Shenyang Metro Line 2 uses LED light source for the first time

On October 17, the Shenyang Metro Command announced the characteristics of the North Extension Line Equipment System on Line 2, and the station lighting will use LEDs for the first time.

It is reported that the three stations and interval lighting use LED light source for the first time, which is more energy-saving without increasing the number of lamps and meeting the lighting requirements. The light source has a longer service life and long-term economic benefits.

The equipment area lighting realizes the sub-control. When the normal lighting is satisfied, the excess lamps are turned off as much as possible to further save energy.

In order to improve the use of electric energy and reduce losses, the north extension line has upgraded the power supply system, adding active filters and reactive power compensation equipment. The functions of these two devices are generally to improve power quality and reduce reactive power loss. .

According to the plan, the North Extension Line Medical School Station, Normal University Station, and Aerospace University Station will be opened for trial operation at the end of the year.
