E7-25 capacitive energy store for power supplying loads of electro-discharge loads

Summary form only given. A capacitive energy store is described for supplying experiments with electro-discharge launchers and other loads. The designed stored energy is 17.2 MJ, maximum voltage is 25 kV, discharge current range is 10 MA and the frequency of the discharge current oscillations in short circuit is 8 kHz. The store was built on a modular principle. It contains 23 modules, all of which consist of 8 cells. Every cell has capacitors of 94 kJ stored energy and vacuum triggered vacuum switches. Control and synchronization systems of the storage provide remote operation by every module and nonsimultaneous programmed discharge, where triggered switches in cells are switched-on in definite time. The first phase of the store was put in operation with 9 MJ of stored energy (12 modules) and was tested with a 10 MA discharge current.
