摘要： The invention relates to a center break switch having a contact system for electrical current conduction and bus transfer switching. The contact system includes two moving contacts. One of the two moving contacts includes a finger contact and the other moving contact includes a first contact. Each moving contact includes a contact for bus transfer switching, wherein one of the two contacts includes a spherical contacting element, and the other contact includes a rectangular contacting element. The spherical contacting element and the rectangular contacting element engage during switching for the bus transfer, and stay in contact when the finger contact is engaged with the first contact for electrical current conduction.

摘要： A pole assembly of a switching device is provided. The pole assembly includes a first interrupter unit operably connected to a pole plate of the pole assembly via first post insulators. The first interrupter provides a path for current flow through the first interrupter in a closed state and interrupts the current flow in an open state. A second interrupter unit is operably connected to the first interrupter unit and to the pole plate via second post insulators. The second interrupter allows the current flow through the first interrupter unit in an open state and grounds the switching device in a closed state. The pole assembly includes a dielectric shield physically disposable between and operably connected to the first post insulators and the second post insulators for uniformly distributing an electric field generated during operation of the pole assembly.

摘要： In one embodiment, a fuse cutout cover has an integral roof portion. The roof portion covers the energized top of a fuse in a first type of cutout. An attachable roof extension covers the energized top of a fuse in a larger second type of cutout, such as a Fault Tamer™ cutout. By adding the roof extension, the same cover may be used with two types of cutouts, and there is not a large gap over the fuse, preventing wildlife from entering the gap. In another embodiment, a second roof is formed over the first roof portion to accommodate different types of cutouts. Electrical insulation between wildlife and the energized cutout is also increased.

摘要： A communication system controlled motorized in-line high voltage air break disconnect switch with a lock out system including a communication device remote controlled lock out. Also a mechanical lock out is provided if a battery that powers the remote controlled lock out is not functioning or other unforeseen problems cause a failure of the switch or the remote controlled lock out to operate. The remote controlled lock out when operative can prevent the switch from operating the motor when the remote controlled lock out is actuated. The motorized switch typically includes the motor having a worm drive shaft carrying a hookstick eye ring. The remote controlled lock out includes a locking gear mounted on the drive shaft. A lockout lever having a locking tooth is provided that engages or disengages the locking gear when appropriately actuated by the remote control to lock or unlock the switch blade drive motor.

摘要： A high voltage in-line air break disconnect switch suspended by an electric power line conductor wherein the switch includes a rotating switch blade that is operated by a communication system controlled motor that may include a switch mounted radio which may be controlled by another radio located at a distance and powered by a solar charged battery. The communication system controlled motorized in-line air break disconnect switch may also be arranged in a three phase installation in a two-way or three-way switching arrangement attached to a utility pole or other structure. The communication system controlled motorized in line air break disconnect switch may in addition be arranged in a phase over phase switching arrangement supported by a utility pole or other structure.

摘要： An isolating ground switch includes an enclosure with a frontal surface. A slide channel opens through the top of the enclosure. A conductive switch plate is received in the channel and is bi-directionally slidably positionable between the first position and the second position. A plurality of terminal studs project forwardly from the frontal surface of the enclosure and rearwardly conductively communicate with a conductive portion. When the switch plate is in the first position, the conductive portion engages the switch plate. When the switch plate is in the second position, the conductive portion is isolated from the switch plate.

摘要： The circuit breaker system contains a plurality of phase conductors, a circuit breaker having a plurality of breaker poles, and a short-circuit link having a star point and a plurality of link conductors combined at the star point. Each of the phase conductors is electrically conductively connected to in each case one of the breaker poles and each link conductor is electrically conductively connected to in each case one of the phase conductors in each case one of several first disconnectors to which short-circuit current can be applied. In order to avoid expenditure on assembly and downtimes of the circuit breaker system when carrying out simulation experiments with the aid of the short-circuit link, the circuit breaker system contains a second disconnector which, when closed, electrically conductively connects the star point to ground and which is opened when a short-circuit current is applied to the short-circuit current link.

摘要： A portable load-breaking and pickup apparatus for handling a load associated with a power distribution system is disclosed. The apparatus includes first and second spaced-apart connectors electrically connected by a load break assembly. The load break assembly includes first and second outer contacts configured for mating engagement and configured to provide a low-resistance path between the first and second connectors, and first and second inner contacts configured for mating engagement and configured to provide a high-resistance path between the first and second connectors. The load break assembly transitions from an open position to a closed position in two stages. The two stages include closing the high-resistance path prior to closing the low-resistance path, and closing the low-resistance path after the high-resistance path has been closed.
