10KV line insulation lightning arrester and lightning shielding method

Abstract

The invention relates to the technical field of lightning shielding for power lines and discloses a 10KV line insulation lightning arrester and a lightning shielding method. In the method, a lightning rod 1 on a lightning arresting grading ring is used for receiving lightning, so that the lightning is instantly transmitted to a grounding wire on a line pole through an L-shaped insulation structure to prevent the lightning from striking off the line. The 10KV line insulation lightning arrester comprises the lightning rod, the lightning arresting grading ring, the L-shaped insulation structure and a grounding connecting clamp, wherein the vertical upper end of the L-shaped insulation structure is connected with the lightning arresting grading ring through a clamping ring; the upper end of the lightning arresting grading ring is fixedly connected with the lightning rod 1; and one end of the L-shaped insulation structure in the horizontal direction is connected with the grounding line on the line pole through the grounding connecting clamp. By the invention, a 10KV power transmission line can be prevented from being stroke by lightning and from being attacked by direct lightning or indirect lightning. The 10KV line insulation lightning arrester and the lightning shielding method are low in investment and maximized in profit; and high effective economic and social benefits are supplied to power departments for preventing disconnection and tripping of overhead lines caused by lightning strike.

Description

technical field [0001] The invention relates to the technical field of lightning protection for power lines, in particular to a 10KV line insulation lightning rod and a lightning protection method for high-voltage lines. Background technique [0002] At present, the main measures taken at home and abroad to prevent lightning breakage of 10KV overhead insulated conductors are: erecting overhead lightning conductors; installing zinc oxide arresters; installing metal hoops on column insulators, and installing arc-proof hardware on the load side. However, the existing technology has the following disadvantages: high investment cost, complicated construction and installation, and the need to peel off the insulation layer, resulting in water ingress and corrosion of the wire core, and the shed of the porcelain insulator is cracked due to arcing, which is affected by changes in the load side of the ring network power supply Wait.

However, the existing technology has the following disadvantages: high investment cost, complicated construction and installation, and the need to peel off the insulation layer, resulting in water ingress and corrosion of the wire core, and the shed of the porcelain insulator is cracked due to arcing, which is affected by changes in the load side of the ring network power supply Wait

[0003] With the transformation and insulation of electric power lines, the traditional design, due to the inherently insufficient lightning resistance level of insulated lines, is difficult to withstand the effects of direct lightning or induced lightning, and lightning strike disconnection has become another new problem faced by electric power
