China's First Commercial Refurbished Hybrid Locomotive is Delivered from CRRC Ziyang
After the refurbishment, the locomotive is equipped with lithium iron phosphate battery & diesel gen-set as the power source, and the traction force is basically the same as the original GK1 series locomotive, so it can replace the original locomotive operation.
Meanwhile, the locomotive power battery can be directly connected to 380V industrial power supply for charging, and the locomotive fuel saving is more than 90%. Due to the use of hybrid technology, lithium battery is the main component in locomotive operation, so the comprehensive emission index of the entire locomotive is better than Tier3, and the locomotive noise is significantly reduced.
As a leading enterprise in the development of hybrid locomotives in China, CRRC Ziyang successfully developed the first 1000kW hybrid locomotive in China, which won the "Energy Saving and Emission Reduction Technology Invention Award" in China, and took the lead in launching the world's most powerful hybrid locomotive HXN6 and obtained the type license & manufacture license issued by the National Railway Administration.
While improving the hybrid locomotive technology, CRRC Ziyang takes concrete actions to fulfill the requirements of “Speeding up the obsolescence of old railway locomotives, and encouraging the development of energy saving & environmental protection transportations” proposed by the State Council and China Railway, and actively explores the use of hybrid technology to refurbish old locomotives. The old locomotives can be refurbished and reconstructed to realize hybrid traction by making full use of the original locomotive equipment and less refurbishment cost input, so as to achieve the effects of environmental protection, energy saving, noise reduction and operation cost reduction.
In June of 2020, CRRC Ziyang took the lead in realizing the refurbishment of old Dongfanghong 5 shunting locomotive to the hybrid locomotive. After more than one year of operation, the advanced, reliable, energy-saving and environmental performance of the locomotive has been well verified.
It is reported that CRRC Ziyang has built the hybrid technology upgrade and refurbishment platform of traditional diesel-hydraulic locomotives such as Dongfanghong 5 and GK series, which can satisfy the refurbishment for about 25% of the domestic old railway locomotives. At the same time, it can also provide services for overseas users to upgrade and refurbish the hybrid technology.
