Electrical safety detects protection circuit, switchgear and socket

The utility model provides an electrical safety detects protection circuit, switchgear and socket, circuit connection is on the power supply line with the electric loading in the protection, includes: current sensor gathers current signal on the power supply line, voltage sensor gathers voltage signal on the power supply line, the residual current sensor is gathered residual current signal on the power supply line, processing circuit receives current signal, voltage signal and residual current signal carry out the preliminary treatment, the controller with processing circuit connects, judges after the preliminary treatment whether current signal, voltage signal and residual current signal surpass the threshold value that corresponds, if then control is sent the alarm and/or is cut off and supply power with the electric loading. This protection circuit utilization detects the sensor, constitutes an electric monitored control system, and in the convenience of guaranteeing intelligent house ...
