Abstract
The utility model relates to a windage yaw preventing composite insulator, comprising an insulating mandril, and a silica gel umbrella cover connected to the outer wall of the insulating mandril in a manner of cup joint, wherein one end of the insulating mandril is connected with a movable coupling seat flexibly connected with corresponding electric power fittings or components, and the other end of the insulating mandril is connected with a fixed coupling seat rigidly connected with corresponding electric power fittings or components. One end of the windage yaw preventing composite insulator is rigidly connected with corresponding components of an electric power iron tower, the other end is flexibly connected with lead fittings, thereby ensuring self coupling firmness of the insulator, enabling the whole insulator to generate minimal windage yaw under the condition of strong wind, ensuring the insulating distance between lead and ground, effectively preventing occurrence of windage yaw discharging brake dropping accident, being suitable for high voltage line hard jumper wire, and ensuring safety of power transmission lines.
Description
Technical field: the utility model relates to the insulator that uses in a kind of high voltage overhead power circuit, particularly hard wire jumper insulator.
Background technology: extreme weathers such as strong wind can produce power network line and have a strong impact on, and are one of principal modes of high voltage overhead power circuit breaking by big wind-induced windage yaw flashover breaking phenomenon wherein.General composite insulator is in light weight, and it is that ball-and-socket is connected with the connected mode of electric power tower, and displacement is rotated easily, and the steadiness that self connects is not high, anti-windage yaw ability.Lead because tangent tower insulator string or strain tower wire jumper string easy angle of oscillation under wind effect are excessive, causes lead that tower body is discharged when waving with the wind, and phenomenons such as line tripping, lead electric arc burn, disconnected thigh, broken string take place.
Summary of the invention: to the deficiency of prior art, the utility model provides a kind of anti-windage yaw composite insulator of avoiding big wind-induced high voltage overhead power circuit breaking.
The utility model comprises insulation mandrel and is socketed in the silica gel umbrella cover of its outer wall, is connected with movable connection seat at an end of insulation mandrel, and it is with corresponding electric armour clamp or parts are flexible connects; The other end of insulation mandrel is connected with fixed connection seat, itself and corresponding electric armour clamp or parts rigid attachment.
One end of the utility model and the corresponding component of electric power tower are rigid attachment; The other end then connects with the lead gold utensil is flexible, both can guarantee the connection steadiness of insulator self, makes whole insulator that small windage yaw only takes place under the high wind situation again; Guaranteed that lead relatively and the insulation distance between the ground; Effectively prevent the generation of windage yaw discharge breaking accident,, can guarantee the safety of transmission line applicable to the hard wire jumper usefulness of high-tension line.
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Description of drawings: Fig. 1 is the main structure sketch map of embodiment.
Fig. 2 is the end face vertical view of fixed connection seat among Fig. 1.
Embodiment: as shown in Figure 1, the outer wall of insulation mandrel 1 is socketed with silica gel umbrella cover 4, is connected with movable connection seat 3 at an end of insulation mandrel 1, and it is with corresponding electric armour clamp or parts are flexible connects; The other end of insulation mandrel 1 is connected with fixed connection seat 2, itself and corresponding electric armour clamp or parts rigid attachment.7 flexible connections of gold utensil of general activity formula connection seat 3 and electrical lead 6, the corresponding component rigid attachment of 2 of fixed connection seats and electric power tower.
The movable connection seat 3 of present embodiment adopts ball cup; Fixed connection seat 2 adopts the cross-arm connection seat, and as shown in Figure 2, and fixed connection seat 2 is the end face slab structure; End face is provided with several through holes 5, and securing member passes corresponding through hole 5 and connects with the cross-arm parts of electric power tower.
In the reality, the insulation mandrel 1 general ECR high temperature that adopts is strengthened acidproof plug, has high-tensile and pliability is arranged.The both ends of insulation mandrel 1 connect then adopts coaxial constant pressure type crimping, the stress good dispersion, and steady quality is reliable.The silica gel umbrella cover 4 general sheath global formation technology of using guarantee that all creepage distances are effective under any weather and the filthy condition, improve the aerial self-cleaning pollution discharge capability of composite insulator.
