Innovators' Night •2023
On the evening of November 29, the "Innovator's Night •2023" Sichuan Patent Award special program was held at Sichuan Radio and Television Station.
"A locomotive multi-module variable frequency AC auxiliary system and its implementation method" of CRRC Ziyang won the second prize of Sichuan patent.
This is a new achievement made by CRRC Ziyang in the field of locomotive AC transmission technology!
This patent proposes for the first time that the auxiliary AC transmission system of diesel locomotive can adopt a multi-module control mode, which greatly improves the reliability of locomotive operation and leads the development trend of locomotive auxiliary system.
At present, most of the company's electric drive diesel locomotives, diesel-electric hybrid locomotives, and pure electric locomotive auxiliary systems adopt this method.
CRRC Ziyang independently developed China's first high-end diesel locomotive exported to developed countries, the first meter-gauge locomotive exported to Argentina in China, the first commercial HXN6 hybrid locomotive in China, and the locomotive exported to Pakistan and Thailand by the company have successfully adopted this patented technology and achieved good economic benefits.
(CRRC Ziyang Co., Ltd exports second-generation high-end diesel locomotives to Australia)
"Innovation-driven development", CRRC Ziyang will continue to strengthen the leading role of scientific and technological innovation, vigorously promote core technology research, and strive to contribute more to the development and progress of China's locomotives.
