Description
Technical field
The utility model relates to electric transmission line isolator technical fields, and in particular to a kind of 35kV~110kV transmission line of electricity
Electric screw type earthing or grounding means.
Background technique
Since " installing connects regulation under the conditions of shaft tower or good cross-arm ground connection in national grid electric power safety working regulation
When ground wire, ground line can individually or merging is connected on shaft tower, but pole tower ground resistance or Grounding should be good, draw no ground
Temporary grounding body can be used in offline shaft tower, and the sectional area of temporary grounding body is inaccurate to be less than 190mm2, the depth of burying is not allowed to be less than
0.6 meter ", but since temporary earthing device does not have dimension mark, on-site personnel is usually to the temporary earthing device depth of burying
0.6m specified in regulation is not achieved, causes earthing effect bad, causes to operate against regulations.
Since transmission line operation place is mostly in mountain area field, shaft tower periphery geological conditions is different, encounter sandstone etc. compared with
In the case where hard soil property, temporary grounding body is manually difficult to be inserted into the earth.
Summary of the invention
The utility model provides a kind of 35kV~110kV transmission line of electricity electric screw type ground connection in view of the deficiencies of the prior art
Device, it is characterised in that: it is provided on motor housing (2) handle (1), the side of motor housing (2) is provided with motor switch (3),
It is provided with motor (12) in motor housing (2), motor (12) is connected with the input shaft of retarder (11), the output of retarder (11)
Axis is fixedly connected by insulated connecting rod (10) with grounding rod (5), the junction between insulated connecting rod (10) and grounding rod (5)
It is additionally provided with limitation valve (9), is provided with and connects wires interface (4) in limitation valve (9), grounding rod is additionally provided with screw thread on (5)
(7), scale (8), the bottom end of grounding rod (5) are provided with ground connection drill bit (6).
The diameter of the grounding rod (5) is 190mm.
The utility model has the beneficial effects that: a kind of feature that transmission line of electricity temporary earthing device is main is original
Scale has been done on temporary earthing device, and has installed a scale limitation valve additional at 0.1-0.9 rice, by limiting valve to scale
It adjusts, will be very clear to the buried depth on-site personnel of grounding body, on-site personnel can be effectively prevented and face embedded
When earthing or grounding means when the phenomenon of depth of burying deficiency led to due to the error in judgement to size, prevent such generation violating the regulations.
The tool limits the connection insulating materials of tolerable 35kV-110kV voltage between valve and motor in scale, prevents
Only the tool is damaged by external voltage.
The tool, using the spiral of similar electric drill, can be driven light in metallic ground body portion by motor above
Pine pierces in the more hard geology such as sandstone, largely saves manpower.
Detailed description of the invention:
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the electric appliance connection figure of Fig. 1；
