3，低維護成本正常情況下，防雷設(shè)備是不需要維護，即使發(fā)生了每一次的損耗，如：被擊傳等現(xiàn)象，*需要更換該線路的**元件。每一次損耗都是對設(shè)備保護價值的體現(xiàn)。幾百元至幾千元的防雷設(shè)備投資對數(shù)千元甚至數(shù)萬的設(shè)備來講，完全是有價值的。</p><p

輕微損壞或完全防護。各級放護元件根據(jù)其特性、標準值會有一個極限值當(dāng)遭遇強電超出其可耐受范圍時就會出現(xiàn)“魚死網(wǎng)破”的局面…..防護元件在消耗一部分能量之后會被擊傳！損壞、甚至炸裂…這種現(xiàn)象會導(dǎo)致防護元件無法重復(fù)使用必須更換，但相對于減輕對設(shè)備價值角度來講這點損失是完全有必要的。所以即使有相關(guān)的防護措施的用戶應(yīng)當(dāng)在雷雨過后或每年雷雨季節(jié)到來之前檢查是否完好。泉州電話交換機系統(tǒng)報價</p><p
