Description

Technical Field

[0001] The utility model relates to the technical field of overhead power distribution lines of electric power systems, in particular to a lightning protection piercing type post insulator. Background Art

[0002] A post insulator is a special insulating control component, which is mainly used to support power lines and maintain the distance between conductors and poles. It also plays the role of insulating power lines to protect the safety of workers and the public. The Chinese utility model patent, authorization announcement number "CN221327447U", discloses a post insulator that is easy to install, including a chassis and a post. The chassis outer wall has fixing holes at the front and rear ends and the middle of both sides of the upper end, and the chassis outer wall has multiple fixing grooves at both sides of the upper end. The outer wall of the post is fixedly sleeved with four umbrella skirts at the upper end. A steel cap is fixedly arranged at the center of the upper end surface of one of the four umbrella skirts near the upper end. A clamping mechanism is fixedly arranged at the center of the inner wall of the steel cap. The clamping mechanism includes an extrusion plate, four sliding bearings, two bolts, four locking claws, four support rods and two U-shaped grooves. A placement groove is arranged on both sides of the lower end surface of the outer wall of the post.

Moreover, since its lightning protection piercing post insulator has functions such as lightning protection, the composite shed in the post insulator is more prone to damage. When the composite shed in a post insulator is damaged, the entire post insulator cannot be used and the replacement cost after damage is too high. Utility Model Content
