Radio frequency (RF) induction heating has been proposed as an alternative deicing technique for automatic guideway transit (AGT) collector rails under adverse weather conditions. The concepts of a practical RF deicing system are discussed. A working frequency of 450 kHz is used for the RF generator, and 430 magnetic stanless steel is selected as the rail-capping material for efficient coupling. Experimental setup for a model RF deicing system is described. With 2.5-kW RF generator power, successful deicing was accomplished up to a rail speed of 3.2 km/h for rail temperatures as low as -30 deg C. The performance of this test system is assessed, and possible future improvements are suggested. (Author)
