DISCHARGER FOR PROTECTION AGAINST OVERVOLTAGES WITH BODY AND AT LEAST ONE DISCHARGE ELEMENT Russian patent published in 2013 - IPC H01T1/14 

FIELD: electricity.

SUBSTANCE: invention relates to a discharger of protection against overvoltages with a body (10) and at least one discharge element, for instance, a varistor, and also a disconnecting accessory, serving to disconnect the discharge element or discharge elements from the grid. The disconnecting accessory includes a soldering area (14), which is a part of an electric path (A; B) of the connection within the discharger. Via the soldering area (14) a movable section of a conductor or a movable electroconductive link (3) is connected at one side with the discharge element, and at the other side - with the first electric outer lead of the discharger. The discharger also comprises a facility developing a pre-tensioning force, for instance, a spring (6; 11), besides, the appropriate vector of the force is directly or indirectly via a movable separating bracket (13) impacts the conductor area or the link (3) in direction of disconnection. On the way of movement of the conductor section or the link (3) there is a conducting element (4; 17), the first end of which with the actuated disconnecting accessory contacts with the section of the conductor or the link (3), besides, its second end is connected with the second external electric lead. The conducting element includes a switching device or its arranged in the form of a switching device.

EFFECT: higher reliability of conducting short-circuit current.
