Microprocessor-based automatic control unit for dc systems in power facilities (MSAPT)
The unit provides monitoring of condition and control of equipment of mains and DC switchboard, indication of condition of DC switchboard equipment, recording of events during operation of controlled equipment, implementation of automatic control systems for DC systems as parts of power facility automatic control systems. To provide maximum effectiveness, use the automatic switches with independent releases, equipped with numeric protection device for DC connection (ZPT-001, manufactured by OAO “Belenergoremnaladka”).
The unit is constructed as a cabinet with double-sided access. The unit includes:
-
data acquisition unit (USD);
-
voltage control unit (BKN);
-
“Sapfir-4”, a system for automated searching for ground faults in DC circuits;
-
local alarm unit (BMS);
