Abstract:
The disclosed concept pertains to systems and methods to control the passing or entering of a circuit breaker into a cell. The concept relates to employing a RFID-actuated circuit breaker coding interlock. The interlock includes a circuit breaker having a RFID tag that stores information relating to the circuit breaker and a cell structured to receive the circuit breaker. The cell includes a blocking mechanism moveable between a blocking condition which prevents insertion of the circuit breaker into the cell and a non-blocking condition which permits insertion of the circuit breaker into the cell, and an RFID reader module structured to wirelessly receive the information from the RFID tag and determine whether to move the blocking mechanism from the blocking condition to the non-blocking condition based on the information.
Abstract:
A vacuum circuit breaker includes a frame and a vacuum interrupter supported by the frame. A control wiring harness exits from an opening in a top face of a housing portion of the frame and a terminal block is disposed on the top face of the housing portion and includes first terminals connected to wires of the control wiring harness and second terminals configured to be connected to external wires.
Abstract:
A fuse operation indicator assembly includes an elongate tube having first and second ends, a fuse striker receiving member at the first end of the tube and configured to receive a fuse striker, an actuating member at the second end of the tube and configured to be actuated responsive to the fuse striker member, and a detector configured to detect actuation of the actuating member.
Abstract:
The present disclosure provides a conductive member for a circuit breaker high voltage portion conductor assembly, the conductive member including a body with a transfer portion and a coupling portion. The body transfer portion has an electro-thermally efficient contour. That is, the body transfer portion has an electrically efficient contour and a thermally efficient contour. The body transfer portion includes a number of slots defining fins. In this configuration, the body transfer portion distributes current generally evenly across a cross-sectional area of the conductive member body. Further, the fins provide heat dissipation via convection.
Abstract:
A grounding and test device includes a chassis configured to be removably installed in a drawout switchgear compartment (e.g., a breaker compartment) having a load conductor and a line conductor therein. The device also includes an interconnection bus supported by the chassis and a ground conductor supported by the chassis. The device further includes a first vacuum circuit interrupter supported by the chassis and configured to selectively couple and decouple the interconnection bus and the line conductor, a second vacuum circuit interrupter supported by the chassis and configured to selectively couple and decouple the interconnection bus and the load conductor and a third vacuum circuit interrupter supported by the chassis and configured to selectively couple and decouple the interconnection bus and the ground conductor.
