Description

Wind-deflection-prevention jumper composite insulator combination

Technical Field

The utility model relates to the technical field of composite insulators, in particular to a wind deflection prevention jumper wire composite insulator combination.

Background

Under severe weather conditions such as strong wind and storm, a drainage jumper wire on a corner tension-resistant iron tower in an overhead high-voltage transmission line cannot ensure the safe distance between the jumper wire and a tower body, is extremely prone to wind deflection flashover faults, and seriously affects the safe operation of the system. At present, a rod-shaped composite insulator is often used for fixing the hard jumper wire, so that the hard jumper wire is prevented from swinging in strong wind.

The utility model discloses a wind deflection prevention jumper composite insulator with an announcement number of CN 203055553U. Mainly solves the technical problems that the existing composite insulator has weak wind deflection inhibiting capability, poor wind deflection swinging bearing capability and lower stretching and bending load bearing capability. The insulating core rod is contained in the sheath, and the supporting component and the fixing component are respectively connected with the two ends of the sheath and form clamping and press fit through the compression rings. The special rigid-flexible characteristic of the epoxy glass fiber core rod and the connection mode of the hardware component are utilized, so that the large moment generated by instantaneous windage is reduced, the windage deflection is damped and inhibited, windage deflection swinging is borne, the windage deflection wire jumper composite insulator is ensured to bear tensile and bending loads, and the windage deflection wire jumper flashover phenomenon is avoided.

The utility model has the advantages that one end of the insulator is rigidly connected with the corresponding part of the electric iron tower, and the other end of the insulator is flexibly connected with the wire fitting, so that the connection stability of the insulator can be ensured, the whole insulator only generates slight windage under the condition of strong wind, the insulation distance between the wire and the ground is ensured, the occurrence of the wind windage discharge gate falling accident is effectively prevented, the insulator is applicable to the hard jumper of a high-voltage line, and the safety of a power transmission line can be ensured.

In the two technical schemes, a single bar-shaped composite insulator is adopted for hanging and fixedly installing a high-voltage circuit hard jumper, however, because the strip bar-shaped structure of the single composite insulator is poor in bending resistance, the situation that bending deformation and even fracture of a joint of a hardware fitting and a glass fiber core rod easily occur in strong wind influences the safe operation of electric facilities.
