Preferably, described full skirt group is provided with two.
Preferably, the described big a diameter of 205mm of cluster parachute group, the middle a diameter of 187mm of cluster parachute group, the little a diameter of 157mm of cluster parachute group, sheath diameter is 71mm, and big cluster parachute group is 98mm with the spacing of middle cluster parachute group, middle cluster parachute group is 33mm with the spacing of little cluster parachute group, and two isometrical little cluster parachute group's spacing are 32.5mm.
Preferably, described upper flange, lower flange are coaxial with plug employing 360 ° to be crimped, and described plug is interior insulating glass fibers leading-drawing rod.
Preferably, group manner is climbed in described lower flange and increasing: there is indent step lower flange processing bottom, above-mentioned increasing is climbed group and is machined with inwardly protruding and relative projection, and lower flange cooperatively forms self-locking connection structure by indent step with projection conflict, and this lower flange is arranged at sheath the inner.
Preferably, described lower flange and increasing are climbed contact surface between group and are provided with reinforcement.
Preferably, described increasing is climbed the increasing that group is tilting structure and is climbed group.
Preferably, described full skirt group uses the design of dripping eaves structure.
A kind of EMUs that this utility model obtains are with high and cold anti-blown sand post composite insulators, compared with similar products, it is big that the high and cold anti-blown sand pillar composite silicone rubber insulator of a new generation has creep distance, its antifouling work ability is strong, has excellent hydrophobicity and hydrophobicity migration performance so that filth is evenly distributed on the insulator, under the conditions of identical filth, its flashover voltage is than improving more than 30%, power frequency withstanding voltage improves 20%, and creep age distance improves 20%, and electric clearance improves 25%.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: group 8, interior rank 11, projection 12, projection 13, indent step 14 are climbed in upper flange 1, big cluster parachute 2, little cluster parachute 3, middle cluster parachute 4, sheath 6, plug 5, lower flange 7, increasing.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Embodiment:
As it is shown in figure 1, a kind of EMUs that the present embodiment provides are with high and cold anti-blown sand post composite insulators, including upper flange 1, big cluster parachute 2, little cluster parachute 3, middle cluster parachute 4, sheath 6, plug 5, lower flange 7.Described plug 5 is placed in above-mentioned sheath 6 inner chamber, plug 5 two ends and upper and lower Flange joint, interior rank 11 it are provided with on the inwall at sheath 6 both ends, protruding 12 it are provided with on these interior rank 11, the step with inner groovy it is provided with on upper flange, lower flange, this step fastens with interior rank, sheath ends is provided with the increasing fastened with lower flange and climbs group 8, big cluster parachute 2, several little cluster parachutes 3 and middle cluster parachute 4 form full skirt group, full skirt group described in the utility model is provided with two, and described big cluster parachute 2, little cluster parachute 3 and middle cluster parachute 4 is sequentially arranged at intervals from left to right.
Wherein, this utility model uses product post composite insulators structure height to be 480mm, the described big a diameter of 205mm of cluster parachute 2, the middle a diameter of 187mm of cluster parachute 3, the little a diameter of 157mm of cluster parachute 4, the a diameter of 71mm of sheath 6, big cluster parachute 2 is 98mm with the spacing of middle cluster parachute 4, and middle cluster parachute 4 is 33mm with the spacing of little cluster parachute 3, two isometrical little cluster parachute 3 spacing are 32.5mm, increasing and do not limit length here, such scheme is one of which scheme, and concrete diameter length can be according to the market demand fixed.First gamp is mined massively and is designed with maximum gauge, increases product electric clearance 10%, effectively prevents in high and cold weather area, occur icing along occur between umbrella and umbrella ice flash as.Each cluster parachute group edge large and small, middle uses dripping eaves design, designs structure for anti-fouling type, to increase the tearing toughness of silicon rubber umbrella skirt, and effectively at the vile weather such as high and cold, dust storm, rainwater, tears, bridges phenomenon, thus prevent flashover.
Further, described upper flange 1, lower flange 7 use 360 ° coaxial to crimp with plug 5, and described plug 5 is interior insulating glass fibers leading-drawing rod.And upper lower flange and interior two pieces of pins of insulating glass fibers pulling bastinade, make product have the mechanical performances such as good bending resistance, resistance to compression, antitorque, tension.
Further, group 8 manner is climbed in described lower flange 7 and increasing: there is indent step 14 lower flange processing bottom, above-mentioned increasing is climbed group and is machined with inwardly protruding and relative projection 13, and lower flange is conflicted with projection 13 to coordinate by indent step 14 and made lower flange be arranged at sheath the inner.Increasing that climbing mines massively designs with tilting, by height on earth, at heavy rain weather, rainwater can climb group towards dirty along increasing, effectively prevents base seeping phenomenon.Increasing is climbed group and is used three road 5mm silicone rubber reinforcements to support with lower flange contact surface, prevents creeping-increasing skirt from subsiding.
5 millimeters of indent steps 14 of bottom processing of lower flange 7, climb increasing group projection 13 and buckle in the concavo-concave groove of lower flange, use self-locking connection structure, and cluster parachute wraps the side of overall lower flange, is effectively prevented between umbrella, along face bridge joint, flashover fault occurs.
For this utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its framework form can be flexible and changeable; simply make some simple deduction or replace, the scope of patent protection that the claims that all should be considered as belonging to be submitted to by this utility model determine.
