1、對變壓器的影響諧波電壓可使變壓器的磁滯及渦流損耗增加，使絕緣材料承受的電氣應(yīng)力增大，而諧波電流使變壓器的銅耗增加，這種危害對換流變壓尤為嚴重，因為交流濾波器通常裝在交流側(cè)，諧波電流仍通過換流變壓器，濾波器對它不起作用。 2、對電容器和電纜的影響在諧波電壓作用下，使電容器產(chǎn)生額外的功率損耗。電容器對供電系統(tǒng)其它部分產(chǎn)生串聯(lián)、并聯(lián)諧振，可能發(fā)生危險的過電壓及過電流，這往往引起電容器熔絲熔斷或使電容器損壞。在諧波電壓作用下，電纜的介質(zhì)損耗也增加。使電力電纜絕緣損壞，電纜發(fā)生單相接地故障的次數(shù)明顯增加。浙江高性能諧波保護器裝置價格諧波保護器功能特點：結(jié)構(gòu)設(shè)計有效，路線簡易，安裝調(diào)節(jié)便捷。</p><div

style="text-indent:25px">電力系統(tǒng)中，諧波保護指什么？我國電力系統(tǒng)的頻率為50Hz,，即每秒50周。由于電機制造、變壓器鐵芯等多種因素，系統(tǒng)內(nèi)會產(chǎn)生3次、5次、多次諧波。諧波是統(tǒng)稱。諧波是有害的。諧波：諧波(harmonic wavelength)，是一個數(shù)學(xué)或物理學(xué)概念，是指周期函數(shù)或周期性的波形中能用常數(shù)、與原函數(shù)的較小正周期相同的正弦函數(shù)和余弦函數(shù)的線性組合表達的部分。從嚴格的意義來講，諧波是指電流中所含有的頻率為基波的整數(shù)倍的電量，一般是指對周期性的非正弦電量進行傅里葉級數(shù)分解，其余大于基波頻率的電流產(chǎn)生的電量。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之為諧波，這時“諧波”這個詞的的意義已經(jīng)變得與原意有些不符。正是因為廣義的諧波概念，才有了“分數(shù)諧波”、“間諧波”、“次諧波”等等說法。</p><p

style="text-indent:25px">“諧波”一詞起源于聲學(xué)。電力系統(tǒng)的諧波問題早在20世紀20年代和30年代就引起了人們的注意。當(dāng)時在德國，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，從嚴格的意義來講，諧波是指電流中所含有的頻率為基波的整數(shù)倍的電量，一般是指對周期性的非正弦電量進行傅里葉級數(shù)分解，其余大于基波頻率的電流產(chǎn)生的電量。江蘇HPD99諧波保護器定做</p></p><br /><p>文章來源地址:
