Abstract:
A removable switching element for switching an electric current for an electrical switching device includes a housing; first and second fixed electrical conductors; a mobile electrical conductor that can be moved between a first position, in which the mobile electrical conductor electrically connects the first and second fixed electrical conductors; and a second position, in which the mobile electrical conductor is electrically isolated from the first and second fixed electrical conductors. The housing includes two windows passing therethrough, one being located facing an area of contact between the mobile conductor and the first fixed electrical conductor and the other being located facing an area of contact between the mobile conductor and the second fixed electrical conductor.
Abstract:
A removable electric current switching element includes first and second housing parts fitted to the other and that can be moved between an assembled configuration and a partially disassembled configuration. The first housing part includes side walls provided with through inspection windows, the second housing part includes insulating walls which each delimit a volume in the second housing part around a corresponding mobile conductor. The first and second housing parts are arranged relative to one another in such a way that, in the assembled configuration the insulating walls mask the inspection windows and that, in the intermediate configuration the insulating walls are away from the inspection windows to free access to the inspection windows.
Abstract:
An electrical switching device including an electric power switching module including a block of three input terminals and three output terminals, each input or output terminal being connected to a stationary contact of an electrical switch also including a mobile contact, configured to switch between an open position and a closed position, the mobile contact configured to be moved by an electromagnetic drive mechanism, and a control module, including at least one control input terminal and at least one control output terminal. The control module includes the electromagnetic drive mechanism configured to be supplied by the control terminals to control a position of one of the mobile contacts. A supervision module includes an auxiliary input contact terminal and two auxiliary output contact terminals, the auxiliary input contact terminal being shared by the two auxiliary output contact terminals, the power module being removable separately from the control and supervision modules.
Abstract:
A disconnecting electrical apparatus includes a disconnecting block, including elements for disconnecting an electric current each able to be actuated with a coupling member, to switch this disconnecting element to a blocking state or a state allowing the electric current to pass, an actuator block, provided with a controllable electromagnet suitable for generating an electromagnetic force, a mobile container provided with a magnetic plate, which displaces the coupling members, under the effect of the electromagnetic force, so as to switch the disconnecting elements. The apparatus also includes a connection interface inserted between the disconnecting block and the actuator block, the mobile container being housed inside the connection interface.
Abstract:
A module for the interconnection between an electrical circuit breaker and an electrical contactor includes a housing and multiple high-power electrical conductors that are housed inside the housing, each of the high-power electrical conductors being suitable for electrically connecting an electrical output of a circuit breaker to an electrical input of a contactor, in order to allow a supply electric current to flow from the circuit breaker to the contactor. The interconnection module additionally includes a device for measuring the current, which device is suitable for measuring the values of the current that flows through the high-power electrical conductors, and an electronic processing unit, which unit is equipped with an interface for connection to a data bus and which unit is programmed to transmit the values measured by the measurement device to the data bus.
Abstract:
An electromagnetic actuator, including: a ferromagnetic housing extending in a longitudinal direction with a height in a vertical direction perpendicular to the longitudinal direction; two coils arranged inside the housing, each including at least one winding around the longitudinal direction; a ferromagnetic member arranged between the coils; and a ferromagnetic plunger subjected to a magnetic field generated by the coils, the plunger movable in the longitudinal direction and to be immobilized in three different longitudinal positions depending on the field generated by the coils. The ferromagnetic member is rigidly connected to the housing and has, in the vertical direction, a size greater than one sixth of the height of the housing, and located at a distance smaller than one fourth of a gap in the longitudinal direction between the two coils, relative to a median plane perpendicular to the longitudinal direction and located at the midpoint between the two coils.
