HIGH POWER SWITCH WITH CURRENT LIMITER Russian patent published in 2018 - IPC H01H33/16 

FIELD: electricity.

SUBSTANCE: invention relates to a high power switch with a current limiter which comprises a main conductive circuit consisting of a hollow tubular main conductor, an inner and outer connecting body, a fixed main contact and an annular movable main contact and an arc suppressed parallel circuit consisting of interrupting device (5), having an arc suppressing function, and current limiter (6); circuit of the arc extinguishing branch is connected in parallel with the main conducting circuit; current limiter (6) serves as a component of the switch and is located in the main conductor; and when the switch opens the short-circuit current, the main conductive circuit opens the first and the current goes to the arc-suppressing branch circuit and current limiter (6) limits the short-circuit current so that it is within the breaking capacity of interrupting device (5).

EFFECT: technical result is to provide the possibility of opening a short-circuit current with a larger numerical value.
