In November 2010, Leader Huafu Company successfully signed two sets of 8000kW/10kV (equivalent to 10000kVA/10kV) high-voltage frequency converters in a steel plant in Yunnan. Previously, the user had investigated several high-voltage inverter manufacturers at home and abroad. Finally, Leader Huafu has conquered users with high-power stable operation performance and high-reliability product quality, thus also creating the highest power sales of domestic high-voltage inverters.
As early as in 2007, the first domestically produced 5600kW/10kV speed sensorless vector control high-voltage frequency converter of the domestically produced maximum power level was successfully put into production operation in an iron and steel group company in Hebei Province. Its operating symbol Li Dehua Fu's product technology has taken a new step, changing the market structure of high-power high-voltage inverter equipment of more than 5000kW monopolized by a few foreign companies.
After more than one year of successful operation of this equipment, Leader Huafu succeeded in developing a 7500kW/10kV ultra-high-power inverter and passed many rigorous tests. He soon signed a contract with a steel plant in Shandong and produced it in November 2008. Commissioning is complete. The 7500kW/10kV high-voltage frequency converter has been put into operation on the large-scale wind turbine of this steel plant. It has been operating normally and has good energy-saving effect. It has created enormous economic benefits for customers.
From 2009 to 2010, a certain southwest iron and steel group successively put into operation 4 high-voltage frequency inverters with 6500kW/10kV high-capacity AC motor frequency conversion and industrial frequency bi-directional undisturbed synchronous switching technology. In 2010, the 7000kW/11kV high-power high-voltage inverter produced by Leadwards Huafu was successfully put into operation in a well-known Indian company. The current operating conditions are stable. This is also the second time that the company has successfully cooperated with Leadward.
The ultra-high-power inverter produced by Leader Huafu Co., Ltd. adopts the frequency conversion and industrial frequency bi-directional undisturbed synchronous switching technology of domestic leading high-capacity motors, which can realize the soft start of a single inverter with multiple large synchronous or asynchronous motors. After the output voltage of the inverter is synchronized with the grid voltage to complete the amplitude, frequency, and phase, the frequency converter and the power grid double circuit supply power to the load motor, and then the frequency conversion or power frequency loop is cut off as needed. With this technology, bi-directional undisturbed frequency conversion of the load motor can be realized.
Lead Huafu 10000kVA/10kV frequency conversion speed control equipment is currently the domestic maximum power level inverter, and its operation will fill the gap in the domestic technology, and further established the domestic high-voltage inverter high-power application of the leading position. From the 5600kW/10kV to 7500kW/10kV, to 8000kW/10kV successfully put into operation, Leader Huafu not only lead the high-voltage frequency conversion market, but also in the high-power applications are also steadily climbing, until recently, Leader Huafu high pressure Inverter sales have exceeded 4,300 sets, creating industrial performance standards all the way, and constantly innovating ahead!
