A fast circuit breaker for 105A current

  • 1. Paris-11 Univ., 91 - Orsay (France)

Description

A fast circuit breaker operated by an electromagnetic command has been realized. It can open very high currents in times in order of a few microseconds. By means of electromagnetic forces, a conductor is sent against rods and thus cut. The current is then transferred onto a fuse placed in parallel. The explosion of the fuse opens the circuit. A simplified set up has permitted to test some performances of the switch. A 240kA current has been opened in 6μs and a 5kV peak voltage simultaneously generated (half-width : 3μs). The transfer of a 130kA current has been realized in a time as small as 2μs
