CURRENT LIMITING CIRCUIT BREAKER WITH ELECTROMAGNETIC OPENING MEANS |
摘要 |
<p>CURRENT LIMITING CIRCUIT BREAKER A circuit breaker includes a slotted magnetic device having a plurality of spaced slotted conductive plates and a moving contact arm positioned within the slot when the circuit breaker is in a closed circuit position so that current flowing through the contact arm has a component in a vertical direction with respect to the slot. An overcurrent condition through the circuit breaker causes magnetic flux to be generated within the slotted magnetic device which develops a force to drive the moving contact arm from the front to the rear of the slot in a direction generally parallel to the bottom of the slot, thereby actuating the circuit breaker from a closed circuit position to an open circuit position. The circuit breaker also includes an arc-extinguishing device including a plurality of apertured conductive plates. The moving contact arm includes a probe member extending into the apertures of the plates when the circuit breaker is in a closed circuit position.</p> |
