Abstract
The invention provides a lightning arrester grounding rod comprising a core rod formed by high-melting-point metal. The upper end of the core rod is provided with a wiring terminal, and the lower end is conical. The side wall of the core rod is wrapped by a metal wall formed by low-melting-point metal. According to the lightning arrester grounding rod, a surface oxide layer can be automatically eliminated, and maintenance is not required in a long period of time so that maintenance cost can be greatly reduced.
Description
Technical field
The present invention relates to electric power facility field, especially, is a kind of arrester ground rod.
Background technology
For current arrester ground rod, what generally adopt is a fixing metal bar, is generally made up of copper rod, iron staff or alloy bar, directly inserts underground, and its upper end connects lightning arrester.Because underground environment is comparatively severe, therefore easily make earth rod surface be oxidized, earth resistance is increased, as processed this problem not in time, then, when there is thunderbolt, lightning arrester just normally cannot protect electric equipment.And a current earth rod just fixing homogeneous metal bar substantially, after oxidation, must pull out and carry out repair process, or directly adopt the replacement of new earth rod, maintenance cost is higher.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of arrester ground rod, this arrester ground rod can eliminate surface oxide layer automatically, Maintenance free in a long time, and maintenance cost can be made significantly to reduce.
The technical scheme that actualizing technology object of the present invention adopts is: this arrester ground rod comprises the plug be made up of dystectic metal; The upper end of described plug has binding post, and lower end is tapered; The sidewall of described plug is enclosed with the metallic walls be made up of the metal of low melting point.
As preferably, described dystectic metal is that copper or iron or stainless steel are formed; The metal of described low melting point is made up of aluminium or power insurance wire material.
As preferably, be also provided with an articulamentum between described plug and metallic walls, the alloy that described articulamentum is made up of the material of described plug and the material of described metallic walls is formed, thus makes the electric connection of described plug and metallic walls more stable.
As preferably, described plug is the tubulose of closed at both ends, and the corrugated that its cross section is centrosymmetric, form circumferential ripple struction, and there is the elastic prestress that described plug circumference is outwards expanded in described circumferential ripple struction.
As the further improvement of above-mentioned optimal way, described plug inside is also closed with boiling point at the liquid of 50 DEG C ~ 150 DEG C; As ethanol, water etc.
Beneficial effect of the present invention is: this arrester ground rod is when accepting thunderbolt, metal wall surfaces as earth rod is oxidized, resistance to earth is caused to increase, then oxidized surface is hot rapidly, metal wall surfaces is caused to melt, thus oxide layer is destroyed, form new metallic walls after condensation, make it to form good ground connection; Therefore, this earth rod, when not adding maintenance, can keep lower resistance to earth all the time.
Accompanying drawing explanation
Fig. 1 is the structural representation of this arrester ground rod embodiment one.
Fig. 2 is the cross sectional representation of this arrester ground rod embodiment two.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In embodiment illustrated in fig. 1 one, arrester ground rod comprises the plug 1 be made up of dystectic metal; The upper end of described plug 1 has binding post 10, and lower end is tapered; The sidewall of described plug 1 is enclosed with the metallic walls 2 be made up of the metal of low melting point.
Above-mentioned arrester ground rod, described dystectic metal is that copper or iron or stainless steel are formed, and fusing point is more than 1500 DEG C; The metal of described low melting point is made up of aluminium, and fusing point is at about 660 DEG C; This low-melting-point metal also can be made up of fuse material, but when adopting fuse material to form, flows through thunder-strike current at every turn, and all solidify once by fusing, make the consumption of metallic walls very fast, useful life is not so good as aluminium.
Above-mentioned arrester ground rod is when accepting thunderbolt, as metallic walls 2 surface oxidation of earth rod, resistance to earth is caused to increase, then oxidized surface is hot rapidly, cause metallic walls 2 surface melting, thus oxide layer is destroyed, new metallic walls is formed after condensation, period, due to the Gravitative Loads of liquid metal, just can condense into solid-state after being close to earth rod and earth surfaces completely, therefore, the new metallic walls formed afterwards in condensation is inevitable keeps good in electrical contact with plug 1 and earth surfaces, makes it to form good ground connection; This earth rod visible, when not adding maintenance, can keep lower resistance to earth all the time.
For the embodiment two shown in Fig. 2, the difference of itself and embodiment one is: the tubulose of described plug 1 in closed at both ends, and the corrugated that its cross section is centrosymmetric, form circumferential ripple struction, and there is the elastic prestress that described plug circumference is outwards expanded in described circumferential ripple struction.
In order to realize the elastic pre-stress of described ripple struction, described earth rod can be made as follows: one, adopt mould or extruder to make the tubulose plug with described circumferential ripple struction; Two, adopt fixture the tubulose plug circumference in step one to be stepped up, the radially-inwardly deformation of described ripple struction, form constrained strain plug; Three, in the described metallic walls of described deformation constraint plug outside casting; Four, described fixture is removed; Five, partial operation finishing.
Because described plug 1 has the outside elastic prestress expanded of circumference, therefore under metallic walls 2 molten condition, plug 1 can pass through this elastic prestress, metallic walls 2 is outwards extruded, promotes itself and earth surfaces close contact.
Further, described plug 1 inside is also closed with boiling point at the liquid of 50 DEG C ~ 150 DEG C; As ethanol, water etc.; Then when resistance to earth is larger, because earth rod temperature must more than 50 DEG C, described liquid can form rapidly huge internal pressure, promotes the radial expansion trend of plug 1 further, makes described metallic walls 2 keep excellent contact with earth surfaces.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
