PANTOGRAPH VOLTAGE DROP TYPE PANTOGRAPH BOUNCE MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a pantograph voltage drop type pantograph bounce measuring device capable of detecting pantograph bounce occurrence by detecting a fine voltage drop generated at a pantograph bounce time by measuring an on-vehicle voltage.;SOLUTION: This pantograph voltage drop type pantograph bounce measuring device includes a voltage drop detection part 5 connected to a wire 4 from the pantograph 3, a high-pass filter (HPF) or a frequency analyzer 6 connected to the voltage drop detection part 5, and a voltage drop type pantograph bounce measurer 7 connected to the high-pass filter (HPF) or the frequency analyzer 6. Consequently, the occurrence and finish of the pantograph bounce of the pantograph 3 can be measured surely.;COPYRIGHT: (C)2008,JPO&INPIT
