style="text-indent:25px">相位測量技能是電子技能中進(jìn)行信息檢測的重要方法,在現(xiàn)代科學(xué)技能中占有無關(guān)宏旨的效果和地位。相位差測試儀是工業(yè)領(lǐng)域中是常常用到的一般測量東西，比如在電力體系中電網(wǎng)并網(wǎng)合閘時,需求兩電網(wǎng)的電信號相同，這就需求精確的測量兩工頻信號之間的相位差。更有測量兩列同頻信號的相位差在研討網(wǎng)絡(luò)、體系的頻率特性中具有重要意義。相位測量的方法許多，典型的傳統(tǒng)方法是經(jīng)過顯示器觀測，這種方法過錯較大，讀數(shù)不方便。為此，我們規(guī)劃了一種數(shù)字相位差測量儀，實現(xiàn)了兩列信號相位差的主動測量及數(shù)顯。相位差測試儀應(yīng)用于電力線路、變電所的相位校驗和相序校驗，具有核相、測相序、驗電等功用。具有很強(qiáng)的抗干擾性，習(xí)氣各種電磁場干擾場合。被測高電壓相位信號由采集器取出，經(jīng)過處理后直接發(fā)射出去。由接納器接納并進(jìn)行相位比較，對核相后的效果定性。</p><p style="text-indent:25px">所謂移相是指兩種同頻的信號，以其中的一路為參考，另一路相?對于該參考作超前或滯后的移動，即稱為是相位的移動。兩路信號的?相位不同，便存在相位差，簡稱相差。若我們將一個信號周期看作是?360，則相差的范圍就在0°～360°。：兩個同頻信號之間的移相，?是電子行業(yè)繼電保護(hù)領(lǐng)域中模擬、分析問題的一個重要手段，利用移?相原理可以制作校驗各種有關(guān)相位的儀器儀表、繼電保護(hù)裝置的信號?源。因此，移相技術(shù)有著特別廣的實用價值。我們知道，將參考信號整?形為方波信號，并以此信號為基準(zhǔn)，延時產(chǎn)生另一個同頻的方波信號，?再通過波形變換電路將方波信號還原成正弦波信號。偏光片吸收軸角度、偏振片偏振方向、波片快軸方向。</p><div
