High-power motor high-voltage soft start technology urgently requires national standards

Organized by China Electrical Appliance Industry Association, an expert seminar on high-voltage motor high-voltage soft start technology co-organized by Dali Electric Co., Ltd. was held at Crowne Plaza Wuzhou Beijing. Fang Xiaoyan, vice president and secretary general of the China Electrical Appliance Industry Association, Zheng Chunbai, deputy director of the Hubei Science and Technology Department, and many well-known experts and professors in the soft start industry attended the meeting.

At the meeting, Professor Wang Xuefan of Huazhong University of Science and Technology, Ren Weihong (General Manager of Inverter Division of Dali Electric Power), Xu Xiaodong (Chief Specialist of U.S. Air Force), Zhu Wei of Xi'an Shaanxi Blower Group Electric Co., Ltd., Chief Engineer of Sinopec SEI Wang Caiyong, and General Manager of Zhongtian Iron & Steel Co., Ltd. Engineers Chen Yuegao and Liuzhou Iron and Steel Chief Engineer Nong Xiaojie and other soft-starting industry experts made special presentations. In addition to this, China Petroleum Ryukyu University, China Metallurgy SADI, Sinosteel Group, China Shenhua, China Metallurgical Capital, China National Light International, The experts of China Textile Industry Institute, Shengu Group, Shanghai Electric Machinery Factory, Donghua Engineering, Hangyang, Shougang, and other electrical experts have conducted in-depth and comprehensive discussions on the existing soft start technology at home and abroad and the future development direction. With the unanimous opinion, the frequency conversion soft start represents the development direction and the highest technical level of the soft start.

Fang Xiaoyan said in his speech that China's soft-start industry generally has low technological content. Due to the relatively late start of China's soft-start industry and other factors, China's soft-start enterprises have not had the ability to fully compete with large multinational companies, and soft-start technology represents soft The direction of development of start-up technology should increase innovation and development and promote the take-off of national brands.

Zheng Chunbai said that China's soft-start technology originated in Fuyang City. It has been more than 20 years since its establishment. The soft-start industry has undergone active technological innovation and innovation, has created tremendous economic benefits, and has promoted the rapid development of national heavy industry and the electric industry. The Hubei provincial government will continue to give greater input to the human, material, and financial resources of the soft start industry, and take full advantage of the large-scale advantages of the soft start industry cluster to fully support the development of the soft start industry.

Through this meeting, the classification of soft start, technical differences and the gap with foreign soft start technology are clarified. Among the three categories of soft start technology: step down, subsidy, and variable frequency, Liyang Diandian Electric has its origins in buck soft start, creating a down soft start, filling the domestic blank of frequency conversion soft start, and the development of China's variable voltage soft start. Make outstanding contributions.
