【正文】 he design uses a current transformer switch to control exhaust fan. AC relay and current transformer and switch bination cost design. The principle is that When dryers start, there is current through the current transformer and AC relay coil is energized, and then relay normally open contact closure. The exhaust fan starts to work. This design uses contrast debugging method, the current transformer switch for debugging and overall debugging, after welding debugging, the design of the successful pletion of the design goals. Keywords： Current transformers, AC relay, exhaust fan 目 錄 1. 緒 論 .................................................................................................................. 1 4 研究背景和意義 ............................................................................................ 1 研究背景 ............................................................................................. 1 本課題的研究意義 ............................................................................. 2 2. 系統(tǒng)分析與設(shè)計 ...................................................................................................... 3 電流互感器介紹 ............................................................................................ 5 3. 硬件設(shè)計 .................................................................................................................. 7 整流電路分析和設(shè)計 .................................................................................... 7 驅(qū)動電路 ........................................................................................................ 8 穩(wěn)壓電路 ...................................................................................................... 10 電磁繼電器 .................................................................................................. 10 整機安裝與說明 ...........................................................................................11 4. 實物制作與系統(tǒng)調(diào)試 ............................................................................................ 12 實物制作 ...................................................................................................... 12 系統(tǒng)調(diào)試 ...................................................................................................... 14 電流傳感器調(diào)試 ............................................................................... 14 整機調(diào)試 ........................................................................................... 15 調(diào)試問題 ........................................................................................... 16 5. 結(jié)論 ........................................................................................................................ 17 參 考文獻： ................................................................................................................. 18 致謝 ............................................................................................................................. 19 附錄一： PCB 制作流程圖 .......................................................................................... 20 附錄二：系統(tǒng)電路圖 ............................................................
