Product Details:

ABB 3BHE055094R0002 is the GBU72 grid breaker unit control board for ABB PCS6000 medium voltage wind power converter system. It is responsible for sampling grid voltage, current and breaker contact status signals, executing breaker closing, opening and earthing safety interlock logic inside the converter cabinet. The board can prevent misoperation sequence and avoid short circuit risk on medium voltage power circuits. It communicates with the AC 800PEC main controller through internal rack bus, uploading breaker position status, fault events and diagnostic data to the main control system. The board adopts industrial multi-layer PCB layout with full EMC shielding treatment, built-in surge suppression and signal isolation circuits to withstand high voltage electromagnetic interference inside the converter cabinet and guarantee stable signal sampling during long-term operation in wind farm environments.

It adopts standard cabinet backplane mounting structure, supporting convenient removal and replacement during breaker fault inspection and periodic maintenance. The interlock threshold and protection logic can be set via PCS6000 engineering software to satisfy different grid safety specifications. Built-in self-diagnosis function can detect signal loss, power supply abnormality and internal circuit failure, triggering safe lockout state and alarm output once fault occurs. Every spare board will pass signal sampling test, interlock logic verification and rack compatibility check before shipment to ensure stable cooperation with original PCS6000 converter hardware. It is widely stocked as replacement spare parts for grid breaker safety control of medium voltage wind converters.

Industry Applications: Applied in petrochemical auxiliary skids, gas flow control systems, boiler closed-loop control rooms and water treatment facilities for conventional analog signal acquisition and valve regulating output.
