UNIT STORAGE DEVICE

摘要

In order to simplify an operation when exchanging a circuit unit, this unit storage device (1) for storing the circuit unit (101) of a semiconductor power conversion device (100) is provided with: a cart (10) having a mounting base (11) on which the circuit unit (101) is mounted; a cage (20) having an insertion/removal opening (24) which makes it possible to insert and remove the cart (10) while the circuit unit (101) is mounted on the mounting base (11); and a cart-immobilizing member (26) for detachably immobilizing the cart (10) in the cage (20).
