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).

| 49 | Operation selector for switchgear | US705442 | 1996-08-29 | US5808251A | 1998-09-15 | Buddy B. McGlone |
| An operation selector arrangement is provided for an operating mechanism that is controlled by movement of an operating shaft between the operational positions. Blocking features are provided for preventing operation between predetermined operational positions without first manipulating the blocking features. In a preferred arrangement, a an operating handle is utilized to operate the operation selector arrangement. A blocking member prevents operation of an operation selector between two operating positions without first stopping at an intermediate position, removing the operating handle, moving the blocking member, and then reinserting the handle. The blocking member is separately securable from the operation selector such that personnel may be authorized to operate the operation selector while other personnel are additionally authorized to manipulate the blocking member. | ||||||

| Safety apparatus for disconnecting overhead electrical switches for maintenance, comprising an insulated rod having an upper disconnect hook to engage a handle of a switch box and move it from an on position to an off position in which power is disconnected, an arm attached to the rod and cooperating with the hook to secure the switch handle in the off position, and a locking device connected to the arm and to the rod to prevent inadvertent movement of the switch handle to the on position. | ||||||
| 51 | Locking arrangement for disconnect switch | US852469 | 1992-03-17 | US5268543A | 1993-12-07 | Joel A. Ramos |
| An arrangement for locking the disconnect linkage of a high-voltage switch is provided that includes two relatively movable locking members that are each moved between locked and unlocked positions in response to operation of the disconnect linkage. As the disconnect linkage is moved to an opened position, the two locking members are moved into relative overlapping alignment to receive a blocking member to prevent movement of the disconnect linkage. One locking member is carried by the disconnect linkage and the second member is carried by a pivotally mounted support arm that is affixed to the disconnect linkage so as to move therewith. Accordingly, the second locking member does not encroach on the space adjacent the disconnect linkage except when it is moved into alignment in the opened position. The support arm that carries the second locking member is arranged to guide the disconnect linkage and prevents undesirable movement of the disconnect linkage due to transverse forces on the disconnect linkage during movement between the opened and closed positions. | ||||||
| 52 | Manually operable circuit breaker | US516269 | 1990-04-30 | US5168137A | 1992-12-01 | Friedrich Hufnagel; Georg Weidner |
| A manually operable circuit breaker having coupling terminals and a visible isolating gap which can be established only when the protective circuit breaker is open. The isolating gap is provided by an isolating module which is mountable on coupling terminals of the circuit breaker. The isolating module contains a removable isolating unit. The isolating unit can be removed only when the protective circuit breaker is open. In this way, the circuit breaker is provided with a visible isolating gap only when required. | ||||||
| 53 | Switchgear with fuses individually mounted on fuse carriers and switches therefor for interlocks | US3790861D | 1972-10-10 | US3790861A | 1974-02-05 | SAKATS G |
| High voltage fuses are mounted on individual carriers for movement into and out of engagement with stationary contacts under the control of a carriage that can be connected to any or all of the carriers. Switches are arranged to connect any or all of the fuses in circuits. A locking bolt holds each fuse carrier in closed position and can be moved to locking position only when the fuse carrier is closed. Interlocks between the fuse carriers and operators for the switches prevent opening the carrier when the switches are closed and closure of the switches when the carriers are open.

| 54 | Locking mechanism | US3748621D | 1972-09-25 | US3748621A | 1973-07-24 | SAKATS G |
| A locking mechanism for a removable roller mounted fuse drawer of a high voltage fuse enclosure. Locking levers are mounted on a first shaft adjacent loadbreak connectors so that when the loadbreak connectors are connected to fuse terminals they engage blocking levers causing the levers and shaft to pivot. The shaft is interconnected by a linkage arrangement to a second shaft adjacent the roller mounted fuse drawer. Mounted on the second shaft are blocking cams which engage stops on the fuse drawer to prevent movement of the fuse drawer when the loadbreak connectors are connected. When the loadbreak connectors are manually disconnected from the fuse terminals breaking the circuit to the fuses, the blocking levers and first shaft pivot causing the linkage arrangement to rotate the second shaft and move the blocking cams out of engagement with the drawer stops thus permitting the fuse drawer to be removed from the fuse enclosure. The fuse drawer can then be removed so that the fuses can be tested or replaced. The blocking cams prevent replacement of the fuse drawer in the fuse enclosure if any of the loadbreak connectors are reconnected to the fuse terminals after the fuse drawer is removed from the fuse enclosure. Thus, the fuse drawer can neither be opened nor closed any time a loadbreak connector is connected to the circuit thus preventing either opening of the fuse drawer when the fuses are under electrical load or closing the fuse drawer into an electrically loaded circuit.

| 55 | Transformer station carried by a mast | US3706839D | 1971-12-09 | US3706839A | 1972-12-19 | COMTE BERNARD; CLER VICTOR |
| The invention relates to a transformer station carried by a mast. Such a station comprises a transformer and a high voltage connection device last fastened onto the mast the one above the other. A low voltage connection device is located within the hollow mast. An access device to the high voltage circuit-breaker is provided and comprises a ladder, the lower portion of which is foldable, a footbridge surrounded by a hand rail. The station is remarkable in that it comprises further a safety device hindering the unfolding of the ladder as long as the high voltage line as well as the primary of the transformer has not both been grounded.

| 56 | Enclosure for pad mounted electrical switchgear having sliding top and end panels | US3573561D | 1969-09-16 | US3573561A | 1971-04-06 | BEEBE EMMETT R |
| Metallic housing for pad-mounted high voltage switches and fuses has sliding top panel which must be shifted forward or back to permit removal of back and front sliding access panels. A lock prevents movement of the top panel from overlying relation to the front and rear panels. Fuses are mounted in a drawer which is locked closed and can only be opened when the lock under the top panel is uncovered. Access to the manual operator for the switch assembly or assemblies is accessible only when the top panel is shifted back. A mechanical maze construction between exposed movable panels reduces likelihood of entrance of wire and the like.
