Abstract
The utility model discloses a renewable energy converting system having function of electric leakage protection. The system includes a generator. A maximum power tracker and an inverter which are successively connected to the generator by a positive and negative cable; and an electric leakage protective unit is disposed between the generator and the maximum power tracker. In practical application, the solar energy or wind energy high-voltage direct current positive and negative cable passes through a current inductive coil of the electric leakage protective unit. When the solar energy or wind energy high-voltage direct current positive and negative cable is in electric leakage, the current inductive coil of the electric leakage protective unit detects a change signal of the current and converts and transmits the change signal to a microprocessor; the microprocessor sends a command to a switch on the solar energy or wind energy high-voltage direct current positive and negative cable for cutting off the cable when the electric leakage current reaches a rated electric leakage current value preset by the microprocessor, and switching on the cable when the cable is maintained. The renewable energy converting system having electric leakage protector is safer. The electric leakage can be found more easily and the electric leakage protective measure can be adopted.
