摘要： The invention relates to a surge arrester (1) for use in the power supply of low-voltage networks, in particular for use between a neutral conductor N and a potential equalization means PE, comprising a cylindrical housing (2), two electrodes (3, 4) arranged axially opposite each other, and an arc chamber (5) formed inside the housing (2), wherein the arc chamber (5) is axially bounded by the two electrodes (3, 4) and a spark gap is formed between the two electrodes (3, 4) such that an arc is produced when the spark gap between the two electrodes (3, 4) is ignited. In the case of the surge arrester according to the invention, the blowing out of ionized gases can be dispensed, because two chambers (6, 7) are formed within the housing (2), each of which two chambers is connected to the arc chamber (5) by means of two channels (8, 9) such that hot ionized gas can flow from the arc chamber (5) into the chambers (6, 7) after the ignition of the spark gap, wherein the volume of the two chambers (6, 7) together is greater than the volume of the arc chamber (5) and wherein the two chambers (6, 7) are arranged on opposite sides of the arc chamber (5) in a longitudinal direction of the housing (2) and each have an axial and a radial distance from the arc chamber (5).
摘要翻译： 本发明涉及一种用于低压电网电源的电涌放电器（1），特别是用于中性导体N和电位均衡装置PE之间，包括一个圆柱形外壳（2），两个电极（3） ，所述电弧室（5）在轴向上彼此相对布置，并且在所述壳体（2）内部形成电弧室（5），其中所述电弧室（5）在轴向上由所述两个电极（3,4）限制，并且在 两个电极（3,4）使得当两个电极（3,4）之间的火花隙被点燃时产生电弧。 在根据本发明的电涌放电器的情况下，可以分配电离气体的吹出，因为两个室（6,7）形成在壳体（2）内，其中两个室中的每一个连接到电弧室 （5）通过两个通道（8,9）连接，使得热电离气体在点火火花间隙之后能够从电弧室（5）流入室（6,7），其中两个室 （6,7）一起大于电弧室（5）的体积，并且其中两个室（6,7）在壳体（2）的纵向方向上布置在电弧室（5）的相对侧上， 并且各自具有离电弧室（5）的轴向和径向距离。
