style="text-indent:25px">近年，隨著知識(shí)經(jīng)濟(jì)與信息時(shí)代的到來，電子計(jì)算機(jī)、精密醫(yī)療儀器、微處理器以及其它數(shù)字化電子設(shè)備應(yīng)用日益普遍；電子計(jì)算機(jī)、微處理器以及其他電子儀器設(shè)備普遍存在對(duì)供電電源的諧波質(zhì)量要求很高的特點(diǎn)，由于高次諧波的存在，使得這些高靈敏的電子系統(tǒng)中運(yùn)行時(shí)，經(jīng)常出現(xiàn)程序運(yùn)行錯(cuò)誤、數(shù)據(jù)錯(cuò)誤、時(shí)間錯(cuò)誤、死機(jī)、無故重新啟動(dòng)甚至造成用電設(shè)備長(zhǎng)久性損壞，給人們的工作和日常生活造成了巨大損失。一般設(shè)備在“瞬變”發(fā)生頻次20萬次／小時(shí)狀態(tài)下工作，電子設(shè)備壽命會(huì)縮短40%，電機(jī)設(shè)備壽命會(huì)縮短30%，照明設(shè)備壽命會(huì)縮短35%~45%據(jù)統(tǒng)計(jì)，電子設(shè)備的故障有75%是由于瞬變和浪涌造成的?；旧厦慨?dāng)一個(gè)電感性負(fù)荷被切斷時(shí)，就會(huì)有比正常電壓的峰值高很多倍的用戶側(cè)高次諧波產(chǎn)生。諧波保護(hù)器的操縱非?？旖莺?jiǎn)單。</p><div

style="text-indent:25px">電力系統(tǒng)中，諧波保護(hù)指什么？我國(guó)電力系統(tǒng)的頻率為50Hz,，即每秒50周。由于電機(jī)制造、變壓器鐵芯等多種因素，系統(tǒng)內(nèi)會(huì)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(gè)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(dá)的部分。從嚴(yán)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(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。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(shí)“諧波”這個(gè)詞的的意義已經(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”等等說法。工廠諧波保護(hù)器裝置價(jià)格</p></p><br
