Description
Technical Field
The utility model relates to the technical field of spacers, in particular to a novel flexible and rotatable TJ spacer.
Background
With the rapid development of power grids, the lengths of ultra-high and extra-high voltage transmission lines are increased year by year. 500kV ultrahigh voltage transmission line usually adopts the quadripartion wire, and strain insulator tower needs to connect with the quadripartion wire jumper form, for making the quadripartion wire jumper keep certain split interval, goes up the side sub-wire and links to each other with the yoke plate through strain insulator clamp, adjusting plate, extension rod, and the side sub-wire links to each other with the yoke plate through strain insulator clamp, adjusting plate, extension rod, and so, goes up the side sub-wire jumper inevitably and contact or collide with the lower side extension rod. The influence of the weather environment on the overhead transmission line is obvious, and the phenomena of vibration and swing of the wires and the jumper wires under the condition of strong wind cause the abrasion of the jumper wire of the upper sub-wire and the extension rod of the lower sub-wire to be aggravated, and the breakage of the sub-wire is caused in serious conditions, so that the line fault is caused.
In order to ensure the stable operation of the overhead transmission line and avoid the abrasion fault of the sub-conductor jumper, a common TJ-type jumper spacer is usually arranged between the upper side sub-conductor jumper and the lower side extension rod. Because the installation position of the TJ-shaped jumper spacer is very short (generally less than 1m) away from the strain clamp drainage plate, a rigid connecting rod structure is formed between the extension rod and the TJ spacer and the drainage plate jumper and between the extension rod and the strain clamp drainage plate, and when the two connected sub-wires vibrate due to breeze, the rigid connecting rod affects the two sub-wires and the strain clamp crimping pipe.
At present, the TJ spacer applied in the line design and model selection is a rigid structure, the breeze vibration energy of the upper sub-conductor and the lower sub-conductor is acted on the TJ spacer, and the TJ spacer is frequently separated at a wire clamp or a middle bolt connection part under the long-time wind vibration action. In addition, the drainage plate of the strain clamp of the upper side wire not only bears the self weight and wind load of the jumper wire, but also bears and transmits the vibration of the upper sub-wire and the lower sub-wire, the rigid TJ spacer can not reduce the vibration energy, if the upper sub-wire and the lower sub-wire generate different-frequency and lasting breeze vibration, the drainage plate can generate fatigue damage or even cause fracture, and the safe and stable operation of the transmission line is seriously influenced.
Therefore, aiming at the problems, a novel flexible and rotatable TJ spacer is provided.
