FIELD: power engineering; transportation.
SUBSTANCE: group of inventions relates to vehicle electrical traction system powered by own power supply sources. Power accumulation subsystem comprises metal housing, power accumulation system and electrical protective devices. Energy accumulation system is mechanically secured inside metal housing and includes capacitor modules with several supercapacitors. Supercapacitors are electrically connected in series to each other and located inside metal shell. Electrical protective device is made with possibility to open electric circuit so, that metal housing or supercapacitors bank were connected with electrical grounding. Power accumulation system comprises power accumulation subsystem. Railway vehicle contains accumulation system.
EFFECT: technical result consists in improvement of supercapacitors banks protection in case of internal insulation fault.
