摘要： An arrester in the shape of a tank has a cylindrical grounding tank as an outer casing to be arranged vertically in which an insulating medium is enclosed. In the grounding tank, a non-linear element group is disposed, the non-linear element group is formed by vertically stacking a plurality of non-linear resisting elements in series at a substantially axially central portion of the grounding tank. A shield having an umbrella-like shape is disposed on a high potential side of the non-linear element group. A shielding unit is operatively connected to a low potential side of the umbrella-shaped shield through a support member. The shielding unit comprises at least one shielding member having a spherical shape provided with a spherical surface portion facing an inner side wall of the grounding tank. When two shielding members are disposed, they are positioned axially symmetrically with respect to the non-linear element group, which comprises a single column or a plurality of symmetrically arranged columns of non-linear resisting element stacks standing upwards along the central axis of the grounding tank.
