Function Features
- Rapid and Reliable Trip Protection
The board monitors key operating parameters of turbines in real time. Once it detects abnormal conditions such as overspeed, overcurrent, or undervoltage, its built-in 21 plug-in relays can quickly trigger the trip mechanism to cut off the power supply of the turbine. This rapid response capability ensures the turbine shuts down safely before serious failures occur, maximizing the protection of equipment and on-site personnel.
- Convenient Maintenance with Modular Design
The plug-in design of the relays and standardized connectors simplifies on-site maintenance. When a single relay malfunctions, maintenance personnel only need to remove the fixing metal strap to pull out the faulty relay for replacement, without replacing the entire board. This modular structure reduces maintenance time and significantly lowers maintenance costs for enterprises.
- Self-test and Intuitive Status Monitoring
The board is integrated with a self-test function that continuously diagnoses its own circuit and relay status during operation. It also comes with easy-to-read LED indicator lights. These indicators clearly display the operating status of each relay and the overall board. Operators can directly observe the indicator lights to quickly identify faults, enabling timely troubleshooting and ensuring the board is always in a standby state.
- Customizable Protection Logic
The board supports user-defined trip strategies. According to different turbine models and industrial application requirements, technicians can program the relays to set multiple trip points and adjust protection logic. This customization allows the board to adapt to various turbine operating conditions and industrial process requirements, enhancing its versatility across different scenarios.
Application Scenarios
- Gas Turbine Safety Protection in Oil and Gas Refineries
Oil and gas refineries widely use gas turbines to drive large compressors and transfer pumps. This board integrates into the Mark V control systems of these turbines. It monitors parameters such as the operating speed of the turbines and the pressure of the gas transmission pipeline. When abnormal pressure or speed fluctuations occur, it triggers an immediate trip to avoid leaks or explosions in flammable gas environments.
- Steam Turbine Trip Control in Thermal Power Plants
It is applied to the Mark V control systems of steam turbines in thermal power plants. It connects to temperature sensors in steam pipelines and pressure sensors in turbine casings. It monitors steam temperature and turbine internal pressure in real time. When parameters exceed safe thresholds, it quickly shuts down the steam intake valve and triggers the turbine to trip, ensuring stable power generation operations and protecting the turbine from damage caused by excessive temperature or pressure.
- Wind Turbine Overspeed Protection in Wind Power Farms
In wind power farms equipped with Mark V control systems, this board is used to protect wind turbines. It connects to wind speed sensors and turbine speed sensors. When extreme weather causes wind speeds to exceed the safe operating range and the turbine overspeeds, the board immediately activates the trip mechanism to stop the rotation of the blades, preventing blade breakage or tower collapse due to overspeed.
- Auxiliary Turbine Protection in Metallurgical Plants
Metallurgical plants use turbines to power blast furnace blowers and smelting auxiliary equipment. This board is integrated into the supporting Mark V control systems. It monitors the current of the blower motors and the temperature of the turbine bearings. When overload or overheating occurs, it triggers a trip to shut down the related equipment, ensuring the continuity of the smelting process and avoiding damage to high-value production equipment.
- Legacy System Maintenance in Chemical Plants
Many chemical plants still operate legacy Mark V control systems to drive turbines for reactors and material mixing equipment. This board serves as an essential spare part for these systems. When the original trip board fails and leads to delayed protection responses or invalid trips, replacing it with the DS200TCTGG1AFF can quickly restore the safety protection function of the turbine control system, minimizing production interruptions and economic losses.
