The invention relates to a voltage limiting device having a switching device (5) with a movable switching contact (16) which can be moved between a closed position and an open position, an electrical conductor (10) electrically connecting a first cable connection (11) to the switching device and an electrical conductor (12) electrically connecting a second cable connection (13) to the switching device. The voltage limiting device according to the invention is characterized by a special arrangement and design of the conductor parts of one of the two electrical conductors (10, 12). The conductor portions (10B, 12B) of the electrical conductors (10, 12) are arranged or designed in such a way that the conductor portions together with the movable switching contacts (16) of the switching device (5) form a conductor arrangement through which current flows in opposite directions during operation of the switching device. Thus, an electrodynamic force acts on the movable conductor and the fixed conductor, the direction of the electrodynamic force being such that the conductors repel each other. Therefore, the switch contact tends to be closed. The voltage limiting device can switch higher loads without reinforcing conductive components or taking other technical measures.

    本发明涉及一种电压限制设备,该电压限制设备具有开关装置(5),该开关装置具有可在闭合位置和断开位置之间移动的可动开关触点(16),其中,电导体(10)将第一缆线连接端(11)与开关装置电连接,电导体(12)将第二缆线连接端(13)与开关装置电连接。根据本发明的电压限制设备的特征在于两个电导体(10、12)之一的导体部分的特别排列和设计。电导体(10、12)的导体部分(10B、12B)被布置或设计为使得该导体部分与开关装置(5)的可动开关触点(16)一起形成在开关装置运行期间流过相反方向电流的导体排列。因此,电动力作用在可动导体和固定导体上,所述电动力的方向为使得导体相互排斥。因此,开关触点趋于闭合。该电压限制设备可以切换更高的负载,而无需加固导电部件或采取其他技术措施。
