style="text-indent:25px">“諧波”一詞起源于聲學(xué)。電力系統(tǒng)的諧波問(wèn)題早在20世紀(jì)20年代和30年代就引起了人們的注意。當(dāng)時(shí)在德國(guó)，由于使用靜止汞弧變流器而造成了電壓、電流波形的畸變。1945年J.C.Read發(fā)表的有關(guān)變流器諧波的論文是早期有關(guān)諧波研究的經(jīng)典論文。諧波的定義諧波 (harmonic wave)可以分為電壓諧波和電流諧波，從嚴(yán)格的意義來(lái)講，諧波是指電流中所含有的頻率為基波的整數(shù)倍的電量，一般是指對(duì)周期性的非正弦電量進(jìn)行傅里葉級(jí)數(shù)分解，其余大于基波頻率的電流產(chǎn)生的電量。</p><p

style="text-indent:25px">從廣義上講，由于交流電網(wǎng)有效分量為工頻單一頻率，因此任何與工頻頻率不同的成分都可以稱(chēng)之為諧波，這時(shí)“諧波”這個(gè)詞的意義已經(jīng)變得與原意有些不符。正是因?yàn)閺V義的諧波概念，才有了“分?jǐn)?shù)諧波”、“間諧波”、“次諧波”等等說(shuō)法。諧波是正弦波，每個(gè)諧波都具有不同的頻率，幅度與相角。諧波頻率是基波頻率的整倍數(shù)，根據(jù)法國(guó)數(shù)學(xué)家傅立葉(M．Fourier)分析原理證明，任何重復(fù)的波形都可以分解為含有基波頻率和一系列為基波倍數(shù)的諧波的正弦波分量。諧波保護(hù)器初次使用時(shí)要檢查有沒(méi)有異樣。蘇州門(mén)衛(wèi)諧波保護(hù)器安裝</p><p
