Abstract:
The invention relates to a voltage limiting device which has an electromagnetically operable switching device for producing an electrical connection between a first cable terminal and a second cable terminal wherein a first electrical conductor connects the first cable terminal to the one terminal of the switching device and a second electrical conductor electrically connects the second cable terminal to the other terminal of the switching device. The voltage limiting device is characterized in that one of the two electrical conductors comprises an electrically conductive support plate. The expansion of the support plate in the width direction allows, in contrast to an electrical conductor which is characterized by a small width in relation to the length, a current displacement in the width direction. As a result, the forces acting on the conductive parts of the switching device are reduced and the switching contacts are relieved, as a result of which the electrical properties of the voltage limiting device are improved. As an electrical conductor, the support plate improves not only the electrical properties of the voltage limiting device, but as a mounting plate also simplifies the assembly and mounting of the individual components of the voltage limiting device.
