1 PRAIRIE MINES AND ROYALTIES PAINTEARTH MINE MARION 8200 DRAGLINE ELECTRICAL UPGRADES

2 PAINTEARTH MINE LOCATION EAST CENTRAL ALBERTA

3 DRAGLINE ON TUB CHANGE PAD, BOOM DOWN

4 ACE OPERATOR WHO GOT US THIS FAR

5 WORK SCOPE: ELECTRICAL SUPPORT TUB CHANGE INSTALL DC WELDING OUTLETS ALONG BOOM REPLACE WESTINGHOUSE ANALOG REGULATOR WITH DCS SYSTEM, CONTROLLOGIX AND SIEMENS DC CONVERTERS REWIND THE STATOR OF 2 WESTINGHOUSE 3500 HP SYNCH MOTORS INSTALL DCS SOFT START USING DRAG GENERATORS AS MOTORS TO BRING SET UP TO SPEED UPGRADE EARLIER STATIC EXCITER TO SIEMENS DRIVES INSTALL NEW OPERATOR SEAT, UPGRADE PANALVIEW HMI UPGRADE ALL SLC500 TO CONTROLOGIX

6 WORK SCOPE 2 REMOVE SEVERAL GENERATORS FOR OVERHAUL AND RE- INSTALL, PEDESTAL BEARINGS FOR UNITS CHANGED AT THE SAME TIME VCB CONTROL CHANGES SYNCH MOTR ROTOR FIELD FROM 1 SPLIT DRIVE TO INDIVIDUAL DRIVES (INSTALL LINE REACTORS, SECOND DRIVE AND STANDARDIZE TO NEW FIELD APPLICATION CONTACTORS MODIFY PCR ROOM BENCH CHANGE OUT BRUSH HOLDERS ON HOIST, DRAG AND PROPEL MOTORS-CONTRACTOR

7 WORK SCOPE 3 SWING MOTOR 4 OVERHAUL ELIMINATE HOUSE VOLTAGE, NO DC CONTROL, ALL AC, ONLY REAL ISSUE WAAS THE TIME TO GET AC BRAKE SOLENOID COILS ELIMINATE SELSYNS FOR SHOE POSITION, REPLACED WITH RESOLVERS TO MATCH DRUM RESOLVERS

8 SCOPE ADDITIONS HV COLLECTOR RINGS, BADLY UNDERESTIMATED THE WORK REQUIRED TO REMOVE AND RE-INSTALL 7.5 MVA TRANSFORMER PROTECTION UPGRADE FROM AMPTECTOR TO STARTCO FPS RELAY

9 STATIC MOTOR FIELD UPGRADE ORIGINAL UPGRADE FROM DCS DONE IN 1997 HAD ALREADY STARTING CONVERTING TO SIEMENS DRIVES AS THE OTHERS BEGAN GIVING PROBLEMS ORIGINAL SLC500 PLC CONVERTED TO CONTROLLOGIX SWING MOTOR FIELD OVER-SIZED TO PROVIDE ARMATURE CURRENT FOR DRAG GENERATOR ARMATURE IN MOTORING ROLE DURING SOFT START

10 MOTOR FIELD BEFORE UPGRADE

11 MOTOR FIELD IN PROGRESS

13 MOTOR FIELD ALMOST COMPLETE NOTE: SHIELD FOR TWISTED PAIRS BROUGHT UP CLOSE TO TERMINATION POINT INSTEAD OF BEING ENDED AT TECK CONNECTOR

14 COMPLETED STATIC MOTOR FIELD UPGRADE

15 PLC UPGRADES PURCHASED PLC AND PROGRAM FROM DCS OPEN PROGRAMMING HUGE PLUS ORIGINALLY PLANNED ON LEAVING SOME SLC500, HAD TIME TO CHANGE OUT,FAR BETTER THAN COMMUNICATING TO THE SLC500 FROM THE CONTROLLOGIX ISSUES WITH SAVING MULTIPLE PROGRAMS FOR MULTIPLE PROCESSORS GOES AWAY, JUST 1 PROGRAM TO BACK UP AND UPDATE. JUST ONE BATTERY TO BE CHANGED USED ETHERNET COMMUNICATIONS, ALL OUR DEVICES NOW ARE ETHERNET EXCEPT FOR THE SIEMENS DRIVES ALL PLC S AND CONTROL ARE SUPPLIED FROM CONSTANT VOLTAGE TRANSFORMERS. CVT S HAVE OPERATED SUCCESSFULLY FOR SEVERAL YEARS ELIMINATING DIPS ETC THAT MAY HAVE DROPPED OUT PLC AND GOT A RE- BOOT, ORIGINAL UPS S DID NOT PROVIDE WHAT WE NEEDED ETHERNET, DIFFERENT SWITCHES FOR DIFFERENT CRITICALLITY LEVELS, ONE SWITCH JUST FOR PLC RACKS, ONE SWITCH FOR OTHER ELECTRICAL, ONE SWITCH FOR IT FUNCTIONS, FIRE WALL SECURITY

16 PLC UPGRADES

20 GENERATOR FIELD DRIVES

23 NEW INSTALLATION

24 TEST PANAL

28 TYPICAL CABLE TERMINATIONS

30 DRIVE TRANSFORMERS

33 SYNCH DRIVES

34 ONE OF 2 LINE REACTORS ON THE SYNCH DRIVES TO ALLOW USE OF 2 DRIVES ON 1 TRANSFORMER LINE REACTOR

35 MG SET HOLE WITH GENERATOR GONE. WE CLEAN UP AND PAINT WHILE UNITS ARE OUT

36 OPERATOR CAB / SEAT

38 SOFT START

39 SHAFT THREADED IN END OF STUB SHAFT TO MOUNT GEAR FOR SPEED SENSOR GEAR FOR SPEED SENSOR SPEED SENSOR PICKUP

40 THE ONLY PROBLEM WE HAD WITH THE SPEED SENSOR WAS TO GET A SMALL ENOUGH RUN-OUT FOR THE SHAFT THAT HELD THE GEAR. ONE MG SET WAS OK, THE OTHER HAD 15 THOU RUN OUT AND GAVE US INTERMITTANT ALARMS. ARMATURE WAS EVENTUALLY CHANGED OUT WITH A SPEC TO MAKE SURE RUN OUT WAS OK

41 ORIGINAL AMTECTOR PROTECTION RELAY

42 START PANAL ALMOST COMPLETE ELIMINATED A LOT OF THE ORIGINAL METERING AS IT WAS ALL INCORPORATED IN THE STARTCO FPS RELAY STARTCO RELAY FACE PLATE

43 HV COLLECTOR RINGS

46 TEMPORARY POWER MCC WRAPPERS WITH WELDING RECEPTACLES IN COVER

47 SYNCH MOTOR RTD JB

48 PROBLEMS FALSE GROUND CHECK TRIPS WHEN THE MACHINE WAS SPLIT, SOLUTION SEEMED TO BE BONDING WIRES BETWEEN REVOLVING FRAME, SHOES, AND THE TUB. NEXT TIME WOULD LIKE TO RUN EXTERNAL GROUND WIRE, INSPECT DAILY AND USE PILOT AS EMERGENCY TRIP ONLY. WRONG RATING OF LIGHTENING ATTESTORS, 18 KV, ALL FAILED WITH FIRST TRAIL CABLE GROUND FAULT NOT ENOUGH HOURS PLANNED FOR CONTRACTOR SUPPORT, TOOK AWAY MINE ELECTRICIANS AT CRITICAL PHASES OF ELECTRICAL JOBS DECISION TO RAISE BOOM ON DRAG INSTEAD OF HOIST (BULL GEAR TOOTH FOUND MISSING AFTER BOOM LOWERED)

49 THE END THANK YOU
