Embodiment Construction
[0024] The content of the present invention will be further described in detail below in conjunction with each accompanying drawing.
[0025] refer to figure 1 , figure 2 and Figure 4 As shown, a universal bracket 70 for installing a lightning arrester 80 on a high-voltage transmission line tower. The base is connected to ensure that the arrester 80 is plumb to the ground. The universal bracket 70 includes a door-shaped plate 10, a U-shaped bolt 20, an L-shaped hanging plate 30 and a base plate 40. The door-shaped plate 10 is close to the outer surface of the overhead ground wire cross arm 50 of the iron tower, and crosses the iron tower through the U-shaped bolt 20. After the overhead ground wire cross arm 50, the door-shaped plate 10 is removably fixed on the cross-arm 50, and the back side of the vertical section 31 of the L-shaped hanging plate frame 30 is close to the door-shaped plate 10 and detachable from it. The upper part of the door-shaped plate 10 is provi...

A universal support (70) for mounting a controllable discharge lightning arrester on a high-voltage transmission line iron tower comprises a door-shaped plate (10), U-shaped bolts (20), an L-shaped hanger plate (30) and a pedestal plate (40), wherein the door-shaped plate (10) is detachably firmly connected with a cross arm (50) through the U-shaped bolts (20); the vertical segment (31) of the L-shaped hanger plate (30) is detachably firmly connected with the door-shaped plate (10); the door-shaped plate (10) is provided with a round through hole (110) disposed in the upper part and is provided with an arc-shaped through hole (111) disposed in the lower part; the L-shaped hanger plate (30) rotates along the arc-shaped through hole (111), taking the round through hole as the center of a circle; the horizontal segment of the L-shaped hanger plate (30) is fixedly connected with the pedestal plate (40); and the lightning arrester (80) is detachably fixed on the pedestal plate (40). The support can be adapted to various types of towers, is simple and firm, and is convenient to use and low in cost.
Description
technical field [0001] The invention relates to equipment used in high-voltage transmission lines, in particular to a universal support for installing controllable discharge lightning arresters on iron towers of high-voltage transmission lines. Background technique [0002] High-voltage power lines in the wild environment are vulnerable to lightning strikes in bad weather. Therefore, it is very important to install a controllable discharge arrester on a high-voltage transmission line tower. The controllable discharge arrester has a base bracket, and its top is Lightning arrester composed of main pin, dynamic ring and energy storage element. The base support is a circular steel pipe with a square plate-shaped connecting seat, including a circular steel pipe with a diameter of 89mm and a height of 2000mm, or a circular steel pipe with a diameter of 116mm and a height of 3000mm. According to the design requirements, the controllable discharge arrester must be installed on t...
