電容器（英文：capacitor，用符號(hào)C表示）是將電能儲(chǔ)存在電場中的被動(dòng)電子元件，顧名思義它是一個(gè)裝載電荷的容器，在線性時(shí)不變系統(tǒng)中有：,模型如圖所示平行板電容器我們?cè)陔娐冯娐分型ǔＱ芯康氖瞧骷和i的關(guān)系，而電流的定義為：單位時(shí)間里通過導(dǎo)體任一橫截面的電荷量，即電流為電荷的變化率那么，從而得出電容的VCR（VoltageCurrentResistance）關(guān)系：但是在電路系統(tǒng)計(jì)算中，你愿意求解微積分方程嗎？因此電容和電感必須引入復(fù)域，才能讓問題得到有效解決。當(dāng)然時(shí)域研究也是有用處的，以后在測量篇會(huì)講解。這里采用倒敘的方法，先提前說下電容的阻抗為，w和C大家都知道是角頻率和容值，那復(fù)數(shù)j是什么，怎么來的呢？還記得我在電阻篇說過電容是一個(gè)跟電阻差了90度并且隨著頻率變化的器件。這里的隨頻率變換體現(xiàn)在w上，那么90度體現(xiàn)在哪里呢，想一想應(yīng)該就是這個(gè)j了，因?yàn)閣和C都是實(shí)數(shù)不會(huì)出現(xiàn)角度變換，那么這個(gè)j就對(duì)應(yīng)了90度。再看下這個(gè)公式怎么解釋我們平時(shí)知道的電容特性，我們知道電容通高頻，阻低頻，就是隨著頻率增高阻抗越小，剛好跟公式w和C在分母上對(duì)應(yīng)，隨著頻率增加，電容的阻抗降低。在上面的電容阻抗公式中，我們知道了復(fù)數(shù)j對(duì)應(yīng)的是角度（900）。</p><p> 濾波功能利用的是電容的阻抗隨頻率變化的特性（前面說過電容是一個(gè)跟電阻差了90度并且隨著頻率變化的器件），再利用電阻篇講的分壓原理，就可以構(gòu)成簡單的無源RC濾波器了。濾波指的是濾出不需要頻率的波形,濾波器的類型有低通、高通、帶通、帶阻。舉個(gè)例子：設(shè)計(jì)一個(gè)頻率為1Kz的一階低無源低通RC濾波器。先確定濾波器的形狀和電容的大小，然后再求出電阻的值。首先電容不可能是串聯(lián)在電路中，如果串聯(lián)在電路中那么直流沒法通過，那么就不是低通濾波器了。因此確定了如圖所示的分壓模式。電容的選取，有很多講究。需要要根據(jù)輸入輸出阻抗，濾波器要求的精度，頻率大小，現(xiàn)有電容器種類等選擇。這里先選擇一個(gè)100nF的電容，因?yàn)楦呔鹊碾娙萑葜刀疾淮螅⑶?Kz頻率下100nF電容的阻抗約等于，電阻在1K-10K之間是工程師常用的，因?yàn)樽柚翟谶@個(gè)范圍電阻的功耗不大，并且熱噪聲也相對(duì)較?。娮柙酱鬅嵩肼曉酱螅?。因此先確定電容為100nF。那么可能有人會(huì)問，為什么不先確定電阻，再選電容呢？這就要考慮實(shí)際情況了，因?yàn)殡娮璧姆N類比電容多很多，選取相對(duì)容易，因此這里要先定電容，再根據(jù)電容的阻抗選取電阻。接下來讓我們分壓公式。耦合電容器質(zhì)量哪家好，歡迎來電咨詢，無錫市錫容電力電器有限公司。</p><div

電力系統(tǒng)中，電力電容器是必不可少的，起著非常重要的作用。近些年來，由于我國電力系統(tǒng)的迅猛發(fā)展，大量的電力電容器設(shè)備在電力系統(tǒng)中使用，而并聯(lián)電容器作為現(xiàn)今優(yōu)先采用的無功功率補(bǔ)償裝置，對(duì)供電企業(yè)的作用顯得十分明顯。由于電力電容器需要頻繁的投切，外界環(huán)境因素的變化等會(huì)對(duì)電容器本身的影響較大，尤其是在環(huán)境溫度超出電容器正常運(yùn)行所允許的溫度之后，容易導(dǎo)致絕緣介質(zhì)發(fā)生變化，損壞電容器。作者介紹了幾種常見的耐高溫電力電容器，分析了溫度對(duì)電力電容器安全運(yùn)行的影響，并針對(duì)高溫對(duì)電容器的影響，提出了處理措施。1幾種常見的耐高溫電力電容器芐基甲苯浸漬聚丙烯薄膜電容器隨著電力電容器技術(shù)的發(fā)展,聚丙烯薄膜介質(zhì)浸漬芐基甲苯的介質(zhì)結(jié)構(gòu)被用在高壓并聯(lián)電容器、串聯(lián)電容器等設(shè)計(jì)中。芐基甲苯浸漬聚丙烯薄膜電容器具有對(duì)介質(zhì)損耗小、溫升低、比特性好等優(yōu)點(diǎn)，一般其運(yùn)行的溫度不會(huì)超過65℃。芐基甲苯浸漬聚丙烯薄膜電容器具有良好的性能，與其使用的電力電容器浸漬劑有著密切的關(guān)系。芐基甲苯浸漬聚丙烯薄膜電容器使用的電力電容器浸漬劑具有絕緣強(qiáng)度高、電氣物理特性良好、性能穩(wěn)定、介質(zhì)損耗小、耐高溫等特點(diǎn)，是目前市場上性能好的電力電容器浸漬劑之一。杭州電容器質(zhì)量哪家好，歡迎來電咨詢，無錫市錫容電力電器有限公司。鹽城濾波電容器定做</p><p
