Overview

The ABB RK638005-BA Control Board is a specialized intelligent module used in UniGear medium-voltage switchgear and GIS/AIS high-voltage systems. Known as part of the RLDA 103 series, this unit serves as the logic and control core for switchgear automation. It supports motorized operation of breakers, disconnectors, and grounding switches, while enforcing mechanical and electrical interlocks to prevent unsafe operations.

Moreover, the RK638005-BA facilitates real-time status monitoring and signal feedback to SCADA systems. It collects data such as switch positions, energy storage status, and control power anomalies, enabling operators to remotely manage switchgear assets with enhanced safety and precision. Its modular design supports hot-swapping and redundancy, making it ideal for mission-critical applications.

Technical Data

Typical Applications

• Substation Automation: The RK638005-BA enables remote control and monitoring of switchgear in substations, supporting “three remote” operations (remote control, remote signaling, remote measurement).

• Renewable Energy Integration: Used in wind and solar step-up stations to manage high-voltage switchgear safely.

• Industrial Power Distribution: Drives switchgear in steel, chemical, and heavy manufacturing facilities where operational safety is critical.

• Legacy System Upgrades: Ideal for retrofitting traditional switchgear with smart control capabilities and SCADA integration.

For instance, utilities have deployed RK638005-BA in UniSec and SafePlus switchgear systems to enhance automation and reduce manual intervention. Additionally, its dual interlock logic helps meet “five prevention” safety standards, including the prevention of load disconnector operation and grounding switch misoperation.
