【摘要】:在總結分析容性設備在線監(jiān)測裝置現(xiàn)有校驗方法的基礎上,提出一種新型的全系統(tǒng)校驗方法,并開發(fā)相應的校驗系統(tǒng),實現(xiàn)容性設備在線監(jiān)測裝置離線條件下泄漏電流和介損值準確性的全量程校驗以及在線條件下實際運行點的校驗。通過量值溯源和現(xiàn)場驗證試驗,證明該校驗系統(tǒng)的介損測量絕對誤差0.1%,電容比率測量相對誤差2%,滿足校驗需求。
[Abstract]:On the basis of summing up and analyzing the existing calibration methods of capacitive equipment on-line monitoring device, a new type of full-system calibration method is proposed, and the corresponding calibration system is developed. The full range calibration of leakage current and dielectric loss accuracy under off-line condition of capacitive equipment on-line monitoring device and the verification of actual operation point under on-line condition are realized. It is proved that the absolute error of dielectric loss measurement and the relative error of capacitance ratio measurement are 0.1 and 2 respectively, which meet the needs of calibration.
