330kV AT power supply traction transformer won the title of “National Key New Product”

In early November, the newly-changed plant was the world’s first 330kV AT-powered traction transformer independently developed and produced by Zhengxi Line. With its superior quality, it was awarded by the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce and the General Administration of Quality Supervision, Inspection and Quarantine, and was awarded This year's "National Key New Product" honorary title.

"National key new products" are jointly issued by the State Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce, and the four ministries and commissions of the General Administration of Quality Supervision, Inspection and Quarantine, and are an important part of the scientific and technological industrialization of the national science and technology planning system. Through guidance and support, encourage enterprises to independently develop new products, promote scientific and technological progress and technological innovation capabilities of enterprises, promote scientific and technological progress and technological innovation capabilities, promote the transformation and industrialization of scientific and technological achievements, and promote the optimization and upgrading of China's industrial structure and product structure adjustment. Enhance the international competitiveness of our products.

The newly-transformed 330kV AT-powered traction transformer won the honorary title of “National Key New Product” and fully affirmed the independent innovation capability of TBEA. It not only fully demonstrated the professional and technical level of the newly-changed plant in the field of railway traction change, but also Shows the important role of TBEA in R&D and promotion of industry development. The 330kV class AT power supply traction transformer is one of the key equipments for the development of Zhengxi High Speed ​​Rail, the first 350km/h passenger dedicated line in China that was newly started to be built in China. It was successfully commissioned in October 2009 and started live operation with its high level. The reliability and smooth running have passed the acceptance of the research team of the Ministry of Railways. The successful development and commissioning of this product has improved the technical capability and popularity of the new products in the auxiliary products of the railway system. It has won the bid for the AT power supply traction of the Beijing-Shanghai high-speed railway, Jingshi, Changji, and Harbin lines for the newly-changed plant in the later period. With a solid foundation, the share of newly-changed plants in the railway market has been greatly improved.

24v DC Worm Gear Motor is the most common used worm gear motor. DC Worm Gear Motor has a low efficiency, so while working, it is necessary to save energy as much as possible.

Dc Worm Gear Motor including a dc motor with a worm gearbox. A worm gearbox means the output shaft is vertical with the dc motor shaft. Connecting the gears with the motor, there is a worm gear. DC Worm Gear Motor has very low efficiency, normally for the first stage, the efficiency will loss at least half. However, dc worm gear motor is widely applied on some products need with self-lock function. Like the automatic range hood in the kitchen, or the roller blind motor.

The dc worm gear motor has the following characteristics:
1. Achieve great speed reduction through high gear ratio. Normally reduce the speed as low as 3-5 rpm.

2. Achieve vertical transform by the worm gear

3. With self-lock function to prevent the back-driving.
