PURPOSE: To obtain a rectifying-element replacement apparatus by which the replacement operation of a stacked rectifying element is performed easily by a method wherein an element support device is moved up and down and a specific rectifying element and a cooling body which is situated on its lower side are coupled or separated. CONSTITUTION: When a stacked rectifying element 21 is to be taken out, a rectifying-element replacement apparatus 30 in a state that an element support device 32 has been lowered is placed on the surface of a cooling body 22 so as to be pushed, and a prescribed fin 21a at the rectifying element 21 is sandwiched and held by a support part 32a. When a lift device 31 is pushed by a handle 31e in this state, a pin 32b is slid inside a horizontal groove part at a support groove 31b, it is pushed up to the top part when it reaches a groove part in the vertical direction, the element support device 32 is raised, and the rectifying element 21 can be taken out. In addition, when the rectifying element is to be inserted and stacked, a positioning device 33 is inserted into a groove part 31d at the lift device 31, it is slid on the face of the cooling body 22 so as to be pushed, and a block 36g is set to a housed state at the inside. Then, the cooling body 22 is lowered by its own weight, it pushes down the rectifying element 21, a pinhole 21b is inserted into a pin 22a, and the stacking of the rectifying element is completed. Consequently, the replacement operation of the rectifying element can be performed easily. |
