The invention discloses an arc generating device and an electric contact material anti-arc ablation performance evaluation method. The arc generating device comprises a control module, a power supplymodule, an arc discharge anode, an electric console and a data acquisition module, wherein the anode of the power supply module is connected with the arc discharge anode, and the cathode is connectedwith a sample of an electric contact arranged on the electric control table, so as to provide an arc discharge voltage. The electric console is connected with the control module for approaching or removing the arc discharge anode according to the output signal of the control module. The data acquisition module is arranged between the cathode of the power supply module and the electric console, andis connected with the control module, so as to collect the discharge current in the arc discharge process and send the discharge current to the control module. When the distance between the electricconsole and the arc discharge anode is adjusted by the control module to meet the condition, an arc breakdown discharge can be carried out between the arc discharge anode and the sample of the electric contact in the arc generating apparatus.
