A large-capacity transformer primary current-rising protection device

Abstract

The present invention relates to a large-capacity transformer primary current-rising protection device, which aims to improve the adaptability of the transformer to complex power grid environments and operational safety. The device includes a monitoring module, an analysis and prediction module, an adaptive adjustment module, a fault isolation and recovery module, and a remote control and communication interface. The monitoring module real-timely monitors the current, voltage, temperature and load waveform of the primary side of the transformer through various sensors. The analysis and prediction module conducts in-depth analysis on the monitoring data, real-timely diagnoses the current state and predicts future trends. The adaptive adjustment module automatically adjusts the overcurrent protection threshold according to these analysis results. The fault isolation and recovery module isolates the fault area when a fault occurs, and determines whether to partially or fully restore power supply according to the fault impact. Finally, the remote control and communication interface ensures that the device can perform real-time communication with the central control system. The device improves the protection efficiency and accuracy of the transformer, and is suitable for complex and variable power grid environments.
