alt="LCD數(shù)顯電力儀表分類,電力儀表" src="https://tyunfile.71360.com/WaterMark/UploadFile/keaton/637237707544560547/2308852.jpg"></div><p> 頻率表是指測(cè)量頻率的機(jī)械式指示電表。頻率表種類很多，有電動(dòng)系、鐵磁電動(dòng)系和屬于整流式的變換器式頻率表等。 </p> <p> 原理<span style="display:none;"></span> </p> <p> 鐵磁電動(dòng)系頻率表的測(cè)量機(jī)構(gòu)與電路如圖。帶有鐵心的固定線圈與電感器L、電容器C組成的串聯(lián)諧振電路,通常被調(diào)整在標(biāo)尺的中間頻率(例如50赫)時(shí)諧振?？蓜?dòng)部分由兩個(gè)線圈組成，其中動(dòng)圈1與電容器C1串聯(lián)后與諧振電路并聯(lián)。接通電源時(shí)，可動(dòng)部分所受轉(zhuǎn)動(dòng)力,I、I1分別為固定線圈及動(dòng)圈1中電流,θ為兩電流相量間夾角，K為系數(shù)。動(dòng)圈2與電阻器R2、電感器L2構(gòu)成閉合回路。當(dāng)可動(dòng)部分指針偏離標(biāo)尺中間位置α角時(shí)，動(dòng)圈2將受到一個(gè)與偏轉(zhuǎn)角α成正比、并使指針?lè)祷刂虚g位置的反抗力矩。當(dāng)被測(cè)頻率等于標(biāo)尺中間頻率時(shí),諧振電路發(fā)生諧振,這時(shí)固定線圈中的電流與動(dòng)圈1中電流相量間夾角θ=90°,因而轉(zhuǎn)動(dòng)力矩M=0。于是可動(dòng)部分在動(dòng)圈2力矩的作用下，使指針指在標(biāo)尺的中間頻率（例如50赫）的刻度上。當(dāng)被測(cè)頻率偏離中間頻率時(shí)，諧振條件被破壞，轉(zhuǎn)動(dòng)力矩不再為零，可動(dòng)部分發(fā)生偏轉(zhuǎn)，直到轉(zhuǎn)動(dòng)力矩與反抗力矩平衡時(shí)為止，可動(dòng)部分將停在與被測(cè)頻率對(duì)應(yīng)的新位置上。改變串聯(lián)諧振電路的參數(shù)，可以獲得不同的頻率量程。
