  • THE JET NEUTRAL INJECTION 160 KV TRANSMISSION LINES, THE ASSOCIATED SNUBBERS AND THE SF6 TOWER FOR THE TERMINATION OF THE TRANSMISSION LINES HOUSING OF THE SNUBBERS AND VOLTAGE BREAKS

Abstract

The JET neutral injection system consists of 16 injectors for operation on the torus plus 2 injectors in the Testbed. The 16 injectors are divided into two groups of 8. One feature of JET is that it is designed for active operation with Tritium. As a consequence, no components requiring regular maintenance can be installed in the active zone. Therefore, the neutral injector power supplies are installed in an adjacent building. A special cable (called transmission line) was constructed to connect the power supplies to the neutral injectors. Due to the length of these transmission lines, snubbers are necessary to limit the short circuit energy and the maximum current in the injector in case of breakdown. A special vessel (called the SF6 Tower) was constructed to house the snubbers, the high voltage breaks in the cooling water circuits, etc.
