Abstract
The invention relates to a novel grounding probe of a groundmeter. The novel grounding probe comprises a handle, a loop and a probe, wherein the loop is welded at the top of the probe; a connecting transverse rod is welded at the upper end of the probe; two ends of the connecting transverse rod are respectively detachably connected with the handle. The novel grounding probe of the groundmeter, which is provided by the invention, has the characteristics of being convenient to dismount, easy to carry over and capable of helping groundmeter operators to conveniently and rapidly insert the grounding probe of the groundmeter into soil, so that the working intensity and the danger of the groundmeter operators can be degraded, and the working efficiency can be effectively improved.
Description
Technical field
The present invention relates to a kind of grounded probe, a kind of novel grounded resistance measuring instrument grounded probe.
Background technology
When newly-built built on stilts defeated, distribution line final acceptance of construction and built on stilts defeated, the distribution line of operation, will be to bar
Tower carries out grounding resistance measurement, and the mainly detection to line thunder protection equipment is tested, and prevents circuit because of earth resistance
Excessive and cause circuit suffer lightning wave counterattack voltage infringement, flashover tripping operation and have an accident.
When built on stilts defeated, distribution line shaft tower is carried out grounding resistance measurement, apply relatively broad in practice
Be ZC-8, ZC-29 type hand-rail type potentiometer-type ground resistance measuring instrument, such instrument is by ground connection
Megger, ground connection assist probes and steel wiring composition, measure time need by grounded probe copper wiring pull-out away from
Inserting underground after earthing megohm meter a certain distance, when measuring in the past, tester can run into so
One difficult problem, that is, the most especially can be very at the local insertion grounded probe that the soil properties such as mountain region are harder
Difficulty, it is native interior suitable that grounded probe is often inserted by tester by modes such as iron hammer, stone and pedals
The degree of depth, wastes time and energy, and has certain danger.
Summary of the invention
The problem that the present invention is directed to exist during above-mentioned existing defeated, distribution line shaft tower earth resistance, it is provided that
A kind of novel grounded resistance measuring instrument grounded probe, the principle proceeded to by spiral inserts a probe in soil, can
A difficult problem relatively difficult in the local insertion soil that soil property is harder effectively to solve grounded probe.
Technical scheme is as follows:
Novel grounded resistance measuring instrument grounded probe, it is characterised in that include handle, annulus and probe, described
Probe tip be welded with annulus, the upper end of probe welding one connection cross bar, the described two ends connecting cross bar
It is connected with described handle release formula respectively.
Wherein, described detecting probe surface is provided with spiral lamination.
Wherein, described handle is connected with probe by the way of grafting or buckle.
Wherein, described probe length is 50cm.
Wherein, the quantity of described handle is two, a length of 250cm of every.
Wherein, described annulus is connected with the connecting line of ground resistance measuring instrument, and circle diameter is 1.5cm.
Beneficial effects of the present invention is as follows:
The present invention applies the corollary equipment of the ground resistance measuring instrument at built on stilts defeated, distribution line pole tower, puts into little,
Low cost, carries out technological innovation to former ground resistance measuring instrument grounded probe, has convenient disassembly, it is easy to take
The feature of band, helps earth resistance personnel easily and efficiently by the grounded probe of earth resistance tester
Insert in soil, reduce labor intensity and the danger of earth resistance personnel, be effectively improved labor efficiency,
And surface is provided with the probe of spiral lamination and adds the contact area of grounded probe and soil, makes earth resistance
Measured value is more accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.

As in figure 2 it is shown, during the overhead line structures such as defeated, distribution are carried out earth resistance, by figure institute
Showing and be connected with grounding device and two grounded probes by the terminal of ground resistance measuring instrument, Novel grounded probe exists
During use, first by two detachable handles 1 by the way of grafting or screw thread are twisted joint and on grounded probe 3
Connecting cross bar 4 to be connected, then by the way of being rotatably inserted into, go underground appropriate depth by grounded probe 3,
Then the connecting line annulus 2 of the connecting line of earth resistance with grounded probe 3 upper end is connected, thus may be used
To carry out earth resistance.
Embodiment 2
Novel grounded resistance measuring instrument grounded probe, including handle 1, annulus 2 and probe 3, handle 1 passes through
The mode of buckle is connected with being connected cross bar 4, and other parts are with embodiment 1.
It should be noted that the present invention is not restricted to the described embodiments, above-described embodiment and description are retouched
The principle that the present invention is simply described stated, without departing from the spirit and scope of the present invention, the present invention is also
