并配以其它金屬氧化物,所以又稱為氧化鋅(Zno)避雷器。高壓避雷器是用來限制作用于線路絕緣和變電所絕緣上的大氣過電壓。避雷器的主要元件是火花間隙,它把工作導(dǎo)線和地隔開。幅值很高的進(jìn)行波使火花間隙動(dòng)作,從而把過電壓波截?cái)?。同時(shí)它還要熄滅隨著沖擊波擊穿而流過火花間隙的工頻續(xù)流電弧。YH10WZ-192-500,HY10WZ-192-500,YH5WZ-100/260,YH5WZ-102/266,YH5WZ-108/281,YH10WZ-100/260,YH10WZ-102/266,YH10WZ-108/281,HY5WZ-100/260,HY5WZ-102/266,HY5WZ-108/281,HY10WZ-100/260,HY10WZ-102/266,HY10WZ-108/281,HY10WZ-96/250,HY10WZ-90/235,HY5WZ-84/221,HY5WZ-90/235,HY5WZ-96/250,YH10WZ-96/250,YH10WZ-90/235,YH5WZ -84/221,YH5WZ -90/235,YH5WZ -96/250,HY10WZ-54/134,HY10WZ-51/134,YH10WZ-54/134,YH10WZ -51/134
