The utility model relates to the technical field of batteries, and discloses a battery pack. The battery pack comprises a box body and a battery pack arranged in the box body, and the battery pack comprises a plurality of battery monomers arranged along a first direction; the battery pack comprises a busbar and an acquisition piece, the busbar is connected between poles of adjacent battery monomers, the busbar is provided with a body part and a convex part, and the body part is provided with a welding area; the collecting part is arranged on the upper surface of the body part, the upper surface of the protruding part is higher than the upper surface of the collecting part, the collecting part at least shields the welding area, and at least part of the busbar is higher than the top surface of the collecting part. The collecting piece of the battery pack at least shields the welding area, the upper surface of the protruding part is higher than the upper surface of the collecting piece, damage to the collecting piece can be effectively reduced, and meanwhile connection of the welding positions of the busbar and the pole is more reliable.

This utility model relates to the field of automatic system control technology for heat exchange stations, specifically a modular control cabinet for an automatic system in a heat exchange station. It includes a control cabinet body with a door installed on its surface. A base is placed on the lower surface of the control cabinet body, and a replacement device is provided on the lower surface of the control cabinet body. The replacement device includes an anti-slip rod, which is fixedly connected to the lower surface of the control cabinet body. A storage hole is provided on the upper surface of the base, and the anti-slip rod is inserted into the storage hole. A placement plate is fixedly connected to the surface of the control cabinet body and rests on the surface of the base. A stop bar is placed on the surface of the placement plate, and a support assembly is provided on the surface of the base. This utility model, by providing a replacement device, effectively facilitates the replacement of a rusted control cabinet body by workers, avoiding the need for workers to spend a significant amount of time replacing the entire control cabinet, thereby reducing resource waste.

The utility model provides a circuit board and a guide rail ammeter, and belongs to the technical field of electrical equipment. The circuit board is applied to the guide rail ammeter. The guide rail ammeter comprises a base. The circuit board comprises a body and a wire arrangement structure. The body is arranged on the base and comprises a first face and a second face which are opposite in position, the first face is opposite to the bottom wall of the base, the second face faces the bottom wall of the base, and a welding structure is arranged on the first face. The wire arrangement structure is arranged on the body and on the side, close to the edge of the body, of the welding structure, the wire arrangement structure can communicate with the first face and the second face, and the wire arrangement structure can provide a penetrating space for the voltage wire, so that one end of the voltage wire is connected to the base, and the other end of the voltage wire is connected to the welding structure. According to the guide rail electric meter, the voltage line penetrates through the body and is connected with the first surface, so that the voltage line can be straightened, the possibility that the voltage line is stacked between the second surface and the base is reduced, the probability of short circuit caused by damage of the voltage line can be reduced, and the use reliability of the guide rail electric meter is improved.
