Description
Technical field
The utility model belongs to composite cross-arm insulator string field, more particularly, relates to a kind of composite cross-arm insulator string being suitable for high altitude localities band clearing apparatus.
Background technology
High-voltage fence operation troubles is mostly caused by defective insulation, and high-voltage fence insulator is the weak link of high-voltage fence insulation.Pollution flashover acquires a certain degree caused by the pollution severity of insulators state of making moist, and is a kind of common phenomenon occurred in high-tension line and transformer station, is that of electric power netting safe running threatens greatly.Because the harmfulness of pollution flashover accident is large, area is wide, and once large accident often causes many, areal circuit to trip simultaneously, and therefore power department will prevent pollution flashover accident to be used as the important process of electric power system guarantee safe operation.
Domesticly at present carry out antifouling work work and mainly concentrate on and anti-pollution type insulator is installed, to the regular cleaning of insulator, strengthens retting-flax wastewater, brushing RTV coating etc., but these methods are all passive or regular enforcement.Meanwhile, do not propose the anti-fouling method installing clearing apparatus on the insulator additional, do not produce the insulator of band clearing apparatus yet.Along with the aggravation of present air environmental pollution and the deterioration of weather conditions, existing anti-pollution measure can not adapt to the requirement of antifouling work completely.Such as, strengthen retting-flax wastewater and be subject to the restriction of current conditions, be difficult to the gradation for surface pollution determining each area, can not unconfined increase retting-flax wastewater; Although brushing RTV coating can obtain certain effect, RTV coating has certain term of validity, and a large amount of brushings repeated can increase the weight of the burden of administrative department; Planned regular cleaning can not stop the generation of pollution flashover, and sometimes before cleaning, circuit just there occurs pollution flashover accident.China Patent No. is 201220704625.2 disclose a kind of composite cross-arm insulator string being applicable to high altitude localities, though it can by clean for insulator surface cleaning, it exists following defect: 1, complex structure, makes trouble and cost is higher; 2, in Long-Time Service situation, the junction of described fan blade and cleaning sheet easily occurs to rupture and even comes off, thus significantly reduces the useful life of this product; 3, fan blade is more, easily chaotic when rotating under wind blows, thus fan blade and fan blade can be easy to occur reverse wind-force each other, greatly weak wind-force blowing cleaning sheet, thus reduces sweeping efficiency.
Utility model content
the problem that 1, will solve
For the above-mentioned problems in the prior art, the utility model provides a kind of composite cross-arm insulator string being suitable for high altitude localities band clearing apparatus, it is by fan-shaped cleaning leaf, improve the lifting surface area of wind-force, the impetus of wind-force is utilized to realize automatically cleaning to greatest extent, thus reduce flashover occur probability, the utility model also have simple and reasonable, cost is lower, useful life is longer, and can improve filthy icing composite insulator interchange flashover voltage advantage.
2, technical scheme
In order to solve the problem, the technical scheme that the utility model adopts is as follows:
A kind of composite cross-arm insulator string being suitable for high altitude localities band clearing apparatus, comprise axis, equally spaced be located at described in axial umbrella disk, clearing apparatus and retainer ring, described clearing apparatus has 2-4 to overlap, and it comprises cleaning leaf and brush, described cleaning leaf is fan shape, described brush is arranged on the inner side of described cleaning leaf vertical edge, the outer rim shape of described brush matches with the surface of the umbrella disk of all sub-umbrella of insulator string, described retainer ring is located at the two ends up and down of described insulator, and the outer surface of described retainer ring has the uniform bayonet socket of single circumference, and be enclosed within the axis of the umbrella disk up and down of the sub-umbrella of insulator, the equal horizontal-extending of upper and lower side of described cleaning leaf is provided with a chuck, described chuck is stuck on the bayonet socket on the retainer ring being enclosed within described umbrella disk top and the bottom respectively.
Preferably, described clearing apparatus has 3 covers.
Preferably, described clearing apparatus and retainer ring are made by silicon rubber.
3, beneficial effect
Compared to prior art, the beneficial effects of the utility model are:
The umbrella disk profile design of cleaning leaf according to the sub-umbrella of stacked insulator being applicable to the clearing apparatus of the composite cross-arm insulator string of high altitude localities of the present utility model, to enable brush by clean for insulator surface cleaning, thus reduce the probability of flashover generation.
Inside cleaning leaf, brush is installed, the outer rim shape of brush matches with the surface of the umbrella disk of all sub-umbrella of insulator string, and be connected with central axis by retainer ring, and clean the thin-wall construction that leaf is fan shape, improve the lifting surface area of wind-force, the impetus of wind-force is utilized to realize automatically cleaning to greatest extent, thus the rotation that cleaning leaf can be made in high altitude localities more smooth.And the utility model also has simple and reasonable, dependable performance, manufacture is simple, cost is lower, and useful life is longer, and effectively can improve the advantage that filthy icing composite insulator exchanges flashover voltage.Therefore, there is very large Social and economic benef@.
