    • To ensure a surface pressure on the interface between the insertion hole in a bushing and a rubber mold body to prevent a void from occurring. The inventive bushing (2) is provided with an insertion hole (3a) for housing an arrester mold body (6), and a tapered insertion hole (53a) spreading in a conical shape from the high pressure side of the bushing (2) to the low pressure side is provided in a region where electric field of the insertion hole (3a) concentrates. The arrester mold body (6) is provided with a rubber mold body (67) consisting of silicone rubber or the like integrally molded around the outer periphery of an arrester element laminate (61), and the rubber mold body (67) is provided with a conical portion (67b) to be able to be fitted to the tapered inner surface of the tapered insertion hole (53a). ® KIPO & WIPO 2009
    • 确保衬套上的插入孔和橡胶模具体之间的界面上的表面压力,以防止发生空隙。 本发明的衬套(2)设置有用于容纳避雷器模具本体(6)的插入孔(3a)和从衬套(2)的高压侧向锥形扩展的锥形插入孔(53a), 低压侧设置在插入孔(3a)的电场集中的区域。 避雷器模具本体(6)设置有由围绕避雷器元件叠层体(61)的外周整体成形的硅橡胶等构成的橡胶模体(67),橡胶模体(67) 锥形部分(67b)能够装配到锥形插入孔(53a)的锥形内表面。 ®KIPO&WIPO 2009
