An issue with instrument fluctuations
Thread Content
The temperature sensor at the top of Tower B fluctuated a few times before returning to normal, while the temperature sensor at the top of Tower A showed no fluctuations. After the tops of Towers A and B were connected, the flow passed through the heat exchanger and condenser before reaching the turbine unit. The speed of the turbine unit also fluctuated a few times, in line with the curve of Tower B. Here’s the question: why didn’t Tower A show any fluctuations? The temperature points and rotational speed are stored in different cards, with no connection between them. There is no logical connection in the configuration. All other instruments, including those indicating the status of the engine unit, are normal. The temperature at Tower B was also normal during on-site inspection. I’m completely baffled by this.
Is there a poor connection, or are there any accidental interference sources?
"The temperature sensor at the top of Tower B fluctuated a few times before returning to normal, while the temperature sensor at the top of Tower A showed no fluctuations. \"It is clearly due to Tower B; the main focus is on analyzing the possible reasons for the temperature fluctuations at the top of Tower B.\"
There was no fluctuation in the liquid level at the top of Tower B, and no fluctuations in the temperatures in the middle and lower sections.
The key is whether the rate of temperature fluctuation is within the acceptable range; if it is too fast, interference or other causes of failure need to be considered； If the speed is within the normal range, the cause should be sought in the possibility of parameter fluctuations; after all, turbine units also experience curve fluctuations, but factors related to the power supply need to be ruled out.
