Background and overview
313-5300 series suburban DC electric multiple unit (EMU) trains build for
rush-up operations are operated with 313-0 series, 313-5000 series or 311
series. One 2-car set consisting of one powered vehicle and one trailer
vehicle was delivered in 2010.
Car body
They have 2930mm wide body, incorporating light weight stainless construction.
They employ the roof plated integrated with rain water gutters for cost
reduction. Their pier panels (strength members) are also gotten rid of
to match various seating arrangements. Their bodies are unpainted and have
the orange waistline and headline bands running through the length of each
car below and above the windows. Their gangwayed cab end section painted
in white is constructed by steel. Their headlights are changed into projector
type high-Intensity discharge (HID) lamp and LED lamp. Anti-fall plates
between vehicles are also introduced excepting the cab end. They are equipped
with three 1300mm wide double-leaf automatic sliding doors on each side
of the vehicles. Horizontal band of 5 set fixed windows having 930mm height
are fitted between the doors and hopper windows are at the end of their
body. Double-glazing UV cut glass is employed for all windows to improve
noise insulation property and to prevent dew condensation. Full-colour
LED destination indicators are fitted on the side of their body and a full-colour
LED destination indicator and a full-colour LED train-type indicator are
fitted at the front of end vehicles. Two air conditioners, C-AU715, rated
at 21,000kcal/h/unit and employing R407C refrigerant, and no ventilators
are fitted on their roof. Loudspeakers, providing guidance broadcast for
passengers waiting at a station, are fitted on their roof. End cars are
equipped with the automatic jumper coupler to ease rush-up operations.
Bogies
Motored bogies are C-DT63B and trailer bogies are C-TR251A, featuring bolster-less
secondary air suspension, corn-shaped multilayered rubber spring journal
supporting system, and the single link traction device. The yaw dampers
are adopted to ensure smooth ride characteristics even at 120km/h. Twin
Disc (TD) flexible joint employing deflecting plates made of carbon-fiber
reinforced plastic (CFRP) is applied for power transmission device. Motored
bogies employ the single tread brake device adopting automatic gap-adjusting
unit, and trailer bogies employ both the double disk brake device and the
wheel tread cleaning device.
Traction unit and ancillary equipments
Their powered end vehicles, class kumoha313-5000, and their powered intermediate
vehicles, class moha313-5300, are equipped with a 3-step Variable-frequency
drive (VFD) traction system, C-CS37A, featuring Insulated Gate Bipolar
Transistor (IGBT) and controlling four asynchronous traction motors, C-MT66C,
with a power output of 185kW on truck basis. This traction system is integrated
with the auxiliary power supply unit with a power output of 150kVA (class
kumoha313-5000) or 80kVA (class moha313-5300). In case of the auxiliary
power supply unit failure, one VFD unit for traction motor drive can switch
to supply electricity as the backup auxiliary power supply unit. On the
other hand, powered intermediate vehicles, class moha313-5000, are equipped
with a traction system, C-CS38A, controlling four traction motors. Powered
vehicles are also equipped with a single arm type current pickup, C-PS27B,
on their roof. Trailer vehicles are equipped with a motor driven air compressor,
C-C1000ML, under their floor. 313-5000 series feature the electric commanding
brake with mixed regenerative-dynamic braking and holding brake, featuring
brake control of trailer priority and electric braking to zero speed.
