描述
DO470/A
供電系統(tǒng)的浪涌主要來自兩方面的原因:外部(雷電原因)和內(nèi)部(電氣設(shè)備啟停和故障等)。浪涌的特點往往是時間很短(雷電造成的過電壓往往在微秒級,電氣設(shè)備造成的過電壓往往在毫秒級),但是瞬時的電壓和電流極大,極有可能對用電設(shè)備和電纜造成危害,所以需要浪涌保護器對它們進行保護。
浪涌保護器,英文名SurgeProtectiveDevice,簡稱SPD,是一種為各種電子設(shè)備、儀器儀表、通訊線路提供安全防護的電子裝置,主要用于限制過電壓和泄放電涌電流。浪涌保護器一般是與被保護的設(shè)備并聯(lián),當產(chǎn)生過電壓時,可以起到分流和限壓的效果。防止過大的電流與電壓對設(shè)備產(chǎn)生損害。
浪涌保護器的核心元件是內(nèi)部的一個非線性元件。根據(jù)非線性元件的不同,浪涌保護器可以分為開關(guān)型(核心元件主要為放電間隙)和限壓型(核心元件主要為壓敏電阻)。
放電間隙和壓敏電阻的工作原理雖然有差異,但是基本的特性非常相似:在沒有過電壓時,他們的阻抗都非常高,一般是兆歐級,幾乎相當于斷路。當出現(xiàn)過電壓時,阻抗迅速下降到幾歐,浪涌電流就會通過浪涌保護器流入地,而不會進入設(shè)備,同時,由于浪涌保護器的這時的阻抗很小,它的兩遍電壓也比較小,同時因為他和被保護的設(shè)備并聯(lián),也就防止設(shè)備承受較大的浪涌電壓。這樣,就起到了泄流和限壓的效果。
