REGENRATIVE ENERGY.

All 3 Phase locomotives are equipped with Regenerative Features:

PCEE’s Directives to LPs to aim for 15-17% Regenerative.

Grade “A” Loco Pilot Achieves: 17%

20-25% achieved on Ghat Section over DHN Division.

A part ofRegular Counseling and monitoring activity.

Other Advantages:

Less releasing time while negotiating speed restrictions

Lesser requirement of pneumatic pressure i.e increased life span of compressors and Brake Rigging Equipment saves in maintenance cost.

Minimizes Jerks in Train Operations.

Less wear and tear of wheels and Rails.

Reliability Improvement Initiatives

3-Phase electric locomotives:

Traction Motors:

Full greasing of Traction motor’s bearings to arrest TM bearing seizure.

Timely replacement of TM pinion & bearings and clearing all overdue backlogs.

Pneumatic:

Replacement of Air flow gauge glass every year to arrest ageing effect.

Provision of BP+FP protection plate to prevent CRO related failure.

Checking of temperature and speed sensors of TMs during IC &Major schedule inspection to detect sensor failure.

Complete sealing of VCB to arrest moisture ingress.

 

 

Reliability Improvement Initiatives

   3-Phase electric locomotives:

Establishment of test set up:

For interconnected Loco bus station network for electronics card testing.

For lightning arrestors, various types of indicating meters.

Hotel load test bench to check HOG working all WAP7 Locomotives are Hotel Load Compliant.

 

   Auxiliary Machines:

Conversion of single phase supply into three phase supply for auxiliary motors.

Double varnishing and heating of auxiliary motors to arrest auxiliary motors insulation failure.

 

 

 

 

Reliability Improvement Initiatives

3-phase Electric locomotives:

Implementation of RDSOs MS/SMIs/Tech. Circulars on priority.

Checking of Angle transmitter/Throttle to arrest calibration defects during IC inspection.

RDPT of all types of damper base and other safety gears to detect welding defects.

Conversion of 18 Nos. of GTO based loco into IGBT propulsion based loco.

Conversion of PBU/TBU type brake rigging into conventional type brake rigging system to arrest brake hanger breakage cases.

Cleaning of vent plug of gear case to remove heat from gear case oil.

Ensuring 100% working of all 8 sanders before shed out.

Modification of Vertical damper base to arrest vertical damper failures.

Starting of No load run test of three phase traction motors on bogie to check heating performance of bearings.

Replacement of nylon tube by copper tube with double ferrule to prevent failure of harmonic filter pneumatic circuit.

Provisioning of VCU reset switch to prevent air pressure drop during VCU resetting.

 

 Reliability Improvement Initiatives

Conventional Electric locomotives:

Establishment of test set up: For Electro Pneumatic and Electro Magnetic Contractors.

Replacement of MPCS of make Steaslit, SIL and ICEPL since the firms are closed and no support of spares or AMC is there.

AMC of all electronic equipment’s like SIV, MPCS for enhancing loco reliability, since works are on progress and completing this year.

Replacement of over aged equipment like Auxiliary machines, traction motor bearings, relays on priority.

Mid-term rehabilitation of transformer & Tap Changer after service of 18 yrs.

Provision of Trap chamber for collecting coal/dust particles coming from BP pipe in A9-BP circuit as per RDSO MS no-RDSO/2017/EL/0463 on priority.

RDPT &MPT test of all Hitachi TM nose stay.

 

 

 

 

 

 

Distributed Power Wireless Control System

Benefits of DPWCS:

Multiple operation of Locos with wireless technology.

Provides coupling between locos through RF communication.

Coupling of maximum of 4 locomotives.

Locomotives can be connected in between or at the end of the train.

Suitable for long haul – freight loads beyond 5400T. & Energy efficient for modulated terrain like ECR.

 

Status over ECR

08 pair of WAG-9H of ECR fitted with DPWCS & are operational over IR.

RSP sanction available for further provision: WAG-9H – 10 pairs, WAG-7 – 10 pairs

Decision be taken for hauling loads beyond 5400T with DPWCS over ECR.

Crew Voice and Video Recording System

Objective:

Recording all type of communication including gestures in real time.

HIRA (Hazard Identification and Risk Analysis) to meet operational requirement.

Highlighting occurrences of non-standard/unusual/unsafe circumstances.

Deliverables:

Improving Driver’s skill and driving technique.

Identification of operational risk. & Pin pointing of key areas of concern.

Training aid to the crew. & Investigation tool for risk mitigation.



Crew Voice and Video Recording System

                       System Components:

Camera (up to 8 nos.)

DigitalVideorecorderwithEncoder, Decoderandprocessingsystemand data storage memory.

DC-DC Converter to feed the system from loco control voltage (if required).

Microphone for voice recording.

LCD based display for health indication.

 

 

                      Fitment Locations:

Camera (08 nos.)

02 nos. in each Cab.

01 no. at front (Cab-1 & 2 side).

01 no. at Top (Cab-1 & 2 side).

DVR:

On side wall (behind SB-1 panel).

LCD Display:

Above Speedometer in each cab.

02 Nos. of ECR locos (32150 & 39117) provided with CVVRS.

36 sets material received for further provision .

 

 

                            Hotel Load Converter

Coach loads ((AC & Lights) are fed through OHE power - Reduction in Noise & Air pollution.

Reduction in HSD oil consumption.

Elimination of diesel power car in future - possibility of carrying extra passenger coach.

Saving to the tune of Rs. 50 Lakh per loco per year with rate of return 35%.

All WAP-7 loco of ECR have been provided with Hotel load converter & made HOG compliant.

Total 37 nos of passenger trains run on HOG over ECR.
