The GE IS200ERDDH1A EX2100 Exciter Regulator Dynamics Discharge Board is a key component of the EX2100 excitation control system. It plays a critical role in executing dynamic discharge during the operation of the excitation system. When the system needs to quickly cut off the excitation current, this board can respond rapidly, safely releasing the energy in the excitation winding through a specific circuit. This prevents equipment damage caused by energy accumulation, effectively protecting the excitation system and related devices. Adopting advanced circuit design, it features high reliability and stability, capable of adapting to complex and changeable industrial operating environments. It provides a solid guarantee for the stable operation of generators, contributing to efficient and safe power production.
Functional Purpose: Mainly used to control the output voltage and current of the excitation transformer to stabilize the voltage and current of the generator set. It also provides bridge feedback functions for monitoring the output field, DC link voltage, shunt output current, IGBT gate drive status, and bridge temperature.
Control Modes: Supports excitation control and power factor regulation.
Accuracy Parameters: Voltage accuracy is ±0.1%, and current accuracy is ±0.2%.
Communication Interfaces: Supports RS232, RS485, Ethernet, etc.
Power Requirements: 24V DC.
Physical Characteristics: Dimensions are 483 mm × 320 mm × 210 mm, and the weight is approximately 20 kg.
Working Environment: The operating temperature range is -40°C to 85°C, with a protection class of IP65, suitable for harsh industrial environments.
Design Features: Adopts a modular design for easy installation and maintenance, reducing maintenance costs and time. It supports both simplex and redundant operation modes, ensuring high reliability.
Installation Methods: In simplex mode, it is installed in the ERBP backplane to control the K3 charging relay; in redundant mode, two units are required, one installed in the ERBP backplane and the other in the ERRB backplane to control the K41 field discharge relay.
