Oil Cooling System is used for removing the heat
due to energy loss from the transformer oil cooling
circuits, the choke and the inverter. Oil Cooling
System is used in WAG9, WAP7 & WAP5 class
of locomotives manufactured by Chittaranjan
Locomotive Works, India. Two such units are
used per locomotive. The Oil Cooling Blower's are
used for cooling the oil of transformer and three
auxiliary converters that flows through the heat
exchanger assemblies.
The oil of the transformer flows through the
radiator 1 that is mounted under the floor of the
locomotive. The oil carrying the heat from auxiliary
converter flows through the radiator 2 that is place
right above the radiator 1 of transformer under the
locomotive floor.
The Oil Cooling Blower is mounted right above
both the radiators 1 & 2 inside the locomotive such
that the fresh cooling air is sucked from the top
of the locomotive by Oil Cooling Blower through
the duct connected to the top of the Oil Cooling
Blower box cools the radiators at the other end of
the box.
The Oil Cooling Blower box is connected to the
roof opening of the locomotive through a duct
and cyclonic filter at the roof. This cyclonic filter
is responsible for filtering the incoming cool air
that is sucked by the Oil Cooling Blower and this
cool air takes off the heat from the radiator fins
through convection method and escapes out from
the bottom of the locomotive.
This product is a patented product of DRESPL and
Oil Cooling System is designed in such a manner
that the deflectors at the bottom distributes air
evenly over the entire radiator so that no high
temperature points are left anywhere in the
radiator. |
