Baoding Transformer pull the worlds highest speed railway
This morning, by the Baoding Transformer Co., Ltd. production of railway traction transformers, traction power supply auto transformers and other equipment, the success of the Beijing-Shanghai high-speed rail through Zaozhuang to Bengbu section of the maximum speed between the pilot test, the train speed of 486.1 kilometers, set a world rail operations top speed record.
This is the second September 28, Shanghai-Hangzhou high-speed rail test run after a record speed of 416.6 km, Baoding, China Railway high-speed rail to accept the transformer again broke the world rail speed up the test of trial operation. Pilot section of Beijing-Shanghai high-speed rail all the equipment Baoding railway transformer autotransformer produced products, this high-speed runs through Beijing, Tianjin, Hebei, Shandong, Anhui, Jiangsu, Shanghai, 7 provinces and cities, connecting the Bohai Sea and the Yangtze River Delta two major economic area, the line from Beijing South Railway Station to Shanghai Hongqiao Station, the new rail link 1318 km, is the world s first built the longest line length, the highest technical standards, the fastest high-speed rail.
Baoding railway transformer manufacturing company developed special railway transformers and other products has reached more than 30 series, 180 varieties, used stone too, co-Wu, Nanjing, Hangzhou and other passenger lines and Beijing and Tianjin, Wuhan-Guangzhou high-speed rail line , export to Iran, Thailand, Pakistan, Albania, more than 10 countries and regions.
UHV AC outlet device authentication through
UHV AC outlet device authentication through
13, UHV transformers and reactors Used 1000 kV standard outlet devices successfully tested in Baoding, Hebei verified.
Excellent indicator of the outlet device, stable performance, achieved in the operating impulse voltage, lightning
impulse voltage and power frequency withstand voltage of partial discharge-free design expectations. The outlet device
successfully developed to accelerate the subsequent UHV construction progress, special high-voltage transformer
protection and the quality of reactor stability is important.
In transformers and reactors, the 1000 kV to 1000 kV outlet device to bear high pressure from the coil leads, through
the box and connected with the role of the casing. The device requires a high voltage tolerance within a small scale, to
ensure that the electric, magnetic, thermal and mechanical stress under the action of many other long-term reliable
operation, the structural design, quality materials and manufacturing processes demanding. In China s first UHV in the
construction of 1000 kV supply outlet device, seriously affected the progress of the project.
To this end, the State Grid Corporation organized to promote the standardization of 1000 kV outlet device design and
manufacturing. Switzerland, Weidmann for the company in conjunction with domestic manufacturer s standard design, the
company experts to conduct a comprehensive feasibility studies, carry out the checking and review of proposed inspection
and testing requirements, and material preparation, production and installation tests, etc. part of a comprehensive
management and control.
After more than eight months fighting, standardized 1000 kV outlet device developed and Tianwei change security
companies UHV AC pilot demonstration project on a standby transformer produced by the test. Compared with the original
outlet devices, new product performance, reasonable structure, the production cycle is short, easy to install, greatly
easing the follow-up duration of the project UHV pressure.
How to choose a home improvement must Daixinban
How to Select Daixinban?
● Daixinban in the Home of Use:
Blockboard, commonly known as Daixinban inline. Daixinban board by the middle of two pieces of wood glued together splicing pressure. Wooden furniture and packages can do, and door pockets, heating cover, Chuanglian, with its waterproof performance is better than particleboard and MDF. Into 3,5,9 Daixinban determined by the thickness of plates, we can withstand the pressure and intensity of use, the thicker the higher the price.
● How to identify the quality of Daixinban:
Seeing it in the selection of the internal timber, should not be too broken, the gap between the wood around the 3mm Blockboard appropriate.
A look at the weight, two to see prices. In fact, the heavier Daixinban, its quality, the worse. Because of the weight, the more that use this board Zamu. This makes up with Hardwood Daixinban simply nail into a nail, it can not be used. In addition, the prices are low Daixinban, their quality will certainly be poor. The gap is not large, is the use of substandard wood.
● selection of quality Daixinban:
A manufacturer to see if the product is regular. To view the manufacturer’s trademark, manufacturer address, and security signs.
Second, product testing report, see the formaldehyde emission per liter is less than and equal to 1.5 mg. Manufacturers generally have a formal test report, the detection of formaldehyde values should be as low as possible.
● How to reduce the rational use of formaldehyde pollution Daixinban:
Generally about 100 square meters room with Daixinban not over 20, but also consider other interior decoration, if you use too much will cause excessive formaldehyde in the indoor environment. Especially do not do on the floor below in Daixinban liner, so as to avoid indoor air formaldehyde poisoning.
