Description

An easy-to-install spacer bar

technical field

The utility model relates to the technical field of high-voltage transmission, in particular to an easy-to-install spacer bar.

Background technique

Two, four or more split conductors are used for each phase conductor of long-distance and large-capacity EHV transmission lines. 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 distance between the split wire harnesses remains unchanged to meet the electrical performance, reduce the surface potential gradient, and in the case of a short circuit, the electromagnetic force will not be generated between the wire harnesses, causing mutual attraction and collision, or even if the instantaneous attraction collision is caused, but after the accident is eliminated Promptly can return to normal state, thereby spacer rods are installed at a certain distance in the span. The installation of spacer rods can also play a certain role in restraining the vibration of the secondary span and the vibration of the breeze. According to the working characteristics of the spacer rods, they can be roughly divided into two categories, namely damping type spacer rods and non-damping type spacer rods. The characteristic of the damping type spacer is that rubber is used as the damping material at the movable joint of the spacer to consume the vibration energy of the wire and produce a damping effect on the vibration of the wire. Therefore, this type of spacer is suitable for all regions. However, considering the economy of power transmission lines, this type of spacer is mainly used for lines in areas where conductors are prone to vibration. The non-damping spacer has poor shock absorption and can be applied to lines in areas where vibration is not easy to occur or used as a jumper spacer. The installation of existing spacers is troublesome, which brings inconvenience to subsequent replacement and maintenance.
