Appointment

The power distribution device (PDP rack) is designed to power the GES container hardware with the required number of lines of a certain capacity and provides separate inclusion of hardware (TC) inside and outside the GES container for different types of voltage.

The PDP rack consists of three panels:

- Power-Up Panel;

- AC Panel;

- DC Panel 28 V.

All loads (TS) are functionally divided into 2 groups:

1 redundant (from UPS) - input 380 V UPS FEED;

2 non-redundant (without UPS) - input 380 V Non UPS FEED.

In terms of power consumption, both groups of vehicles are identical and are designed for a load of 30 kVA each.

The PDP rack provides the ability to connect to the common input 380 MAIN FEED without a UPS container of the entire load (both groups of vehicles) with a total power consumption of 60 kVA, while the groups of vehicles are combined at the output by the power contacts of the KM4 contactor of the Power-Up Panel.

The Power-Up Panel commutes input voltages and provides inclusion / protection of each vehicle group. At the same time, the inclusion of 380 UPS FEED, 380 NonUPS FEED inputs with 380 MAIN FEED input is excluded by blocking auxiliary contacts of the contactors KM1, KM2, KM3.

On the panel for each input there are circuit breakers (QF1, QF2, QF3), RCD units (Over Power Protection 1, Over Power Protection 2, Over Power Protection MAIN), voltmeters with a switch (Voltage Control 1, Voltage Control 2, Voltage Control MAIN ), contactors (KM1, KM2, KM3), lamps for signaling the presence of input voltage "380V" "A", "B", "C" at each input.

The panel has an Operation Life Hour Meter and is connected to the UPS FEED input.

The “FDAS” fire alarm, the “Emergency Lighting” alarm system, and the “Sockets 220V” sockets through circuit breakers of the required power (QF4, QF5, QF6) are directly powered from the Power-Up Panel. A red FIRE fire alarm lamp is installed on the panel, which lights up when a signal comes from the GES container.

The voltage of 380 V is supplied to the “AC Panel” by two cables to each functional group of devices.

AC Panel distributes voltage to individual consumers of each group through circuit breakers of the required capacity:

- 8 output circuit breakers (QF1-QF8) of 1 group;

- 8 output circuit breakers (QF10-QF14) 2 groups.

Individual consumers receive voltage through switches SA1, SA2 - or from input 380 UPS FEED or input 380 Non UPS FEED:

- output "ECU2" (QF9);

- exit "380 C-Band Steller".

On the panel there are lamps for signaling the presence of voltage at each output with the corresponding marking.

The DC Panel 28V distributes 28 V loads to 10 load consumers.

The panel has 4 inputs PSU outputs, there are lamps for signaling the presence of voltage at the input (HL1, HL2, HL8, HL9) with the corresponding marking.

Switching and protection on 28 V circuits is provided by circuit breakers QF1-QF4, QF6-QF11. Signaling lamps with appropriate markings indicate the presence of voltage at each output. The DC Panel 28V is equipped with a QF5 “RAD Alarm” circuit breaker and an HL7 lamp for signaling the presence of radiation, voltage is supplied to the circuit breaker from the AC Panel from the “220 V PSU # 1” output.
