Cause analysis on cold bend orange peel shape defect of copper bar for electric transducer generator;

Substation busbar eddy current field analysis based on time -stepping finite element method;

The busbars in an IGCT-based high power three-level converter are studied.

By means of the application of multi-layer busbars to reduce the distributed inductance in the main bus,and the proper design of snubber circuits to moderate the switching locus,the switching-off voltage pulse will be restrained,so that the switching devices could run in a reliable operation ranges.

sprayed Cr coating by A plasma on copper busbar was remelted using a 5kW CO2 laser.

Copper busbars are important in high-low electric apparatus,they have both effect on installation and electric conduction,therefore,the processing technic of copper busbar is important especially.

By simplifying the geometry model of the copper bus bar continuous extrusion process,based on a new metal forming simulation package,MSC.

In order to investigate the extrusion capacity of extending continuous extrusion for copper bus bar,the extending deformation zone of billet was divided into two separated sub-zones, and the analytic equations about the unit force on the chamber inlet were established by analyzing them respectively with Upper Bound Method.

In order to investigate the relationships among the expanded extrusion capacity of continuous extrusion for copper bus bar and the billet diameter,friction condition and structure parameters of chamber and die,the expanded deformation zone of billet was divided into two sub-zones according to the deformation characteristics of billet in the expanded die chamber.

3D-FEM mathematical simulation of CONFORM extending-forming process for copper busbar;

The continuous extrusion extending forming process for copper busbar was simulated by FEM software DEFORM3D.
