一种提高CVT绝缘介质损耗及电容量测量准确度的有效方法

Improving Measurement Accuracy of Insulation Dielectric Loss and Capacitance of CVT

文章针对江西新余发电有限责任公司CVT的特殊结构,采用具有CVT功能的测量仪器,并结合一系列的现场反干扰措施,测试准确度大大提高,取得了良好的测试效果,能够反映CVT的真实绝缘状态。

According to the lower measurement accuracy of insulation dielectric loss and capacitance of CVT adopting the self- excitation method on site with QS1 electric bridge usually, this paper presents the measurement instrument with CVT function aimed at the special structure of CVT in Jiangxi Xinyu Power Generation Company. This measurement instrument has gotten good test effect combined with a series of and - disturbance measures on site, and test accuracy of the instrument rises gready, which can reflect the real insulation condition of CVT.
