压电式振动测量装置抗电磁干扰改造优化

摘要

通过分析压电式瓦振保护装置的测量原理，总结燃气轮机因强电磁干扰导致瓦振保护误动作而停机的原因，并据此提出了改变信号回路接地点的解决方案，实施后达到了预期效果。%By analyzing the measuring principle of piezoelectric vibration protector, the reasons for gas turbine shutdown were summa-rized of vibration protection malfunction caused by strong electromagnetic interference.According to reasons the solution were put for-ward to change signal circuit ground, after implementing the desired effect was reaching.
