Description

This invention relates to insulating rods for applying protective grounding. In the known construction of insulating rods, the clamps for connecting to a wire or bus (rod head) are fixed to the rod. Therefore, in the process of working with rods of this kind, when grounding is applied to wires or tires of different spatial locations, difficulties arise in connection with the necessity of locating the rod by an angle to the vertical, which obstructs maneuverability and maneuverability of its personnel. In addition, since the oltanga, due to its own weight, tends to always be in a vertical position, when its node is angled to the grounding bus or wire, an additional torque is created on the deformation of the specified wire or tire, which tends to break the contact between the boom clamp and the ground subject matter.

The considered invention is devoid of this drawback, since, in order to impose a protective grounding on the wires and tires of any spatial arrangement, the connecting clip of the rod, due to the use of a hinge in combination with a spring, is made pivoting.

; FIG. 1 shows the insulation rod, general view; Fig-2 - a section along the connecting clip; in fig. 3 - options for grounding the wire under consideration; in fig. 4 - tire grounding options.

Each rod (Fig. 1) consists of a working / and insulating 2 parts. The protective grounding kit includes three rods connected by a flexible copper wire 5, having a clamp 4 at the end, i.e. a clamp connected to the ground terminal. The working part consists of a connecting clip (fig-2), consisting of a head 5, put on the wire or bus to be earthed, a movable bar 6. of a mounted spring 7, a screw 8, a hinge 9 and a bar Yu bolted by // bolts insulating part 2 rod. The flexible wire 3 is connected to the head 5 by means of a strip 12 and bolts 13.

As an example of the use of the rod in FIG. Figures 3 and 4 show various options for mounting the rod depending on the spatial arrangement of the objects to be grounded. FIG. 3 shows the grounding of the wires for their horizontal and inclined arrangement, and FIG. 4 - grounding tires at their location on the edge or plane (flat).

Subject invention

A rod for imposing a protective earthing, the head of which is made in the form of a screw clamp that is worn on a wire or bus, characterized in that, in order to enable the imposition of grounding at any spatial arrangement of the wire or bus, said head is connected to the holder by means of a hinge spanning the mounting a spring.
