Abstract

The invention discloses a hardware tool for installing an arrester on an overhead power transmission line. The hardware tool comprises an upper part and a lower part, wherein one end of the upper part of the hardware tool is connected with a ball clevis on the top of a line insulator, and the other end of the upper part is connected with one end of an arrester body; one end of the lower part of the hardware tool is connected with a socket clevis at the bottom of the line insulator, and the other end of the lower part is a free end; an air clearance is formed between the free end of the lower part and the free end of the arrester body; and the angle of the upper part and / or the length of the lower part can be adjusted. The hardware tool has the advantages that the installation process is greatly simplified, the generality of the hardware tool is high, individual design for various tower types is not required, and field working load is greatly reduced.

Description

technical field [0001] The invention relates to electric power technology, in particular to fittings for installing lightning arresters on overhead power transmission lines. Background technique [0002] The overhead transmission line is a transmission line that uses insulator strings to fix the transmission wires on the towers standing on the ground to transmit electric energy. [0003] Lightning arresters are installed on overhead transmission lines as lightning protection devices. Commonly used lightning rods and lightning conductors (that is, overhead ground wires) release lightning charges to the ground through low-resistance conductors to protect the lines. In addition to preventing lightning from directly hitting the wires, the lightning conductor also has a shunting effect. However, in some mountainous and hilly areas, even if a negative protection angle is adopted, it cannot effectively prevent direct lightning strikes. [0004] With the application of the compos...
