DISTRIBUTION APPARATUS

Document Type and Number:

Japanese Patent JP2017045518

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a distribution apparatus capable of preventing members from being damaged by overrun of a movable electrode during submerging.SOLUTION: A circuit breaker comprises: a stationary electrode 107; a movable electrode 114 which is rotatable relatively to the stationary electrode 107; and an arc extinguishing chamber 130 including an opening part 133 which covers the stationary electrode 107 and through which the movable electrode 114 can be inserted. The circuit breaker is closed by bringing the movable electrode 114 into contact with the stationary electrode 107 and opened by separating the movable electrode 114 from the stationary electrode 107. The circuit breaker comprises a buffer member 140 which is fitted to an upper support insulator 104 and provided on an extension of a movable range of the movable electrode 114. The buffer member 140 is provided at such a position that the buffer member collides with the movable electrode 114 in the case where the movable electrode 114 is at least over a contact position where the movable electrode is in contact with the stationary electrode 107 during submerging. Therefore, members can be prevented from being damaged by overrun of the movable electrode 114 during submerging.SELECTED DRAWING: Figure 2
