Abstract:
Aiming at the potential problems that may be caused by the on-load capacity of isolation transformer, current loop relay, contact performance of wire pressing mechanism and so on, ordinary standard watt-hour meter, intelligent watt-hour meter and high-precision micro standard watt-hour meter compatible with the electrical characteristics, size and external structure of intelligent watt-hour meter(hereinafter referred to as mounted standard watt-hour meter) are used to detect the meter position in the automatic verification pipeline of intelligent watt-hour meter by different methods of no-load and on-load detection. By analyzing the detection data, the accuracy of meter position detection in automatic verification pipeline of intelligent watt-hour meter is studied, and an efficient and reliable detection scheme is proposed based on the research and analysis. Finally, the example verification shows that the on-load detection scheme of the automatic verification pipeline position of the intelligent watt-hour meter based on the mounted standard watt-hour meter significantly improves the detection accuracy, and the judgment of the meter position accuracy of the automatic verification pipeline position of the watt-hour meter is realized.
