Detailed analysis and physical design of a 254 KV, 600 KW continuous duty pulse transformer

The detailed engineering analysis and design for a 254 kV, 600 kW average power continuous duty pulse transformer was completed at the Westinghouse Science and Technology Center (STC). The transformer will be a part of the Sandia National Laboratories´ (SNL) Repetitive High Energy Pulse Power (RHEPP) system. The design effort is part of a joint project between SNL and Westinghouse STC. It is a unique collaborative arrangement in the W-STC is providing the design details to SNL and they will be responsible for the manufacture, installation, installation, and testing of he device. The transformer is designed to take a 14 kV input pulse and step it up to 254 kV. It will operate continuously at 120 pulses per second with a pulse width of about 115 /spl mu/-seconds. The analytical methos used in the design process are described. This includes a description of the analytical processes used to calculate the important electrical, thermal and insulation system parameters. The design configuration is presented showing the winding arrangement, core dimensions, and physical layout of the transformer.
