Abstract
The invention pertains to a DC current interruption system able to open a DC line with inductive behavior, comprising a primary mechanical breaker (S), a secondary mechanical breaker (S) and an electronic overvoltage protection circuit (B, B) comprising at least one transistor. The DC current interruption system of the invention furthermore comprises an electronic opening system () comprising a passive circuit able to auto-bias the electronic protection circuit (B, B) upon the opening of said primary mechanical breaker (S), so as to trigger a switching of said at least one transistor (M, M, IG) making it possible to limit the voltage and the current in the DC line, total interruption of said DC line being obtained by subsequent opening of said secondary mechanical breaker (S).
