Abstract
The utility model relates to a line-type zinc oxide lightning arrester used for 500KV transmission lines in high-altitude areas. Auxiliary cross arms (4) are symmetrically positioned at both ends of the extension frame of an iron tower (2). A zinc oxide lightning arrester (1) is suspended on the auxiliary cross arms in the transverse direction. The installation method of the line-type zinc oxide lightning arrester overcomes the problems of the prior suspension installation or sitting-type installation in the line travel direction and has the significant advantages of high safety and reliability and reasonable and scientific design.
Description
Technical field:
The utility model belongs to high height above sea level extra high voltage network, especially 500kV transmission line structure for installing lightning arrester technical field.
Technical background:
The line type zinc oxide arrester is installed, for the transmission line lightning protection provides a kind of novel and effective lightning protection means on the 500kV transmission line of high altitude localities.The mounting means of 500kV Transmission Line Arrestor has two kinds: hang and install and the sitting posture installation, be installed on the tangent tower more.At present, adopt along line direction suspension installation or sitting posture of the mounting means of 500kV Transmission Line Arrestor installed more, and also there is hidden danger in this mounting means because lightning arrester is placed oneself in the midst of along on the line direction on safety.
Summary of the invention:
The weak point that the utility model exists for the mounting means that overcomes above-mentioned existing 500kV Transmission Line Arrestor just and propose a kind of structure that the line type zinc oxide arrester is installed on the 500kV transmission line of high altitude localities.
The utility model adopts following technical scheme to realize.
Be provided with auxiliary cross-arm symmetry and be positioned at iron tower and stretch the frame two ends, zinc oxide arrester horizontal line road direction is suspended on the auxiliary cross-arm.
The invention has the beneficial effects as follows:
Adopt horizontal line road direction to be installed on that line steel tower is stretched the auxiliary cross-arm outside on the frame, the mode that the gap is tending towards level is installed high altitude localities 500kV Transmission Line Arrestor, for the installation of 500kV Transmission Line Arrestor provides a kind of new mode.The present invention successfully is applied to the sub-gap of tape insulation zinc oxide arrester on the 500kV transmission line of high altitude localities for the first time, and this mounting means is safe and reliable, scientific and reasonable, for applying of line type zinc oxide arrester accumulated the installation experience.
Description of drawings:
Fig. 1 is a straight line wineglass tower mounting means schematic diagram of the present invention;
Fig. 2 is a straight line cat head tower mounting means schematic diagram of the present invention.
Embodiment:
As Fig. 1, be provided with auxiliary cross-arm 4 symmetries and be positioned at straight line wineglass iron tower 2 and stretch the frame two ends, zinc oxide arrester 1 horizontal line road direction is suspended on the auxiliary cross-arm 4.Promptly just zinc oxide arrester 1 hangs on the direction outside, horizontal line road that is mounted on transmission line on the straight line wineglass iron tower 2.On auxiliary cross-arm 4 discharge counter 5 is installed, zinc oxide arrester 1 is provided with discharging gap 3, and the bottom of zinc oxide arrester 1 is connected with insulator 6 on hanging over auxiliary cross-arm 4; As Fig. 2, zinc oxide arrester 1 is hung on the direction outside, horizontal line road that is mounted on transmission line on the straight line cat head iron tower 2.The gap is tending towards the mounting means that level is installed, and promptly adopts horizontal line road direction to hang and installs.
