China's first high-power passenger electric locomotive completed the test run

As of August 17, HXD1D (Harmony 1D Electric Locomotive), the first high-power AC-driven passenger electric locomotive in China numbered 0001, had been in trial operation for a full year and accumulated a total safe operation of 320,000 kilometers, equivalent to 8 laps around the equator. This indicates that the new locomotive has completed the commissioning test required by the railway system. In the future, it is expected to become the main locomotive for traction of passenger railways in the country and be used for the upgrading of quasi-high-speed trains such as Z and T prefixes.

HXD1D locomotive was independently developed by China South Locomotive Zhuzhou Electric Locomotive Co., Ltd. (CSR) and its maximum traction power is 7200KW, with a maximum capacity of 3000 passengers and a continuous operation speed of up to 160km / h, with good accelerating performance and acceleration from 0 To 160 km only takes 5 minutes. As a leading model of China's power-concentrated quasi-high-speed passenger electric locomotive that changes from direct current to alternating current, this locomotive has filled the gap in the field of high-power delivery rapid passenger electric locomotive in our country and has been implemented between common express passenger car and high- A good connection.

On August 17, 2012, the HXD1D-0001 locomotive wearing the "China Red" armor drove out from Wuchang South Depot and formally started the on-line operation assessment. The news, attracted a lot of "train fans" of the extended stay. The results of one year "trial run" on the Beijing-Guangzhou line from Beijing to Wuhan, from Wuhan to Shenzhen and from Wuhan to Shanghai show that the model has been able to adapt to the complicated and changeable terrain environment in China. The climate of -40 ℃ to 40 ℃ Conditions, as well as wind, rain, snow, salt spray, dust and other complex conditions, most of the territory can carry passengers.

According to the introduction of CSR CSR Zhujiang Machine Technology experts, this locomotive is designed based on the large domestic scale and complex operating conditions. Based on the "Shaoshan" series of DC locomotives, it is the first time in China to apply high-power AC drive technology to passenger locomotives . The car is not only equipped with advanced 6A monitoring system, enabling walking, brake, fire, power supply and other real-time monitoring, but also loaded with South Korean independent research and development of machine DK2 brake system, with stand-alone self-test, fault diagnosis, Data recording and storage functions, breaking the monopoly of foreign technology, the brake process can also be converted into electrical energy back to the power grid.
