17. INTRODUCTION OF ELECTRICAL DEPARTMENT IN NMRC
(a) Rolling Stock
• Rolling stock department is backbone of any urban transport
system.
• The term rolling stock in rail transport and metro industry refers to
any vehicles that move on a railway.
• Toshiba has worked to develop the various systems and devices
installed in railway rolling stock to the Train Safety System also
reduce environmental impact when we develop rolling stock
systems.

18. In this department major function-
• First line inspection (Inspection of Trains)
• Second line inspection(Overhauling sections)
• Maintenance of trains

19. (b)Power System(Traction)
• The primary function of the auxiliary power system is to transform the
power from main transformer to AC 415V 50Hz, AC230V 50Hz and
DC110V.
• The converted power is used to supply air-conditioner, air
compressor, oil pump of main transformer, lighting system, signal
system and control circuit.
• Power supply network of auxiliary system includes:
1.Auxiliary converter outputs alternating current of 3-phrase 415V
single-phrase 230V, 50HZ

20. Continue....
2.Battery charger outputs 110VDC.
3.Medium voltage bus (3-phrase 415V, AC, 50Hz)
4.Bus line isolation contactor- It will be opened when there is short circuit in
medium voltage bus
5. Battery，260Ah, Ni-cd battery
6.Workshop Power Supply
7. Low voltage bus(110V DC)
8.Low voltage box.

(c) Workshop Power Supply
1) Workshop power supply includes:
AC415V power supply socket and AC230V on board outlet socket.
In the case of vehicle maintenance, if there is no AC25KV high
voltage power supply, it can still maintain the vehicle.

2) AC415V power supply socket:
When the AC25KV high voltage is not available, the maintenance
personnel can provide the power to the auxiliary electrical
equipment in a unit (DT*M) by the AC415V power supply socket.

HVAC Control

25. 25
General Introduction
In each car, there are two HVAC units, and
each HVAC units has one separate control
system.
This system will control the temperature,
fresh air damper, compressor starting,
smoke alarm, etc.

26. 26

27. 27
Temperature Control
• The control for cooling, heating .
• Cooling:
• Cool1 (50%) will start when the
temperature is higher than the set point.
• Cool2 (100%) will start when the
temperature is 1℃ higher that the set point.

28. • For the Heating, it is just controlled by the
temperature.
• When the temperature ＜18℃(set point), heating will
start.
• When the temperature ＞18℃(set point), heating will
stop.
• When heating is working, ventilating at the same time.

29. 29
Fresh air damper Control
• Fresh air damper is controlled automatically.
• The air-conditioning control system of saloon controls
the opening position of fresh air damper according to
train passenger capacity information transmitted by
the Train Control & Management System (TCMS)
system.
• The fresh air damper in the air-conditioning unit can
achieve six-position adjustment, i.e. closed, 25%, 50%,
75%, 100% and fully-open.

36. General Introduction
The power circuit diagram of NSR1 is shown as Fig.1.
1. The single-phase AC 25KV high voltage from the catenary by means of the
pantograph and connects to the primary winding of main transformer through
VCB.
2. The lightning arrester provides overvoltage protection for the equipments of
power circuit. The arrester at the front of VCB is used to restrain lighting
overvoltage or line overvoltage while the one at the end is used to restrain the
operation overvoltage of main transformer.
3. Potential transformer is used to detect the line voltage, and current
transformer is used to detect the line current.
4. The return current from the main transformer is returned through the earthing
devices of DT car, it’s also connected with the earthing devices of the M car to
improve the redundancy of the earthing circuit.
