ZERO CURRENT PULSE WITH THE CONSTANT CURRENT STEEPNESS FOR THE DIRECT CURRENT INTERRUPTION Russian patent published in 2018 - IPC H01H33/59 

FIELD: instrument making.

SUBSTANCE: invention relates to the zero current pulse generation device (1) for the zero current passage generation in the electrical component (3), through which the direct current (2) flows, in particular, the switching vacuum tube, wherein the device comprises the electric energy accumulator (4) with two poles (12), (13), through which the electric energy accumulator (4) can be charged from the voltage source (10), and the switch (5), at that, with the said device via the electric component (3) electric energy accumulator (4), through which the DC current flows, and the switch (5), a closed loop can be created so, that with the switch (5) closing the electric energy accumulator (4) can be discharged during the zero current pulse (1) generation, flowing through the electrical component (3) opposite to the direct current (2). In accordance with the invention it is provided, that the electric energy accumulator (4) comprises plurality of energy accumulator elements for the zero current pulse (1) co-generation.

EFFECT: technical result is ability to interrupt the of various heights commutation currents with, if possible, constant current steepness dI/dt.
