TEST REPORT AND DESIGN ANALYSIS-HIGH SPEED, THREE PHASE, ALTERNATING CURRENT CONDUCTOR-COLLECTOR SYSTEM

THE AC CONDUCTOR-COLLECTOR SYSTEM FOR BART IS COMPOSED OF MODULAR COMPONENTS AND A MINIMUM NUMBER OF HARDWARE TYPES. THE SYSTEM IS DESIGNED TO ABSORB ABUSE AND TO PROVIDE LONG SERVICE LIFE BY USING HEAVY DUTY MATERIALS, WITHOUT BULK OR DEAD WEIGHT. ONLY THERMOSETTING PLASTIC MATERIALS ARE USED DUE TO THEIR DIMENSIONAL STABILITY, THEIR RETENTION OF USEFUL PROPERTIES OVER A WIDE RANGE OF TEMPERATURES AND HUMIDITY, THEIR GOOD AGING CHARACTERISTICS, AND THEIR EXCELLENT CHEMICAL AND WEATHERING RESISTANCE; HOWEVER, EVEN WITH SUCH CHARACTERISTICS, NO PRESENTLY AVAILABLE THERMOPLASTIC RESIN IS YET SUITABLE TO MEET THE LONG TERM EXPOSURE AND OPERATIONAL ABUSE REQUIRED FOR RAPID TRANSIT SYSTEMS. SHORT CIRCUIT AND SAFETY COVER TESTS WERE RUN, AS WELL AS TESTS TO EVALUATE COLLECTOR AND CONTACT SHOE OPERATION AND WEAR, CONDUCTOR RAIL WEAR, AND AUDIO NOISE. TESTING WAS ALSO CONDUCTED TO DETERMINE TRANSIENT VOLTAGE LEVELS AND THE EFFECTS OF RADIO NOISE ON VOLTAGE. TEST RESULTS REVEAL THAT HIGH SPEED (UP TO 80 MPH) CURRENT COLLECTIONS AT THE REQUIRED ELECTRICAL POWER LEVELS (4160 VOLTS AND UP TO 160 AMPERES) ARE BOTH FEASIBLE AND PRACTICAL. THE AUTHOR ILLUSTRATES THE SYSTEM AND DESCRIBES IN DETAIL THE SYSTEM AND THE TESTS CONDUCTED. /UMTA/
