HD8000 Series Medium Voltage Engineering Drive: Powering Efficiency
for Demanding Industrial
Product Overview
The HD8000 Series Medium Voltage Engineering Drive is a
high-performance, modular drive system designed for heavy-duty
industrial applications requiring robust power delivery and precise
control. Engineered with an advanced AC-DC-AC topology, it supports
both single-drive and multi-drive configurations, including shared
DC bus architectures, making it ideal for industries such as
metallurgy, oil and gas, mining, and rail transportation. With a
maximum single-unit capacity of 102MVA, the drive accommodates a
wide voltage range (1900V to 10kV grid-side input; 660V to 3300V
motor-side output), ensuring compatibility with global power
standards and seamless integration into diverse operational
environments.
Key Features
High-Power Precision Control Equipped with vector control and direct torque control (DTC)
algorithms, the HD8000 Series delivers precise speed and torque
regulation for motors under extreme loads. Its multi-quadrant
operation capability enables efficient energy regeneration during
braking, reducing reliance on external resistors.
Advanced Cooling and Durability Featuring an IP54-rated water-cooling system, the drive maintains
optimal performance in harsh conditions, including high ambient
temperatures and dusty environments. The system supports continuous
overload operation at 110% rated current and short-term overloads
up to 120% for 60 seconds, ensuring reliability in critical
processes.
Harmonic Suppression and Grid Stability Utilizing multi-pulse rectification and active PWM rectifier
technology, the drive minimizes harmonic distortion (THDi <3%),
enhancing grid power quality and compliance with IEC 61000-3-12
standards.
Intuitive Human-Machine Interface (HMI) A 15.6-inch industrial-grade touchscreen provides real-time
monitoring of operational parameters, fault diagnostics, and
configuration adjustments. Preloaded application-specific templates
streamline setup for common industrial workflows.
Unique Advantages
Modular Scalability The drive’s modular design allows rapid component replacement and
capacity expansion. Critical subsystems—such as power cells,
control units, and cooling modules—are independently serviceable,
minimizing downtime during maintenance or upgrades.
Comprehensive Safety Protocols Certified to CE, IEC, and ATEX standards, the drive incorporates
multi-layer protection mechanisms, including
overvoltage/undervoltage shutdown, phase-loss detection, and
thermal overload alerts. An integrated water-flow monitoring system
prevents cooling failures.
Smart Predictive Maintenance Embedded AI algorithms analyze historical and real-time data to
predict component wear, such as capacitor degradation or fan
lifespan, enabling proactive maintenance planning. Remote access
via encrypted cloud platforms facilitates centralized management of
distributed assets.
