GE IS200TREGH1BDB - Turbine Emergency Trip Terminal Board
stars, based on 0reviews
IS200TREGH1BDB is a turbine emergency trip terminal board developed by GE. It is part of the Mark VI control system Q. The terminal board plays a crucial role in supplying power to the three emergency trip solenoids within the system. TREG is fully controlled by the I0 controller and processes the positive pole of the DC power supply required to operate these solenoids. On the contrary, the terminal board supplements TREG by providing the necessary negative pole for DC power supply to ensure coordinated and balanced distribution of the solenoid.
Trip solenoid valve connection and function
The jumping sound solenoid plays a crucial role in the functionality and safety mechanisms of various systems, especially in emergency shutdown situations, where their connection and operation are essential to ensure seamless power transmission and effective response in emergency situations.
A maximum of three trip solenoids can be interconnected between the TREG (Pulse Relay Electromagnetic Generator) and TRPG (Trip Relay Generator) terminal boards. This arrangement forms an important connection in the emergency trip mechanism of the system, enabling quick and reliable action to be taken when needed.
The connection between the trip solenoid and the terminal board helps to achieve efficient power distribution and control. TREG provides a positive DC power supply, while TRPG provides the corresponding negative pole, establishing the necessary potential for the effective operation of the trip solenoid. This balanced power supply ensures that the trip solenoid valve has appropriate functionality and responsiveness when triggering emergency shutdown or protective measures as needed. By connecting the trip solenoid valve in this way, the system achieves enhanced reliability and redundancy, thereby minimizing the risk of failures or malfunctions during critical operations. This configuration also allows for easier maintenance and troubleshooting, as the connection and operation of each solenoid can be effectively monitored and managed within the entire system framework. The connectivity and functionality of the trip solenoid between TREG and TRPG terminal boards play a critical role in ensuring the safety and reliability of the system
