2-25AMP,AC240V,PDA1系列PCB固態繼電器unionelecom,本人認為，啟動時變頻器輸出電壓和頻率是逐漸上升的，電機被水淋濕后，會造成輸出電流的變化率很高，從而引起直流回路過壓。(2)控制輥道電機的AEGMaxiverter-170/380變頻器出現速度反饋值大于速度設定值經觀察發現:a)在軋鋼過程中不存在這種情況，當鋼離開輥道后，才出現這種情況;b)當速度反饋值大于速度設定值時，直流回路電壓為額定電壓的125%，超過115%的極限設定值;c)變頻器的進線電壓已超過上限;在軋鋼過程中，該變頻器控制的輥道電機將升速，當鋼離開輥道后輥道電機速度降至原來的速度，因這臺變頻器未裝設制動裝置，減速時是通過電壓調節器限制制動電流以保持直流回路電壓不超過115%的極限設定值(缺省值)。
