Tree line contradiction in change, has beautified urban look；Improve the utilization rate of line channel；Prevent environment filthy for wire
Directly affect；And there is good Social benefit and economic benefit.But, the most relevant statistics shows；Insulation is led
Line is in operation, and its total failare number is about the 15% of bare conductor number of faults, and number of faults is greatly reduced, but insulated conductor suffers thunder
The probability hit is few unlike bare conductor, and the probability of lightning-caused breaking increases.
But, existing line overvoltage protection device is not in the case of having other fixing, along with the swing of wire, and
The effect of other external force such as wind-force, may make current limliting original paper be connected strut plate with scalable or scalable connects strut plate and cross-arm
Between connection loosen, cause current limliting original paper deviate origin-location, cause between wire drainage ball and current limliting original paper drainage ball
Distance increases, and when there is Lightning Over-voltage, not having and making gap breakdown thus by the mesh of current limliting original paper release thunder energy
's.
Utility model content
The purpose of this utility model is to provide a kind of line overvoltage protection device, to solve to propose in above-mentioned background technology
Along with the swing of wire, and the company that the lower current limliting original paper of effect of other external force such as wind-force is connected between strut plate with scalable
Connect loosening, when there is Lightning Over-voltage, not having and making gap breakdown thus by the purpose of current limliting original paper release thunder energy
Etc. problem.
For achieving the above object, this utility model following technical scheme of offer: a kind of line overvoltage protection device, including limit
Fluid element drainage ball and ceramic protective sleeve, the inner upper end of described ceramic protective sleeve embeds and is provided with wire drainage ball, described in lead
Line drainage ball is arranged on the middle position below retaining element, and being internally embedded of described retaining element is provided with wire, described
Current limiting element drainage ball embeds the middle position being arranged on the lower end within ceramic protective sleeve, and current limiting element drainage ball and sets
It is equipped with Zinc-Oxide Arrester, between described wire drainage ball and current limiting element drainage ball, is provided with hollow inner bag, described current limliting unit
The lower section of part drainage ball is provided with ground strip, and described wire drainage ball is electrically connected with wire.
Preferably, the distance between described wire drainage ball and current limiting element drainage ball is 5cm.
Preferably, described hollow inner bag composition the air gap.
Preferably, described ground strip is electrically connected with ground.
Preferably, described wire drainage ball and current limiting element drainage ball are spherical structure.
Compared with prior art, the beneficial effects of the utility model are: this line overvoltage protection device is at original protector
On the basis of improved, simple in construction, easy to use, existing equipment will not be caused damage；Simultaneously because increased newly absolutely
Edge ceramic sheath, is wrapped up wire drainage ball and current limliting original paper drainage ball, is prevented the metal surface that rain drop erosion causes
Oxide etch, provides certain protection for extending its service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-wire drainage ball, 2-current limiting element drainage ball, 3-retaining element, 4-wire, 5-ceramic protective sleeve, 6-
Hollow inner bag, 7-Zinc-Oxide Arrester, 8-ground strip.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of technical scheme of this utility model offer: a kind of line overvoltage protection device, including current limliting unit
Part drainage ball 2 and ceramic protective sleeve 5, the inner upper end of ceramic protective sleeve 5 embeds and is provided with wire drainage ball 1, wire drainage ball 1
Being arranged on the middle position below retaining element 3, being internally embedded of retaining element 3 is provided with wire 4, current limiting element drainage ball
2 embed the middle position being arranged on the lower end within ceramic protective sleeve 5, and current limiting element drainage ball 2 is provided with zinc oxide
Spark gap 7, is provided with hollow inner bag 6, the lower section of current limiting element drainage ball 2 between wire drainage ball 1 and current limiting element drainage ball 2
