Introduction
The urgent need for high-power equipment upgrades; medium-voltage variable frequency drive solutions address industry pain points. Heavy industries such as oil and gas, chemical, mining, and metallurgy rely heavily on high-power equipment ranging from thousands to tens of thousands of kilowatts. However, these devices generally face problems such as starting current surges impacting the power grid, significant losses from unplanned downtime, and difficulty in adjusting load fluctuations. Traditional solutions suffer from high energy consumption and poor adaptability, failing to meet the demands of digital transformation. Schneider Electric's Altivar 1200 series medium-voltage variable frequency drives (including 1200C/1200C-S) offer adaptable solutions for high-power equipment thanks to their high reliability, high performance, and customized solutions. Their value has been proven in mining, steel, and new energy sectors, making them a key choice for upgrading industrial high-power equipment.
I. Comprehensive Reliability Design, Laying a Solid Foundation for Stable Equipment Operation
The Altivar 1200 series achieves reliability upgrades from individual units to the entire machine. The core power unit utilizes long-life metal film capacitors, extending their service life to approximately 15 years, significantly reducing the risk of capacitor failure. Improved component integration and circuit stability allow it to withstand complex electromagnetic interference and voltage fluctuations, enabling continuous, trouble-free operation in scenarios such as mining water pumps and steel blast furnace blowers. Addressing the continuous production requirements of high-power equipment, this series supports single-unit drive and multi-unit parallel solutions, providing 50%/100% redundancy configuration, fault bypass, and seamless switching. It even reserves expansion interfaces, ensuring stable operation now while allowing for future capacity increases. Simultaneously, optimized design shortens construction cycles, reduces maintenance materials and training costs, and optimizes the entire lifecycle cost.

II. Customized Solutions Capabilities, Precisely Matching Differentiated Industry Needs
Based on extensive application experience, Schneider Electric tailors solutions for different industries and scenarios: In the retrofitting of sintering main exhaust fans in the steel industry, addressing the compatibility challenges of 11000kVA high-power equipment, a module pre-charging function was equipped to reduce inrush current and achieve seamless grid connection; in a compressor retrofitting project at a chemical plant in Central China, an innovative "dual main drive + redundant backup" solution was launched, using only three frequency converters to achieve redundancy protection for two main units, saving on equipment procurement and machine room expansion costs, and enabling fully automatic and seamless switching; in a new energy LNG project, a "one-to-one" speed control solution was designed to meet the customer's single-unit configuration requirements, achieving the first application of a 14000kW air-cooled single unit, verifying the product's adaptability in the new energy field.
III. Adapting to New Energy Trends, Empowering Green and Efficient Industrial Upgrades
Against the backdrop of rapid development in the new energy industry, the Altivar 1200 series precisely addresses the speed control and soft-start needs of high-power equipment. In a zero-carbon hydrogen-ammonia project, Schneider Electric configured a variable frequency drive solution for the chemical compressor, paired with an inrush current suppression cabinet to control the starting inrush current to within 1.2 times the rated current. This achieves soft starting of the motor, reducing the impact on the power grid and equipment, while precisely adjusting the compressor speed to match the gas consumption demand. This perfectly meets the process and energy-saving requirements of the new energy project, providing technical support for the green and low-carbon transformation of industry.
