摘要： A surge arrester (1) comprising a stack of a plurality of cylindrical surge arrester elements (11) of a metal oxide varistor material, in which the arrester elements are arranged one after the other between two end electrodes (13) in the axial direction of the surge arrester and surrounded by a polymer insulator (12) making contact with the envelope surfaces of the surge arrester elements. Tension rods (14) are arranged in the polymer insulator in order to retain the surge arrester elements and the end electrodes. The polymer insulator is made of a polymer material which under normal operating conditions is resistant to deformation and is arranged with bulges (121) extending in the axial direction of the surge arrester along the length of the entire polymer insulator, the tension rods being arranged in these bulges. Voids (20) are arranged in the polymer insulator between the stack of surge arrester elements and the tension rods, these voids being preferably arranged close to the tension rods arranged in the bulges. The polymer insulator is arranged with notches (122) to enable it to burst in a controlled manner upon an elevated internal pressure. The notches are preferably arranged in the form of weakened points in the polymer insulator.

摘要： The invention relates to a surge arrester comprising a stack of arrester elements (1), for example of zinc oxide, arranged between two end electrodes (2) in an elongated insulating casing (3) of polymeric material, for example EPDM rubber. To mechanically reinforce the arrester, a tube (4) of fibre-reinforced plastic is arranged between the stack of arrester elements (1) and the polymer insulator (3). This tube (4) is manufactured by profile drawing, so-called pultrusion, whereby all reinforcement fibres extend in the axial direction of the tube. This gives the tube (4) a high tensile strength while at the same time the strength in the radial direction is relatively low. This is advantageous in the event of an arrester failure with an internal short circuit, since the tube will then easily crack up and provide a rapid pressure relief without any explosion hazard.
摘要翻译：本发明涉及一种电涌放电器，其包括布置在聚合材料的细长绝缘壳体（3）中的两个端电极（2）之间的例如氧化锌的避雷器元件（1），例如EPDM橡胶。为了机械加强避雷器，纤维增强塑料管（4）布置在避雷器元件（1）和聚合物绝缘体（3）之间。该管（4）通过型材拉拔制造，即所谓的拉挤成型，其中所有的增强纤维沿着管的轴向延伸。这使得管（4）具有高拉伸强度，同时径向强度相对较低。在内部短路的避雷器故障的情况下，这是有利的，因为管将容易地破裂并提供快速的压力释放而没有任何爆炸危险。
