Abstract
The utility model discloses a high-voltage power transmission tower is with lightning protection device, include: lightning arrester, downlead and earthing device, lightning arrester is equipped with four lightning rods, and the lightning rod is connected on the lightning-arrest ball, is equipped with the bracing piece and connects lightning-arrest ball and support the base, downlead connection and lightning-arrest ball to lay alone and lead the underground down along the body of the tower main member from the top of the tower, earthing device and downlead connection are radially, the utility model discloses the tower body can not be electrified even when there is the thunderbolt yet to ground resistance is lower, and lightning protection effect is more ideal, has avoided producing huge instantaneous current impact when the transmission tower meets the thunder and lightning, has improved electrically conductive efficiency.
Description
Technical Field
The utility model belongs to the technical field of power supply unit, specifically be a dress is hit with lightning protection to high-voltage transmission tower.
Background
The existing lightning protection technology of the high-voltage transmission tower generally erects one or two lightning conductors at the top of the high-voltage transmission tower for lightning protection, but the high-voltage transmission tower is made of metal, so that a down lead is not adopted, and the metal tower replaces the down lead to conduct lightning. Patent publication No. CN 203631989U discloses a lightning arrester for high-voltage transmission tower, takes shelter from the thunder through the arrester, downlead and radial earthing device of arranging in the top of the tower in, plays the effect of taking shelter from the thunder, because only has a lightning rod, consequently, the effect of taking shelter from the thunder is not good enough, and is difficult for changing after impaired.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a dress is hit with lightning protection to high-voltage transmission tower to solve the not good problem of lightning protection effect that prior art exists.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a high voltage transmission is lightning protection device for tower, includes lightning arrester and earthing device, lightning arrester passes through downlead with earthing device and is connected.
Further, the lightning arrester comprises a supporting base, a supporting rod is arranged on the supporting base, a lightning protection ball is arranged at the upper end of the supporting rod, four lightning rods are arranged on the lightning protection ball, and the upper end of the down lead is connected with the lightning rods.
Furthermore, the grounding device is a radial structure consisting of a plurality of metal needles, and one end of the grounding device is welded and gathered at one point and connected to the lower end of the down conductor.
Furthermore, the lightning rod and the axis of the support rod form an included angle of 30-60 degrees, and the four lightning rods are arranged in pairwise symmetry.
Further, the supporting base is arranged on the top of the high-voltage transmission tower.
Furthermore, a plurality of stabilizing rods are arranged between the supporting rod and the supporting base and are uniformly distributed around the supporting rod.
Further, the metal needle is copper or silver or iron.
The utility model discloses following beneficial effect has:
the lightning arrester of the utility model is provided with four lightning arresters, the lightning arresters are symmetrically arranged in pairs, the arrangement angle is 30-60 degrees, the lightning protection area is increased, the lightning can accurately strike on the lightning arrester when the lightning occurs in the protection range, the phenomena of side strike and shielding strike of the traditional lightning arresters are avoided, and the lightning arrester is made of copper or silver or iron material, so that the lightning arrester has good electrical conductivity, low electrical resistivity and good thermal conductivity, and therefore has good lightning triggering effect; simultaneously, lay alone along the body of the tower from the top of the tower through the downlead and be connected with earthing device, the tower body also can not electrified even when there is the thunderbolt to ground resistance is lower, and lightning protection effect is more ideal, has avoided producing huge instantaneous current impact when power transmission tower meets the thunder and lightning, has improved electrically conductive efficiency.
