During the operation of turbines, speed and impactor status are two crucial monitoring parameters. The XJZC-03A/Q turbine speed and impactor monitor, specifically designed for rotating machinery such as turbines, successfully integrates speed monitoring with impactor status monitoring, providing solid support for the safe operation of equipment. This article will delve into how the XJZC-03A/Q monitor achieves impactor status monitoring.

I. Function of the Impactor and Emergency Trip Device

Firstly, it’s essential to understand the role of the impactor and emergency trip device in turbines. When the turbine speed reaches or exceeds the set emergency trip value, the emergency trip device activates, and its internal impactor ejects due to centrifugal force, triggering an emergency shutdown mechanism to prevent equipment damage or accidents. However, due to the typically concealed installation location of the emergency trip device, it’s impossible to directly observe the ejection and retraction status of the impactor, necessitating specialized monitoring equipment for supervision.

II. Working Principle of the XJZC-03A/Q Monitor

The XJZC-03A/Q monitor receives signals from magnetoresistive or Hall effect sensors to perceive turbine speed. These sensors can accurately detect minute changes in the turbine shaft and convert them into electrical signals sent to the monitor. The high-performance embedded processor inside the monitor processes these signals to obtain accurate speed values and displays them in real-time on the screen.

In terms of impactor status monitoring, the XJZC-03A/Q monitor employs special signal reception and processing technology. When the impactor ejects due to turbine overspeed, it triggers a switch signal (or impactor action signal), which is received and recorded by the monitor. Similarly, when the impactor retracts, a corresponding signal is also triggered, and the monitor records and saves it. Thus, the monitor can monitor the status of the impactor in real-time and provide detailed impactor action records when needed.

III. Steps for Achieving Impactor Status Monitoring

1. Signal Reception: The XJZC-03A/Q monitor receives impactor action signals from the emergency trip device through its internal sensor interface. These signals can be switch signals or high-level signals, depending on the configuration of the monitor and the type of emergency trip device.
2. Signal Processing: The high-performance embedded processor inside the monitor processes the received impactor action signals, converts them into recognizable data formats, and stores them in internal memory.
3. Data Display and Recording: The processed impactor status information is displayed in real-time on the monitor’s screen and also recorded in internal memory for subsequent analysis and review.
4. Alarm and Protection: When the impactor action signal triggers an alarm condition (e.g., turbine overspeed causing impactor ejection), the monitor immediately issues an alarm signal and cuts off the power to the monitored equipment or takes other protective measures through relay output, etc., to prevent equipment damage or accidents.

The XJZC-03A/Q turbine speed and impactor monitor achieves real-time monitoring and recording of impactor status by receiving and processing impactor action signals from the emergency trip device. This function not only enhances the safe operation level of turbines but also provides vital data support for equipment maintenance and fault analysis.
