Description

Technical Field

[0001] The utility model belongs to the technical field of lightning arresters, and in particular relates to a lightning arrester protection device. Background Art

[0002] Lightning arresters are sometimes also called overvoltage protectors and overvoltage limiters. They are used to protect electrical equipment from high transient overvoltage hazards and limit the follow-on time and often the follow-on amplitude. They are usually connected between the grid conductor and the ground wire, and sometimes also connected next to the electrical winding or between the conductors.

[0003] At present, the majority of lightning arresters are installed directly on the tower through bolts. Since the lightning arrester has a certain wind-exposed area, the installation method of direct bolt connection will cause the installation stability of the lightning arrester connection position to gradually decrease under the action of wind force over a long period of time, thus posing a certain degree of safety hazard.

[0004] In view of this, the present utility model is proposed. Utility Model Content
