Universal power signal based on the power system protection plate modular design

Based on power system protective plate common signal charge modular design, technical field signal belongs to an excess electric power system protection circuit in a power conversion control system voltage and current. Jumper means includes a signal input, core protection module unit, a signal isolation means, a signal output patch section, the bottom plate; patch signals input unit, a signal isolation means, a signal output patch design directly on the base unit, the core protection module It is connected to the bottom plate through the receptacle. Jumper input signal through the signal input unit, the collected signals to monitor core protection module unit, through the logic processing of the signals, the core unit through the protection module jumper signal output unit, the isolation unit fault signal via a signal isolation and filtered output. Advantage is that by the core circuit design and configuration, to maximize the protection circuit to achieve a good versatility, selectivity and flexibility.
