摘要： An electromagnetic actuator is capable of providing a high speed driving force, for example, for driving the contacts of a circuit breaker or similar power distribution equipment. The electromagnetic actuator may use a directly powered moving coil element in combination with one or more energized stationary coils to generate an output force using reduced requirements for current, voltage and current/voltage rate-of-change. Precise control of actuator motion is obtained by permitting different supply voltages, firing times and capacitor supplies. The electromagnetic actuator may further incorporate a return spring arrangement and a magnetic latch arrangement.

摘要： A circuit testing closer may include a fault isolating switching device coupled between a supply side and a load side of a power distribution system and a current pulse generator coupled in parallel to the switch to generate a current pulse within the power distribution system subsequent to a fault isolation for testing the power distribution system. The current pulse generator may include an electromechanical actuator, an electromagnetic actuator or a solid state switching device. The circuit testing closer may be a purpose-built combination device, or the fault isolating switching device and the current pulse generator may be separately coupled and commonly controlled devices. The fault isolating switching device may have continuous current rating greater than a continuous current rating of the pulse generating device.

摘要： A manual trip control method and arrangement is provided to manually trip a plurality of circuit interrupters. Specifically, where the circuit interrupters include magnetic-actuator-driven vacuum interrupters including permanent magnets that hold the contacts of the circuit interrupter in the closed position via a plunger, a first of the circuit interrupters is manually tripped via movement of the plunger. To operate the remaining circuit interrupters to trip open, the voltage generated in the magnetic actuator of the first circuit interrupter is coupled to the magnetic actuators of the remaining circuit interrupters for tripping thereof.

摘要： A multi-path switching configuration provides independent switching of multiple circuit paths. In a preferred arrangement, a plurality of circuit interrupters have one end connected in common with each other and a second end providing a circuit path connection. An operating facility is arranged to independently operate the circuit interrupters via an operating member operatively connected to a respective circuit interrupter and controlling the respective interrupting path. Two or more of the operating members are moved to selectively provide desired connections of circuit paths.
