Overview
The IS200EBRGH2A is an Exciter Bridge Interface Board (EBRG) developed by General Electric (GE) as part of the EX2100e Series used in GE Excitation Control Systems. It is designed to interface the EX2100e control system with the SCR (Silicon Controlled Rectifier) bridge and associated bridge I/O components, ensuring effective control and feedback within the system.
Functional Description
- Bridge Interface: Connects the control system to the SCR (Thyristor Bridge), including related I/O like fan controls, over-temperature detectors, thermistor sensors, and current sensors.
- Control Architecture: Supports both simplex and redundant control configurations through connection to one or two UCSB controllers using HSLA.
- Power Management: Accepts 125 V DC from the station battery and 115/220 V AC from external supplies. The AC is converted to DC using DACA modules, creating a stable DC bus for controllers and I/O boards.
- Mounting and Compatibility: Primarily mounted in the Power Conversion Cabinet, compatible with systems using 77 mm or smaller thyristors (H2 version) and 100 mm thyristors (H1 version).
Key Features
1. Interface and Control
- Enables feedback and control of the bridge, ensuring precise regulation of excitation levels.
- Seamless communication within the system for efficient power management.
2. Mounting Location
- Power Conversion Cabinet: Works alongside PCM, DC circuit contactors, and circuit breakers for optimal functionality.
3. Controller Compatibility
- Not interfaced with Controller C but independently manages bridge firing and control.
4. Power Supply and Integration
- Operates at 125 V DC, powered by the EDIS (primary power source for EX2100e).
- Interfaces with thyristor systems of 42 mm, 52 mm, and 77 mm, offering versatility and adaptability.
5. System Integration
- Facilitates smooth operation and coordination between control systems and power bridges.
- Supports various bridge architectures including simplex, warm backup, and parallel bridge converters.
