Siemens Perfect Harmony GH180 Solution
SINAMICS PERFECT HARMONY GH180 solutions introduction
The SINAMICS PERFECT HARMONY GH180 is a series of cells linked together to create the medium voltage power output of the drive system. The design features an integrated transformer and the ability to scale the drive for a wide range of voltage and output power. The drive offers increased availability due to its modular design and ability to bypass any one cell during operation. The quality of the output voltage is so close to perfect sine-wave shape that motors of literally any type – old or new, low-speed or high-speed – can be operated without any additional stress.

- "We should promote the construction of a beautiful China, adhere to the integrated protection and systematic governance of mountains, rivers, forests, fields, lakes, grass and sand, coordinate industrial restructuring, pollution control, ecological protection, and respond to climate change, coordinate carbon reduction, pollution reduction, green expansion, and growth, and promote ecological priority, conservation and intensive, green and low-carbon development“
More and more iron and steel plants are actively practicing the business philosophy of green manufacturing plants, and creating a green development road with their own characteristics.
Siemens and a metallurgical equipment manufacturer assisted the flue gas treatment project of a steel plant by providing key frequency conversion drive equipment in its core equipment, dust removal fan. The reliability requirements that the annual average operation time of the dedusting fan is not less than 300 days and the annual downtime is less than 100 hours are guaranteed.
From the beginning of the project, together with Siemens, we have provided customers with a professional GH180 perfect harmony solution. The proprietary neutral point offset patent technology provided by Siemens GH180 products and the market share of nearly 10000 domestic equipment have effectively verified its higher reliability and availability.
This leading metallurgical equipment manufacturing enterprise has been committed to the research and development of new technologies and processes for industrial flue gas pollution control and the introduction and transformation of international advanced environmental protection scientific and technological achievements. The self-developed pure dry desulfurization, denitration and dedusting integrated clean emission technology and low-temperature denitration technology have the technical performance of "flue gas conditioning, desulfurization, fluoride removal, dedusting, low-temperature denitration" integration. The chimney exhaust has no smoke tail and does not require chimney anti-corrosion No desulfurization wastewater, no secondary pollution of aerosol and stable operation have established its leading position in the field of flue gas treatment. Its dedusting fan is the core equipment to realize the low-temperature denitration technology in the whole process link, which is critical to the whole process control.
Comprehensive advantages of Siemens SINAMICS GH180 series inverter:-Improve productivity-Lower maintenance and operation costs-Outstanding reliability-Precise process control-Intuitive man-machine interface
SINAMICS perfect harmony GH180 frequency converter is applied in various industrial industries such as electric power, petroleum, chemical industry, mining, metallurgy and municipal administration. Tiantuo Sifang helps customers significantly improve productivity, enhance energy utilization and reduce operating costs.
