YH1.5W-0.28/1.3避雷器用于保護(hù)系統(tǒng)額定電壓10KV的電力變壓器、開關(guān)柜、箱式變電站、電力電纜出線頭、柱上油開關(guān)等配電設(shè)備免受大氣和操作過電壓的損壞。
氧化鋅避雷器除具備金屬氧化物避雷器的過電壓保護(hù)功能外,又可在發(fā)生異常故障時(shí),工頻短路電流使脫離器動(dòng)作,其接地端自動(dòng)脫開,氧化鋅避雷器退出電網(wǎng)運(yùn)行,檢修維護(hù)方便,易于發(fā)現(xiàn)故障點(diǎn)。 帶脫離器避雷器工作原理簡(jiǎn)介: 當(dāng)氧化鋅避雷器出現(xiàn)故障時(shí), 主要表現(xiàn)為流經(jīng)閥片的電流增大,使閥片組呈發(fā)熱狀態(tài), 由于閥片組為負(fù)溫度系數(shù),發(fā)熱引起等效電阻下降,又促使發(fā)熱加劇,形成性循環(huán)。
