Modernization of the bucket-wheel excavator’s on-board power supply system
Smooth load control and impact-free switching enabled by modern asynchronous electric motors.
Optimized energy consumption (reduction by 10–25%) and lower operational costs through a digital control system, elimination of seasonal adjustments, and use of reliable equipment.
High-level safety ensured by intelligent equipment monitoring (temperature, vibration diagnostics), an automated operating mode, and an emergency protection system.
The implementation of asynchronous motors (ADKR) with frequency regulation across all mechanisms enhances system efficiency and performance. The use of frequency converters with torque control on key components ensures smooth mechanical characteristics in gear mechanisms, while maintaining high machine dynamics for optimal operation.
The high efficiency of the system significantly reduces specific energy consumption, leading to cost savings and improved sustainability. Additionally, the integration of low-voltage LAPP cables, designed to withstand UV radiation and oil exposure, guarantees a service life of over 20 years. Similar cable systems have been operating at SRSK for more than 25 years without replacement, proving their durability and reliability in demanding conditions.
