Serving as the "neural center" of high-voltage systems, this module enables precise control and real-time status monitoring of equipment like high-voltage circuit breakers, disconnectors, and transformers, ensuring the safe, stable, and efficient operation of high-voltage systems.
It adopts a reinforced insulation design and redundant architecture, has passed international safety certifications for high-voltage equipment, and can work reliably for a long time in harsh environments such as strong electromagnetic interference and high humidity. It is an ideal solution for the automated control of large-scale industrial high-voltage systems.

Core Features and Advantages

1. Dedicated Control Capability for High-Voltage Systems

• Wide Voltage Level Adaptation: Supports the full range of 3kV-35kV high-voltage systems and is compatible with high-voltage equipment of different capacities (10MVA-500MVA), enabling flexible deployment without hardware adjustments.
• High-Precision Signal Acquisition: Equipped with a built-in 24-bit high-precision ADC converter, it supports signal acquisition of high-voltage side voltage (0-50kV) and current (0-2000A), with a measurement accuracy of ±0.05% FS, meeting the metering-level requirements of power systems.
• Fast Control Response: Powered by a dual-core 32-bit industrial processor (200 MIPS), the control cycle can be as low as 1ms, ensuring rapid response to high-voltage faults (e.g., short-circuit protection action time < 20ms).
• Professional High-Voltage Algorithms: Built-in dedicated control logic for high-voltage equipment (such as circuit breaker opening/closing sequence control and transformer on-load tap-changer algorithm), complying with power industry standards including IEC 61850 and GB/T 14285.

2. Enhanced Safety and Insulation Design

• Multi-Level Insulation Protection: Adopts a reinforced insulation structure with a creepage distance > 40mm, electrical clearance > 25mm, and insulation withstand voltage > 50kV (for 1 minute), meeting the DL/T 478 standard for high-voltage equipment control.
• Comprehensive Fault Protection:
• Hardware-Level: Overvoltage (60kV), overcurrent (3000A), and arc protection, with a response time < 1μs;
• Software-Level: Operation interlocking for high-voltage equipment, self-diagnosis of status, and protection against communication anomalies;
• System-Level: Links with high-voltage protection devices to achieve "control-protection" integration.
• EMC Optimization: Passes the EN 61000-6-2/4 EMC test for high-voltage environments, featuring strong anti-interference capability and maintaining signal stability during high-voltage switch operations.

3. High-Reliability Redundant Architecture

• Full-System Redundant Configuration: Supports 1+1 hot redundancy for control boards, dual power backup, and communication link redundancy, with a switching time < 20ms. It meets the "zero downtime" operation requirement of high-voltage systems, with a Mean Time Between Failures (MTBF) > 1,200,000 hours.
• Wide-Temperature Stable Operation: Uses military-grade components (-40℃~+85℃), and the PCB board is coated with special three-proof paint (salt spray resistant, mildew proof), adapting to the installation environment of outdoor high-voltage cabinets (IP54 protection level).
• Vibration and Shock Resistance: Complies with IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock) standards, and can be installed in high-vibration locations such as substations and rolling mills.

4. Smart Grid Compatibility and Communication

• Grid-Level Communication Interfaces:
• 2 channels of Gigabit industrial Ethernet (supporting IEC 61850-8-1 MMS and GOOSE messages), enabling seamless connection with substation automation systems;
• 1 channel of Profibus DP (for connecting local intelligent devices);
• 1 channel of IRIG-B code interface (time synchronization accuracy ±1μs), meeting the requirements of Sequence of Events (SOE) recording in power systems.
• Data Recording and Analysis: Built-in 64MB data storage, which can record key operating data for more than 1 year (sampling interval 10ms). It supports waveform recording for 10 seconds before and 5 seconds after a fault, facilitating accident tracing and analysis.
• Remote Monitoring Support: Compatible with the ABB Ability™ Power Cloud Platform, supporting remote parameter configuration, status monitoring, and fault diagnosis, reducing operation and maintenance costs.
