The Contact Performance Analysis of Disconnecting Switch's Fixed Contact

In order to optimize and improve the GW6 disconnecting switch’s fixed contact existing structure, this paper, according to its conditions, sets up the analysis model by SolidWorks. In the integrated AWE exploiting environment, this paper does finite element analysis for its contact performance and temperature rising. To acquire the contact area and contact condition, it compares with four structures: original structure (no groove), the structure which has groove, the structure which has groove but not matching the ACSR, the structure with the cylinder ACSR. As a result, via changing the ACSR to the cylinder structure, the switch increases the area of contact surface, improves the contact condition, reduces the temperature rising. It solves the problem of overheat of conductive circuit, which makes the operation of the electric power system safe and reliable.
