Abstract

The invention relates to an extension wire for a ground terminal. The extension wire comprises a standard ground wire, a ground wire ground terminal and an equipment ground terminal, wherein one end of the standard ground wire is connected to the ground wire ground terminal, and the other end of the standard ground wire is connected to the equipment ground terminal; the equipment ground terminal comprises a connecting main body and a firmware; the bottom of the connecting main body is connected with the standard ground wire; a circular hole is formed in the upper part of the connecting main body; the firmware is welded and mounted at the lower part of the side wall of the connecting main body; a through hole is formed in the center of the firmware; the axis of the through hole is vertical to that of the circular hole of the connecting main body; a mounting hole is formed in four corners of the firmware respectively; and the axes of the four mounting holes are respectively parallel to the axis of the circular hole of the connecting main body. By utilizing a single longer ground wire, one end of the ground wire is connected to the equipment ground terminal, and the other end of the ground wire is connected to a thread buckle on a ground wire ground side, namely the ground terminal can be extended without buying another longer ground wire, and an expected effect can be reached by utilizing the extension wire for the ground terminal, so that the cost is reduced, and the work is facilitated.

Description

Earth terminal extended line
Technical field
The present invention relates to the managing security tools and instruments in technical field of electric power, especially a kind of earth terminal extended line.
Background technology
Earth connection is exactly the line directly connecting the earth, also can be called safety return circuit line, and time dangerous, it just switches through high voltage direct and marries the earth, a lifeline at last.The firm installing of earth connection is the important leverage of work about electric power human life safety.But under the facility environment condition that some are special, earth terminal and conductor side can be connected the earth point of earth connection apart from long, cause normally to install earth connection.And in current managing security tools and instruments not a kind of instrument can effectively address this problem, so need a simple and effective solution.
Summary of the invention
The object of the invention is to the defect overcoming prior art, provide a kind of easy to use, the earth terminal extended line of work convenience can be improved.
The object of the invention is to be realized by following technological means:
A kind of earth terminal extended line, it is characterized in that: comprise standard ground line, ground connection end and equipment ground end, one end of standard ground line connects ground connection end, other end connection device earth terminal, this equipment ground end comprises and connects main body and firmware, the bottom of this connection main body is connected with standard ground line, a circular hole is made on the top of this connection main body, the lower weld of this connection main body wall installs firmware, a through hole is made at the center of this firmware, axis and the axis perpendicular being connected main body circular hole of this through hole, an installing hole is all made in the corner of this firmware, the axis of these four installing holes all with the axis being parallel being connected main body circular hole.
And described standard ground line is 10m.
Advantage of the present invention and good effect are:
Invention a kind ofly designs earth terminal extended line ingenious, rational in infrastructure, easy to use, the present invention utilizes a longer single earth connection, one end connection device earth terminal, the other end connects ground connection side screw buckle, so just can extend earth terminal.When earth connection falls short of, do not need to buy longer earth connection again, utilize earth terminal extended line just can reach desired effects, thus saved cost, facilitate work.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the vertical view of equipment ground end in Fig. 1;
Fig. 3 is the right view of equipment ground end in Fig. 1.
Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of earth terminal extended line, comprise standard ground line 2, ground connection end 1 and equipment ground end, standard ground line is 10m, and one end of this standard ground line connects ground connection end, other end connection device earth terminal.
Equipment ground end comprises and connects main body 3 and firmware 5, the bottom of this connection main body is connected with standard ground line, a circular hole 4 is made on the top of this connection main body, the lower weld of this connection main body wall installs firmware, a through hole 7 is made at the center of this firmware, axis and the axis perpendicular being connected main body circular hole of this through hole, an installing hole 6 is all made in the corner of this firmware, the axis of these four installing holes all with the axis being parallel being connected main body circular hole.
