| 摘 要： | 某电厂机组调试间发生一次六大风机振动信号全部瞬间跳变导致六大风机跳闸引起机组MFT，经检查是由于风机振动控制拒的接地不合理引起，处理好接地后振动信号正常后未发生跳变情况，文章分析了产生干扰信号的原因及抑制方法。

| Abstract: | One power plant unit MFT happened because of six-fan vibration signals a moment jump. The trip is due to the unreasonable grounding of the fan vibration control cabinet. Vibration signal is normal after handling the grounding. This article analyzes the reasons of the signal disturbing and its suppression method. |
