SLANVERT main control system and redundant high-voltage frequency converters help a mine in Southeast Asia achieve efficient operations

  Quality goes global! We SLANVERT main control system and redundant high-voltage frequency converters help a mine in Southeast Asia achieve efficient operations.

  In the main shaft control room of a state-owned coal mine in a Southeast Asian country, as the new system started up smoothly for the first time, the on-site technical manager watched the operating data and sincerely remarked, "Your products and services are trustworthy." This renovation project utilized the SBHQ series four-quadrant high-voltage variable frequency drive equipment provided by SLANVERT, successfully completing the upgrade of the drive system.

  Mine hoists are core equipment in coal mining operations; their stable operation is essential for both transporting personnel and materials in and out of the mine. The choice of drive system directly impacts the mine's production efficiency, operational safety, and overall costs.
  The original hoisting motor used a rotor series resistance starting method, which faced numerous problems over the long term: high current surges during the starting process, which not only significantly impacted the power grid but also increased equipment wear; poor speed control stability, affecting hoisting accuracy; consistently high energy consumption, resulting in serious power waste; and a high equipment failure rate and heavy maintenance workload, severely restricting the efficient operation of the mine.

  Considering the core requirements of high reliability and high stability for mine hoists, it was SLANVERT would adopt the SBHQ four-quadrant high-voltage frequency converter specifically designed for hoisting machines, and configure a dual main control system redundancy solution. This "dual-core drive" approach offers higher reliability and became the key to overcoming these challenges.
  Dual-Controller Redundancy: Each inverter integrates two independent control systems, enabling millisecond-level switching. This eliminates the risk of production downtime due to system failures, significantly improving the reliability of the entire system.
   High Control Accuracy: Equipped with high-performance vector control technology, it achieves high torque output at low frequencies, with minimal torque ripple and fast dynamic response, fully meeting the control requirements of hoists under complex load conditions.
  Strong Environmental Adaptability: The entire unit is specifically designed for the harsh, humid, and dusty environment of mines, with reinforced designs in circuit protection, sealing, and heat dissipation to ensure long-term stable operation of the equipment.
  After using SLANVERT products, customers have achieved significant benefits in many aspects at their facilities:
Stable equipment operation: Smooth starting and stopping without impact, significantly improved speed control accuracy, significantly reduced mechanical wear, and effectively extended equipment lifespan.

  Significant energy savings: Four-quadrant operation allows braking energy to be fed back into the power grid, achieving efficient energy utilization and significantly reducing electricity costs. Reduced maintenance costs:  Equipment reliability is greatly improved, and the failure rate is significantly reduced. This reduces maintenance workload and the costs associated with spare parts replacement and downtime for repairs.
  The successful commissioning of the high-voltage four-quadrant dual-master control variable frequency drive system has not only precisely addressed the customer's practical operational pain points but also further validated the high reliability and strong adaptability of SLANVERT variable frequency drive solutions in the mining engineering field. In the future, SLANVERT will continue to focus on the industry, providing safer and more efficient industrial automation system solutions, empowering global mining customers, and contributing to the high-quality development of intelligent mining processes!
