A power supply assembly includes a power supply unit disposed within a housing and an adjustable plate module movably disposed on a floor thereof. The adjustable plate module includes a plate, a shaft, a stopper panel, and a compressible device. The plate has two planar surfaces positioned at different heights with respect to the floor. The shaft is fixedly coupled to and extends outwardly from the plate. The shaft is configured to move between a first position and a second position to transition a connector between the planar surfaces. The stopper panel is disposed adjacent to a distal end of the shaft and has an opening therein for accommodating the shaft. The compressible device is disposed around the shaft such that a displacement of the plate causes the compressible device to compress against the stopper panel and facilitate movement of the shaft from the first position to the second position.

A method for installing a heavy and bulky switching module, in particular a static transfer switch, in an electrical cabinet, by way of an installation kit to make the switching module easily removable and interchangeable, regardless of its size and weight. The electrical cabinet is equipped with the installation kit including at least two support rails, extendable between an extended position outside, and a retracted position inside, the electrical cabinet, and forming two parallel rolling paths. The switching module is equipped with rollers in two parallel rows, arranged to circulate on the rolling paths to enable movement of the switching module relative to the electrical cabinet by pushing and pulling with minimal effort. A raised transport pallet is also used to facilitate handling of the switching module outside of the electrical cabinet by a simple industrial truck, without resorting to a lifting device.

A vehicle-mounted inverter skid wherein the bottom plate of a box body (100) is equipped with a plurality of support beams (105), and the height of the support beams (105) is less than the height of a support frame (104), such that the box body (100) is a sunken structure relative to the support frame (104), and the height dimension of the box body (100) is reduced by it being sunken in the direction of the support frame (104); a wire feed-in assembly of a wire feed-in unit (200) comprises a wire feed-in terminal (202) and a wire feed-in bracket (203); the wire feed-in bracket (203) is shaped like the Chinese character for a door, its top plate is provided with an wire feed-in hole (2031), and the wire feed-in terminal (202) is vertically insertedly disposed in the wire feed-in hole (2031) for fixing; the bottom plate of the box body (100) has a wire feed-in port (204) corresponding to the location of the wire feed-in hole (2031), such that the wire feed-in terminal (202) is arranged vertically, reducing the horizontal footprint of the wire feed-in assembly; combined with a magnetic excitation assembly (205) of the wire feed-in unit (200) being separated and arranged in the vacant space on the side of a transformer unit (300), the length and width of the inverter sled are reduced, thus reducing the overall volume of the inverter skid, solving the technical problem of the large size of existing inverter sleds and making it more suitable for vehicle-mounted use.

A subrack including a frame defining a subrack space and adapted to receive a device module to an operative position, the frame comprising four side walls and an end wall. The subrack comprises a coupling system adapted for coupling the subrack to four other subracks in order to form a subrack matrix, the coupling system comprising at least one wall recess on an inner surface of each of the side walls, and at least one primary screw hole in each of the side walls such that the at least one primary screw hole is located in the at least one wall recess.

A capacitor unit includes: a base portion with a mount surface, and a locking member. The locking member includes a shaft portion to be inserted in a hole provided in the mount surface and a head portion. A first guide member and a second guide member guide along an anteroposterior direction, a first end and a second end of the base portion in a lateral direction, respectively. The hole is located between the capacitor and the first end in the lateral direction, and arranged at a position more distant from an opening than the first guide member in the anteroposterior direction. At a first engagement position, the locking member abuts on the first guide member. At a second engagement position, abutment of the locking member on the first guide member is canceled.

A rack device having a cabinet and power modules stacked in the cabinet is provided. The power module has a frame, an insulative plate, an insulative cover and transformers. The insulative plate is arranged in the frame. The insulative cover is arranged in the frame and disposed spacedly from and parallel with the insulative plate. Each transformer arranged in the frame has a high-voltage set and a low-voltage set electrically connected with each other. The low-voltage sets are arranged on one surface of the insulative plate and do not protrude from the frame, and the high-voltage sets are arranged on another surface of the insulative plate and between the insulative plate and the insulative cover. The frame of each power module is connected with the frame of adjacent power module, and the frame of at least one of the power modules is connected to the cabinet.

A power distribution assembly comprising a chassis having at least one wall, a deformable material layer positioned on the at least one wall of the chassis and configured to deform in response to a triggering even. The power distribution assembly further comprising a conductive sense layer positioned on the deformable material layer opposite the at least one wall of the chassis.

A ground power unit provides electrical energy for aircraft and a method maintains and operates the ground power unit. The ground power unit includes a base frame, a cable system formed in the base frame, at least one rectifier module for converting an input alternating voltage applied to a rectifier module input side into an intermediate direct voltage output at a rectifier module output side, wherein the rectifier module output side is coupled to an intermediate circuit conductor and at least one inverter module for converting the intermediate direct voltage applied to an inverter module input side into an output alternating current output at an inverter module output side, wherein the inverter module input side is coupled to an intermediate circuit conductor.
