IS200TRPGH2BDD GE MKVI, TERM BD TRIP PRIMARY

Description:

Functional Overview
The IS200TRPGH2BDD, a Primary Gas Turbine Trip Output Board manufactured by GE, is an integral part of the Mark VI control system. Under the control of the I/O controller, this board is engineered to interface with Electrical Trip Devices (ETDs) via magnetic relays, thereby ensuring the system's reliability and safety.
Interaction with ETDs
The TRPG features nine magnetic relays divided into three voting circuits, each connected to a dedicated trip solenoid. These solenoids, collectively referred to as ETDs, play a vital role in initiating trips or shutdowns when certain conditions or faults are detected within the system. The three voting circuits offer redundancy, enhancing the reliability of the trip initiation process.
Coordination with TREG
To establish a robust connection with ETDs, the TRPG works in tandem with the TREG. The combined functions of the TRPG and TREG ensure the establishment of both primary and emergency interfaces with the ETDs. This dual-sided approach adds an additional layer of reliability to the trip initiation system, enabling effective and prompt responses to critical situations.
Flame Detection Feature
Beyond its primary role in trip initiation, the TRPG is also equipped to handle inputs from eight Geiger Mueller flame detectors used in gas turbine applications. This flame detection capability bolsters the system's safety features by providing real-time monitoring of the presence or absence of flames within the turbine environment. Swift and accurate flame detection is essential for preventing potential hazards and ensuring the safe operation of the gas turbine.
Compatibility
The H2A version of the TRPG is designed for simplex applications, with a configuration where each trip solenoid is associated with one relay. This streamlined setup is suitable for scenarios where redundancy is not a critical requirement, offering a cost-effective solution for applications with straightforward operational demands.
Installation Details
Trip Solenoids Connection: The three trip solenoids, crucial for initiating shutdowns, are directly connected to the first I/O terminal block. This direct and secure connection between the TRPG and the trip solenoids minimizes potential points of failure and optimizes system reliability.
Flame Detectors Integration: In systems that include flame detectors, these devices are connected to the second terminal block. The wiring for flame detectors, if utilized, is carefully organized to provide a reliable interface with the terminal board. This step is vital for enabling real-time flame detection capabilities in gas turbine applications.
Power Supply for Flame Detectors: The power supply for the flame detectors is provided through dedicated wiring to connectors J3, J4, and J5. This ensures a stable and independent power source for the flame detection system, enhancing the overall safety and reliability of the installation.
Power Distribution: The terminal board manages power distribution for critical components in the system. Specifically, the 125 V DC power required for the operation of the trip solenoids is routed through connector J1. This dedicated power connection is essential for the proper functioning of the trip solenoids, enabling them to respond promptly to potential faults or critical conditions.
Board Power Transfer: Connector J2 facilitates the transfer of power to the board. This ensures that the TREG, working in conjunction with the TRPG, receives the necessary power supply for its operation. The coordination between these two boards is crucial for maintaining a reliable interface with the ETDs and effectively responding to system contingencies.
Compliance and Safety Measures: During installation, it is crucial to adhere to industry standards and guidelines to ensure the safety and compliance of the entire system. All wiring connections should be secured and verified, and power distribution must align with the specified voltage requirements for each component. Regular testing and verification procedures should be implemented post-installation to confirm the integrity of the connections and the proper functioning of the TRPG terminal board in conjunction with associated components.
