Abstract
The utility model relates to the technical field of earthing devices for public change earth resistance measurement, specifically to a temporary earthing device for public change earth resistance measurement. The temporary earthing device for public change earth resistance measurement comprises an earth tongs, an earth electrode and a lead. One end of the lead is fixedly connected with the earth tongs, and the other end of the lead is fixedly connected with the earth electrode. The temporary earthing device provided by the utility model has a reasonable and compact structure and is convenient to use. During the process of measuring public change earth resistance, measuring time of distribution public change earth resistance is shortened, work efficiency of workers is raised, and personal safety of workers is guaranteed. The temporary earthing device is convenient to carry and provides a strong guarantee for safe operation of a distribution line.
Description
Technical field
the utility model relates to the public grounding resistance measurement earthing device technical field that becomes, and is a kind of public grounding resistance measurement temporary earthing device that becomes.
Background technology
at present, the distribution line of electrical network has broad covered area, circuit branch is many and substation transformer characteristics how.Further lifting along with the distribution specialized management, for the distribution technique group, the problem that distribution line in its compass of competency occurs is more and more, yet because distribution line is complicated and the staff is few, cause the staff can not process in time the problem of finding in distribution line, again because the public quantity become is many now, must become stake resistance to public affairs and carry out regular measurement every year, Measuring Time is longer, thereby strengthened staff's workload, and, in the process of distribution line operation and maintenance, there is the risk of personal safety in the staff.
Summary of the invention
the utility model provides a kind of public grounding resistance measurement temporary earthing device that becomes, overcome the deficiency of above-mentioned prior art, it can effectively solve the existing public problem that there is personal safety in long and staff of the public time that becomes stake resistance of measurement distribution that the grounding resistance measurement earthing device exists in actual use that becomes.
the technical solution of the utility model realizes by following measures: a kind of public grounding resistance measurement temporary earthing device that becomes, comprise ground connection pincers, earthing pole and wire, one end of wire and ground connection pincers are fixed together, and the other end and the earthing pole of wire are fixed together.
below the further optimization and/or improvements to above-mentioned utility model technical scheme:
one end of above-mentioned wire and ground connection pincers can be fixed together by the line nose, and the other end of wire and earthing pole are fixed together by the line nose.
above-mentioned ground connection pincers be with together with the line nose can be mounted by means of bolts on, and earthing pole is with together with the line nose is mounted by means of bolts on.
above-mentioned wire can be copper cash.
the diameter of above-mentioned copper cash can be 25 millimeters, and the length of copper cash is two meters.
the utility model reasonable and compact in structure, easy to use, it is in the process of measuring public change stake resistance, shorten the public Measuring Time that becomes stake resistance of distribution, improved staff's work efficiency, guaranteed staff's personal safety, easy to carry, for the safe operation of distribution line provides strong guarantee.
The accompanying drawing explanation
the main TV structure schematic diagram that accompanying drawing 1 is the utility model most preferred embodiment.
coding in accompanying drawing is respectively: 1 is the ground connection pincers, and 2 is earthing pole, and 3 is wire, and 4 is the line nose.
Embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all to be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, these public affairs become the grounding resistance measurement temporary earthing device and comprise ground connection pincers 1, earthing pole 2 and wire 3, and an end of wire 3 and ground connection pincers 1 are fixed together, and the other end of wire 3 and earthing pole 2 are fixed together.Ground connection pincers 1 and earthing pole 2 are existing known technology.
can according to actual needs, the above-mentioned public grounding resistance measurement temporary earthing device that becomes be made further optimization and/or improvements:
as shown in Figure 1, an end of wire 3 and ground connection pincers 1 are fixed together by line nose 4, and the other end of wire 3 and earthing pole 2 are fixed together by line nose 4.The setting of line nose 4 can make ground connection pincers 1 and earthing pole 2 more firm with being connected of wire 3.
as shown in Figure 1, ground connection pincers 1 are with together with line nose 4 is mounted by means of bolts on, and earthing pole 2 is with together with line nose 4 is mounted by means of bolts on.
as required, wire 3 is copper cash.
as required, the diameter of copper cash is 25 millimeters, and the length of copper cash is two meters.
above technical characterictic has formed most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs non-essential technical characterictic, meets the demand of different situations.
the use procedure of the utility model most preferred embodiment: at first, the staff wears the electrical isolation gloves, then by the broken osculum of original ground wire, make it at the osculum place, expose the metal position, earthing pole 2 is inserted in accordance with regulations undergroundly simultaneously, then clamp exposed metal position, ground wire place with ground connection pincers 1, take original earthing clamp apart and carry out grounding resistance measurement, after measurement, by the osculum place, exposed metal position is wound around with insulating tape, recovers its original appearance.
