style="text-indent:25px">熱敏電阻熱敏電阻可用作加熱元件外，同時(shí)還能起到“開(kāi)關(guān)”的作用，兼有敏感元件、加熱器和開(kāi)關(guān)三種功能，稱之為“熱敏開(kāi)關(guān)”．電流通過(guò)元件后引起溫度升高，即發(fā)熱體的溫度上升，當(dāng)超過(guò)居里點(diǎn)溫度后，電阻增加，從而限制電流增加，于是電流的下降增加元件溫度降低，電阻值的減小又使電路電流增加，元件溫度升高，周而復(fù)始，因此具有使溫度保持在特定范圍的功能，又起到開(kāi)關(guān)作用．利用這種阻溫特性做成加熱源，作為加熱元件應(yīng)用的有暖風(fēng)器、電烙鐵、烘衣柜、空調(diào)等，還可對(duì)電器起到過(guò)熱保護(hù)作用． NTC熱敏電阻器是一種負(fù)溫度系數(shù)熱敏電阻器，該產(chǎn)品的電阻值隨溫度升高而降低，根據(jù)其作用封裝成各種形狀以及具有不同的技術(shù)指標(biāo)。該產(chǎn)品主要用于溫度補(bǔ)償、溫度測(cè)量和在各類電源中吸收浪涌電流作為線路保護(hù)元件。同樣與壓敏電阻類似，熱敏電阻同樣在集團(tuán)電話交換機(jī)生產(chǎn)設(shè)計(jì)的時(shí)候已經(jīng)***采用。上述兩道防護(hù)措施防護(hù)普通的過(guò)流過(guò)壓保護(hù)已經(jīng)足夠了，但*靠它門來(lái)對(duì)付高達(dá)上萬(wàn)V的雷電時(shí)它們就力不從心了，瞬間會(huì)被擊穿、損壞。壓敏電阻和熱敏電阻共同的特點(diǎn)是：反映速度快能盡量避免高壓通過(guò)的瞬間損害設(shè)備，抗壓系數(shù)低，都是在低電壓的工作狀態(tài)。</p><div
