FIELD: electricity.
SUBSTANCE: protection device comprises a spark gap (1, 1a) for protection against overvoltages, which comprises the first (4) and the second (5) connection terminals. At least one connection terminal (4, 5) is connected to an electric conducting connection current circuit (6), which is installed in a cardan manner. The cardan hinged joint (7, 7a) is retained with the second connection terminal (5) and comprises the first bracket (8) and the second bracket (9), entering each other. The first bracket (8) is connected to the second terminal (5). A device (11) is fixed to the second bracket (9) at the rigidly set angle for disconnection of the connection current circuit (6) in case of device failure.
EFFECT: reduced necessary structural space with elimination of external forces application to a device, which might cause mechanical damage.
