Windbreak wire clamp

Abstract

The invention provides a windbreak wire clamp comprising a wire clamp body. A wire clamp pressing tube is arranged at the wire clamp body and has a hollow-out part; a connecting segment is arranged at the tail end of the wire clamp pressing tube, wherein the wall thickness of the connecting segment is larger than that of the rest part of the wire clamp pressing tube; a spring is fixed at the inner wall of the connecting segment; and a lead passes through the spring and is pressed in the hollow-out part of the wire clamp pressing tube. According to the wire clamp, the spring in the wire clamp pressing tube can be fixed to prevent oscillating of the lead; and the bending force with the stress length less than 10cm between the oscillating lead and the static wire clamp is dispersed to the whole spring length range from 40 to 60 cm by the spring, so that the bending wearing of the tail end of the lead can be reduced. On the basis of the structure, the windbreak wire clamp can be installed at different types of overhead transmission towers and substation equipment conveniently.

Description

technical field [0001] The invention relates to the technical field of power transmission and substation safety, in particular to a wire clamp for windproof equipment. Background technique [0002] China has a vast territory and various resources are unevenly distributed. It is obviously impossible to build wind power plants, thermal power plants, hydropower plants, and nuclear power plants separately in various places. Therefore, long-distance power transmission is required. At present, all countries transmit and distribute electric energy through high-voltage transmission lines and substations. [0003] Due to the wide distribution of transmission lines and substations, wind damage is serious in many areas. Wind-induced wire swings and wire breakage have always been a major problem in the power system. The lead wires of electrical equipment often swing under the action of the wind, and the clamps connecting the wires are generally fixed. The contact parts between the wire...

Problems solved by technology

[0003] Due to the wide distribution of transmission lines and substations, wind damage is serious in many areas. Wind-induced wire swings and wire breakage have always been a major problem in the power system. The lead wires of electrical equipment often swing under the action of the wind, and the clamps connecting the wires are generally fixed. The contact parts between the wires and the clamps are often bent, resulting in broken strands or even broken wires.

In the prior art, an anti-vibration hammer is installed on the transmission line to prevent the wind deflection of the wire from galloping, but the effect of preventing the wire from swinging is not good
