A coupled model of current conduction and static magnetic field is proposed, according to three dimensional (3D) axial magnetic fields (AMF) of two and three segments coil-type contact for a 72.5 kV/31.5 kA vacuum interrupter (VI). And the distributions of current density and electric potential are obtained using finite element method (FEM). Moreover, the conductor resistance and the characteristics...
Controlled switching has been used extensively throughout the whole world for shunt capacitor banks. By precisely controlling where on the voltage waveform the contacts touch, it is possible to greatly reduce the magnitudes of the switching electrical transients. This paper presents the basic principle and the software algorithms of controlled switching for three-phase shunt capacitor banks with ungrounded...
Acyl-CoA binding protein (ACBP) maintains a pool of fatty acyl-CoA molecules in the cell and plays a role in fatty acid metabolism. The biochemical properties of Plasmodium falciparum ACBP are described together with the 2.0 A resolution crystal structures of a P. falciparum ACBP-acyl-CoA complex and of bovine ACBP in two crystal forms. Overall, the bovine ACBP crystal structures are similar to the...
