SURGE ARRESTOR COMPRISING AT LEAST ONE ARRESTOR ELEMENT

摘要

A surge arrestor includes at least one arrestor element, and a disconnecting device for disconnecting the arrestor element from the grid. The disconnecting device includes a thermal disconnect point that is incorporated into the electrical connection path within the arrestor. A moving conductor section or a moving conductive bridge is connected to the arrestor element by way of the disconnect point. A conducting element is disposed in or at the end of the path of motion of the conductor section or of the bridge, the conducting element coming into contact with the conductor section or the bridge when the disconnecting device is triggered. A moving insulation part penetrates into the path of motion of the conductor section or of the bridge directly prior to or upon reaching a short circuit state.
