Twin Type Double Conductor Bus-Bar Spacer Damper

Description:
Tubular busbar is one of the commonly used equipment in power transmission and transformation system. It has good current-carrying performance and reliable mechanical connection performance. It is often used between transmission wires and transformers and in power equipment, and plays the role of connecting conductors. Its stable operation plays a vital role in the reliable operation of power transmission and transformation systems. The duralumin round tube busbar, which is widely used in actual engineering, has the advantages of high rated operating voltage and small rated operating current, and its hollow structure and smooth surface are very conducive to increasing the corona inception voltage.

The bus-bar spacer damper is a special type of spacer. Its main function is to limit the relative movement between the multi-split tube bus bars, prevent the tube bus bars from colliding with each other, and maintain the geometry of the bus bars to meet the requirements of reducing the surface potential gradient and Reduce the occurrence of corona effect and other electrical properties, and provide reliable mechanical and electrical performance guarantee for the circuit. However, there has been no good control method for the corona discharge of the high-voltage split tube busbar spacer, and it is difficult to accurately obtain the electric field intensity on the surface of the tube busbar spacer damper to ensure that the electric field intensity on the spacer surface does not exceed the corona inception field intensity.
