Rail Transit System Solution
Changchun Light Rail Phase III Project
Changchun Light Rail Phase III
Project is a part of Light Rail Line 4, with a total length of 15.953km,
including 2.980km of underground line and 0.412km of transition line and the
rest is overhead line. Changchun Light Rail Phase III Project starts in
Changchun Railway Station North Station in the west and ends in car yard in the
south. A total of 16 stations will be built along the line, including three
underground stations, 13 elevated station 13 and 1 car depot. It is a novel and
beautiful modern rail transit line.
In 2010, Jinguan Electric provided
10kV high-voltage switchgear cabinet and environmental control cabinet for the
power supply system of Light Rail Phase III Project of Changchun Rail Transit.
The products meet the power supply demand and operating environment
requirements of rail transit system in terms of the technical level and
production process. Products of Jinguan Electric were successfully run in
Changchun Light Rail Line 4, marking an imprint of success of Jinguan Electric
in rail transit field.
2. Changchun Metro Line 1 Phase I Project
Line 1 is a north-south rail transit backbone line of Changchun City rail
transit network, passing through 16 stations, with a total length of 18.5 km.
AC 66 / 35kV two-stage voltage centralized power supply mode is adopted for
power supply. Two main substations are set for Phase I Project. Medium voltage
power supply network uses traction and power lighting hybrid power supply
network. Two main substations, 8 mixed traction and step-down substations, 9
step-down substations and 2 follow type step-down substations are set along
Metro Line 1.
In 2015, Jinguan Electric provided AC35kV high voltage switch cabinet,
AC0.4kV low voltage cabinet and environmental control electric control cabinet
for Changchun Metro Line 1 power supply system. SF6 gas insulated AC35kV indoor
armored metal-enclosed high-voltage switchgear cabinet designed by Jinguan
Electric is characterized by small size, anti-condensation, maintenance-free,
intelligent and other technical features, meeting the project substation AC35kV
voltage level power supply needs. AC0.4kV low-voltage cabinet and environmental
control electric control cabinet designed by Jinguan Electric uses Blokset
series cabinets manufactured by Jinguan Electric with the authorization of Schneider.
This series has high protection level, high insulation withstand voltage, rated
current up to 6300A and can withstand 85kA internal arc under 0.5s. This series
not only meet the needs of normal operation and failure modes of project
substation AC0.4kV system but also can achieve intelligent control of
environmental control equipment.
