As a rule, traction current lines use single conductors, however for the supply of railways with high traffic and in particular for the supply of high speed railway lines, two bundle conductors are used.
What do you mean by traction system?
The traction system is a component of the train. It is a system installed on the roof or underneath the train. The traction system converts the electrical energy, collected from the catenary via the pantograph, into mechanical energy, thus enabling the wheels to turn and, therefore, the train to accelerate and brake.
What is traction voltage?
The voltages used for traction current lines are 110 kV in Germany and Austria and 66 kV or 132 kV in Switzerland. Traction current lines are operated symmetrically against earth. In the case of 110 kV lines, for example, each conductor has a voltage of 55 kV against earth.
What is traction in electrical engineering?
Electric Traction- The system which use electrical power for traction system i.e. for railways, trams, trolleys, etc. is called electrical traction. OR Electric traction means a locomotion in which the driving force is obtained from electric motors. It is cheapest method of all other methods of traction.
What is meant by traction power?
Traction Power means power supplied by the traction substations to the Traction Electrification System for the Commuter Rail Network expressed in megawatt-hours. Sample 1. Save. Copy. Traction Power means the propulsion energy required to operate Trains.
What is meant by traction system?
Dictionary - Traction system It is a system installed on the roof or underneath the train. The traction system converts the electrical energy, collected from the catenary via the pantograph, into mechanical energy, thus enabling the wheels to turn and, therefore, the train to accelerate and brake.
What are the four main parts of the traction power system?
Main components of electrical traction systems: electric power sources, traction power substations and tractive engines. Type of the contact line systems: non-compensated, semi-compensated and compensated. Mathematical model of the train movement: regime of traction vehicle drives.
What are the different types of traction system?
- Direct Current (DC) electrification system.
- Alternating Current (AC) electrification system.
- Composite system.
What is traction power supply?
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply
