Product Description
The CPU card PCA-6740 is an intelligent control card designed specifically for the DEH (Digital Electro Hydraulic Control System for Steam Turbines) system, playing a crucial role in power plants. This control card has become a core component of the DEH system due to its excellent performance and stability.
The DEH control system, as an important component of modern large steam turbine generator units, has the characteristics of high responsiveness, high reliability, and long-term safe and stable operation. The CPU card PCA-6740, as the heart of the DEH system, is not only responsible for regulating the speed and power of the steam turbine, but also can automatically perform operations such as speed increase, grid connection, and load increase or decrease based on auxiliary conditions such as the stress of the steam turbine under different working conditions. In addition, it is also responsible for monitoring the operating parameters of steam turbines, generator sets, and main and auxiliary equipment, ensuring their normal operation, and providing alarms and records for abnormal situations.

Product Features:
In terms of power failure, the power module failure rate of CPU card PCA-6740 is relatively high, especially after the power supply has been used for a long time or the lifespan of electronic components has expired. To solve this problem, users should not only choose high-quality CPU cards, but also reasonably configure cabinets to ensure high power redundancy. In addition, regularly checking the output voltage of the power supply and checking the power circuit during maintenance to ensure that there are no wiring problems are also important measures to prevent power module failures. Establishing power management records, managing the lifespan of power supplies, and arranging for the replacement of expired power supplies are also necessary steps. Before replacing the power supply, it is not advisable to wait for a power failure before replacing it to avoid affecting the normal operation of the DEH system.
Applications:
In summary, the CPU card PCA-6740 plays an important role in the DEH system due to its excellent performance and stability. Its high responsiveness, high reliability, and long-term safe and stable operation make it a key component of the DEH system in power plants.
