Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, and in particular relates to a horizontal power supply case. Background Art

[0002] As an important part of the power supply system, the power supply chassis is responsible for protecting the internal electronic components. The existing power supply chassis usually installs the transformer and electrical components inside the chassis. Although this design is compact, it has several problems: first, the thermal management problem. The heat generated by the transformer during operation may affect the performance and life of other electrical components; second, the maintenance is inconvenient. All components are installed inside the chassis, making the maintenance and replacement of electrical components complicated and time-consuming; finally, the safety issue. The high-voltage components are too close to the electrical components that the user can touch, increasing the risk of electric shock. In addition, the structural design of the existing power supply chassis is often relatively simple, lacking effective heat dissipation measures and modular design, which makes the chassis prone to overheating under high load and also limits the scalability and upgrade capabilities of the power supply system.

[0038] As attached Figure 1-5 As shown, in an illustrative embodiment of a horizontal power supply chassis of the utility model, the power supply chassis can be used to independently power electronic equipment, or cooperate with other power supply chassis to power electronic equipment. The power supply chassis includes a box body 1, a transformer, a device mounting plate 2 and electrical components.

[0039] The box body 1 is assembled from a bottom plate 11 , a top plate 12 and three side plates 13 . The side of the box body 1 without the side plate 13 forms an opening, and the bottom plate 11 bends and extends toward the opening side to completely or semi-close the box body 1 .

[0040] The transformer is installed inside the box 1;

[0041] The device mounting plate 2 is arranged on the side wall of the box body 1 , and the electrical devices are mounted on the outside of the box body 1 through the device mounting plate 2 . In this embodiment, the electrical devices include but are not limited to the contactor 4 , the miniature circuit breaker 5 and the terminal block 3 .

[0042] This technical solution can reduce mutual electromagnetic interference and improve the electromagnetic compatibility of the power supply chassis by separating the transformer and the electrical components.

Installing it inside the chassis and the electrical components outside the chassis can effectively isolate the heat source, reduce mutual heat influence, and optimize the thermal management of the entire power supply chassis. At the same time, installing the electrical components outside the chassis is also convenient for users to operate. Maintenance personnel do not need to open the entire chassis when performing maintenance or replacing electrical components, saving time and reducing maintenance costs.

[0043] In order to reduce the material cost of the box body 1 and the overall weight of the power supply chassis, in some embodiments of the present invention, such as the attached Figure 1As shown, the device mounting plate 2 is fixed to the open side of the box body 1 without the side plate 13 , and as a part of the outer wall of the box body 1 , it closes the box body 1 together with the bent and extended end of the bottom plate 11 .

Electrical components such as the terminal block 3 and the output line of the transformer are fixedly mounted on the first mounting plate 21 .

[0046] The second mounting plate 22 is protruding from the outer wall of the box body 1, and is pressed on the first mounting plate 21 and the upper part of the bent extension end of the bottom plate 11. Connectors are vertically arranged at both ends of the length direction, and are fixedly connected to the first mounting plate 21 and the bottom plate 11 through the connectors. Electrical components such as the contactor 4 and the miniature circuit breaker 5 are fixedly mounted on the second mounting plate 22. One side of the second mounting plate 22 in the length direction is the power inlet terminal, and the other side is the power outlet terminal.

The setting of the internal frame 7 also helps to disperse the load and improve the structural strength of the chassis.

[0052] In order to enhance the strength of the box body 1 , in some embodiments of the present invention, the top plate 12 and the three side plates 13 are integrally bent and formed.

[0053] In order to enhance the stability of the internal frame 7, in some embodiments of the present invention, as shown in the attached Figure 5 As shown, an inclined beam 73 is provided between at least two support rods 72 and the rectangular bottom frame 71 , and two ends of the inclined beam 73 are fixedly connected to the support rods 72 and the rectangular bottom frame 71 by screws.
