Abstract
The utility model relates to a supporting earth device for an insulator, which belongs to a special safety appliance of a power supply system in electric power industry. The utility model is mainly composed of an insulator upper conductor mounting seat (6), an insulating body (7) and a base (8), wherein the top end of the insulator upper conductor mounting seat (6) is provided with a bolt (3), and a cushion ring (4) is fixedly provided with a strip-shaped earth drainage board (2). One end of the earth drainage board (2) is made into a column-shaped earth hanging rod (1), and the other end is provided with a conductor mounting hole (5). The supporting earth device for the insulator has simple and reliable structure which is equivalent to the extension of the function of the insulator. The utility model has the advantages of convenient installation, no obscission phenomenon of an earth ring and maintenance-free. Because of the hard connection of the position hanging an earth wire, the utility model can not cause the looseness and the deformation of a first bus and a secondary bus of a transformer platform. The large contact area of the earth drainage board and the conductor can satisfy the thermal stability and the electrical dynamic stability while in short circuit. The earth wire can be hung more firmly to protect the safe operation of the power supply line and the personal safety of the installation personnel.
Description
Technical field
The utility model belongs to the special-purpose safety appliance of power industry electric power system, particularly a kind of supporting insulator earthing device.
Technical background
0.4KV～10KV line outage operation or transformer platform power failure operation hanging ground-wire are most important links in the various safety measures, the ground connection gold utensil of insulated conductor is mainly used earthing clamp, traditional earthing clamp mainly is made up of wire clamp and ground loop, though pattern is various, but all be mounted on the lead, the pulling force when making lead bear earthing clamp deadweight and earth connection and the gravity of earth connection, transformer one, earthing clamp can cause bus or the loose distortion of lead on secondary bus and the 0.4KV circuit in the hanging ground-wire process, degree of speeding becomes the potential safety hazard that exists broken string greatly, earthing clamp connects with bolt simultaneously, after operation a period of time, the ground loop obscission is arranged, the quality that articulates of earth connection is had a strong impact on, if the circuit broken string not only influences the life security that power supply also may threaten the pedestrian, the people need visit the insulating cover that waist divests the insulated conductor joint earlier on bar when the 0.4KV circuit is installed ground wire in addition, electrical verification again, hanging ground-wire, labour intensity is big, do not meet first electrical verification, the operating sequence of back hanging ground-wire, totally unfavorable to personal safety.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of safe and reliable supporting insulator earthing device is provided.
The technical scheme that the utility model technical solution problem adopts is: the supporting insulator earthing device is mainly by insulator, insulator upper conductor mount pad, base is formed, be characterized at insulator upper conductor mount pad top bolt, packing ring fixedly is equipped with bar shaped ground connection drainage plate, make cylindricality ground connection peg at ground connection drainage plate one end, the other end is provided with the lead installing hole, the ground connection peg is made the right angle hook-type, half " worker " font becomes vertical rectangular arc with the ground connection peg with the ground connection drainage plate, insulating case is equipped with in peg portion, ground connection drainage plate and insulator upper conductor mount pad are equipped with insulating cover, and hot galvanizing is carried out at the peg position.
The beneficial effects of the utility model are: the supporting insulator earthing device is simple and reliable for structure; be equivalent to the extension of insulator function; easy for installation; the position that adds hanging ground-wire connects for hard; can not cause the lax distortion of transformer platform first and second bus; there is not the ground loop obscission; non-maintaining; ground connection drainage plate and lead conductor contact area are big; thermal stability in the time of satisfying short circuit and electric power stability; ground wire hitching is more firm, the personal safety of protection supply line's safe operation and installation personnel.
