電壓表是測量電壓的一種儀器。由永磁體、線圈等構(gòu)成。電壓表是個(gè)相當(dāng)大的電阻器，理想的認(rèn)為是斷路。初中階段實(shí)驗(yàn)室常用的電壓表量程為0~3V和0~15V。 </p> <p> 產(chǎn)品介紹 </p> <p> 電壓表是測量電壓的一種儀器，常用電壓表——伏特表的符號為“V”。 </p> <p> 傳統(tǒng)的指針式電壓表包括一個(gè)靈敏電流計(jì)，在靈敏電流計(jì)里面有一個(gè)永磁體，在電流計(jì)的兩個(gè)接線柱之間串聯(lián)一個(gè)由導(dǎo)線構(gòu)成的線圈，線圈放置在永磁體的磁場中，并通過傳動裝置與表的指針相連。大部分電壓表都分為兩個(gè)量程。電壓表有三個(gè)接線柱，一個(gè)負(fù)接線柱，兩個(gè)正接線柱，電壓表的正極與電路的正極連接，負(fù)極與電路的負(fù)極連接。 </p> <p> 原理 </p> <p> 由于電壓表要與被測電阻并聯(lián)，所以如果直接用靈敏電流計(jì)當(dāng)電壓表用，表中的電流過大，會燒壞電表，這時(shí)需要在電壓表的內(nèi)部電路中串聯(lián)一個(gè)很大的電阻，這樣改造后，當(dāng)電壓表再并聯(lián)在電路中時(shí)，由于電阻的作用，多功能三相電力儀表，多功能三相電力儀表，加在電表兩端的電壓絕大部分都被這個(gè)串聯(lián)的電阻分擔(dān)了，所以通過電表的電流實(shí)際上很小，多功能三相電力儀表，所以就可以正常使用了。 </p> <p> 直流電壓表的符號要在V下加一個(gè)“_”，交流電壓表的符號要再V下加一個(gè)波浪線“~”。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="多功能三相電力儀表"

</p> <p> 誤差來源 </p> <p> （1）測量變換電路引入誤差：電能質(zhì)量分析儀工作時(shí)，電網(wǎng)中電壓、電流信號需分別經(jīng)過電壓互感器 </p> <p> (Potential Transformer，PT)、電流互感器(Current Transformer，CT)送入電能質(zhì)量分析儀，因此PT、CT的比例誤差和相角誤差直接影響到測量結(jié)果的準(zhǔn)確度。當(dāng)電能質(zhì)量分析儀工作在諧波條件下，PT、CT相角誤差發(fā)生改變，對各次諧波電壓、電流的轉(zhuǎn)換比例不一致，輸入ADC的被測信號發(fā)生變形，測量誤差增大。 </p> <p> （2）ADC量化誤差：ADC量化誤差指輸入信號進(jìn)行模數(shù)轉(zhuǎn)換時(shí)，用有限的數(shù)字信號來表示無限精度的模擬信號所造成的誤差。電能質(zhì)量分析儀常采用12位或16位的ADC，且ADC位數(shù)越大，其轉(zhuǎn)換精度越高，量化誤差越小。 </p> <p> （3）其他誤差：包括環(huán)境溫度、相對濕度等因素導(dǎo)致硬件電路產(chǎn)生的誤差，電子器件以及線路老化等因素致使測量結(jié)果產(chǎn)生的誤差。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
