Abstract: An uninterruptible power supply includes a plurality of uninterruptible power supply modules each including a power converter, an input/output module that outputs power converted by the power converter to an outside of the uninterruptible power supply, and a disconnection module including a housing that houses disconnection switches that electrically disconnect each of the plurality of uninterruptible power supply modules individually.

Abstract: An uninterruptible power supply includes disconnectors that perform a disconnection operation to electrically disconnect a plurality of uninterruptible power supply modules individually. Each of the disconnectors includes a connection conductor that electrically connects a first conductor to a second conductor, and a moving member mechanically moving the connection conductor in a direction in which the connection conductor approaches and contacts the first conductor and the second conductor, and a direction in which the connection conductor is spaced away from the first conductor and the second conductor.

Abstract: In an uninterruptible power supply, first connection members that connect input side-switches of a plurality of uninterruptible power supply modules to each other and that connect output-side switches of the plurality of uninterruptible power supply modules to each other, and second connection members connected in parallel to the first connection members are disposed at positions accessible from a front side of the uninterruptible power supply modules.

Abstract: A power converter includes a component compartment in which heat-generating components are housed, a duct for exhausting heat generated by the heat-generating components away from the component compartment, and a partition arranged between the component compartment and the duct in order to divide apart the component compartment and the duct. Outlets having sizes corresponding to the amounts of heat generated by the heat-generating components are formed in the partition.

Abstract: An uninterruptible power supply includes an input switch, an input filter, and a power converter disposed in this order, an output filter and an output switch disposed in this order from the power converter, and a plurality of conductors that connects the input switch, the input filter, the power converter, the output filter, and the output switch to each other in this order.

Abstract: A power converter includes a mounting shelf arranged above or on a bottom plate. On the mounting shelf, a unit including wheels on a bottom surface is mounted removably in a front-rear direction. The power converter further includes a housing. The housing includes a pair of attachment portions respectively arranged on front edges of a pair of left and right side plates. The power converter further includes a protective cover. The protective cover is configured to secure the unit removably mounted on the mounting shelf between the pair of the attachment portions, and to protect the unit from the outside. From a state where the protective cover is removed, insertion nails arranged at a first edge of the protective cover are respectively inserted into insertion openings arranged at the mounting shelf to support the first edge of the protective cover.
