style="text-indent:25px">位差測試儀是工業(yè)領域中是經(jīng)常用到的一般測量工具，比如在電力系統(tǒng)中電網(wǎng)并網(wǎng)合閘時，需要兩電網(wǎng)的電信號相同，這就需要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究網(wǎng)絡、系統(tǒng)的頻率特性中具備重要意義。相位測量的方法很多，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，我們設計了一種數(shù)字相位差測量儀，實現(xiàn)了兩列信號相位差的自動測量及數(shù)顯。近年來，隨著科學技術的迅速發(fā)展，很多測量儀逐漸向“智能儀器”和“自動測試系統(tǒng)”發(fā)展，這使得儀器的使用比較簡單，功能越越多。江蘇光學膜相位差測量儀技術指導相位差測試儀的數(shù)據(jù)輸出：電腦連接。</p><div

相位差測試儀應用于電力線路、變電所的相位校驗和相序校驗，具有核相、測相序、驗電等功能。具備很強的抗干擾性，適應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。由接收器接收并進行相位比較，對核相后的結果定性。因本產(chǎn)品是無線傳輸，真正達到安全可靠、快速準確，適應各種核相場合。 </p> <p> <br /> </p> <p> <br /> </p> <p> 相位測量技術的研究由來已久，早年的研究和應用是在數(shù)學的矢量分析和物理學的圓周運動以及振動學方面，隨之在電力部門、機械部門、航空航天、地質勘探、海底資源等方面也相應得到重視和發(fā)展。隨著電子技術和計算機技術的發(fā)展，相位測量技術得到了迅速的發(fā)展，目前相位測量技術已較完善，測量方法及理論也比較成熟，相位測量儀器已系列化和商品化。 </p> <p> <br

style="text-indent:25px">滯后的相位值都為π的一半，或者說90°.在計算電路電流有效值時，電容電流超前90，電感落后90，可用矢量正交分解加合.加在晶體管放大器基極上的交流電壓和從集電極輸出的交流電壓，這兩者的相位差正好等于180°.這種情況叫做反相位，或者叫做反相.正弦量正交（90°）和反相（180°）都是特殊的相位差.目前，國內相位差測量儀生產(chǎn)廠家或研究單位明顯存在著技術老化問題，其采用的器件、方法和技術與技術先進國家有較大的的差距。而**近發(fā)展的先進的計算機技術、電子技術等卻由技術、資金、管理等方面的原因未能應用于相位測量技術，因此國內相位測量的水平與國外水平有著相當大的差距。同時，隨著**和科教等領域的發(fā)展，迫切需要高精度高性能的相位測量系統(tǒng)，而且在一些特殊工程領域，還需要測量儀器具備其它特殊功能。由此可見，為縮小這些差距，對高精度相位測量算法的研究和相位測量系統(tǒng)的設計刻不容緩。本文介紹的是一套較完整的高精度相位差測量儀，提高相位及頻率參數(shù)的測量精度，并擴展測相系統(tǒng)功能，由移相網(wǎng)絡模塊、相位差測量模塊及頻率測量模塊三大部分構成，其系統(tǒng)功能主要是進行相位差測量及頻率和幅度測量。相位差測試儀：拉伸膜相位差測試儀。</p><div
