Jumper device



【課題】 鳥が鉄塔にとまることで引き起こされる地絡を抑制できるジャンパ装置を提供する。 【解決手段】 一端が鉄塔10におけるアーム12の先端側につながり、他端が送電線側につながる一対の耐張碍子装置(耐張碍子連21)と、各耐張碍子連装置につながる送電線の端部同士を電気的に接続して吊下げられたジャンパ線22とを有するジャンパ装置である。この装置におけるジャンパ線22を、支持部材(支持ロッド23)を用いて鉄塔から離れる方向に張り出して支持する。支持部材は、一端が送電線側に連結され、途中で鉄塔から離れる方向に屈曲されて、他端側がジャンパ線22に沿って固定されるロッドが好適である。 【選択図】図1
<P>PROBLEM TO BE SOLVED: To provide a jumper device wherein the occurrence of ground fault caused by a bird perching on a steel tower can be suppressed. <P>SOLUTION: The jumper device comprises a pair of strain insulator sets (strain insulator strings) 21, one ends of which are coupled with the end of an arm 12 of a steel tower 10, and the other ends of which are coupled with a transmission line; and a jumper wire 22 that is suspended, electrically connecting together ends of transmission lines coupled with the individual strain insulator sets. Using a supporting member (support rod) 23, the jumper wire 22 is supported as is jutted out in the direction in which it goes away from the steel tower. For the supporting member, a rod is suitable one end of which is coupled with the transmission line and is bent at some midpoint in the direction in which it goes away from the steel tower, and the other end of which is fixed along the jumper wire 22. <P>COPYRIGHT: (C)2005,JPO&NCIPI
