4. Applications in Industrial Automation
The 5461-769 plays a critical role in industrial automation and power generation environments:
- Steam Turbine Control: Manages startup, speed regulation, and extraction/admission control of steam turbines.
- Power Generation Systems: Used in power plants to regulate turbine-driven generators for stable frequency and load management.
- Compressor and Pump Drive Control: Ensures precise speed control for turbine-driven compressors and pumps.
- Process Industry Applications: Applied in chemical plants, refineries, and other industries requiring precise turbine operation.
- Safety and Protection Functions: Includes overspeed protection, critical speed avoidance, actuator travel limits, and event logging for operational safety.
Working voltage:
The main power supply of the fire linkage controller generally uses 220V AC voltage; The backup power source is a DC power source, powered by batteries,
with a supply voltage of generally 24-32V. When powered by AC, the grid voltage is between 85% and 110% of the rated voltage (220V).
When the frequency fluctuates within the range of 50Hz ± 1Hz, the fire linkage controller should be able to work normally. The voltage stability and load stability of its
output DC voltage shall not exceed 5%.
3) Electromagnetic compatibility:
The electromagnetic compatibility of the fire linkage controller refers to the adaptability and stability of the fire linkage controller under electromagnetic interference
environmental conditions, which should comply with the relevant provisions of the current national standard GB16806 “Fire Linkage Control System”.
4) Security performance:
The safety performance of the fire linkage controller refers to the electrical safety performance of the fire linkage controller in use, which should comply with the relevant
provisions of the national standard GB16806 “Fire Linkage Control System”.
3、 Engineering application
The engineering design, construction, and acceptance of the fire linkage controller shall comply with the relevant provisions of the current national standards GB50116 and
GB50166. In terms of selection and use, cabinet, desktop, and wall mounted fire linkage controllers should be selected according to the characteristics of the usage location,
system scale, and user needs. Wall mounted fire linkage controllers are commonly used in small and medium-sized fire linkage control systems; For large-scale or ultra large
scale fire linkage control systems, cabinet or desktop fire linkage controllers should be selected. Corresponding forms of fire linkage controllers should
also be selected based on the usage environment conditions and certain special requirements. Explosion proof fire linkage controllers should be selected for environments
that are prone to explosion hazards; Marine fire linkage controllers should be selected for marine use.
