Abstract
The utility model relates to an anti-windage jumper wire composite insulator, mainly solving the technical problems that conventional composite insulators are weak in windage inhibition capability, poor in windage swinging bearing capacity, and relatively weak in stretch proofing and bend loading abilities. The anti-windage jumper wire composite insulator comprises an insulating core rod, umbrella skirts, and a sheath. The umbrella skirts are located on the outer periphery of the sheath. The two ends of the sheath are respectively provided with a bearing assembly and a fixing assembly. The anti-windage jumper wire composite insulator is characterized in that the insulating core rod made of epoxy glass fibers is accommodated in the sheath, and the bearing assembly and the fixing assembly are respectively connected with the two ends of the sheath and are in compression fit with the two ends of the sheath through pressing rings. By virtue of utilizing the hard and soft characteristics specific to the epoxy glass fiber core rod as well as the connecting mode of metal fitting assemblies, the large torque generated by instantaneous windage is decreased; the damping and windage inhibition capacities are improved; the windage swinging can be borne; the stretch proofing and bend loading abilities of the anti-windage jumper wire composite insulator are guaranteed; and thus, the phenomenon of windage jumper wire flashover is prevented.
Description
Technical field
The utility model relates to a kind of insulator, refers in particular to a kind of anti-windage yaw wire jumper composite insulator.
Background technology
Windage yaw flashover phenomenon very easily takes place in the drainage wire jumper on the aerial high-voltage power transmission lines such as 110 kV, 220 kV under bad weather conditions such as strong wind, storm wind, particularly can not guarantee that as big (outward) corner strain insulator iron tower wire jumper wire jumper is apart from the safe distance of body of the tower under bad weather conditions such as strong wind, easily cause windage yaw bounce flash fault, have a strong impact on system's operation.Power department has also been taked as installing weight additional, changing measures such as serial type before this, and effect is unsatisfactory, suppresses a little less than the windage yaw ability, and it is poor to bear the windage yaw swing, bears stretch-proof and the bend loading ability is lower.
Summary of the invention
In order to overcome deficiency and the defective in the background technology, the utility model provides a kind of anti-windage yaw wire jumper composite insulator, solve existing composite insulator and exist and suppress a little less than the windage yaw ability, it is poor to bear the windage yaw swing, bears stretch-proof and the lower technical problem of bend loading ability.
The technical solution of the utility model is: a kind of anti-windage yaw wire jumper composite insulator, comprise insulation mandrel, full skirt and sheath, described full skirt is positioned at the sheath periphery, the two ends of described sheath are respectively equipped with bearing assembly and fixation kit, the insulation mandrel of being made by epoxy glass fiber is placed in the sheath, and described bearing assembly, fixation kit are connected with the two ends of sheath respectively and constitute the card interference fit by pressure ring.
Described bearing assembly comprises T-shape bearing, bolt, and described T-shape bearing comprises horizontal component and vertical part, and described vertical part plugs with sheath, and described bolt is installed on the two ends of horizontal component.
Described pressure ring comprises snap ring, support, and described snap ring is provided with deep-slotted chip breaker, and the end of described support is placed in the described deep-slotted chip breaker.
The beneficial effects of the utility model: the connected mode of utilizing the distinctive hard and soft characteristic of epoxy glass fiber plug and armour clamp assembly, reduce the big moment that instantaneous windage yaw produces, damping, inhibition windage yaw ability, bear the windage yaw swing, guaranteed that anti-windage yaw wire jumper composite insulator bears stretch-proof and bend loading, thereby avoided windage yaw wire jumper flashover phenomenon.
