Abstract

The invention discloses a lightning protection insulator for 10KV tension rods. The lightning protection insulator comprises an insulator body, an arc striking ring and a discharge ring. One end of the insulator body is connected with the arc striking ring, and the other end of the insulator body is connected with the discharge ring. The lightning protection insulator is low in cost, convenient and flexible to construct and high in mechanical performance and has lightning protection function.

Description

technical field [0001] The invention relates to an insulator, in particular to a 10KV tension rod lightning protection insulator. Background technique [0002] With the popularization of insulation work in overhead distribution network, there are many researches on the measures to prevent lightning strike and disconnection of insulated wires, but at present, the lightning protection measures of foreign insulated distribution lines are mainly applied to straight rod insulators, and there is no lightning protection for tension insulators. measure. It is generally believed that the lightning current at the tension rod can be released through the lightning protection measures of the straight rod. This concept has also become the current situation that there is no lightning protection measure for the tension rod of the 10kV overhead distribution line in China. However, in recent years, the phenomenon of lightning strike and disconnection of insulated conductors at tension rods h...
