Utility Model Content

[0003] Design purpose: In order to avoid the shortcomings of the background technology, a new energy substation with a split box structure is designed, which can not only prevent the damage to the heat sink assembly caused by bumps and vibrations during transportation, but also protect the fuel tank during transportation. At the same time, the pull rod can be easily disassembled and installed, and the tensioning force of the pull rod can be adjusted.

[0004] Design plan: To achieve the above design objectives.

[0005] 1. The heat dissipation device is to be connected with a bridge sprocket wheel, the second end of which is connected to the hubcaps groove, the bridge sprocket wheel, the second end of which is connected to the hub by a toothed connection, and the toothed connection of the bridge is connected with the toothed connection of the bridge. The purpose of this design is that: a row of heat sink groups are respectively provided on both sides of the oil tank in the oil-immersed transformer, and a heat sink oil pipe is provided at the bottom of each heat sink group. The lower parts of the heat sink oil pipes on the same side are fixedly connected to the upper part of the same cantilever beam, and gaps are left between adjacent heat sink groups in the same row of heat sink groups. A plurality of through holes are provided on the cantilever beam, and the through holes pass through the upper and lower end surfaces of the cantilever beam. The through holes are arranged opposite to the corresponding gaps, and a row of hooks are respectively provided on the two side walls of the oil tank, and the hooks are arranged opposite to the corresponding gaps. The hooks are located above the through holes facing the same gaps. A pull rod is provided in each gap, and a ring is provided at one end of the pull rod and a threaded rod section is provided at the other end of the pull rod. One end of the pull rod is connected to the corresponding hook through the ring and the other end of the pull rod is screwed to the screw. The threaded rod section and the corresponding through-hole are plugged in and matched, and are connected to the cantilever beam through a pad and a nut. The setting of the pull rod protects and reinforces the heat sink group. When a split-box new energy substation encounters bumpy road conditions during transportation, multiple pull rods protect and reinforce the heat sink group. The setting of the pull rod can also reduce the force generated by the suspension of the heat sink group on the fuel tank, that is, it also protects the fuel tank. At the same time, a split-box new energy substation can be loosened by loosening the nut after arriving at the project site to release the stress generated during tightening; in addition, one end of the pull rod is connected to the corresponding hook through a ring and the other end of the pull rod is connected to the cantilever beam through a pad and a nut after the threaded rod section and the corresponding through-hole are plugged in and matched. This not only facilitates the disassembly and installation of the pull rod, but also facilitates the adjustment of the tensioning force of the pull rod.

[0006] 2. The rubber pad is larger than the through-hole, which is the second technical feature of this utility model. This design aims to reduce stress at the connection between the tie rod and the cantilever beam, thereby further enhancing the tie rod's protective effect on the heat sink assembly.

[0007] 3. The threaded rod segment is also provided with a nut 1, which is located outside the nut. This is the third technical feature of the present invention. The purpose of this design is to prevent the nut from being loosened during transportation by vibration.

[0008] Technical solution: A box-type new energy substation, including a base, a low-voltage box, a high-voltage box and an oil-immersed transformer. A low-voltage box is provided on one side of the upper end surface of the base and a high-voltage box is provided on the other side of the upper end surface of the base. An oil-immersed transformer is provided on the upper end surface of the base and the oil-immersed transformer is located between the low-voltage box and the high-voltage box. A row of heat sink groups are provided on both sides of the oil tank in the oil-immersed transformer, and a heat sink oil pipe is provided at the bottom of each heat sink group. The lower parts of the heat sink oil pipes on the same side are fixedly connected to the upper part of the same cantilever beam. The adjacent heat sink groups in the same row of heat sink groups are connected. There is a gap between the two ends, and a plurality of through holes are provided on the cantilever beam, and the through holes pass through the upper and lower end surfaces of the cantilever beam. The through holes are arranged opposite to the corresponding gaps, and a row of hooks are respectively provided on the two side walls of the oil tank, and the hooks are arranged opposite to the corresponding gaps. The hooks are located above the through holes facing the same gap. A pull rod is provided in each gap, one end of the pull rod is provided with a ring and the other end of the pull rod is provided with a threaded rod section, one end of the pull rod is connected to the corresponding hook through the ring and the other end of the pull rod is connected to the cantilever beam through a gasket and a nut after the threaded rod section and the corresponding through hole are plugged in.

[0009] Compared with the background technology, the present invention has the following advantages: first, a split-box type new energy substation can not only prevent the damage to the heat sink group caused by bumps and vibrations during transportation, but also protect the fuel tank during transportation; second, a split-box type new energy substation can not only facilitate the disassembly and installation of the pull rod, but also the tensioning force of the pull rod can be adjusted.
