変圧器の開閉インパルス試験のエキスパートシステム

Abstract

The power transformer used on UHV, EHV transmission line is put into switching impulse test after produced in the manufactory. This experiment is done in the impulse voltage generator (IVG). The experiment, according to the definited experimental voltage and the voltage wave's shape, needs the next conditions. One of the conditions is to determine the transformer, another to obtain its equivalent circuits constants, and then the construction of IVG and the charging voltage must be determined. Until now, this experiment has been the cut & try method based on the experience, for which the expert knowledge must be piled up and leads to more loss of the time required for IVG exchange time. The authors have tried the experiments of transformers for long. Recently we considered the algorism for the estimation of circuits constants in switching impulse test of transformer. From the results, the expert system for switching impulse test of transformer, adding the memories and educational functions, was developed by the arrangement of various expert knowledge.
