    Abstract: A preionizer for a surge voltage arrester, such as a lightening arrester, is formed by twisting the ends of a pair of wires, at least one of which is insulated except at its end, together so that the exposed ends of the wires form an ionizing gap that is essentially as long as the thickness of insulation between the two wires. After the ionizing gap is formed, an epoxy bead is used to encapsulate the twisted portion of the preionizer in order to maintain the desired gap spacing. The epoxy bead may also be utilized to position the ionizing gap adjacent a main gap or a trigger gap that is to have its sparkover level stabilized by the preionizing action of the twisted-wire preionizer of the invention.

    Abstract translation: 用于浪涌电压避雷器的前置离子灭活器,例如避雷器,通过扭转一对电线的端部而形成,其中至少一个电线在其端部绝缘在一起,使得电线的暴露端部形成离子化 间隙基本上与两条导线之间的绝缘厚度一样长。 在形成电离间隙之后,使用环氧树脂珠来封装预氧化剂的扭转部分,以便保持所需的间隙间隔。 环氧树脂珠也可用于将电离间隙邻近主间隙或触发间隙定位,以使其火花放电水平通过本发明的绞线去离子机的预除电作用而稳定。
