| description | The invention discloses a system and a method for evaluating the corrosion resistance of a direct-current insulator. Existing methods for simulating and evaluating actual operation conditions in an anti-corrosion capability test room of insulator hardware generally adopt fatigue strength, corrosion depth, leakage current and other empirical values, and the corrosion amounts of the fatigue strength, the corrosion depth, the leakage current and the like cannot be accurately and equivalently evaluated. The system comprises a direct-current power supply device, a charge current measuring device for collecting current flowing through an insulator fitting, a corresponding relation between the charge quantity and the fitting corrosion quantity is accurately measured and calculated according to the corresponding relation between the electron flow direction and anode metal ionization in electrochemical reaction, and the corrosion resistance of the direct-current insulator is evaluated according to the corresponding re |
