A power conversion apparatus is provided to prevent the arc flash generated in a board from flowing out to a operation surface for operating the board, and also to relieve the pressure inside the board to the outside from the flapper section provided on the ceiling. The power conversion apparatus that has taken measures against an arc flash composed of a power converter and a board accommodating the power converter is provided. A BUS which constitutes the power converter has the first processing that makes it hard to fly the flash in a place where arc flash is not desired to occur. A door is placed on the front board that can be opened and closed by the operator. The board has an explosion-proof shutter part to prevent the arc flash from being released to the outside by the pressure inside the board, and has a flapper section for releasing the pressure inside the board to the outside from the ceiling of the board unit, when the arc flash occurs.

A power conversion device and an integrated machine are provided, The power conversion device includes a housing and a power converter. The power converter is arranged in the housing, and two ends, opposite to each other, of the power converter are respectively provided with a direct current wiring area and an alternate current wiring area. Two ends of the housing corresponding to the direct current wiring area and the alternate current wiring area each is provided with a movable door being capable of being opened and closed.

The invention discloses a power module and a power conversion device. The power module includes a primary converting unit including a first active device unit; a secondary converting unit including a second active device unit; a transformer including a primary unit connected to the primary converting unit and a secondary unit connected to the secondary converting unit; a first heat dissipating unit on which the primary unit and the first active device unit are disposed; a second heat dissipating unit on which the secondary unit and the second active device unit are disposed; and an insulating plate including an insulating plate body and a semi-conducting layer disposed on a surface of the insulating plate body.

In a method of checking normal input power and load of a programmable AC power distributor in its power-on state, indicator lights are installed in an output ON button and an output OFF button. During power ON, a master switch is switched to an ON position to detect the input power and obtain a detection result through a change of the indicator light in the output OFF button, and then the output ON button is pressed to check the power-on state of the load and obtain a detection result by outputting the change of the indicator light of the button. Therefore, users can instantly know whether the input power and load are in a normal state during the operation of turning on the power distributor, and this method makes the operation of the power distributor safer and more convenient, and ensures a high quality of power supply.

A control cabinet for at least one electrical drive controller includes a control cabinet housing a first cabinet compartment formed in the control cabinet housing and having at least one inlet opening for fresh air, at least one first transfer opening and a fresh air duct flow-connecting the inlet opening to the first transfer opening. A second cabinet compartment is formed in the control cabinet housing and has at least one outlet opening for exhaust air, at least one second transfer opening, and an exhaust air duct flow-connecting the outlet opening to the second transfer opening. A third cabinet compartment is formed in the control cabinet housing and is sealed off in terms of flow from the first cabinet compartment, the second cabinet compartment, and the environment outside the control cabinet. A partition delimits the third cabinet compartment in terms of flow from the first cabinet compartment and the second cabinet compartment, and has the at least one first transfer opening and the at least one second transfer opening. The third cabinet compartment is in the form of a rack with at least one drawer, wherein each drawer is designed to receive an insertable control device.

A module panel and method include an exterior housing, at least one heat sink disposed in the housing, a power delivery circuit disposed in the housing and coupled to one side of the at least one heat sink, and a controller circuit disposed in the housing and coupled to an opposite side of the at least one heat sink. The power delivery circuit operates using one or more different voltages than the controller circuit.

Locking members disposed on a casing of an underfloor device for railway vehicles engage hanging tools disposed on the vehicle, whereby the underfloor device for railway vehicles is attached to the vehicle. The locking member is a hollow locking member that includes a locking part to contact and engage a vertically upper face of part of the hanging tool, a mount part attached to the casing, and a connection part connecting the locking part and the mount part. The locking part is disposed at a position spaced apart from the casing horizontally and vertically upward. The locking part contacts and engages the vertically upper face of part of the hanging tool inserted into a space surrounded by the locking part, the mount part, and the connection part.
