Abstract
The utility model discloses step-down lightning rod comprises lightning rod, step-down coil, shielding pipe, owing to be equipped with step-down coil between lightning rod and earth connection, when can making the thunder and lightning pass through step-down coil, make electric current and voltage all reduce by a wide margin, consequently avoided owing to the strong electromagnetic field that produces around the earth connection is to the secondary thunderbolt of protection facilities, is equipped with shielding pipe outside step-down coil, has solved the magnetic field radiation problem that the lightning current got into step-down coil and produced. The utility model discloses simple structure solves the secondary thunderbolt and the magnetic field radiation problem of thunder and lightning effectively, has practicality and spreading value.
Description
Technical field: the utility model relates to a kind of lightning arrester.
Background technology: traditional lightning arrester is installed pinnacled lightning rod and directly is connected with the earth by earth connection; though this lightning arrester can reduce the directtissima destruction of thunder and lightning to the protection facility; but when powerful lightning current passes through earth connection; around earth connection, produce very strong electromagnetic field; intensity of lightning is big more, and magnetic field is big more, thereby the normal secondary thunderbolt that constitutes communications facility; very easily cause device damage, influence normal operation.
Summary of the invention: for solving traditional lightning arrester to protection facility generation secondary thunderbolt problem, the utility model provides a kind of lightning rod that can effectively prevent the secondary thunderbolt simple in structure.
The technical scheme that the technical problem that the utility model solved is taked: the utility model buck lightning rod, comprise lightning rod, earth connection, it is characterized in that: lightning rod is contained on the lightning rod base, the lightning rod base is fixed on the High-Voltage Insulation porcelain spare, be fixed with shielded-plate tube in High-Voltage Insulation porcelain spare lower end, be built-in with insulated tube at shielded-plate tube, on insulated tube, be tied with diminishing coil, diminishing coil just end line is connected with down conductor system one end, the down conductor system other end is positioned on the lightning rod base, be equipped with the earth connection screw in the shielded-plate tube lower end, diminishing coil tag wire and earth connection one end are fixed on the earth connection screw.
Between lightning rod and lightning rod base, the metal finishing ball can be housed, install, and increase aesthetic feeling with the lightning rod that is suitable for different directions.
Shielded-plate tube is a metal tube, can be steel pipe, copper pipe.
The beneficial effects of the utility model: the utility model is owing to string between lightning rod and earth connection has diminishing coil; can make the moment of lightning current by diminishing coil; diminishing coil forms a reactance to lightning current; lightning current is reduced; diminishing coil can produce self-induced e.m.f at lightning voltage again by moment simultaneously; offset with thunder and lightning; thereby it is very low that lightning voltage is reduced to behind diminishing coil; electric current is very little; be not enough to cause the secondary thunderbolt; shielded-plate tube is housed outside diminishing coil, shielded-plate tube is connected with earth connection, has solved lightning current and has entered the magnetic field radiation problem that diminishing coil produces diminishing coil is played a protective role.The utility model is simple in structure, solves the secondary thunderbolt and the magnetic field radiation problem of thunder and lightning effectively, has practical and popularizing value.
Description of drawings:
Fig. 1 is a buck lightning rod structural representation.
Among the figure 1, lightning rod; 2, ornament ball; 3, lightning rod base; 4, High-Voltage Insulation porcelain spare; 5, screw; 6, down conductor system; 7, insulated tube; 8, diminishing coil; 9, shielded-plate tube; 10, lightning tower; 11, earth connection; 12, earth connection screw.
Embodiment of the present utility model: be described with reference to the accompanying drawings buck lightning rod structure, install and use.Lightning rod 1 is installed on the stainless steel ornament ball 2, and lightning rod can be 1 or several.Stainless steel ornament ball 2 is fixed on the metallic lightning rod base 3, adpting flange on the lightning rod base 3 and High-Voltage Insulation porcelain spare 4 fix with screw 5, flange in High-Voltage Insulation porcelain spare 4 lower ends and steel shielded-plate tube 9 upper ends is connected to a fixed with screw 5, insulated tube 7 is housed in shielded-plate tube 9, on insulated tube 7, be tied with diminishing coil 8, down conductor system 6 one ends are connected on the lightning rod base 3, the other end is connected with the first end line of diminishing coil 8, end flanges is equipped with earth connection screw 12 under the shielded-plate tube, one end of diminishing coil 8 tag wires and earth connection 11 is fixed on the earth connection screw 12, earth connection 11 other ends are connected on the earthing conductor, earthing conductor is imbedded underground, and end flanges is fixed on the lightning tower 10 with screw 5 and earth connection screw 12 under the shielded-plate tube.
Thunder and lightning reaches the earth through lightning rod, lightning rod base, down conductor system, diminishing coil, earth connection.
