Title:
CONNECTION PHASE DISPLAY MECHANISM FOR PLUG-IN BREAKER
Document Type and Number:
Japanese Patent JP2015154696
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology capable of specifically identifying a connection phase of a plug in a plug-in state, in a plug-in breaker capable of changing the connection phase of the plug by rotating a plug at the side of a power source.SOLUTION: A connection phase display mechanism for a plug-in breaker is capable of changing connection phases with bus bars stacked over three stages in a vertical direction by rotating plug terminal fittings 2 and 3 which are disposed at two upper and lower positions at the side of a power source. The connection phase display mechanism includes: position detection means 6 and 7 for detecting the presence of the plug terminal fittings at the positions in the cas where the plug terminal fittings 2 and 3 are disposed at positions to be connected with bus bars on two stages among the bus bars stacked over the three stages in the vertical direction; a determination section 9 which receives detection results of the position detection means as electrical signals and determines the connection phase of the plug-in breaker in accordance with a combination pattern of the signals; and display means 10 for electrically displaying a determination result of the determination section.
