3. INNOVATIONS WITH GOOD PHOTOGRAPHS

1.Modification of AAL/BT VCB by providing in Built pressure gauge

TITLE: - Provision of in Built pressure gauge to check & trouble shoot in the
cases of DJ feedback fail/VCB stuck off/VCB Stuck on and during schedule

maintenance.

OBJECT: - There are several cases of pressure drop in VCB of all makes.

During schedule maintenance/trouble shooting of locomotive PRV/QPDJ
pressure setting is required to be check & adjust if any abnormality noticed.

In SEIL/GEC ALSTOM make VCBs, in built pressure gauge is available with the
range of 0-10kg/cm² and it shows the actual pressure of the VCB. Where as
in AAL/BT make VCBs, due to non availability of in built pressure gauge,

needs draining of air tank, isolation of Pneumatic circuit to VCB and provision
of external pressure gauge during every time of trouble shooting/schedule

maintenance of locomotive and it requires additional man
hours/maintenance. To avoid difficulty in trouble shooting/schedule
