Research on Calibration Method and Uncertainty Evaluation of DC High Current Comprehensive Test Device
摘要
Abstract
DC high current comprehensive characteristic test device is used to detect the released characteristics of DC low-voltage electrical overcurrent protection electrical device,which is used in low-voltage electrical industry for DC products for long time delay,short time delay,instantaneous tripping test and short circuit test.With the wide application of DC low-voltage electrical products in non-ferrous metallurgy,chlor-alkali chemical industry,low-voltage power distribution,DC transmission and distribution,new energy and railway applications,the DC high current comprehensive characteristic test device used for DC electrical product testing needs to be traced regularly to ensure that it can meet the accuracy requirements of the test detection capability.In the field of measurement calibration,the present situation of relevant calibration methods was analyzed,and the research direction of calibration methods of this test device was reviewed.According to the corresponding product of the test device and the national standard,a new calibration parameter was proposed.Aiming at the calibration problem of the DC high-current device,the measurement method of optical fiber current sensor was proposed,so as to evaluate the uncertainty of the data generated.关键词
