FUNCTIONAL CHARACTERISTICS
The interruption is carried out in the load-break switch FN*2/**2, by a blow which strikes, deionizes and extinguishes the arc in a very short time. The compressed air required for extinction is produced, during opening operation by the motion of the cylinder(1) which acts also as moving contact, with respect to piston(2) housed inside and secured to the base of fixed cylinder(4).
Through the special shape of tuyere(3) currents of some hundreds of amperes are interrupted by a limited yet sufficient air volume.
As pressure increased gradually, this facilitates the interruption of inductive currents without causing dangerous overvoltage while a quick dialectical regeneration between contacts ensuing the blow and the high separation speed of moving contact, makes easier also the interrupting of capacitive currents.
In comparison with gas self-generating apparatus they have also the advantage of not undergoing, perceptible alteration after each interruption.
