Gap control apparatus of gap type arrester for transmission line

摘要

The present invention relates to a gap adjusting device of the gap-type lightning arrester for power transmission line, the counterweights (32, 32) fixed to one end of each of the arrester mounting base (31, 31); A terminal (33, 33) from below of the arrester (30, 30) fixed to the other end of each of the arrester mounts (31, 31) with a bolt nut; An arrester body (34, 34) fixed to the terminal (33, 33) from below; A terminal (35, 35) from above the "a" shaped plate shape fixed to the upper live lead of the arrester main body (34, 34); The gap horns 36 and 36 are installed on the terminals 35 and 35 so as to be rotatable and adjustable in length, respectively. And the adjustment of the interval is easy, and it is possible to save the time and manpower required by the worker in the high-altitude operation, and it is easy to adopt to various types of insulators such as suspension insulator and built-in insulator. In addition to this path, due to the characteristic difference of the zinc oxide elements stacked inside the arrester, lightning arresters with different specifications (total length) and fixing methods can be used for each manufacturer, and standardization of the arrester installation device on the grounding side and the charging side is excellent. It is a useful design with special advantages that can be used.;Transmission line, gap arrester, insulator, arc horn, gap horn.
