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，比如在電力系統(tǒng)中電網(wǎng)并網(wǎng)合閘時(shí)，需求兩電網(wǎng)的電信號(hào)相同,這就需求準(zhǔn)確的測量兩工頻信號(hào)之間的相位差。更有測量兩列同頻信號(hào)的相位差在研討網(wǎng)絡(luò)、系統(tǒng)的頻率特性中具備重要意義。相位測量的方法許多，典型的.傳統(tǒng)方法是通過顯示器觀測，這種方法誤差較大，讀數(shù)不方便。為此，我們規(guī)劃了-種數(shù)字相位差測量儀,完成了兩列信號(hào)相位差的自動(dòng)測量及數(shù)顯。近年來，跟著科學(xué)技術(shù)的迅速開展，許多測量儀逐步向“智能儀器”和“自動(dòng)測試系統(tǒng)”開展，這使得儀器的運(yùn)用比較簡單,功能越越多。 </p> <p> 相位差測試儀應(yīng)用于電力線路、變電所的相位校驗(yàn)和相序校驗(yàn)，具有核相、測相序、驗(yàn)電等功能。具備很強(qiáng)的抗煩擾性，習(xí)氣各種電磁場煩擾場合。被測高電壓相位信號(hào)由采集器取出，通過處理后直接發(fā)射出去。由接收器接收并進(jìn)行相位比較,對(duì)核相后的成果定性。因本產(chǎn)品是無線傳輸，真實(shí)到達(dá)安全可靠、快速準(zhǔn)確，習(xí)氣各種核相場合。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">相位常應(yīng)用在科學(xué)領(lǐng)域，如數(shù)學(xué)、物理學(xué)等。例如：在函數(shù)y=Acos(ωx+φ)中，ωx+φ稱為相位。在astrolog32中點(diǎn)擊ALTIFT+A可以顯示相位設(shè)定菜單。在交流電中，相位是反映交流電任何時(shí)刻的狀態(tài)的物理量。交流電的大小和方向是隨時(shí)間變化的。比如正弦交流電流，它的公式是i=Isin2πft。i是交流電流的瞬時(shí)值，I是交流電流的比較大值，f是交流電的頻率，t是時(shí)間。隨著時(shí)間的推移，交流電流可以從零變到比較大值，從** 大值變到零，又從零變到負(fù)的** 大值，從負(fù)的比較大值變到零。在三角函數(shù)中2πft相當(dāng)于弧度，它反映了交流電任何時(shí)刻所處的狀態(tài)，是在增大還是在減小，是正的還是負(fù)的等等。因此把2πft叫做相位，或者叫做相。高精度軸角度相位差測量儀相位差(0 20000nm)。</p><div style="width:100%;text-align:

位差的單位是度或弧度，正、負(fù)號(hào)表示搶先或滯后聯(lián)系。待測相位差的正弦電量的頻率規(guī)模很廣，因此選用的丈量辦法和儀器一般隨頻率的高低來挑選。常用的辦法是直接法和間接法。間接法一般選用三電壓表法。 -般要求兩電壓信號(hào)有一-公共點(diǎn)(設(shè)為a點(diǎn))，當(dāng)分別測出兩信號(hào)電壓Uab、Uca,
