At this meeting, the representative of Kunming Steel specially introduced the successful experience of using the high-voltage inverter developed by Dongfang Hitachi (Chengdu) Electronic Control Equipment Co., Ltd. instead of the hydraulic coupling to adjust the converter dust removal fan of the enterprise and its acquisition. The remarkable energy saving effect is a great inspiration for the conference delegates.
Since 2003, Kunming Steel's No. 2 Steelmaking Plant and No. 3 Steelmaking Plant have selected 9 high-voltage inverters developed by Dongfang Hitachi (Chengdu) Electronic Control Equipment Co., Ltd. instead of the original fluid couplings. The above-mentioned significant power saving effect, but also achieved objective economic benefits, recovered the investment cost within 2-3 years.
At present, Dongfang Hitachi (Chengdu) Electronic Control Equipment Co., Ltd. has signed more than 60 (6KV, 10KV) high-voltage high-power inverters with steel enterprises such as Kunming Steel, Chenggang, Panzhihua Iron and Steel, Handan Iron and Steel, Maanshan Iron and Steel Co., Ltd. Supply contract.
The meeting believes that high-voltage and high-power motors are one of the main battlefields for power-saving. High-voltage and high-power inverters are the main means to improve the power-saving efficiency of high-voltage motors. This product can be widely used in steel, wind turbines, pumps and winches and other equipment, and will achieve better power saving effect. It is hoped that this power-saving product of high-voltage inverter can attract enough attention and promote the use of all relevant steel companies.
