一体式变压器综合试验仪的量值溯源

Reading Traceability of Integrated Transformer Comprehensive Tester

变压器常规测试项目有变压器变比测试、直流电阻测试、短路阻抗测试、有载分接开关测试、空负载测试、介质损耗测试等。随着科技的发展,集成化水平的提高,变压器的测试仪器也由单个项目分别使用专用仪器测试,逐步发展为一体式仪器集中测试。从实际需求出发,针对一体式变压器综合测试仪的主要测试项目,从电磁计量专业领域进行分析,解决此类一体化仪器的量值溯源问题。

Conventional testing itemsfor transformers include transformer ratio testing,DC resistance testing,short-circuit impedance testing,on-load tap changer testing,no-load testing,dielectric loss testing,etc.With the development of technology and the improvement of integration level,the testing instruments for transformers have gradually developed from a single itemto a stage of centralized testing with integrated instruments.Starting from practical needs,this article analyzes the main testing items of integrated transformer comprehensive tester from the professional field of electromagnetic metrology,and solves the problem of reading traceability of such integrated instrument.
