摘要： A circuit breaker includes a frame and first, second and third single-phase vacuum interrupters and first, second and third magnetic actuators connected to respective single-phase vacuum interrupters. Each of said magnetic actuators is configured to receive an open or close signal and in response, actuate the respective vacuum interrupter connected thereto into an open or closed circuit condition. Each magnetic actuator includes a fixed core, a plurality of permanent magnets surrounding the fixed core, and a movable core received within the fixed core. A controller is connected to each of the first, second and third magnetic actuators and generates the open or close signal to a respective magnetic actuator to open or close one or more of the first, second and third single phase interrupters.

摘要： A circuit breaker includes a frame defining a housing having an interior compartment and a circuit interrupter. An actuator is connected to the circuit interrupter and configured to actuate the circuit interrupter into closed and open breaker positions. An indicator is connected to the actuator and movable between first and second positions corresponding to the respective closed and open breaker positions. A first indicator surface has first indicia indicative that the circuit interrupter is in the closed breaker position and a second indicator surface having second indicia indicative that the circuit interrupter is in the open breaker position. An opening is formed on the housing and aligned with the indicator to expose for view the respective first or second indicia when the circuit interrupter is in the respective closed or open breaker position.

摘要： A circuit breaker may include a first magnetic actuator connected to a first single-phase vacuum interrupter, a second magnetic actuator connected to a second single-phase vacuum interrupter, and a third magnetic actuator connected to the third single-phase vacuum interrupter. Each magnetic actuator is configured to receive an interrupt signal, and in response, actuate a respective vacuum interrupter connected thereto into an open circuit condition. Each magnetic actuator includes a fixed core, a plurality of permanent magnets surrounding the fixed core, and a movable core received within the fixed core. A controller generates an interrupt signal to a respective magnetic actuator and interrupts one or more of the first, second and third single-phase vacuum interrupters.

摘要： A medium-voltage switchgear system includes a three-phase circuit breaker having first, second and third single-phase vacuum interrupters connected between respective first, second and third single-phase inputs and first, second and third single-phase outputs. Magnetic actuators are connected to first, second and third single-phase vacuum interrupters, which are configured to receive an interrupt signal and in response, actuate the respective vacuum interrupter connected thereto into an open circuit condition. A controller circuit is connected to each of the first, second and third magnetic actuators and generates an interrupt signal in response to a detected single-phase overcurrent or fault on a single-phase circuit and interrupt that single-phase circuit on which the single-phase overcurrent or fault occurred and maintain power on the remaining two single-phase circuits over which a single-phase overcurrent or fault was not detected.

摘要： A switchgear system includes a switchgear frame and a truck carrying a circuit breaker, which includes a breaker housing, a fixed electrical contact and a movable electrical contact mounted within the breaker housing, an actuator piston connected to the movable electrical contact, and a drive assembly coupled to the actuator piston. A sensor circuit is mounted on the switchgear frame under the truck and aligned with the circuit breaker and configured to acquire displacement data of the actuator piston when in a contact testing position. A controller is coupled to the sensor circuit and configured to receive the displacement data and determine electrical contact erosion within the circuit breaker.

摘要： A testing system includes a truck carrying a circuit breaker, a fixed contact, and an actuator piston connected to a movable contact. A test platform supports the truck in a contact testing position and includes a sensor circuit mounted on the test platform and positioned under the truck and aligned with the circuit breaker when the truck is on the test platform in the contact testing position. The sensor circuit is configured to acquire displacement data of the actuator piston when the movable electrical contact is moved between the open and closed positions. A controller is coupled to the sensor circuit and configured to receive the displacement data and determine electrical contact erosion within the circuit breaker.

摘要： An X-ray radiation imaging system is for imaging an object. The X-ray radiation imaging system may include an X-ray source device configured to irradiate the object with X-ray radiation, an X-ray detector to be positioned adjacent the object and having a carrier layer, and X-ray sensing segments carried by the carrier layer and defining a sensing array. The X-ray sensing segments may receive the X-ray radiation through the object. The X-ray radiation imaging system may include an image extraction device configured to generate an image of the object based upon the X-ray detector.
