| 20080296137 | ELECTRICAL SWITCHING APPARATUS AND STORED ENERGY ASSEMBLY THEREFOR - A stored energy assembly is provided for an electrical switching apparatus, such as a circuit breaker. The stored energy assembly includes a mount removably coupled to the circuit breaker housing. A stored energy mechanism, such as a spring, is coupled to the mount and is movable among charged and discharged positions. An actuating element is cooperable with the gears of a gear assembly in order to move among first and second positions corresponding to the spring being disposed in the charged and discharged positions, respectively. A manual charging mechanism and an automatic charging mechanism are coupled to the gear assembly, and move the gears, in order to move the actuating element and charge the spring. The spring, the actuating element, the gear assembly, and the charging mechanisms are coupled to the mount, thereby forming a sub-assembly. The sub-assembly is removably coupled to the circuit breaker housing. | 12-04-2008 |
| 20080296138 | ELECTRICAL SWITCHING APPARATUS, AND STORED ENERGY ASSEMBLY AND TIME DELAY MECHANISM THEREFOR - A time delay mechanism is provided for a circuit breaker stored energy assembly including a mount, a spring coupled to the mount, at least one charging mechanism for charging the spring to store energy, at least one actuator for releasing the stored energy, and a drive assembly for transferring the stored energy into movement of the circuit breaker operating mechanism. First and second trip shafts of the time delay mechanism are pivotably coupled to the mount. Linking elements interconnect the first and second trip shafts. A trip catch and a drive lever are coupled to the first trip shaft. The linking elements and a damper, which is connected to the drive lever, contribute to a delay from a first time that the first trip shaft initially moves, to a second time that the second trip shaft moves to release the trip catch. The damper is adjustable to adjust the delay. | 12-04-2008 |
| 20090200270 | ENCAPSULATED POLE UNIT CONDUCTOR ASSEMBLY FOR AN ENCAPSULATED POLE UNIT AND MEDIUM VOLTAGE CIRCUIT INTERRUPTER INCLUDING THE SAME - A medium voltage circuit interrupter includes a circuit interrupter housing and a plurality of poles. Each of the poles includes an encapsulated pole unit. The encapsulated pole unit includes a first unit having a first conductor, a second conductor, a vacuum interrupter electrically connected between the first conductor and the second conductor, and a first housing housing the vacuum interrupter. A removable second unit includes a third conductor, a fourth conductor having a first portion electrically connected to the third conductor and a second portion removably electrically connected to one of the first conductor and the second conductor, an electronic device structured to sense a characteristic of the pole, and a second insulative housing encapsulating the third conductor, the first portion of the fourth conductor and the electronic device. An operating mechanism is structured to open and close the vacuum interrupter of each of the poles. | 08-13-2009 |
| 20100283487 | SYSTEM AND METHOD FOR SENSING VOLTAGE IN MEDIUM-TO-HIGH VOLTAGE APPLICATIONS - A system and method for measuring voltage of a medium to high voltage line conductor is disclosed. The system includes an electrical insulator having a surface and an edge, the surface having an opening therein to allow passage of a line conductor therethrough in a direction generally perpendicular to the surface. The system also includes first and second electrodes positioned about the opening on the surface of the electrical insulator and spaced apart from one another to provide a common capacitive divider signal indicative of a voltage potential of the line conductor. | 11-11-2010 |
