Description
Technical field
The utility model relates to a kind of high-and low-voltage circuit upkeep operation ground connection body, belongs to the electric power overhaul technical field.
Background technology
at present, in carrying out the high-and low-voltage circuit upkeep operation, general use earth electrode ground connection in high-low pressure earth connection process used, " safety " 4.4.7 bar regulation, earth electrode is inaccurate less than 0.6 meter in the subsurface degree of depth, in real work, the earth electrode that background technology is used, owing to being that single hole is connected with earth connection, bolt is easily lax, and the staff can not accurately hold earth electrode and enter the ground degree of depth, the problem such as Kong Chu position damage when tending to occur earth electrode and entering ground degree of depth deficiency and attack and squeeze into ground, also some staff does not grasp " safety " regulation, think as long as ground connection, the problem of having ignored the ground connection degree of depth, bring hidden danger for the personal safety of staff in line maintenance.The high-and low-voltage circuit upkeep operation, mobility is strong, also needs earth electrode to be easy to carry, and reuses, and facilitates installation and removal, shortens the repair time.
The utility model content
The utility model purpose is to provide a kind of high-and low-voltage circuit upkeep operation ground connection body, is easy to carry, and reuses, facilitate installation and removal, shorten the repair time, guarantee safety ground, eliminate safe hidden trouble, improve safety and reliability, solve the problems referred to above that background technology exists.
The technical solution of the utility model is:
A kind of high-and low-voltage circuit upkeep operation ground connection body comprises earth brace, impacts cross bar and terminal block, and described earth brace lower end is conical structure, arranges on earth brace and impacts cross bar, impacts cross bar and earth brace is arranged vertically; Be on the earth brace of conical structure summit 61 centimeters, close ring to be set one in the distance lower end, enter ground mark as minimum; On the earth brace above close ring, terminal block is set, two connecting holes are set on terminal block, connecting hole is installed with bolt, and bolt coupling nut is used for connecting earth connection; Also be provided with direction board on described terminal block, direction board is corresponding with the close ring on earth brace, reminds and indicate position and the effect of close ring.
Close ring on described earth brace is for going out the close ring of groove shape by machined into.
The described mid point that impacts cross bar and earth brace upper end weld together, and bear conveniently that attack impacts and the later stage is removed portable extracting with entering; Connecting plate and earth brace weld together.
1.5 centimetres of described earth brace diameters, 87 centimetres of length impact 1.5 centimetres of cross bar diameters, 12 centimetres of length.
When the high-and low-voltage circuit upkeep operation needs ground connection, check the direction board on the Special grounding wire earth electrode, find the close ring that enters ground mark as minimum; Then with the downward kiss the earth of conical structure of earth brace lower end, firmly impact the cross bar that impacts of earth brace upper end, earth brace enters ground, enters the ground degree of depth and surpasses the close ring that enters ground mark for minimum; The end of earth connection first is connected on the connecting plate of diplopore, and two connecting holes on the diplopore of terminal block and connecting plate are complementary, and by two bolt and nuts, terminal block and connecting plate are fixed together, and complete ground connection; After the high-and low-voltage circuit upkeep operation is completed, unclamp the bolt on connecting plate, pull down connecting plate and earth connection; Both hands are held the two ends that impact cross bar, firmly earth brace are extracted from underground, reuse next time again.
Good effect of the present utility model: be easy to carry, reuse, facilitate installation and removal, shorten the repair time, be specially adapted to high-and low-voltage circuit upkeep operation ground connection, guarantee safety ground, ground connection is solid and reliable, eliminate safe hidden trouble, meet the relevant security regulations of country fully, improve safety and reliability.
