Embodiment
As requested, will disclose the specific embodiment of the present invention here.Yet, should be understood that, disclosed execution mode is only exemplary of the present invention here, it can be presented as various forms.Therefore, here the detail disclosing is not considered to restrictive, and be only as the basis of claim and as for instructing those skilled in the art differently to apply representational basis of the present invention in any appropriate mode of reality, comprise employing disclosed various features in conjunction with the feature that may clearly not disclose here here.
As Figure 1-5, the insulator 200 of the present embodiment is porcelain post insulator, insulator 200 comprises the body of rod 21 and from the outward extending some full skirts 20 of the body of rod, the inner surface of the auxiliary umbrella cover 100 of the present embodiment forms host cavity 10, host cavity 10 is accommodated two full skirts 20, the external surface shape of insulator 200 corresponding positions that the shape of host cavity 10 is coated with this host cavity 10 is consistent, and host cavity 10 is coated into the full skirt of full wafer 20.Auxiliary umbrella cover 100 is provided with lengthening umbrella 11 away from the edge of insulator 200 axis, and lengthening umbrella 11 stretches out along circumferential outer radiation, can greatly increase like this creepage distance of insulator 200.The inner surface of auxiliary umbrella cover 100 is provided with projection 12, projection 12 makes the inner surface of auxiliary umbrella cover 100 and full skirt 20 surfaces produce gap 15, in gap 15, be filled with binding agent, by binding agent, will assist umbrella cover 100 to be bonded on insulator 200, and make can not be polluted between the two and cause the life-span of auxiliary umbrella cover 100 to be reduced.Projection 12, for bar shaped, is uniformly distributed in a circumferential direction, and binding agent is evenly distributed, and makes between auxiliary umbrella cover 100 and insulator 200 fixing more firm.Projection 12 was upwards interrupted in week, to prevent that intercepting binding agent is full of whole gap 15.Auxiliary umbrella cover 100 is provided with opening 13 on radially, for opening host cavity 10, full skirt 20 is included in host cavity 10.Opening 13 edges are provided with bond regions 14, and auxiliary umbrella cover 100 sticks on bond regions 14 by opening 13 bondings by scribbling the bonding strip of binding agent.The two ends of auxiliary umbrella cover 100 have respectively the sleeve part 16 being socketed on the body of rod 21, sleeve part 16 can effectively reduce the area that auxiliary umbrella cover 100 ends contact with insulator 200, reduce the area that needs the auxiliary umbrella cover of sealing 100 ends, make to fix between auxiliary umbrella cover 100 and insulator 200 more firm, be more difficultly subject to extraneous pollution.As shown in Figure 5, for four auxiliary umbrella covers 100 of the embodiment of the present invention are arranged on the schematic diagram on insulator 200, auxiliary umbrella cover 100 interval on insulator 200 arranges, and can effectively increase the creepage distance of insulator 200 and the ability that anti-soil dodges, anti-ice is dodged.
The auxiliary umbrella cover 100 of the present embodiment, is coated into full skirt 20 is whole, and the anti-soil that has improved insulator 200 surfaces dodges, anti-rain dodges and anti-ice is dodged ability.Lengthening umbrella 11 has increased the creepage distance on insulator 200 surfaces, has improved the insulation property of insulator 200.Auxiliary umbrella cover 100 will assist umbrella cover 100 to be fixed on insulator 200 by the binding agent in gap 15, prevent from entering pollutant between the two, the life-span of the auxiliary umbrella cover 100 of impact.The auxiliary umbrella cover 100 of the embodiment of the present invention can increase the anti-soil sudden strain of a muscle of insulator 200 in sum, anti-rain dodges and anti-ice is dodged ability, increases the creepage distance on insulator 200 surfaces, easy for installation, long service life.
Fig. 6 is that the auxiliary umbrella cover 300 of further embodiment of this invention is coated on the cutaway view on insulator 400, and the insulator 400 of the present embodiment comprises the body of rod 41 and from the outward extending some full skirts 40 of the body of rod 41.The auxiliary umbrella cover 300 of the present embodiment is accommodated two full skirts 40, comprises upper umbrella cover 37 and lower umbrella cover 38 that split arranges, and the position at the corresponding body of rod 41 between upper umbrella cover 37 and lower umbrella cover 38 connects.The auxiliary umbrella cover 300 of split setting is easy to processing, can from the manufacture of mould and the difficulty of manufacture process, effectively reduce the manufacturing cost of auxiliary umbrella cover 300.When mounted, split type auxiliary umbrella cover 300 is also convenient to be arranged on insulator 400.At upper umbrella cover 37, adopt stepped design with the position that lower umbrella cover 38 is connected, can effectively prevent that pollutant from entering between auxiliary umbrella cover 300 and insulator 400, increased the useful life of auxiliary umbrella cover 300.
Technology contents of the present invention and technical characterstic have disclosed as above; yet be appreciated that; under creative ideas of the present invention; those skilled in the art can make various changes and improve said structure and material; comprise here and to disclose separately or the combination of claimed technical characterictic, comprise significantly other combination of these features.These distortion and/or combination all fall in technical field involved in the present invention, and fall into the protection range of the claims in the present invention.
