Power connection fitting for high-voltage overhead transmission line

Abstract

The invention relates to a power connection fitting for a high-voltage overhead transmission line, which comprises fixing frames, connecting frames and a connecting device, and the fixing frames are of annular structures, the connecting frames are uniformly mounted on the outer sides of the fixing frames, the connecting frames are of cylindrical hollow structures, and the connecting device is mounted between the outer sides of the connecting frames. The problems are solved that when an existing connection fitting is used, the connection effect is poor, use is inconvenient, the extension lengthof an adjusting rod cannot be effectively adjusted, then power transmission lines with different intervals cannot be used, the adaptation effect of the connection fitting is poor, and when the existing connection fitting is used, the connection fitting is poor in buffering effect and cannot effectively buffer vibration generated by a wire, so that a power transmission line is prone to generate alarge damping effect, and the conveying effect of the power transmission line is affected.

Description

technical field [0001] The invention relates to the technical field of electric power fittings, in particular to a power connecting fitting for high-voltage overhead transmission lines. Background technique [0002] The spacer bar refers to the fittings installed on the split wires to fix the distance between the split wires to prevent the wires from whipping each other, suppress the breeze vibration and the vibration of the sub-gap. Two, four or more split wires are used, in order to ensure that the distance between the split wire bundles remains unchanged to meet the electrical performance, reduce the surface potential gradient, and in the case of a short circuit, the electromagnetic force will not be generated between the wire bundles, causing mutual attraction and collision. Or though cause the momentary attraction collision, promptly can get back to normal state after the accident is eliminated, thereby install spacer bar at a certain distance in the span.

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem of poor connection effect and inconvenient use of the existing connecting fittings, and the inability to effectively adjust the extension length of the adjusting rod, and thus the inability to use transmission lines with different spacings, resulting in the failure of the connecting fittings. The adaptation effect is poor, and when the existing connecting fittings are used, the buffering effect of the connecting fittings is poor, and the vibration generated by the wire cannot be effectively buffered, resulting in a large damping effect on the transmission line, which affects the transmission of the transmission line Effects and other problems
