    摘 要:自恢復(fù)式過欠壓保護(hù)器(OUPA)是近來電器保護(hù)器新增類別。介紹了OUPA的分類,并從OUPA的工作原理框圖、過欠壓值的設(shè)定、動(dòng)作特性試驗(yàn)電路以及使用注意事項(xiàng)等方面進(jìn)行了詳細(xì)的闡述,指出從市場(chǎng)需求看,不僅有過欠壓保護(hù)且還具有過流保護(hù)的OUPA,在用電保護(hù)方面的應(yīng)用前景將愈發(fā)廣泛。
    關(guān)鍵詞:自恢復(fù)式過欠壓保護(hù)器;動(dòng)作特性;特性試驗(yàn)

    Abstract: The overvoltage/undervoltage protective device with auto-reclosing function (OUPA) is a new type of electrical protector recently. This article introduces the classification of protectors OUPA, and elaborates in detail from the working principle block diagram of OUPA, the setting of overvoltage and undervoltage values, the operating characteristic test circuit, and precautions for use. The article points out that from the perspective of market demand, OUPA not only has over- and under-voltage protection, but also has over-current protection, and its application prospects in power protection will become more extensive.
    Key words: overvoltage/undervoltage protective device with auto-reclosing function; action characteristic; characteristics test
