摘要： PROBLEM TO BE SOLVED: To provide a breaker capable of preventing deterioration of a PTC current-limiting device, of preventing a previously opened switch from being closed again, and of easily transferring a fault current to the PTC current-limiting device side.
SOLUTION: This breaker includes: a first switch; a second switch connected to the first switch in parallel; the PTC current-limiting device 44 connected in series to the second switch and in parallel to the first switch; a movable arm 50 opening/closing the first and second switches; a fixed arm 40 including a first fixed arm conductor part 54 for guiding for guiding current flow toward the first fixed contact 46 in a normal load current mode and a second fixed arm conductor part 48 for guiding current flow toward the second fixed contact 52 via the PTC current-limiting device 44 in a fault current mode; and a successive trip means for elastically biasing the second switch by operation of the movable arm 50 in a closing direction and successively tripping the first and second switches using time taken for releasing the elastic bias of the second switch when the movable arm 50 is operated in a tripping direction.

摘要： PROBLEM TO BE SOLVED: To provide a partial discharge sensor that facilitates manufacture and has wide band characteristics by forming a partial discharge signal detecting pattern for detecting a partial discharge signal inside a gas insulated apparatus on a PCB (printed circuit board) substrate. SOLUTION: The partial discharge sensor includes the PCB substrate, a partial discharge signal detection pattern that is molded on the PCB substrate and detects the partial discharge signal inside the gas insulated apparatus, and a coupling terminal that receives the partial discharge signal detected by the partial discharge signal detection pattern and transmits the partial discharge signal to a connector for pulling it to the outside. The partial discharge sensor is attached to the inner wall of an outer box of the gas insulated apparatus. COPYRIGHT: (C)2010,JPO&INPIT
