This utility model relates to the field of prefabricated substation technology, specifically to a heat dissipation structure for a photovoltaic or wind-powered prefabricated substation. It includes a prefabricated box with a top plate. The box is divided into a transformer compartment, a high-voltage compartment, and a low-voltage compartment. The low-voltage and high-voltage compartments are separated from the transformer compartment by partitions. The low-voltage compartment contains a low-voltage cabinet. Multiple elongated ventilation slots are spaced parallel to each other along the height of the low-voltage cabinet on the upper and lower parts of the partition. Tin plates are installed at the connection holes between the low-voltage cabinet and the transformer copper busbars on the partition. A mesh door separates the front of the transformer compartment from the box door. The beneficial effects of this utility model are: the heat dissipation structure for a photovoltaic or wind-powered prefabricated substation achieves air circulation through the partition with ventilation slots and the mesh door. It also features a box door sealing plate with louvers and ventilation holes, and includes an air conditioner and a fan, providing effective heat dissipation for the box, thereby reducing line loss and copper loss and maintaining power supply efficiency.

This application discloses an adaptive configuration method, apparatus, device, and storage medium for JP cabinets, belonging to the field of JP cabinet load configuration technology. This application obtains a main node graph characterizing the real-time operating status of a distribution transformer area and a secondary node graph characterizing the future operating trend and adjustability of the distribution transformer area; it performs cross-graph feature fusion on the main node graph and the secondary node graph, and outputs adaptive configuration instructions for the nodes where each JP cabinet in the distribution transformer area is located based on the cross-graph feature fusion result; it sends the adaptive configuration instructions to the corresponding JP cabinets for execution and collects the operating status data after execution; based on the operating status data, it synchronously updates the main node graph and the secondary node graph, and continuously optimizes the configuration parameters of each JP cabinet based on the updated main node graph and secondary node graph, thereby achieving the effect of accurately allocating the load of the JP cabinets.

This utility model relates to the field of battery testing equipment technology, specifically to a pull-out needle box structure and a battery testing needle bed. The pull-out needle box structure includes a box body forming an internal chamber and a fixing frame for fixing the box body. A power module is integrated and installed in the chamber of the box body for powering the probes and for testing sampling. At least one cooling fan is provided in the chamber of the box body for dissipating heat from the power module. At least one probe interface is arranged on the bottom surface of the box body. The probe interface is electrically connected to the power module. The box body is detachably mounted on the fixing frame via a pull-out structure. The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pull-out needle box structure and a battery testing needle bed, solving the problems of numerous cables, high line loss, inconvenient maintenance, and poor heat dissipation in the prior art.
