Description
Technical field
The utility model relates to a kind of earthing device in the electric power system.
Background technology
In electric power system, need install earth connection when circuit repairing, construction, be the technical measures of guarantee of work safety on power circuit.When the installing earth connection, need grounding nail is installed, thereby grounding nail is to use electric operating instrument more widely.Usually in installing during earth connection,＜＜the line security rules〉require ground connection to want 60 centimeters ability qualified with hammering into.Because Fuping County is located in the depths, Taihang Mountain; high mountain range, mountain macroclimate complexity; it is freezing just to have entered the earth change in November every year; May in the coming year the earth freezing just the thawing; during this period, when circuit repairing, construction, the dismounting earth connection is required great effort very much; whole grounding nail will be pounded with sledgehammer fully; just can throw ground into, and that grounding nail is often pounded is curved, the earth connection connecting hole is also pounded disconnected through regular meeting; the degree of depth is difficult to reach the rules requirement; during taking-up, because the grounding nail bending in the ground, need sometimes just can dig out with crowbar, spade; process wastes time and energy, and influences operating efficiency.
The utility model content
Technical problem to be solved in the utility model provides a kind of quick construction, standard, can effectively increase work efficiency and the special-purpose earth connection instrument of power supply reliability.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of earth connection is installed the dedicated fixed grounding nail, comprises the grounding nail main body, it is characterized in that described grounding nail main body is angle steel, and the angle steel lower end is the inclined-plane wedge angle, and the angle steel upper end is provided with the earth connection connecting hole.
Described earth connection connecting hole is 2.
Described earth connection connecting hole is provided with fastening bolt.
The beneficial effect that adopts technique scheme to produce is: the utility model combines original grounding nail
Operation easier is big, the difficult shortcoming such as up to standard of the degree of depth, provides a kind of earth connection that the dedicated fixed grounding nail is installed, and adopts the angle steel cutting to form, material is easy to get, with low cost, have the advantage of quick construction, standard, realization permanent fixation, the reliability that can effectively increase work efficiency and power.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
1, grounding nail main body, 2, the earth connection connecting hole.
Embodiment
The utility model discloses a kind of earth connection the dedicated fixed grounding nail is installed, comprise the grounding nail main body, it is characterized in that described grounding nail main body 1 is angle steel, the angle steel lower end is the inclined-plane wedge angle, the angle steel upper end is provided with earth connection connecting hole 2, described earth connection connecting hole 2 is 2, and described earth connection connecting hole 2 is provided with fastening bolt.
In the power construction process, earthing device is the general name of earth electrode and earth connection, and its effect is conducting lightning currents to be imported underground, and the protection of lightning-protection system is relevant therewith to a great extent.The characteristics of earth work itself have just determined the influence of surrounding environment to engineering effort, and having broken away from the on-site concrete condition of engineering, to design earth work be infeasible.Practice require to want systematic ground connection theory to instruct engineering is actual, and the quality of design depends on taking all factors into consideration many factors of local soil environment.But factors such as soil resistivity, soil layer construction, moisture situation and construction area have determined the selection of ground network shape, size, process materials.Therefore when the artificial earth electrode is designed, should accurately design according to geological conditions such as the on-site soil resistivity of earth mat, clay distribution as far as possible.
Earth electrode: claiming earth electrode again, is metallic conductor or the conductor group who directly contacts with soil.Be divided into artificial earth electrode and natural junctor.Earth electrode as contact closely with the earth soil and provide and the earth between the conductor that is electrically connected, the diffusing stream of safety thunder energy leaks in the design of the earth ground connection it, utilizing has reliable various metal structures, pipeline and the equipment that is connected as earth electrode with ground, is called natural grounding substance.If the resistance of natural grounding substance can meet the demands natural grounding substance is produced potential safety hazard, when not having peremptory norm, just can be used for doing earth electrode.
And the people imbeds underground conductor as earthing device, is called the artificial earth electrode.The metal object that generally will meet the grounding requirement cross section is imbedded the underground of the suitable degree of depth, and resistance requirement up to specification is then as earth electrode.Specifically with reference to grounding specifications, lightning protection, equipment ground, electrostatic grounding etc. need distinguish.
Ground connection is the most important link of lightening protection engineering, no matter be direct lightning strike protection or the guard technology of the electrostatic induction of thunder and lightning, electromagnetic induction and lightning surge intrusion, finally all is that lightning current is sent into the earth.Therefore do not have good grounding technology, qualified anti-ray process just can not be arranged.The effect of protective earthing is exactly that the uncharged metal of electric equipment partly with between the earth electrode is connected as good metal, reduces the voltage to earth of contact, avoids human electric shock's danger.
The utility model has adopted waste and old material to utilize scheme: the length 1.9m cross-arm with waste and old, the inclined-plane wedge angle is cut into cutting machine in the lower end, and the circular hole of two diameter 16mm is made a call to as the earth connection connecting hole by 2-3cm place, last end distance termination.During use with direct permanent next the basic electric pole subsurface that is fixed in the dead line switch of grounding nail main body inclined-plane wedge angle, distance is outside next basic electric pole mains side 1.5m, the upper end bassets about 5 to 6cm, and the earth terminal of earth connection is connected with the earth connection connecting hole, fixes with fastening bolt.Ground is dark, contact area is big owing to the earth connection installation dedicated fixed ground connection of making of old cross-arm hammers into, and installs grounding nail originally and wants more than 20 minute, and is present only with one or two minute, quick construction, standard.
