Description

A new flexible damping type TJ spacer for 500kV AC-DC transmission line

technical field

The utility model relates to a protective fitting for an ultra-high voltage AC-DC transmission line, in particular to a novel flexible damping type TJ spacer rod for a 500kV AC-DC transmission line, belonging to the technical field of ultra-high voltage AC-DC transmission.

Background technique

With the development of science and technology, ultra-high voltage power transmission technology is more and more widely used in people's daily life. Since the upper two sub-conductors of the four-split jumper conductors of the 500kV AC-DC transmission line are connected to the upper extension rods, they will touch the lower two sub-conductors or extension rods. When the conductors or jumpers swing due to ice and strong winds in winter Sometimes the wear of the wire will occur, and in severe cases, the sub-wire will be worn off. Therefore, in order to ensure the safe operation of the transmission line, a jumper ordinary TJ type spacer is often installed between the jumper on the tension tower and the extension rod. The jumper drain line equipment clamp crimping tube port is very close to the ordinary TJ type spacer bar, and the length of the drain line between the two is about 80mm to 100mm. Because the length of this section of wire is very short, the extension rod-drainage terminal board-equipment clamp -Short section conductors-Ordinary TJ type spacers are directly connected by bolts or crimping to form a rigid "integral" structure, which acts as a "connecting rod", connecting the upper tension clamp and the lower The extension rod is connected as one. When the two connected sub-conductors vibrate, they interact with each other through this "connecting rod", so that the up and down can be dragged and linked to each other, and they are on this rigid "connecting rod".

However, there are some deficiencies in the TJ-type spacers currently on the market. The upper sub-wire drainage terminal board of the traditional TJ-type spacer not only bears the self-gravity of the jumper and the swing force caused by the wind, but also bears and transmits the upper and lower parts at the same time. The vibration force of the two sub-conductors is the weakest link in the "connecting rod" structure. If there are different amplitudes, different frequencies, and long-term vibrations, the upper sub-wire drainage terminal board will be fatigued and broken, which will seriously affect the safe operation of the transmission line.

Therefore, in view of the above problems, a new flexible damping type TJ spacer for 500kV AC/DC transmission lines is proposed.
