Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the anti-around-striking lightning arrester, and particularly relates to a high-voltage line anti-around-striking lightning arrester. BACKGROUND

[0002] Around-striking refers to the phenomenon that lightning bypasses a lightning conductor and directly strikes a conductor, and the anti-around-striking lightning arrester is installed on the conductor of the high-voltage line; when lightning around-strikes the conductor, the lightning arrester can act first, and by virtue of its nonlinear resistance characteristic, the lightning arrester presents a low-resistance state under the action of lightning overvoltage, thereby leading the lightning current into the ground, so as to limit the overvoltage amplitude acting on the conductor and avoid the insulation of the conductor being broken down by lightning overvoltage, thereby playing a role in protecting the normal operation of the line.

[0003] The existing high-voltage line anti-around-striking lightning arrester is usually installed below the high-voltage line to prevent lightning around-striking, and is connected in turn using the line, so as to protect the line evenly.
