Description

Double frame damping type spacer

Technical field

The present invention relates to a double frame damping type spacer.

Background technique

Long-distance, high-capacity ultra-high voltage transmission lines use two, four or more split conductors per phase conductor. At present, 220KV and 330KV transmission lines use two split conductors, 500KV transmission lines use three-split and four-split conductors, and ultra-high voltage transmission lines with voltages higher than 500KV use six-split and more split conductors. In order to ensure that the split wire harness spacing remains unchanged to meet the electrical performance, reduce the surface potential gradient, and in the case of a short circuit, no electromagnetic force is generated between the wire harnesses, causing mutual attraction collision, or causing an instantaneous attraction collision, but after the accident is eliminated That is, it can be restored to the normal state, and thus the spacer bar is installed at a certain distance in the span. The installation spacer can also suppress the oscillation of the secondary gear and the breeze vibration.

The working characteristics of the spacers can be roughly divided into two types, namely, a damping type spacer and an undamped type spacer. The damping type spacer is characterized in that rubber is used as a damping material at the movable joint of the spacer to consume the vibration energy of the wire, which dampens the vibration of the wire.

The existing damping type spacer generally has four or eight mounting holes for clamping the rubber column on the frame main body and the collet main body. These rubber columns constitute a damping system for consuming the vibration energy of the wire. Damping the vibration of the wire. However, the damper type spacer rod for mounting the rubber column has the following disadvantages: First, the rubber column is troublesome to install, and the position of the rubber column needs to be constantly adjusted to ensure that all the rubber columns are installed in place, and the requirements for the installer are relatively high; In the high-altitude long-distance transportation, a light-weight damping spacer is required. However, the damping type spacer of this structure is relatively heavy and is not suitable for long-distance transportation at high altitude.
