Abstract:
A linear actuator assembly (200,200',200'') is for an electrical switching apparatus (100,100',100''), such as a multi-pole circuit breaker. The circuit breaker includes a plurality of pole units (102,104,106;102',104',106',102'',104'',106'') each having separable contacts (110). The linear actuator assembly (200,200',200'') includes a base unit (202,202',202'') comprising a housing (204,204',204''), and a plurality of linear actuators (302,304,306;302',304',306';302'',304'',306''). Each linear actuator (302,304,306;302',304',306';302'',304'',306'') is mounted within the housing (204,204',204'') in alignment with a corresponding one of the pole units (102,104,106;102',104',106';102'',104'',106''). Each linear actuator (302,304,306;302',304',306';302'',304'',306'') actuates the separable contacts (110) of the corresponding one of the pole units (102,104,106;102',104',106';102'',104'',106''). A controller (402) is adapted to control actuation of the linear actuators (302,304,306;302',304',306';302'',304'',306'').
Abstract:
An insulated switchgear module is disclosed. In one example, the module comprises a vacuum interrupter, current exchange assembly, and end conductors disposed within an insulated housing. The insulated housing further comprises a tank containing an actuator mechanism for actuating the current exchange assembly. An insulating tray within the housing separates the vacuum interrupter from the components in the tank. The insulated tray has a shape that corresponds with the shape of the vacuum interrupter and the shape of tire housing.

Abstract:
An interrupter system for a switchgear. The interrupter system includes a source-side conductor, a load side conductor, and an interrupter. A source-side voltage detector is positioned proximate to the source-side conductor and a load-side voltage detector is positioned proximate to the load- side conductor. An insulating overmold encases both conductors, both voltage detectors, and the interrupter. A controller is coupled to both of the detectors and is configured to detect a source- side voltage and a load-side voltage.
Abstract:
The current in a generator circuit breaker (3) is measured by means of the Faraday effect of an optical sensing fiber (7) looped around the breaker's conductor (4). The sensing fiber (7) is arranged in a sensing strip (29), which can be mounted to the enclosure (20) of the generator circuit breaker or to the conductor (4). The design has a wide measuring range and can easily be fitted to new or existing generator circuit breakers.

The invention relates to a leadthrough arrangement (1) comprising a separating switch component which is connected to an electrically insulating cover (10) in the manner of an open-air leadthrough. A tubular shaped electrode (9) is arranged in the flange area of the electrically insulating cover (10) and the separating switch component, said electrode projecting over the flange (4). A common gas chamber is formed by the electrically insulating cover (10) and the housing (2) of the separating switch component.
Abstract:
Apparatus (10) for interrupting the flow of current in a power distribution system is disclosed for use with an enclosure containing insulating fluid. The apparatus (10) includes a housing (20) formed from insulating material and having a mounting flange (28) formed along the exterior of the housing (20). The flange (28) is located so that the housing extends away from the mounting side and the upper side of the flange. An electrical current interrupter (16), having electrical input and output ends (16a, 16b), is positioned in the housing (20) so that a portion lies within the portion of the housing extending away from the flange mounting side. An actuator (12) is mechanically connected to the interrupter (16) to provide the mechanical actuation required to interrupt the current flow between the input and output ends of the interrupter. When the flange (28) is attached to the enclosure, the portion of the housing (20) extending away from the flange mounting side extends into the fluid within the enclosure.
