Description

Anti-torsion rotation type spacer

Technical Field

The invention relates to the technical field of power equipment, in particular to an anti-torsion rotation type spacer.

Background

The spacer is a hardware fitting which is installed on the split conductors and fixes the space between the split conductors to prevent the conductors from mutually whipping and inhibit breeze vibration and subspan vibration, and the main requirements for the spacer are that the wire clamp has enough grip strength, the wire clamp is not allowed to loosen in long-term operation, and the overall strength of the spacer can resist the centripetal force of the split conductors when a circuit is short-circuited and fatigue under long-term vibration. The spacer can be divided into two categories of damping and rigidity from the use performance, the wear-resistant rubber pad is embedded in the movable part of the damping spacer, and the damping of the rubber pad is utilized to consume the vibration energy of the lead, so that the damping effect is generated on the vibration of the lead. The rigid spacer without the rubber pad is generally used in an area difficult to generate vibration or used for a jumper spacer, namely a damping spacer and a non-damping spacer, due to poor vibration absorption performance. The damping type spacer is characterized in that: rubber is used as damping material at the movable joint of the spacer to consume the vibration energy of the lead and generate damping effect on the vibration of the lead. Therefore, the spacer is suitable for various regions. However, in view of the economical efficiency of power transmission lines, this type of spacer is focused on lines for areas where the wires are susceptible to vibration. The non-damping spacer has poor shock absorption, and can be applied to lines in areas difficult to generate vibration or used as jumper spacers.

The existing spacer is easy to twist together when meeting strong wind, needs manual adjustment of workers, wastes time and labor, and increases labor cost.
