The invention relates to an extension kit for an IT equipment cabinet having two vertical profiles, two transverse profiles and four depth profiles. The two vertical profiles and the two transverse profiles form a rectangular frame, wherein each depth profile is fastened to the frame with one of its ends. In addition, two adapter profiles are provided, which are arranged parallel to the vertical profiles on the other ends of the depth profiles. These are designed to be fastened to an IT equipment cabinet to extend a depth of the cabinet without affecting its height or width.

The present invention relates to a module replacement device of a high voltage direct current transmission system. In the present invention, a replacement base (40) is provided in a structure (1) by using a support member (70) such that a sub-module (30) movably provided at a fixing base (10) of the structure (1) can be replaced by being withdrawn outside of the structure (1). A rear end of a base plate (42) of the replacement base (40) is hooked to an insulation support part (9) of the structure (1), and a front end of the replacement base (40) is supported by the support member (70) hooked to one side of the structure (1). The support member (70) is provided with a turn buckle (74) so as to adjust the replacement base (40) such that the replacement base is horizontally provided thereto. The rear end of the replacement base (40) is provided with a rail connection guide (62) for matching a fixing rail (16) of the fixing base (10) provided in the structure (1) with a guide rail (51) of the replacement base (40). The rail connection guide (62) has a rail slot (64) so as to guide the fixing rail (16) to the guide rail (51) side. According to the present invention as above, the replacement base (40) can easily and firmly be provided in the structure (1) such that the module (30) can be replaced in an easy and safe manner.

An apparatus includes an enclosure comprising first and second abutting compartment and at least one cable passing between the first and second compartments through a sealing multi-cable transit mounted in a wall shared by the first and second compartments. The first compartment may contain arc-generating equipment and the second compartment may contain equipment vulnerable to arc damage. The first compartment may include a medium-voltage cubicle and the second compartment may include a low-voltage control cubicle.

The present disclosure relates to a power supply system (1) including a main unit (10) including a protective main housing (11) and a distribution circuit (20) disposed in the protective main housing (11); a first module unit (30a) including a first protective module housing (31a) and a first electric module (40a) disposed in the first protective module housing (31a). The system also includes a passive cooling system (70) for cooling of the main unit (10) and the first module unit (30a). A first protective connection system (CS1) and a second protective connection system (CS2) is also a part of the system, wherein the first protective connection system (CS1) is configured to provide a releasable electrical and mechanical connection between the main unit (10) and the first module unit (30a). The passive cooling system (70) includes cooling fins (71) disposed on an outer surface of the first protective module housing (31a).

An apparatus includes a switch cabinet and a device housing. The device housing is adapted to accommodate a component of a device and the switch cabinet is adapted to accommodate electrical equipment for the device. The switch cabinet is operable to be moved between an open position and a closed position relative to the device housing. When in the closed position a wall of the switch cabinet closes off an opening in the device housing, and when in the open position the wall of the switch cabinet is removed from the opening in the device housing so as to expose that opening.

A connector for combining cabinets includes a flexible connector which is deformable and is configured to communicate inner cavities of a first cabinet machine and a second cabinet machine. The flexible connector includes a hollow cavity for an electrical connector to pass through, and the hollow cavity forms a first open end and a second open end at two ends of the flexible connector. The first open end is sealingly connected to a side plate of the first cabinet machine, the second open end is sealingly connected to a side plate of the second cabinet machine, and the first cabinet machine and the second cabinet machine are two adjacent cabinet machines. The structure of the connector for combining cabinets is simple and the mounting is convenient, and the flexible connector can automatically adapt to the mounting position through its own deformation so as to meet the normal mounting requirements.
