FIELD: electricity. ^ SUBSTANCE: electric power distribution system includes power supply unit, hardware power supply circuit switches connected to power supply unit buses, hardware power supply circuit switch control unit and resistors which have equal nominal values in pairs. Output buses of power supply unit are connected with item housing ("grounding") via the first pair of additional resistors, with hardware power supply circuits also linked with item housing ("grounding") via the other pairs of additional resistors. ^ EFFECT: improvement of system serviceability by static electricity charges removal and voltage removal at switches. ^ 1 dwg |
