Abstract: A pole actuation booster mechanism for a four-poles low voltage circuit breaker, which includes: a first operating member adapted to be operatively connected to the operating shaft of the circuit breaker and moving together with said shaft during its rotation from an open position to a closed position, and vice-versa, of said circuit breaker over a range of movement having a first, a second and a third portion of movement, the first operating member having a first operating end; an operating assembly including at least an elastic element operatively connected to a lever, the first operating member being disengaged from said operating assembly during the first portion of its movement and engaged with the lever during the second and third portions of its movement. During a closing operation of the circuit breaker the first operating member moves first along the first portion of movement driven by the operating shaft and disengaged from the operating assembly, then moves along the second portion of movement driven by the operating shaft and engaged with the lever and transmitting energy to the operating assembly; and finally moves along the third portion of movement driven by the lever and transmitting energy to the operating shaft.

Abstract: The present application provides a residual-current protection device and a tripper. The residual-current protection device comprises: a flux transformer receiving a residual-current signal; a tripping output element outputting ON/OFF signals; an energy storage mechanism adapted to switch between an energy storage state and an energy release state, the energy storage mechanism having a locking unit that locks the energy storage mechanism in the energy storage state; and a transmission mechanism braked by the flux transformer, which drives the tripping output element to move and drives state of the energy storage mechanism to switch; the transmission mechanism comprising: a first rack cooperating with the locking unit, a second rack driving the tripping output element, and a reduction gear with a big gear engaged with the first rack and a small gear engaged with the second rack. By means of the gear rack transmission mechanism of the residual-current protection device, reduction transmission can be effected, driving force needed by energy storage may be reduced, and thus design requirements as high transmission efficiency, easy processing and assembly as well as low costs can be satisfied.

Abstract: Systems, methods, techniques and apparatuses for configuring load shed controllers are disclosed. One exemplary embodiment is a method comprising providing a graphic user interface on a computer display; providing first, second, third, and fourth graphic resources on said graphic user interface; checking whether said load shedding controller meets minimum operating requirements to operate; if said load shedding controller meets said minimum operating requirements, transmitting configuration information including at least first and second configuration values to said load shedding controller; and controlling, with the load shedding controller, the one or more of the electric loads based on the first and second configuration values. The third graphic resources assist a user in providing first configuration values to configure grid operating parameters. The fourth graphic resources assist a user in providing second configuration values to configure load operating parameters.

Abstract: A device for monitoring a current in a primary conductor with respect to a predetermined current threshold, comprising: a magnetic circuit associable to the primary conductor and comprising a fixed part and an element which can rotate about a rotation axis; at least one spring operatively connected to the rotating element for keeping it in a first position, the spring being elastically deformable along a linear axis; and sensing means operatively associated to the magnetic circuit. The magnetic circuit is configured in such a way that the rotating element rotates from the first position to a second position when the current in the primary conductor exceeds the predetermined current threshold, so as to at least reduce one or more air gaps between the rotating element and the fixed part and to elongate the spring from a first length to a second length. The sensing means are configured for generating an output electrical signal caused by the rotation of the rotating element from the first position to the second position.The at least one spring is operatively connected to the rotating element in such a way to tilt towards the rotation axis moving above a surface of the rotating element which is transversal to the rotation axis, during the rotation of the rotating element from the first position to the second position.
