The CJY 7T electric locomotive is suitable for large mines. Its characteristics include a short wheelbase, good body rigidity, good buffering performance, low mechanical wear, step-less speed regulation, no arc on/off, high reliability, low failure rate, fast current protection, and energy saving. The speed regulation method is variable frequency speed regulation, using AC variable frequency motor traction, with low maintenance costs, wide speed regulation range, and simple and safe operation. The locomotive is equipped with three braking methods: mechanical, electrical, and air.
Xiangtan southern electric locomotive manufacturing co., LTD . Is mine, construction of tunnel with narrow rail electric locomotive professional manufacturers, is located in the beautiful xiangjiang river, electric locomotive originate land-hunan xiangtan. The company was founded in the early 1980s, it has been 30 years of history, has focused on production explosion-proof special type battery electric locomotive, industrial and mining wiring type electric locomotive and its accessories. The company covers an area of 50 mu, with modern production workshop more than fifteen thousand square meters, test center two and a full set of professional test platform and track, all kinds of processing equipment, testing equipment more than 120 sets, the staff of morethan 150 people, including senior technical titles has staff more than 50 people, research and development, manufacturing andafter-sales condition complete. The company is China coal products group company approved for the national coal industry electromechanical equipment sentinel production enterprises; 2004 through the national ISO9001:2000 quality certification, and in 2009 by the China quality certification center according to ISO9001:2008 standard through in version of the authentication. The company produces the battery electric locomotive product series and wiring type electric locomotive 2 big series 51 products have passed the relevant state department approval to issue "mining product safety sign certificate" and "mine explosion-proof authentication"; The company produces "the Ann" series of industrial and mining electric locomotive was awarded China famous electric locomotive top ten brand". In recent years, the company has been rated as "hunan integrity unit", "observing contracts and keep promise in unit", " quality is stable qualified unit".
At present, the company produces the flameproof special type storage battery electrical locomotive and industrial and mining wiring type electric locomotive speed control system is used to design the second generation IGBT intelligent controller and frequency conversion speed controller, its key technology has been declared national patent. The intelligent controller for the original resistance speed controller and the first generation of chopping speed regulation controller defect and the insufficiency, has stable performance, is not easy to burn out electronic components, energy saving significanty, the use of safe and reliable, simple operation, low failure rate. Using this kind of controller of frequency control of motor speed electric locomotive has failuer rate bottom, downhill easy control, climbing force is big, energy saving is remarkable, and the small amount of maintenance etc, and into the market by the users trust and praise. We adhering to the "thought determine the way out, character casting products" enterprise idea, in the spirit of "first-class products, reasonable price, satisfactory service" business purpose, with the most reliable quality of products, the most efficient considerate service to meet customer needs. We believe that "because focus , so professional", more believe that your choice will cast our common brilliant.
