20150101915 | HIGH VOLTAGE SWITCH BLADE CLOSING DETECTOR - A blade closing detector for an electric power switch includes a blade closing detector and an electronic or visual indicator. A first type of detector uses a gravity switch and a magnetic pickup to detect proper engagement between the blade and the switch. A second type of detector uses a sliding latch with a visual indicator rod to provide a visual indication of proper engagement of the blade within the jaws. A third type of detector uses a magnetic switch with a pivot arm and a dome shaped visual indicator. These detectors may be deployed individually or in combination and may be augmented with communication equipment to transmit switch status to a remote location. It will be understood that specific embodiments may include a variety of features in different combinations, as desired by different users. | 04-16-2015 |
20140160612 | INTEGRAL CURRENT TRANSFORMING ELECTRIC CIRCUIT INTERRUPTER - An electric power switch suitable as a capacitor, line and load switch for transmission and distribution voltages includes an external actuator controlled by current transformers (CTs) mounted on live tanks comprising insulators forming dielectric containers that house the contactors of the switch. The CTs are located on the outside of the insulators in the regions of the insulators overlying the internal contactors between the upper and lower high voltage line taps. The actuator and controller may also be located outside the dielectric container, as desired. This configuration minimizes the size of the dielectric container and removes the severe size constraint inherent in design conventional “live tank” switch designs, while also avoiding the need for separate line-mounted CTs. This design also avoids the need for a separate grounded “dead tank” to house the CTs, which are more conveniently located in the outside of the insulators. | 06-12-2014 |
20140158665 | SEALED SOLENOID MAGNETICALLY OPERATED HIGH VOLTAGE ELECTRIC POWER SWITCH - A sealed solenoid, magnetically operated electric power switch is suitable for use as capacitor, line and load switch operating at transmission and distribution voltages that includes no seals through the sealed container housing the contactor portion of the switch. The sealed solenoid switch includes a magnetically operated drive system with an actuator that magnetically couples across the container wall to avoid the use of a moving or sliding seal as part of the drive system. The sealed solenoid switch may also include a ballast resistor and resistor contact located inside the sealed container to avoid another seal as part of the ballast system. A magnetic latch holds the switch in a closed position, and a spring holds the switch in the closed position, to avoid the need for an energizing current to maintain the switch in either position. | 06-12-2014 |
