Abstract
The utility relates to a lightning shielding device, especially a distributed small-size lightning shielding device comprising lightning rod, earthing wire; the lightning rod is multi-point distributed and fixed on protected article through its fixing bracket; a earthing wire is fixed on the protected article through conducting fastener; each lightning rod is electrically connected with the earthing wire. The lightning shielding device of the utility can avoid lightning of all time, especially for rolling thunder; the lightning rod is multi-point distributed and adapts to cable guide or truss of power supply system and control system; the cable guide and cable truss can be used as conductor; small system multi-point lightning rod is adopted, which has good shielding effect and costs far below other lightning shielding system.
Description
Technical field:
The utility model relates to arrester device, the small-sized lightning arrester of especially a kind of collective and distributive type.
Background technology:
Lightning tower in the past can only branch be arranged, when running into some special thunders and lightnings (as rolling mine), can not play effectively lightning-arrest effect.
The utility model content:
The utility model is intended to solve that existing lightning tower branch is arranged, the problem of lightning-arrest weak effect, and provide a kind of can large tracts of land, arrange in the wide scope, can effectively prevent the small-sized lightning arrester of collective and distributive type of special thunder and lightning thunderbolts such as rolling mine.
The technical scheme that the utility model addresses the above problem employing is: the small-sized lightning arrester of a kind of collective and distributive type; comprise lightning rod, earth lead; described lightning rod is multiple spot and distributes, all is fixed on the protected object by its fixed mount; an earth lead is fixed on the protected object by its conduction clamp, and each lightning rod all is electrically connected with this earth lead.
Compared with prior art, the beneficial effects of the utility model are: can avoid the generation of the thunderbolt time of all kinds, especially the most difficult rolling mine of avoiding also be had good shield effectiveness; Its lightning rod is the multiple spot distribution form, cable testing bridge or cable truss in suitable especially electric power system and the control system are installed and used, and can utilize cable testing bridge and cable truss to be conductor, take mini system multipoint mode lightning rod, shield effectiveness is good, and its cost is well below other lightning protection systems.
Description of drawings:
Structural representation when Fig. 1 installs and uses on cable testing bridge for the utility model.
Structural representation when Fig. 2 installs and uses on the cable truss for the utility model.
Fig. 3 is an A portion enlarged drawing among Fig. 2.
Fig. 4 is a B portion enlarged drawing among Fig. 2.
Among the figure: lightning rod 1, fixed mount 2, stainless steel bolt 3, earth lead 4, conduction clamp 5, cable testing bridge 6, cable truss 7.
Embodiment:
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
As shown in Figure 1, lightning rod 1 is fixed on the cable testing bridge 6 by the fixed mount 2 and the connecting bolt thereof that can conduct electricity, and cable testing bridge 6 is made by the steel material that can conduct electricity, and its surface scribbles anticorrosive coat.An earth lead 4 is fixed on the cable testing bridge 6 by stainless steel bolt 3 by its conduction clamp 5.Lightning rod 1 distributes for multiple spot, and each lightning rod 1 is all by its fixed mount 2 and connecting bolt and cable testing bridge 6 bodies formation electric conductor.Equally, earth lead 4 has also constituted an electric conductor by its conduction clamp 5 and stainless steel bolt 3 with cable testing bridge 6 bodies.Like this, when the thunderbolt incident took place, thunder and lightning at first contacted with lightning rod, and then directly electric current is emitted by earth lead 4 by cable testing bridge 6 bodies.
As shown in Figure 2, lightning rod 1 is fixed on the cable truss 7 by the fixed mount 2 and the connecting bolt thereof that can conduct electricity, and cable truss 7 is made by the steel material that can conduct electricity, and its surface scribbles anticorrosive coat.An earth lead 4 is fixed on the cable truss 7 by stainless steel bolt 3 by its conduction clamp 5.The same with discharge principle shown in Figure 1, when the thunderbolt incident took place, thunder and lightning at first contacted with lightning rod, and then directly electric current is emitted by earth lead 4 by cable truss 7 bodies.
When on cable testing bridge 6 or cable truss 7, above-mentioned lightning arrester being installed, lightning rod 1 is arranged for multiple spot, each lightning rod 1 can a shared earth lead 4, also can be that each lightning rod 1 is connected with cable testing bridge 6 or cable truss 7 bodies with an earth lead 4 respectively but as required.Certainly, when cable testing bridge 6 or cable truss 7 adopts non-conducting materials to make, lightning-arrest lead 1 with earth lead 4 between must be connected with lead, lead to guarantee to take shelter from the thunder 1 and earth lead 4 between good electrical conductivity is arranged.
