構成的單相電能表現場校驗儀Traditional energy meter can cause errors under the condition of harmonics due to its structural characters, and at the same time harmonic loads take in foundational power and send out harmonic power. this paper proposes a new way and realizes accuracy and fair energy metering
傳統的電能表在諧波存在下由於自身的結構特性會產生誤差,就此進行分析提出了新的電能計量方法,應用虛擬儀器技術實現了準確、公平、合理的電能計量。The analysis results show that : the frequency characteristic curve assumes the downtrend, so the electrical energy measurement of the induction meter will produce biggish error when the content of the harmonic is big, no matter taking the whole energy as measurement standard or basic wave energy
研究分析結果表明:感應式電能表的誤差頻率特性曲線呈迅速下降趨勢,因此在電能計量中,不管是以全能量為計量標準還是以基波能量為計量標準,當諧波含量較大時對感應式電能表的電能計量將會產生較大的影響。Compared with the induction meter, the electronic meter ' s measurement error is affected diminutively by the change of the frequency, that is to say, the electronic meter has a wide frequency respond characteristic and its error - frequency characteristic curve is flat. therefore, taking the whole energy as measurement standard, the measurement error of electronic meter is less than that of induction meter very much ; while the measurement error of electronic meter is bigger than that of induction meter when taking the basic energy as measurement standard
和感應式電能表相比,電子式電能表的計量誤差受頻率變化影響較小,具有較寬的頻率響應,誤差頻率特性曲線較為平坦,因此,在諧波存在下以全能量為計量標準時,電子式電能表的計量誤差遠遠小於感應式電能表的電能計量誤差,而以基波能量為計量標準時,電子式電能表的計量誤差比感應式電能表的計量誤差大。The company has bettered itself to have an annual production capability of 1200 tons of mpp inner packaging products for industrial, agricultural uses, and 200 special equipment and molds. we have established sound cooperative business relationship with a number of well - known enterprises at home and abroad
