The present invention employs a separate rotation-adjusting member, which allows a position of a circuit breaker or a transformer to be recognized from outside without an error.

A secondary disconnect assembly is for an electrical switching apparatus. The secondary disconnect assembly includes a mounting member and a cradle assembly coupled to the mounting member and being movable among a plurality of positions with respect to the mounting member. The cradle assembly includes an inner cradle. When the inner cradle is disposed in a first predetermined one of the positions, movement of the inner cradle is restricted with respect to the mounting member. When the inner cradle is moved toward a second predetermined one of the positions, the inner cradle moves independently with respect to the mounting member.

A secondary disconnect assembly for a switching device includes a first mounting bracket configured to support a secondary connector of a switching device system, a telescopic arrangement connected to the first mounting bracket, a slider connected to the telescopic arrangement, and a second mounting bracket including a projection. The second mounting bracket is operable to move with the switching device. The slider is engageable with the projection and movable with the second mounting bracket in an automatic operation of the secondary disconnect assembly. The slider is disengageable from the projection and movable with respect to the second mounting bracket in a manual operation of the secondary disconnect assembly.

An automatic autonomous redundant switch configured for providing energy from either a first power source or a second power source to a load is provided. The automatic switch includes a first automatic transfer switch (ATS) and a second ATS. The automatic switch further includes an interconnecting bus configured to connect the first ATS and the second ATS, and at least one controller configured to control the operation of the first ATS and the second ATS. Still further, the first ATS and the second ATS each include a respective transfer-switch mechanism, a respective bus attachment configured to connect to the interconnecting bus, and a respective motorized rack-out mechanism having a powered actuator.

A switching apparatus for electric power distribution grids including: a withdrawable first switching unit having one or more first electric poles; a withdrawable second switching unit having one or more second electric poles and electrically connected ins series with said first switching unit; and a controller implementing control strategies directed to increase the safety of the withdrawal manoeuvres of said first and second switching units.

A device for monitoring vacuum quality of a vacuum circuit breaker, the device including at least one rigid assembly including a first stationary conductive surface that is separated by an insulating layer from a second stationary conductive surface that is grounded. The assembly forms a first capacitor having a fixed value, the first stationary conductive surface being arranged opposite an electrically active portion of the vacuum circuit breaker to form, together with the portion, a second capacitor, and an electronic circuit for measuring a variation in voltage of the first capacitor that is representative of a change in state of the vacuum of the circuit breaker.

A substation for medium or high voltage includes: switchgear or controlgear with unmanned operation and maintenance; an inner room in which the switchgear or controlgear is located, the inner room being hermetically enclosed by an outer housing, the inner room being locked against the outer housing by an inner, automatically operated door; and a robot system, the robot system being implemented such that an acting area of the robot system is extended from the inner room, partly in an area outside the inner room, but within the substation internal space, where spare parts are stored in a spare parts hand over area, for maintenance.

A circuit breaker racking system includes an electrical drive operatively connected to a mechanical racking mechanism that carries the circuit breaker and moves the circuit breaker between a connect position and a disconnect position within a cubicle, and a circuit breaker trip unit that receives remote commands and controls the electrical drive based on the remote commands. A switchgear system including at least one circuit breaker with an integrated auto-racking system is also provided.
