GE DS2020BRCAG3 Brake Control Assembly

الوصف

The GE DS2020BRCAG3 is a Dynamic Brake Control Assembly Module used in the General Electric Mark V Series of Turbine Control Systems and GE Drive Control Systems.

Its full functional name is often described as a 15 Amps Brake Control Assembly.

🛑 Core Function: Dynamic Braking Control

The primary function of the DS2020BRCAG3 is to manage the Dynamic Braking System for large motor-driven machinery, such as a turbine’s rotor or associated equipment in a power generation system. Dynamic braking is a method used to rapidly and efficiently stop or decelerate a rotating machine by converting its kinetic energy into thermal energy for dissipation.

The module performs several critical safety and control functions:

• Braking Activation & Release: It receives signals from the turbine’s main control unit (the control logic) to precisely activate and release the mechanical or electrical braking system for smooth and controlled deceleration.
• Deceleration Control: It ensures that the motor-driven equipment decelerates at a controlled rate, preventing abrupt stops that could cause mechanical stress or damage.
• Energy Dissipation: It controls the process of converting the motor’s kinetic energy into heat, which is then safely dissipated, typically through dynamic braking resistors.
• Overspeed Protection: The module is integrated with the turbine’s safety mechanisms and will automatically engage the brakes if the turbine’s speed exceeds predetermined safe limits, which is a critical safety feature.
• Current Regulation: It manages the current supplied to the brake actuator, handling up to 15 Amps of current, and includes protection features against overcurrent and thermal stress to ensure system reliability.
