Abstract (en)
The circuit breaker presents two chambers (11,12) and collectors (13,14) which are connected to a variable resistor (1). The resistor has a tubular shape and is made up of a number of elementary resistors (2). Each elementary resistor has a polymer matrix with carbon fragments in suspension and two parallel electrodes (4,5). The electrodes are flat and made of copper. The whole resistor is covered by a protection envelope (6) with ventilation openings (10).
