A power converter includes a cabinet and an electric device accommodated in the cabinet. The cabinet includes a housing, a door, a support member, and a rotation mechanism. The door is rotatably supported around a first axis with respect to the housing. The support member is interposed between the housing and the door to support the door in the housing. The rotation mechanism rotates the door with respect to the housing around a second axis along a direction orthogonal to a plane direction of an opening of the housing.

A power converter includes a power conversion module including a heat generation device, a cooling medium path through which a cooling medium for cooling the heat generation device flows, and a cooling medium collection unit disposed facing the power conversion module and collecting the cooling medium that has cooled the heat generation device. The power conversion module includes a first heat conductive member in which a first flow path forming a part of a cooling medium path is provided. The cooling medium path includes a first connecting pipe connecting a first flow path provided in the first heat conductive member with the cooling medium collection unit. The power converter further includes a first support tool provided in at least one of the cooling medium collection unit and the power conversion module and supporting the first connecting pipe.

An apparatus, such as a power routing apparatus, includes an enclosure having first and second compartments having respective first and second opposing walls. A cooling structure is disposed between the first and second compartments and has a coolant passage defined therein configured to support a coolant flow in a direction parallel to the first and second opposing walls. First and second semiconductor switches (e.g., static switches) are disposed on the first and second walls on opposite sides of the coolant passage and are configured to be cooled by the coolant flow.

This invention discloses a rackless modular power electronic system that optimizes thermal management, modularity, manufacturability, transportation, and installation. Such a power electronic converter system consists of one or more modular power electronic converters mounted one-on-top-of-another and/or one-next-to-another through mounting units, such as screws, nuts and bolts. Each modular power electronic converter is built with a case with heat-dissipating fins on the exterior surface and with vertical and horizontal mounting mechanisms, such as holes, bolts, nuts and screws, which are aligned vertically and horizontally, respectively, for easy mounting. One or more electric fans can be mounted to the system to enhance heat dissipation. Possible applications include any field that adopts power electronic converters, e.g., in wind power, solar power, storage systems, home appliances, IT equipment, motor drives, electric vehicles, more-electric aircraft, and all-electric ships.

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 power supply structure comprises a housing, a socket and a fan. The housing has a main housing, a terminal housing and a front panel, wherein the terminal housing connected with the main housing. The fan and the terminal housing disposed on one end of the main housing, and the fan attached to the front panel. The socket arranged in parallel with the fan and connected to the terminal housing.

The present application provides a power supply cabinet, comprising a first power supply region and a second power supply region including at least one slot for receiving a first power supply module and a second power supply module respectively, a mode switching unit for outputting a mode signal to the first power supply module and the second power supply module, and a position setting unit for outputting a position signal to the first power supply module and the second power supply module. Input sides of the first power supply module and the second power supply mode are electrically connected to a first power supply and a second power supply. The power supply cabinet selectively operates in a first power supply mode (e.g. N+N mode) or a second power supply mode (e.g. N+1 mode) depending on the mode signal or types of the power supplies.

A first projection and a second projection are disposed around an opening in a housing. A first fitting hole into which the first projection is to be fitted and a second fitting hole into which the second projection is to be fitted are formed around a central hole in a packing. The first projection and the second projection are respectively fitted into the first fitting hole and the second fitting hole, whereby the packing is attached to the housing. A cover to cover the opening and on an area around the opening is attached to the housing by means of a fastening member mated with the second projection with the packing placed between the cover and the housing.

A power conversion device includes: a housing including a floor, a ceiling, a front face; an input circuit part; a power conversion unit; a reactor; an output circuit; and an output terminal. These elements are arranged in a planar direction of the front face so as not to overlap each other. The input circuit part is provided above the floor, the output circuit part is provided below the ceiling and above the input circuit part, and the power conversion unit is provided above the input circuit part between the input circuit part and the output circuit part. The reactor is provided beside or above the power conversion unit between the input circuit part and the output circuit part. The input circuit part, the power conversion unit, the reactor, the output circuit part, and the output terminal are connected in series in this order through metal bus bars.

A control device for a railway vehicle includes a housing and a cover covering an opening. The cover is provided with a lock and a restricting member. The restricting member is located in one of a lock permitting position for permitting locking of the cover and a lock restricting position for restricting locking of the cover. The control device further includes an urging member that urges the restricting member to the lock restricting position. When the cover closes the opening, a pushing member pushes the restricting member to the lock permitting position, resulting in permission of locking of the cover.
