Universal lead grounding device for power transmission line

Abstract

The invention discloses a transmission line universal wire grounding device, which comprises an angle steel fixing seat, a clamping mechanism and a mounting mechanism, one end of the angle steel fixing seat is connected with the mounting mechanism, the other end of the angle steel fixing seat is fixedly connected with a fixing sleeve, and one end of the fixing sleeve is provided with the clamping mechanism. A wire is clamped and fixedly connected to the clamping mechanism, and a limiting mechanism is mounted on the clamping mechanism; according to the wire clamping device, a wire penetrates through the position between the first clamping part and the second clamping part, the lead screw is rotated, a rope can be wound on the lead screw, one end of the rope drives one end of a fixing ring to move upwards, and therefore the first clamping part and the second clamping part can be engaged with each other, the wire is limited and fixed, and the wire is clamped by rotating a first fixing plate; and the limiting teeth on the first fixing plate can be inserted into the limiting grooves, so that one side of the wire can be limited and fixed, and the potential safety hazard that the wire is not firmly contacted and is easy to fall off due to collision or pulling is avoided.

Description

technical field [0001] The invention relates to the technical field of wire grounding devices, in particular to a general-purpose wire grounding device for power transmission lines. Background technique [0002] When carrying out power outage maintenance operations for ultra-(extra) high-voltage transmission lines, installing and disassembling the grounding wire is a technical measure to ensure safety. At present, the short-circuit grounding wire clips used for AC and DC lines with a voltage level of 500kV and above in China are mostly impact-type duckbill-shaped wires. Clips and tongue-type compression clamps, due to the inherent structural and principle defects of this type of clamps, there are potential safety hazards that the clamps and wires may not be in firm contact, and may fall off easily by impact or pulling. In addition, the grounding wire or Personal security lines must use bolt fastening or other types of clamps with locking functions, and impact duckbill clamps...

[0002] When carrying out power outage maintenance operations for ultra-(extra) high-voltage transmission lines, installing and disassembling the grounding wire is a technical measure to ensure safety. At present, the short-circuit grounding wire clips used for AC and DC lines with a voltage level of 500kV and above in China are mostly impact-type duckbill-shaped wires. Clips and tongue-type compression clamps, due to the inherent structural and principle defects of this type of clamps, there are potential safety hazards that the clamps and wires may not be in firm contact, and may fall off easily by impact or pulling. In addition, the grounding wire or Personal security lines must use bolt fastening or other types of clamps with locking functions, and impact duckbill clamps and tongue-type compression clamps will be completely discontinued before December 31, 2017.
