Method and apparatus for manufacturing a surge arrester |
摘要 |
A distribution class surge arrester comprises a core formed of distributed zinc oxide varistor blocks, aluminum blocks acting as heat sinks and as spacers providing voltage grading and required arcing distances, and terminal blocks held in face-to-face contact by means of a glass reinforced epoxy shell which is formed by winding a pre-preg onto the assembled blocks and thermally curing under mold pressure within an evacuated mold. The core is housed within a polymeric shedded housing which is formed by shrinking a heat-shrink shedded sleeve onto the core with a sealant provided in the interface of the core and the sleeve, and end caps are sealed to the ends of the structure thus formed. The all solid-state arrester thus formed has performance and cost advantages over conventional porcelain housed arresters and furthermore has very considerable physical strength enabling it to serve additionally as a stand-off support insulator in situations where conventionally separate arrester and support insulators were required.
