METHOD AND DEVICE FOR DETECTING ABRASION QUANTITY OF FRICTION ELEMENT FOR MECHANICAL BRAKE IN ELECTRIC CAR, AND METHOD AND DEVICE FOR DETERMINING COST FOR REGENERATION INVALIDATION PREVENTION

摘要

PROBLEM TO BE SOLVED: To solve a problem of increase of brake pad exchanging frequency to increase brake pad exchanging work frequency as regeneration invalidation occurs in a case of operating an electric car using regeneration brakes. SOLUTION: A regeneration invalidation preventing device 50 is provided in a substation 5 to supply power to an electric car 1 that is operated along a track 3 and a feeder 4, so that regeneration power is accumulated. Generation of regeneration invalidation is detected by a regeneration invalidation detector 12 mounted on the electric car 1, and abrasion quantity of a brake pad is determined for each electric car 1 in accordance with the number of generation of regeneration invalidation by a data processing device 21.
