Lightning arrester against winding shock and mounting tool

Abstract

The invention discloses an anti-shielding failure lightning rod without threading installation and an installation tool thereof. The lightning rod comprises a lightning rod bar, a wiring clip, a balancing device and a needle bar hanger, wherein, the wiring clip comprises a pressure pad and a lower cover; one end of the lightning rod bar is connected with the needle bar hanger; the needle bar hanger is connected with the lower cover; the pressure pad is in movably connected with one end of the lower cover; a damping ring is fixed on the needle bar hanger. The lightning rod also comprises a spring self-locking device to be connected with the wiring clip; and the spring self-locking device is used for fastening the wiring clip on a ground wire. In order to install the lightning rod without threading, the installation tool of the anti-shielding failure lightning rod comprises a hanging plate with a through hole at the lower end and a trolley arranged on the hanging plate; a positioning device and a fixing device are arranged under the trolley in sequence, wherein, the positioning device is used for positioning the anti-shielding failure lightning rod at the required position, and withdrawing the installation tool after the installation is completed; and the fixing device is used for fixing the anti-shielding failure lightning rod on the ground wire.

Description

technical field [0001] The invention relates to a protective fitting for preventing lightning shielding wire failures of overhead transmission lines, in particular to an anti-shielding lightning rod that does not need to be installed on-line, and also relates to an installation tool for the shielding-proof lightning rod. Background technique [0002] High-voltage transmission lines, especially ultra-high-voltage transmission lines, have a high failure rate of lightning shielding conductors, so it is necessary to install anti-shielding lightning rods. For ordinary lightning rods, the installation method is generally to be installed by the operator on the line. Not only the personal safety of the installers has great hidden dangers, but the ground wire is also easy to cause external damage. At the same time, the power department needs to apply for a power outage because of the installation of the anti-shielding lightning rod. People's production and life are affected. At pres...

Problems solved by technology

For ordinary lightning rods, the installation method is generally to be installed by the operator on the line. Not only the personal safety of the installers has great hidden dangers, but the ground wire is also easy to cause external damage. At the same time, the power department needs to apply for a power outage because of the installation of the anti-shielding lightning rod. Impact on people's production and life

At present, there is no lightning rod and installation tool on the market that can be installed without the need for operators to solve the problem of on-line installation of lightning rods
