Title:
CIRCUIT BREAKER HAVING PLURALITY OF CONTACT PIECES
Document Type and Number:
Japanese Patent JP2018142538
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To more effectively and quickly eliminate an ark which can be formed in a gap between contact pieces of a circuit breaker.SOLUTION: A circuit breaker 100 comprises at least two group contact pieces which are electrically connected in serial. When disconnecting the at least two group contact pieces, the circuit breaker is disconnected at the same time. Since a distance between the contact pieces of each group connected in serial is accumulated, the distance between the contact pieces of each group is increased. Then, an arc voltage which effectively breaks the connection than any arc which can be formed between the contact pieces of each group is increased. The contact piece is constructed so that a slide operation in a lateral direction for removing fragments or contaminants on a surface by "wiping" a correspondent contact surface occurs when the contact pieces are closed.SELECTED DRAWING: Figure 1
