Title:
SWITCHGEAR FOR ELECTRIC CURRENT WITH SEPARABLE ELECTRICAL CONTACT AND WITH AIR SWITCHING
Document Type and Number:
Japanese Patent JP2018137226
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a switchgear for an electric current with separable electrical contacts and with air switching.SOLUTION: A switchgear for an electric current includes: a switching assembly that can be switched between an open state and a closed state; a control mechanism including a trigger member (42) for triggering the switching of the switching assembly to the open state; and a housing (5) including lateral walls (51, 52). The lateral walls are elastically deformable when the pressure prevailing inside the housing (5) increases. One (52) of the lateral walls includes, on its inner face (521), a rigid protuberance (53), the deformation of the lateral wall causes a displacement of the protuberance, and the protuberance is arranged relative to the trigger member such that its displacement results in the displacement of the trigger member to its triggering position.SELECTED DRAWING: Figure 3
