摘要
Abstract
A higher accuracy and automatic transformer's turn ratio group tester verification equipment has been introduced. It can solve the problems of little number variable ratio, the accuracy can not reach the requirements in turn ratio detection, complex operation and the low work efficiency. In this equipment, a dual core structure internal voltage transformer is applied, the precision of measurement has achieved 0.01%, which is the leading level of similar products; the instrument can provide 1 to 10000 variable ratios in verification , meeting JJG970-2002 Verification Regulation of Transformers Turn Ratio Test Sets; the control part use C8051F023 and CPLD as platform, a kind of popular touch screen design is also used in display, and the electrical circuit uses relays for automatic switch over, which improves the efficiency of detection greatly.关键词
