SURGE DIVERTER COMPRISING A HOUSING AND AT LEAST ONE DIVERTING ELEMENT, ESPECIALLY A VARISTOR

摘要

The invention relates to a surge diverter comprising a housing, at least one diverting element, especially a varistor, and a device for disconnecting the diverting element/s from the mains. The disconnecting device encompasses an isolating point, particularly a soldered joint, which is integrated into the electrical connection path within the diverter. Via the soldered joint, a movable conductor section or a movable conducting bridge is connected to the diverting element, and the conductor section or the bridge is connected to a first external electrical connection of the diverter. The disconnecting device also encompasses a means generating a biasing force, e.g. a spring, the force vector of which acts on the conductor section or the bridge in the disconnecting direction. According to the invention, a commutation branch is provided in parallel to the disconnecting device. Said commutation branch is permanently electrically connected in parallel once a defined voltage has been reached over the disconnecting device or in accordance with a predefined disconnecting distance of the disconnecting device.
