ON-LOAD TAP CHANGER
Document Type and Number:
Japanese Patent JP2015106582
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an on-load tap changer with high rigidity that rarely generates distortion or deformation.SOLUTION: An on-load tap changer is installed in a tank of a transformer body, and has an oil tank housing a changeover circuit breaker and filled with insulation oil inside, and a tap selector arranged under the oil tank. The changeover circuit breaker 3 comprises a shaft, a first plate-like member, a second plate-like member, a third plate-like member, and a support member. An energy-storing mechanism rotatably supported by the shaft and generating a rotation force at the time of tap changing is located on the first plate-like member. A source flow resistance rotatably supported by the shaft for flowing different current by changing the tap is located on the second plate-like member. A breaking mechanism rotatably supported by the shaft for breaking the current is located on the third plate-like member. The support member fixes the first plate-like member, the second plate-like member, and the third plate-like member in contact with a side edge of each plate-like member from a side.
