| Sequential operation of a pair of switches in a required sequence of operation is ensured by means of a telescoping arrangement of tubes which are connected to associated ones of switch operating shafts. A positive stop prevents the movement of one telescoping member relative to the other out of sequential order. | ||||||

| 24 | Device for locking an item of switchgear, particularly for grounding disconnectors of electrical lines, with high safety against unauthorized actuation | EP06009531.2 | 2006-05-09 | EP1748454A3 | 2008-03-19 | Bossi, Daniele; Bre', Romano |
A device for locking an item of switchgear, particularly for grounding disconnectors of electrical lines, with high safety against unauthorized actuations, comprising an abutment element (2), which is connected to the item of switchgear (3) to be locked and can move along a path in order to pass from at least one first position to at least one second position, these positions being mutually spaced along the path, or vice versa. The device comprises first locking means (4), which can engage the abutment element (2) in order to lock it in the two mentioned positions, and control means (5) for disengaging the first locking means (4) from the abutment element (2). The first locking means (4) comprise a calibrated-shear element (6) adapted to allow, following its breakage, the passage of the abutment element (2) from the first position to the second position without acting on the control means (5). The device comprises second locking means (7), which can engage the abutment element (2) in order to lock it in the second position despite the breakage of the calibrated-shear element (6).

| A fastener is provided for ganging or joining two or more switch handles to one another. The fastener includes a head at one end and an elongated shank extending from the head. The shank includes a threaded portion adjacent the head that threadingly engages one of the switch handles. The shank extends longitudinally from the threaded portion through the threadingly engaged switch handle and through one or more additional switch handles to gang the switch handles to one another. | ||||||
| 27 | Automatic sectionalizing system | US142433 | 1980-04-21 | US4345291A | 1982-08-17 | Richard E. Riebs |
| This invention relates generally to underground electric power distribution systems. In particular, it relates to underground loop feed circuits which include reclosers and transformers and a plurality of high frequency actuated normally closed isolator switches for automatically locating and sectionalizing portions of the loop circuit in which faults originate. The actuator switches between which a fault occurs are armed in response to a fault current and only those switches which are armed are opened thereby isolating the faulted section of cable. The remaining actuator switches remain closed. | ||||||

| This invention refers to a kind of embedded-pole high voltage electrical apparatus combination switchgear with a function of a five prevention interlock, which is custom-designed for technical issues of low degree of integration and modularization of like products. It consists of an EP bracket, an EP spring operating mechanism and disconnecting earthing switchgear. Three EPs in one row are set in the bracket. The spring operating mechanism and disconnecting earthing switchgear integrate by chamber an interlock unit and a mechanism interlock unit. The chamber interlock unit, the mechanism interlock unit and a chamber lock plate form an integrative unit. The chamber lock plate is opposite to the buckle of the opening half shaft of the spring operating mechanism and is equipped with chamber lock pin. The chamber interlock unit moves up and down to open or close the operating crank hole of the disconnecting earthing switchgear, and corresponds to the closing operation and limit closing driven by buckle of closing half shaft and the limit and opening of opening half shaft and cable chamber. | ||||||
