A bus bar assemble type electric current sensor includes a sensing module that has a resin molding and a sensing element provided in the resin molding, and a bus bar module that has a casing and a bus bar accommodated in the casing and disposed in the vicinity of the sensing element. A temporarily-fixing portion that temporarily fixes the sensing module and the bus bar module separably is provided on at least one of the sensing module and the bus bar module. A fully-fixing portion that integrally fixes the sensing module and the bus bar module with each other is provided on each of the sensing module and the bus bar module.

Bus bar assemble type electric current sensor

A power converterincludes: a power modulethat converts direct-current electric power to three-phase alternating-current electrical power and outputs the three-phase alternating-current electrical power from three-phase terminals; an output bus barthat has motor terminalsand a plurality of power module terminalsthat are connected to the power module; a bus bar holderholding the output bus bar; and a casethat has a through holethrough which the output bus barpenetrates and that accommodates the power module, the output bus bar, and the bus bar holder. The three-phase terminals are arranged side-by-side on the power module. The plurality of power module terminalsare respectively formed on the output bus barso as to correspond to the three-phase terminals, and the plurality of power module terminalsare positioned on the three-phase terminals when the output bus barand the power moduleare accommodated in the case

Power converter capable of converting direct-current electric power or three-phase alternating-current power

This capacitor structure is provided with a capacitor body in which a plurality of wound-type capacitors are housed in a housing, and which is fixed to a fixing object via a fastening tool (a cylindrical member and a fixing bolt). The capacitor structure is configured such that the capacitor body is fixed to the fixing object by inserting the fastening tool into at least one of a gap formed between the outer peripheral surfaces of the wound-type capacitors or gaps formed between the outer peripheral surfaces of the wound-type capacitors and the inner wall of the housing, in a state in which the wound-type capacitors are installed side by side on the floor of the housing.
