According to reports, in 2012, Beijing Metro Company completed the pilot project of 6-station and 2-span LED lighting through the contract energy management mode for the first time. The annual electricity consumption is 900,000 kWh, the power saving rate is 50%, and the power saving effect is good. In order to further utilize the policy advantages, and in line with the “Twelfth Five-Year†energy-saving situation, the company made overall plans and formulated the LED transformation implementation plan for the two lines of Lines 1 and 2.
At present, there are 7 stations that are under construction at the same time. Now we have completed the construction of No.1 Line Dawang Road Station, Yonganli Station, Line 2 Jianguomen Station, Fuchengmen Station and Gulou Street. The entire construction plan is 5 Completed at the end of the month.
The reporter learned that the Beijing Metro Company is a key energy-using enterprise in the city. In 2012, the comprehensive energy consumption was 131,000 tons of standard coal, of which 853 million kWh (80% of the total energy consumption) was the largest electricity consumer in the city.
LVLP series Linear Power Supplies are DC Power Supplies that achieve AC/DC conversion through power frequency transformers and transistor loop control. Compared with switching DC power supplies, linear mode power supplies have higher stability, higher accuracy, and lower output ripple. And the most important, because of the use of the power frequency AC/DC conversion principle, the linear power supply does not have high-frequency radiation interference, and is especially suitable for use in places with restrictions on EMC and EMI.
The LVLP series linear AC - DC power supplies have a wide range of output specifications, the output power ranges from 1KW to 400KW, and the output voltage can reach up to 800VDC, and accept customization.
The whole series DC linear power supply adopts industrial-grade metal chassis, pure copper AC/DC varnished transformer, high-reliability multi-transistor filter loop, ensuring the power supplies can run for a long time at full load with high stability, high accuracy, and ultra-low ripple electronic characteristics, equipped with a complete protection circuit, which can better ensure the reliability of the linear power supply itself and the safety of the customer's load.
The output voltage and current can be adjusted by the 10-turn potentiometer with scale and lock on the front, equipped with 4 1/2-digit high-resolution LED meters for output value reading, and RS communication interface can also be added for remote control and monitoring of linear power supplies.
This series of linear power supplies are mainly used for aging and testing of components such as capacitors, relays, and resistors, and can also be used for experimental testing of electronic components such as thermistors and motors. At present, many well-known capacitor manufacturers, resistor factories and other electronic component production units and scientific colleges and universities and other research and development units use this series of power supplies, and they have all been highly praised.
