POWER SYSTEM FOR FIRING GUIDANCE DATA CONTROL SYSTEM Russian patent published in 2003 - IPC

FIELD: electrical engineering; power distribution systems for feeding firing guidance data-control systems. SUBSTANCE: power system intended to supply with power firing guidance data-control systems with centralized power distribution among group of controlled entities under pre-start and starting conditions that has no-break power generating set, central control unit incorporating central computer, on- board equipment power modules, as many as there are controlled entities, each of them incorporating voltage changer, ground detector connected to output of secondary power supply, and switching device is provided with newly introduced n peripheral devices for communication with controlled entities each of them incorporating m on-board equipment power modules and additional computing module, m start circuit power modules, and at least one additional secondary power supply; connected to outputs of the latter are main supply inputs of start circuits main power module; each of them is made in the form of switchgear having isolated outputs for sequential voltage supply to respective actuating mechanisms of pre-start and starting circuit of controlled entity; like-polarity leads of each pair of secondary power supplies in power modules of on-board equipment are interconnected by means of jumpers incorporating contacts of switch controlled by flag indicating enhanced power intensity of controlled entity. EFFECT: enlarged functional capabilities, reliability, and reduced failure probability of power system. 1 cl, 5 dwg
