Current transformer connector in faulty current trip - uses coupling lines to protective circuit breakers on which transformer is inserted

摘要

The connection uses connecting lines (4, 4a) to protective circuit breakers and clamping terminals (5) on the latter. Wires are used for this purpose, which are mounted on the respective breaker or on the clamping terminals. Their free ends extend into the transformer space (3). The transformer is inserted on the incoming or outgoing wire ends, or on a metal bridge (3a, b), while the latter provides the wire ends interconnection. The bridge is preferably made of a copper strip with circular holes (6a) at its ends, into which are inserted the wire ends of rectangular cross section in a self-locking manner.
