摘要
根据人工气候室内变压器套管介质损耗因数(tanδ)的在线测量结果,分析了环境因素对电容型设备的tanδ的影响,提出并建立了主要环境因素对tanδ影响的灰关联分析模型,计算得出了主要环境因素对tanδ影响的关联度。结果表明,在没有屏蔽环的情况下,温度、湿度和绝缘表面污秽程度对电容型设备的tanδ均有影响;在有屏蔽环的情况下,温度对电容型设备的tanδ的影响明显大于环境湿度和绝缘表面污秽度对其的影响。
Based on the test results of dielectric loss factor(tanδ) of transformer bushings in an artificial climate chamber,the effect of environment factors on the tanδ of capacitive equipment was analyzed;and a grey correlation analysis model was established for representing the effect of environment factors on the tanδ.The influence of temperature,humidity and contamination on the tanδ is evident when there is no shielding ring.When the shielding ring is applied, the influence of temperature is larger than that b...
