Arcing Device of a Prefabricated Jumper for Insulator Strings Protection in Transmission Tower

摘要

In the assembled jumper device 14 of the transmission line, an arcing device for inducing discharge during flashover by making a flashover path for protecting the insulator 13, the ground side arcing ring 110 and the above-mentioned. The wire-side arcing ring mounted on the horizontal bracket 14a of the prefabricated jumper device 14 and the fixing bracket 120 for attaching the ground-side arcing ring 110 to the pylon arm 12 or the pylon auxiliary arm 12 '. It is characterized in that the jumper horn 100 is configured by installing 150. The ground-side arcing ring 110 is composed of an arcing ring 111 and the support 113, the arcing ring 111 is formed of a U-shaped tube, both ends of the U-shaped tube ( At least two fixing holes 111b are formed in the 111a, and the support 113 has a fastening hole 113a corresponding to the fastening holes 121a and 121b of the fixing bracket 120 at the top thereof. In the lower portion is formed by forming a plurality of fixing holes (113b) at a predetermined interval, the fixing bracket 120 is the same radius around the upper fastening hole (121a) and the upper fastening hole, a predetermined angle interval The fastening plate 121 formed by forming the angle adjusting fastening hole 121b is integrally formed on both sides of the base member 123 mounted to the pylon arm 12, and the wire side arcing ring 150 is formed. The support tube 153 is integrally formed on both sides of the track-like tube 151 and the track-like tube 151 and has a predetermined height and a fastening hole 153a is formed at an end thereof. It is characterized by consisting of.
