Embodiment Construction

[0035] The device according to the invention for providing protection against voltage surges is designed to be connected in parallel with the electrical installation or device to be protected. The term "electrical installation" refers to any type of electrical network or equipment that may be subject to voltage disturbances, especially transient surges due to lightning.

[0036] The device according to the invention for providing protection against surges is advantageously designed to be placed between a phase of the installation to be protected and the earth. Without going beyond the scope of the invention, it is also conceivable to connect the protective device not in parallel between a phase and earth, but between neutral and earth, between phase and neutral, or actually Connected between two phases (for differential protection).

[0037] The protective device 1 according to the invention comprises at least one protective component 10 for protecting an electrical installat...

Abstract

The invention relates to a device (1) for protecting an electric installation against overvoltage comprising at least one protection component (10) provided with means for connecting to said electric installation, means for disconnecting the protection component (10) therefrom which are movable from a closed position to an open position, thereby forming an interstitial space (11) between the disconnecting and connecting means in such a way that an electric arc is formed therein. The inventive device is characterised in that it is provided with means (50) which approaches said electric arc from at least two different directions in order to reduce the cross-section thereof. Said invention is used for protecting against overvoltage.

Description

technical field [0001] The present invention relates to the general technical field of devices for protecting electrical equipment and installations against transient voltage surges, notably due to lightning. [0002] The invention more particularly relates to a device for protecting electrical installations against voltage surges, the device comprising: [0003] at least one protective component, equipped with connecting means for connecting to the electrical installation; and disconnecting means, for disconnecting the protective component from the electrical installation, and adapted to disconnect the protective component through the connecting means, the disconnecting means being suitable for Moving from the closed position to the open position, a gap is thereby created between the disconnecting device and the connecting device, so that arcs may form in this gap between the disconnecting device and the connecting device. [0004] The invention also relates to a method of i...
