摘要
地震来临时,为能及时进行核电站核地震应急紧急处置,需要稳定可靠的地震触发技术实现核岛控堆。地震触发功能实现主要采用加速度传感器AC-73和触发器进行组合来实现核岛控堆功能,通过对加速度传感器输出信号进行实时检测,设计频带1 Hz^10 Hz带通滤波电路实现信号抗干扰,采用迟滞比较器等抗扰动措施保证装置的稳定性核可靠性,经过一个月拷机测试,未出现误触发动作,该技术能稳定可靠的实现地震触发报警,具有实际应用的价值。
In order to deal with the nuclear earthquake emergency in time,the stable and reliable seismic trigger technology is needed to realize the nuclear island control reactor.The seismic trigger function is mainly realized by the combination of acceleration sensor AC-73 and trigger to realize the nuclear island control reactor function,and the output signal of the acceleration sensor is detected in real time.The frequency band 1 Hz^10 Hz band-pass filter circuit is designed to realize signal anti-jamming.Anti-disturbance measures such as hysteresis comparator are used to ensure the stability kernel reliability of the device.This technique can realize the earthquake trigger alarm stably and value of application.
