The TZYW-50000kW 4P/10kV positive pressure ventilation explosion-proof synchronous motor and RMVC-60000kVA/10kV ultra-large capacity high voltage inverter developed by Wolong electric Drive won the “Global Chemical Equipment’s first set of Cooperative Research and Development Contribution Award” by Zhongjing Petrochemical Group, the world’s largest propane-dehydrogenation device with an annual output of 1 million tons. It is also the highest level award awarded by Zhongjing Petrochemical Group. Zheng Yanwen, vice president of Wolong Electric Drive and president of Central Research Institute, led the team to participate in the project production celebration and the 2024 Global Customer Conference, and spoke on behalf of Wolong Electric Drive as an excellent supplier.
The transformation of steam to electricity is not only the development needs of the national dual-carbon economy and the 3060 national policy, but also the overall operation efficiency of the field system can be significantly improved. Wolong Electric Drive is the only enterprise in China that can provide high voltage motor, inverter and system solutions as a whole. The complete set of products of “50000kW/10KV large brushless synchronous explosion-proof motor and 60000kVA large capacity high voltage inverter” developed for Zhongjing Petrochemical Group has reached the international advanced level of comprehensive performance.
Among them, Wolong Electric Nanyang explosion-proof Group under Wolong Electric Drive developed 50000kW synchronous explosion-proof motor, which has the advantages of low vibration, high efficiency and low noise. The 60000kVA ultra-large capacity inverter developed by the transmission division of Wolong Electric Drive has been identified by the results of China Machinery Federation, and has the advantages of strong disturbance resistance, fast heat dissipation, low system circulation loss and high machine efficiency. After identification, this super power water-cooled inverter has reached the international .
The whole field of domestic substitution, the overall technology is internationally advanced
This kind of motor is widely used in metallurgy, petrochemical, chemical and other places, mainly used in PTA, blast furnace fan, steam to power, air separation device, propane dehydrogenation device, can achieve domestic substitution in the whole field. At present, orders have been placed in petroleum, chemical industry, metallurgy, air separation, aviation and other fields. The inverter can meet the control needs of high-power equipment driving and starting, and can be adapted to high-pressure asynchronous machine and high-pressure synchronous machine, and can be widely used in LNG, chemical industry, natural gas transmission, air separation, air energy storage and other important load fields.
The key technology research has overcome the low vibration, high power density design, high efficiency design and high reliability design and manufacturing technology of large motor, motor has high efficiency, low vibration, low noise characteristics, the overall technology has reached the international advanced level of similar products.
Green, low carbon, safe, high reliability
The motor efficiency has reached the international advanced level, and the motor price is far lower than that of foreign motors, which not only saves the one-time input cost for customers, but also saves the electricity cost in the later period, which reduces the maintenance cost in the later period.
The high power density design of the motor can save the input cost of the user’s civil construction, plant, crane and the input cost of the on-site circulating water station and oil station, and reduce the maintenance cost of the later overhaul.
By ensuring the small leakage of the motor, the nitrogen or instrument air required to maintain the micro positive pressure inside the motor can be reduced, the air source usage can be reduced, and the use cost can be reduced.
The motor has a protection rating of IP55 and can be used directly outdoors. The high protection level can also ensure the stability of operation and extend the maintenance cycle, help the internal motor is not polluted by external materials, and reduce user maintenance costs.
High reliability design and manufacturing technology to ensure the long-term reliable operation of the motor, to protect the failure of major equipment caused by the huge cost of immeasurable.
Complete sets of design, supply, service more worry and time saving
The localization of motor and inverter can not only minimize procurement costs, shorten the manufacturing cycle, but also greatly improve the service response speed, which can greatly avoid the safe and reliable operation of the project because of the manufacturing cycle and service speed.
Motor, inverter complete sets of design, supply, can ensure that the motor, inverter parameters fully match, to provide users with safe, reliable, efficient solutions, to minimize system maintenance costs.
