A switchgear or control gear includes: a first compartment; at least one removable module; a plurality of main switchgear or control gear components; and a plurality of auxiliary switchgear or control gear components. The plurality of main switchgear or control gear components are sub-divided into a first group of components that have a lifetime greater than a threshold level and a second group of components that have a lifetime less than or equal to the threshold level. The plurality of auxiliary switchgear or control gear components are sub-divided into a first group of components that have a lifetime greater than the threshold level and a second group of components that have a lifetime less than or equal to the threshold level.

Switchgear

A switchgear or control gear includes: at least one first compartment; a second compartment; a plurality of main switchgear or control gear components, the plurality of main switchgear or control gear components including a main busbar system, a three position linear or rotational movement disconnector, a circuit breaker, and a cable connection; and a plurality of auxiliary switchgear or control gear components, the plurality of auxiliary switchgear or control gear components including a disconnector drive and a circuit breaker drive. The plurality of main switchgear or control gear components are housed in the at least one first compartment. The plurality of auxiliary switchgear or control components are housed in the second compartment. The circuit breaker and three position or rotational movement disconnector are mounted vertically in the at least one first compartment.

Three phase switchgear or control gear

A switchgear or control gear includes at least one first compartment; a plurality of removable modules; a plurality of main switchgear or control gear components; and a plurality of auxiliary switchgear or control gear components. The plurality of main switchgear or control gear components includes at least one main busbar system, at least one three position linear or rotational movement disconnector, at least one circuit breaker, and at least one cable connection. The plurality of auxiliary switchgear or control gear components includes at least one disconnector drive and at least one circuit breaker drive. The plurality of removable modules are configured to be mounted horizontally within the at least one first compartment at a plurality of horizontal locations. Movement of a removable module from its horizontal location, the movement including a vertical movement, is configured to move the one or more auxiliary components housed in or associated with that module.

Switchgear or control gear

A three phase switchgear or control gear includes: at least one compartment; a plurality of components for a first phase; a plurality of components for a second phase; and a plurality of components for a third phase. The plurality of components for the first phase, the second phase, and the third phase each include a connection to a main busbar, a circuit breaker actuator, a single phase circuit breaker pole, and a cable connection. The circuit breaker actuator and the single phase circuit breaker pole for the first phase are oriented along a first axis. The circuit breaker actuator and the single phase circuit breaker pole for the second phase are oriented along a second axis. The circuit breaker actuator and the single phase circuit breaker pole for the third phase are oriented along a third axis. The first axis, the second axis, and the third axis are inclined.

Systems, methods, techniques and apparatuses of contactors are disclosed. One exemplary embodiment is a contactor including an electric pole, a pair of plungers, and a pair of opening springs. The electric pole includes a fixed yoke member and a movable yoke member arranged respectively at a proximal position and a distal position with respect to a movable contact. The fixed yoke member includes a pair of through holes. The pair of second plungers are inserted in a corresponding through hole passing through the fixed yoke member and symmetrically positioned with respect to a main symmetry plane of the contactor, which is parallel to a displacement axis of the movable contact and perpendicular to a displacement plane of the movable contact. The pair of opening springs are symmetrically positioned with respect to the main symmetry plane.
