LIGHTNING ARRESTER

摘要

[PROBLEMS] To provide a lightning arrester exhibiting good response to overvoltage with no concentration of energy on one point at the time of discharge. [MEANS FOR SOLVING PROBLEMS] The lightning arrester comprises an energy absorber (3) for absorbing the energy of a thunderbolt and a pair of conductive electrodes (1, 2). Two air gaps (9) are formed in series between the pair of conductive electrodes (1, 2), one between the conductive electrode (1) and the energy absorber (3) and the other between the conductive electrode (2) and the energy absorber (3). Each of the two air gaps (9) includes a planar air gap.
