[0018] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The inventors found that the existing cabinets of the same type are large in size, or the electrical devices are not fully installed. The input and output side AC and DC circuit breakers cannot be installed in the cabinet. Instead, they are installed in an external electrical cabinet and then connected through copper bars. At least two cabinets will be used, and a large number of copper bars are required for electrical connection, which is costly. In addition, most of the power supply electrical equipment in the existing cabinets are not whole U products that are suitable for standard cabinets. The cabinets are designed and installed according to the non-standard structure of the equipment. The power input and output are connected by wiring, which has low production efficiency and maintenance efficiency. The maintenance time for a single device is about 0.5 hours.

[0021] Among them, full U products refer to electrical equipment or modules designed according to the U (Unit) height specifications of standard cabinets. Here, "U" is the standard height unit of server cabinets, 1U = 1.75 inches. The core feature of full U products is standardized size, which can seamlessly adapt to the installation structure of standard cabinets without customized modification.

The front reinforcement beams 114 and the rear reinforcement beams 115 of the columns provide auxiliary support for the equipment rear middle column 106 and the equipment middle front column 112 to form the installation space of the two lower rows of standard cabinets and the upper electrical equipment installation space. The four corners of the lower part of the cabinet are welded with four corner supports 109, and the center of the side is welded with four middle supports 110. The cabinet can be moved by a forklift.

[0027] It can be understood that the cabinet style is double-row double-door. In order to facilitate equipment installation and electrical operation, the cabinet is designed to distribute space according to functional components, effectively divide the area, and improve the utilization rate of the internal space of the cabinet. The equipment is installed in the lower part, and the circuit breaker and input and output ports are arranged in the upper space. In order to effectively utilize the space, the lower part of the rack is divided into two rows of standard cabinet space by the front and rear equipment center columns. The lower equipment space can install enough power equipment, and the power equipment is located low, which is convenient for maintenance and replacement. The electrical installation space above is completely open, which is enough to install input and output circuit breakers and copper bars.

[0030] The auxiliary electrical installation bracket 51 is installed on the rear reinforcing crossbeam 115 of the column, and the two electrical installation rails thereon can be used to install devices such as circuit breakers and fuses. The triangular mounting bracket 521 and the U-shaped mounting plate 522 are installed in combination on the equipment column on the left side for installing the output DC circuit breaker. Eight electrical installation brackets 531 are installed on the front, rear and middle equipment columns, and four electrical installation plates 532 are installed on the electrical installation brackets 531, which are used to install the lower-level shunt copper busbar and arrange the power supply cables of the upper and lower power equipment.

The AC circuit breaker supplies power to the four busbars through copper busbars and cables respectively. Each group of busbars supplies power to the equipment circuit breaker in front. The equipment circuit breaker is connected to the input plug-in terminal of the power supply device through the busbar and the side of the equipment installation rail. The layout of electrical, copper busbars and cables makes full use of the cabinet space, reduces the use of copper busbars and copper wires, and reduces equipment costs.

[0034] In addition, the DC busbar is arranged near the output terminal, and the double-layer copper busbar fully reduces weight and space occupancy. After the two sets of busbars converge at the top, they are connected to the DC circuit breaker located behind the electrical installation space. One set is connected to two fuses, and the wiring holes on the circuit breaker can be connected to the terminals to output the converted electrical energy. The amount of copper busbars used is effectively reduced, reducing equipment costs.

The equipment is supported by the guide rails in the mounting bracket group 5 installed on both sides of the cabinet. After being inserted into the cabinet, it can be connected to the plug-in terminals installed on the terminal mounting strip at the back of the cabinet to complete the input and output electrical connection. The guide pins are installed at the back of the power supply equipment housing. Before the male and female sockets of the plug-in terminals come into contact, they can cooperate with the guide holes on the terminal mounting strip to correct the equipment orientation and facilitate the terminal insertion. The handle on the front of the equipment and the mounting hole on the front of the cabinet are connected by 4 M6 screws.
