TWO-CHANNEL D C SYSTEM FOR VEHICLE Russian patent published in 1999 - IPC

FIELD: electrical engineering. SUBSTANCE: invention is related to electricity distributing D C networks meant to feed functional elements of various vehicles, predominantly flying vehicles. Primary and emergency buses of central switch gears are connected in series in proposed system. Buses of users of first and second categories of each of functional switch gear that are fitted with switching-on contactors are connected to them in each channel. In each central switch gear primary bus is connected to one of three rectifiers. Power diodes are installed in each central switch gear between primary and emergency buses. One of rectifiers is connected to strap between primary buses of central switch gears in section between fuses. Emergency buses are connected to storage batteries. Some users are connected to both buses of users of first category of proper functional switch gears via isolation diodes. System is characterized by high reliability and survivability thanks to increased degree of redundancy of power supply to users of first category. EFFECT: high reliability and survivability of proposed system. 2 c, 2 dwg
