Zinc oxide arrester has excellent protection characteristics

The zinc oxide surge arrester is an electrical product used to protect various electrical equipment in the power system from over voltage damage and has good protection performance. Because the non-linear volt-ampere characteristics of the zinc oxide valve plate are excellent, only a few hundred microamps of current is passed through the normal operating voltage, which is convenient to design a gapless structure, which has good protection performance, light weight and small size. feature. When the over voltage invades, the current flowing through the valve plate increases rapidly, and the amplitude of the over voltage is limited, and the energy of the over voltage is released. Thereafter, the zinc oxide valve plate returns to a high resistance state, so that the power system works normally.
