合绝缘子进行动力特性现场测试,采用模态参数识别方法得到了绝缘子前几阶自振频率、振型及阻尼比。此外,还初步探讨了在带电状态下如何实时监测和检测电气设备动力特性的测试方法。上述研究对今后开展复合电气设备抗震设计及评估具有很好的参考、借鉴作用。
Abstract:
Composite insulators have been widely used in many EHV and UHV projects in China because of their high strength, good tenacity, good seismic performance and excellent insulation performance. The research status of seismic performance of composite electrical equipment at home and abroad is fully investigated, taking 800 kV composite insulators of Xinsong converter station as the research object, the material characteristics, type of adhesive flange structure and bending stiffness of glass fiber reinforced plastics composite electrical equipment are analyzed.The principle and applicability of two test methods for dynamic characteristics of electrical equipment, hammering method and environmental excitation method, are introduced. Two 800 kV and one 400 kV composite insulators are tested by multiple input single outputmethod and multipleinput multiple output method respectively. The first several natural frequency, modes and damping ratios of insulators are obtained by themodal parameter identification method. In addition, the method of real-time monitoring and testing the dynamic characteristics of electrical equipment under charged state is preliminarily discussed. The above research has a good reference value for the seismic design and evaluation of composite electrical equipment in the future.
