变压比电桥检定装置的研制

The Development of Verification Apparatus for Transformer ratio Bridge

变压比电桥检定装置是检定变压比电桥的专用检定装置。该装置主体部分为六位感应分压器，并在其输入、输出回路中增加了相序开关、连接组别、分接头、倍率转换等部件，使整个装置具有操作方便、能直接读取测量结果的特点。该装置设计合理、技术先进，并有可靠的计量溯源。

Abstract A transformer ratio bridge verification apparatus is introduced in this paper. The main part of the apparatus is a six decimal IVD, in which the phase exchange switch, link constitution, branch head and multiple switch have been added to the input and output circuits. It is very simple to operate the instrument with the feature of direct readings. This apparatus is rationally designed and technically advanced with reliable metrology traceability.
