FIELD: electricity.
SUBSTANCE: method for switching operating current in the mesh grid (1) of the constant voltage is proposed. Wherein at least one inverter (2) connected to the DC voltage grid is adjusted so that in the switch branch with the mechanical switch (6) the transition through zero current is caused, and the mechanical switch (6) is actuated depending on the created passage through zero current.
EFFECT: possibility to switch operating currents in the constant voltage grid in both directions in an economical manner.
