瓷外套金屬氧化物避雷器及主要技術參數(shù)

1、瓷外套金屬氧化物避雷器及主要技術參數(shù)瓷外套式金屬氧化物避雷器可用于限制變壓器、電容器、真空開關、變壓器中性點等的過電壓。該產(chǎn)品內部采用了優(yōu)質半導體材料，高強度棒以及金屬壓板把電阻片固定在同心圓內，使避雷器整體結構更加牢固，保證了在安裝和運輸過程中產(chǎn)品內部原件仍然保持良好的接觸，減少局部放電量，并且半導體材料形成的保護層使得電阻片避免吸潮，延長了其側面的有效爬距，從而提高了產(chǎn)品的可靠性，延長了使用壽命。避雷器主要技術參數(shù)列表如下： 表一 配電型Y5W 、 Y5WS系列產(chǎn) 品型 號避雷器額定電壓系統(tǒng)額定電壓持續(xù)運行電壓直流參考電壓U1mA不小于8/20us標稱電流下殘壓方波通流容量2ms 18次4
