Double-split wire anti-galling spacer soft connection device

Abstract

The invention discloses a double-split wire anti-galling spacer flexible connection device, which comprises an upper sub-conductor clamp for connecting an upper sub-conductor and a lower sub-conductor clamp for connecting a lower sub-conductor; an upper sub-conductor clamp and an upper end sleeve The top of the tube is connected, and the bottom of the upper sleeve is connected with a bottom cover with a bottom cover opening; the lower wire clamp is connected with the lower sleeve; the bottom of the upper sleeve passes through the top of the lower sleeve and embedded inside the lower sleeve; the spring The bottom surface of the fixed column is fixed on the inner bottom surface of the lower sleeve, and the top of the spring fixed column passes through the opening of the bottom cover and enters the inside of the upper sleeve; the top of the spring fixed column is connected with a top cover; an upper end is provided between the top cover and the bottom cover Spring; a lower end spring is arranged between the bottom cover and the inner bottom surface of the lower end casing; the present invention can reduce the stress on the upper wire and the lower wire clamp at the wire clamp through the buffering effect of the spring and the universal rotating shaft, thereby greatly reducing the stress on the wire The risk of broken stocks and disconnected lines.

Description

technical field [0001] The invention relates to the field of anti-galling of high-voltage transmission lines, and more specifically relates to a soft connection device for anti-galling spacers of double-split wires. Background technique [0002] At present, the anti-galling spacer bar installed on the double-split conductor of the transmission line adopts the method of vertically double-arranged suspension clamps between the sub-conductors. When the conductor vibrates, the waveform bends up and down along the conductor line, and there are differences in size at each point The dynamic bending stress, especially at the suspension clamp, because the clamp is restricted by the fixed connecting plate, the dynamic bending stress in the clamp is the largest and lasts the longest, which will cause the wire to bend repeatedly, which will easily lead to the wire being clamped in the clamp. Internal fatigue broken strands, broken wires, broken strands, and broken wires are in the suspe...

Problems solved by technology

like figure 1 As shown, the connection between the upper sub-conductor and the lower sub-conductor (generally with an average distance of 400mm) in the prior art device is fixed, and it is easy to generate a large stress on the conductor due to the galloping between the upper sub-conductor and the lower sub-conductor, thereby forming damage
