[0025] For details, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of the device provided in an embodiment of this application. Figure 2 This is a partial structural diagram of the first mounting plate and its connection points provided in an embodiment of this application. Figure 3 This is a partial structural diagram of the integrated component provided in an embodiment of this application. Figure 4 This is a partial structural diagram of the buckle plate provided in an embodiment of this application. The power distribution cabinet 100 used in the photovoltaic-storage power generation training and maintenance system includes a cabinet 110, which naturally includes a front door, a rear door, a top plate, etc. The main body of the cabinet 110 can be made of high-strength material to give it good mechanical strength and protective performance. A first mounting plate 120 is provided on the inner bottom wall of the cabinet, and the first mounting plate 120 is set tightly against the cabinet 110. The first mounting plate 120 and the cabinet 110 can be integrally formed. A heat dissipation chamber 130 is provided at the bottom of the inner cavity of the enclosure. A horizontal partition 131 is provided in the middle of the heat dissipation chamber 130, which divides the heat dissipation chamber 130 from top to bottom into a ventilation chamber 132 and a receiving chamber 133. A load device 160 is provided in the receiving chamber 133. The load device 160 can be set with a load of 100kW to 5000kW. The load device 160 will overheat during operation. A fan 131a is provided at the horizontal partition 131. An air inlet 132a is opened on the outer wall of the ventilation chamber 132, and an air outlet is opened on the outer wall of the receiving chamber 133. The fan 131a can be turned on during operation. The fan 131a drives the cold air outside the box into the ventilation chamber 132 through the air inlet 132a and then into the receiving chamber 133. The hot air in the receiving chamber 133 will be discharged through the air outlet 133a. The first mounting plate 120 is arranged from top to bottom as a control area 121 and a power supply area 122. The control area 121 is arranged from top to bottom as a plurality of integrated components 140. The integrated components 140 are used to install various electrical components such as circuit breakers, meters 150, relays 170 and shunts. Integrated component 140 includes an integrated plate 142 connected to a first mounting plate 120 via a hinge 141. The other end of the integrated plate 142 is connected to the first mounting plate 120 via a resilient latch 143. A meter 150, a relay 170, and a shunt are detachably mounted on multiple integrated plates 142. During use, one end of the integrated plate 142 can be fixed using the resilient latch 143. When it is necessary to install or adjust the electrical components on the integrated plate 142, the end of the integrated plate 142 with the resilient latch 143 is removed. At this time, the integrated plate 142 can rotate around the hinge 141 to a suitable angle (e.g., ...). Figure 2This facilitates the installation and removal of electrical components on the top of the integrated board 142. After the electrical components are installed, the integrated board 142 is rotated around the hinge 141 again to fix its free end at the elastic buckle 143. Two rows of buckle holes 124 are symmetrically arranged on the first mounting plate 120 at the power supply area 122. Buckle plates 125 are detachably installed at the buckle holes 124 from top to bottom. The buckle plates 125 can be easily fastened through the buckle holes 124 on the first mounting plate 120. The inverter 190 and lithium battery 180 are detachably fixed at the buckle plate 125. When it is necessary to install or replace components such as the inverter 190 and lithium battery 180, the buckle plate 125 can be removed along the buckle holes 124 and moved to the outside of the enclosure 110. At this time, the installation process will no longer be limited by the narrow space of the enclosure 110, and the installation action can be completed conveniently and quickly.

[0026] As can be seen from the above, in this embodiment, the power distribution cabinet has a compact layout, with each functional module cooperating with each other, greatly reducing the cabinet's volume and optimizing space utilization. This makes the entire system more compact, facilitating installation in training sites and providing convenience for later maintenance. The power distribution cabinet has good scalability. The cabinet interior, through the integrated plate 142 and the snap-fit ​​holes 124 on the first mounting plate 120, provides sufficient space and interfaces, allowing for easy addition of new equipment and modules according to training needs and technological advancements. For example, a sensor module can be added to monitor environmental parameters such as temperature and humidity inside the cabinet in real time, ensuring the normal operation of the equipment. In this application, the heat dissipation cavity 130, fan 131a, and other components work together to ensure that the fan 131a can drive airflow through the heat dissipation cavity 130 during operation, thereby removing the heat dissipated by the load equipment 160 during operation.

[0027] In some embodiments, the snap-fit ​​plate 125 has a triangular cross-section formed by its bottom side gradually sloping downwards from the end away from the first mounting plate 120 to the end near the mounting plate. Two handle components 125a are symmetrically arranged on the top side of the snap-fit ​​plate 125. In this embodiment, by making the bottom side of the mounting plate slope to form a triangular bevel, the mounting plate can provide stable support. By providing the handle components 125a, operators can use both hands to hold the handle components 125a to complete the handling and installation operations of the snap-fit ​​plate 125.

[0028] In some embodiments, the elastic buckle 143 includes a movable block 143a. A limiting ring 143b is provided on the side of the movable block 143a away from the integrated plate 142. The limiting ring 143b is fixed on the first mounting plate 120. A limiting rod 143c is connected to the movable block 143a. The limiting rod 143c is disposed through the limiting ring 143b. A compression spring 143d is sleeved on the limiting rod 143c between the limiting ring 143b and the movable block 143a. The side of the movable block 143a near the integrated plate 142 forms an inclined surface. In this embodiment of the application, a specific setting of the elastic buckle 143 is provided. When it is necessary to fix the integrated plate 142, the integrated plate 142 is rotated so that the free end of the integrated plate 142 contacts the inclined surface of the moving block 143a. After pressing the integrated plate 142, the integrated plate 142 pushes the moving block 143a backward through the inclined surface. The moving block 143a compresses the compression spring 143d and moves backward until the integrated plate 142 completely slides over the inclined surface and enters the back of the moving block 143a. At this time, the moving block 143a is reset under the action of the compression spring 143d, and the free end of the integrated plate 142 is clamped between the first mounting plate 120 and the moving block 143a.

[0029] In some embodiments, a groove 126 is provided on the first mounting plate 120, and two slide rails 143e extending into the groove 126 are provided on the side of the moving block 143a near the first mounting plate 120. An anti-slip protrusion 143f is provided on the side of the moving block 143a away from the first mounting plate 120. In this embodiment, the groove 126 and slide rails 143e can further ensure the stability of the moving block 143a during horizontal movement and avoid deviation. When it is necessary to remove the restriction on the free end of the integrated plate 142, the operator can push the moving block 143a backward by pressing the anti-slip protrusion 143f on the moving block 143a and compressing the compression spring 143d. The moving block 143a moves away from the free end of the integrated plate 142, at which time the integrated plate 142 can be rotated away from the elastic buckle 143.

[0030] In some embodiments, a slot 141a is provided at the hinge 141, and one end of the integrated plate 142 is detachably connected to the hinge 141 through the slot 141a. In this embodiment, with the above-described configuration, when the elastic buckle 143 releases the restriction on the integrated plate 142, the integrated plate 142 can be rotated to a certain angle through the hinge 141 and then pulled out from the slot 141a. At this time, the integrated plate 142 can be moved to the outside of the housing 110, and is no longer limited by the internal space of the housing 110, enabling a faster and more convenient completion of the installation operation of various components on the integrated plate 142.

[0031] In some embodiments, a vertical plate 125b is vertically fixed to the top of the snap-fit ​​plate 125, and multiple heat sinks 125c are horizontally arranged on both sides of the vertical plate 125b. The inverter 190 and the lithium battery 180 are respectively fixed to the heat sinks 125c on both sides of the vertical plate 125b. In this embodiment, through the above arrangement, the inverter 190 and the lithium battery 180 are respectively arranged on both sides of the vertical plate 125b, which effectively saves space inside the distribution cabinet, making the internal structure of the device more compact. On the other hand, the heat sinks 125c increase the contact area with air, which helps the inverter 190 and the lithium battery 180 to dissipate heat quickly.
