MIDI OHL

!   How to accept 1600mm pan heads with 90m spans?

!   Simulations have shown that: !   Without wind, 1600mm can be

used !   Particular points in stations to

be studied !   If wind risk too high: add pole at

span- midpoint


SIMULATION TO STUDY PAN HEAD COMPATIBILITY WITH OHL GEOMETRY !   Multibody simulation associated with dynamic use, geometry and

pantograph kinematics :

DYNAMIC SIMULATION


!  To study the TSI compliance of the OCL designs, some new functionalities were added to the OSCAR software

!  Fully flexible multibody model of the pantograph is now available

!  It allows to study accurately interaction between the CW and pan heads and contact strips

SIMULATION TO STUDY PAN HEAD COMPATIBILITY WITH OHL GEOMETRY


CONCLUSION 1 Electrification system

Type of OHL To accept solution

25kV 50Hz 50’s type

TSI 1,95 Check bridges and tunnels

Adapt design for Fm 25kV 50Hz V200 TSI 1,95 Check bridges and

tunnels

25kV 50Hz V350 And former types

High Speed

TSI 1,95 OK

Check very particular points

1500V dc compound TSI 1,60

TSI 1,95

Decrease Fm

Decrease Fm 1500V dc “midi” Not tensioned

90m spans

TSI 1,60 Decrease Fm and adapt geometry with new poles if wind risk


CONCLUSION 2

• There are many possibilities to accept pan heads • The worst case is due to bridges and tunnels • In no windy situation 1600mm panhead can circulate under 1950mm OHL needing a risk management

• Simulation helps to check compatibility • French TSI OHLs accept both TSI euro-panheads
