Document Type and Number:
WIPO Patent Application WO/2014/169509
Kind Code:
A1
Abstract:
A power distribution network overvoltage protector equipped with a ring-shaped electrode and distanced grades, comprising: a bracket (1), wherein an insulator (2) and a lightning arrester (3) are respectively arranged on the bracket (1); a ring-shaped electrode (4) is sleeved outside of the insulator (2); and one end of the lightning arrester (3) is movably connected to an arc-shaped electrode (5). In the power distribution network overvoltage protector, the ring-shaped electrode (4) and the arc-shaped electrode (5) are used cooperatively, and distanced grades (51, 52 and 53) are arranged on the arc-shaped electrode (5), thereby significantly improving the lightning-protection performance of the voltage protector.
