摘要： A device for protecting an electrical system against surge voltages, comprising one or more protection components (10), means (20) for disconnecting the protection component (10) and means (30) for visually indicating the state of said component (10), operationally connected to the disconnection means (20) and comprising at least one control part (40) and at least one means (50) for indicating the state of the protection component (10), combined with said control part (40), characterised in that the relative arrangement of said control part (40) and said disconnection means (20) is such that, when the latter are opened (20), they release the control part (40), thereby allowing it to move. Electrical surge voltage protection devices are also described.

摘要： The invention relates to an overvoltage protection device (1) embodied to provide protection in common or differential modes and comprising at least one electrically-insulated housing (2), specifically embodied to house at least one electrical binomial, formed by a so-called ground-phase varistor (PT), with a phase connector (p) and a ground connector (t), arranged between a first phase (L1) for protection and ground (T) and a so-called neutral-phase varistor (PN), with a phase connector (p) and a neutral connector (n), arranged between said first phase (L1) for protection and neutral (N), said phase-ground (PT) and phase-neutral (PN) varistors being mounted next to each other within said housing (2) such as to form an assembly binomial (3), characterised in that the protection device (1) comprises electrical insulation means (20), embodied for the electrical insulation of the ground connection (t) from the phase-ground varistor (PT) and the neutral connection (n) from the phase-neutral varistor (PN). The invention relates to devices for protection against overvoltages.

摘要： The invention relates to a device which is used to protect an electrical installation against overvoltages. The inventive device consists of: a protection component (10); means (20) for disconnecting the protection component (10); and means (30) for displaying the state of the protection component (10), comprising a control part (40) which can move and a display member (50) which indicates if the protection component (10) is in service or disconnected according to the position of the control part (40). The invention is characterised in that the control part (40) and the disconnection means (20) are disposed such that, when opening, the disconnection means (20) move away sufficiently from the control part (40) in order to release and, in this way, authorise the free movement of the control part (40). The invention also relates to electrical overvoltage protection devices.

摘要： A device for protecting an electrical system against surge voltages, comprising one or more protection components (10) provided with means (20) for connecting same with said system and means (30) for disconnecting said component (10) from said system, characterised in that it comprises arc-breaking means (40) for preventing the generation of electric arcs between the disconnection means (30) and the connection means (20) when the disconnection means (30) is in an open state, wherein said arc-breaking means (40) consist of an insulating flap (41) capable of moving within the gap (11) and comprising a central portion (42) to be positioned between the disconnection (30) and connection (20) means, and side portions (43) shaped in such a way as to prevent the electric arc from bypassing the arc-breaking means (40). Electrical surge voltage protection devices are also described.
