Metal oxide arrester is the most advanced over-voltage protector. By nuclear Heart devices using zinc oxide varistor, as compared with traditional silicon carbide surge arresters, surge arrester changed The volt-ampere characteristics, improved over-voltage Fow capacity, thus causing a fundamental change in arrester characteristics.
When the arrester in the normal working voltage, the current flowing through the arrester only microampere level, When subjected to over voltage, due to the nonlinear ZnO varistor, the current flowing through the arrester Instant thousands of amps, lightning arrester in the conduction state, the release of over-voltage energy, thusEffective to limit the over-voltage on the transmission and distribution equipment infringement.
