2. ELECTRIC LOCOMOTIVES
An electric locomotive is a locomotive powered by
electricity from overhead lines, a third rail or an
on-board energy storage device such as a
chemical battery or fuel cell.
4. INTRODUCTION
• Locomotives in india consist of electric and diesel
locomotives. Locomotives are also called locos or engines.
• Electricity is used to eliminate smoke and take advantage
of the high efficiency of electric motors; however, the cost
of railway electrification means that usually only heavily-
used lines can be electrified.
• the power for electric locomotives can come from clean
and/or renewablesources, including geothermalpower,
hydroelectric power, nuclear power, solar power and wind
turbines.
5. HISTORY
• 1st Electric locomotive was built by:-
chemist Robert Davidson of Aberdeen
in 1837 & powered by ”BATTERIES”.
6. OVERVIEW OF ELECTRIC
LOCOMOTIVE
• electriclocos are running through
Electricity with the help of overhead
line.
• Pentagraph is used to connect
the loco with overhead line.
• Pantagraph draws 25 KV of
electricity from overhead line, which
Is very high AC voltage.
7. Parts Of Electric Locomotive
• Transformer
• Rectifier
• Arno Convertor
• Traction Motors
• Air Compressors
• Motor-Alternator
10. INTERNAL PARTS OF CAB
• Buzzers
• RHS Loco Control Desk
• Central Portion
• Ammeters & Voltmeters
• LHS Corner Of The Cab
• Brake Air Pressure Gauges
• Transformer
• Smoothening Reactors
• DJ Main Contactor
11. ADVANTAGES OF THREE PHASE
TECHNOLOGY
• It Require little maintenance.
• 3-ɸ drive allows regeneration and unity power
factor operation.
• It improves operational efficiency besides
reduction in maintenance efforts. The energy
saving due to regeneration and improved
power factor sizable.
12. ADVANTAGES OF ELECTRIC
LOCOMOTIVE
• Electric engines do not produce much heat
and noise.
•Electric engines do not produce smock
• Electric engines are therefore easier to maintain whereas
the moving parts of a diesel engine require constant
maintenance.
• The simple nature of the electric engine makes them
efficient and powerful.
13. CONCLUSION
• Main Objective in this presentation learn about electric
locomotive in Railways.
• we learn that electricity is used to eliminate smoke and take
advantage of the high efficiency of electric motors.
• we also learn in basic of working system of electric
locomotives.
