Research on On-line Monitoring Technology of Pressure Drop in Secondary Circuit of Voltage Transformer and Directional Push Technology of Alarm Information

摘要

Traditional energy metering technology cannot monitor energy metering devices which number has been growing in real time and realize timely notification of alarm information, so it is difficult to effectively control the occurrence of metering accidents and reduce the amount of power. Through the analysis of the metering circuit, this article provides real-time monitoring the secondary circuits of voltage transformers which are the most error-prone. Ensure that the alarm information can be promptly notified when the voltage loss of the power meter and the secondary pressure drop are exceeded. And use a more stable operation board to reduce the occurrence of secondary circuit open-circuit faults. Finally, the practicality of the technology was verified through experiments.
