ARRESTER DISCONNECTOR ASSEMBLY MINIMIZING EXPLOSIVE SEPARATION

摘要

A disconnector assembly for an arrester includes a housing having first and second opposite ends. A cavity is disposed within the housing. A first electrical terminal is disposed at the first end of the housing, and a second electrical terminal is disposed at the second end of the housing. A cartridge with an explosive charge disposed in the cavity between the first and second electrical terminals. The cartridge has a powder load greater than 0 grams and not greater than approximately 0.15 grams. The powder load is sufficient to separate said second electrical terminal from said first electrical terminal upon cartridge detonation while minimizing the intensity of the explosive separation upon unintended cartridge detonation.
