SWITCH
Document Type and Number:
Japanese Patent JP2016081853
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a switch capable of preventing inter-phase short-circuiting by suppressing formation of an open hole on an inter-phase wall.SOLUTION: Switch parts 2a, 2b and 2c comprise: stationary contactors 3a, 3b and 3c including stationary contacts 20a, 20b and 20c; movable contactors 4a, 4b and 4c including movable contacts 18a, 18b and 18c which are brought into contact and non-contact with the stationary contacts; arc runners 5a, 5b and 5c for driving an arc generated between the stationary contact and the movable contact with an electromagnetic force; and an arc cover 6 for covering the stationary contacts, the movable contacts and the arc runners. The switch parts are disposed in a three-phase parallel manner. The arc cover includes an inter-phase wall 7 separating the switch parts which are disposed in the three-phase parallel manner. A direction in which the arc of the switch part 2b disposed in the center is different from a direction in which the arcs of the switch parts 2a and 2b disposed at both sides are driven.SELECTED DRAWING: Figure 1
