[0002] As the main equipment in the UHV DC transmission project, the UHV dry-type air-core smoothing reactor is connected in series in the system and is an indispensable key main equipment for the normal operation of the converter station. It plays an important role in limiting the overcurrent when the voltage collapses on the inverter side, smoothing the ripple in the transmitted DC current, preventing the overvoltage along the DC line from invading the converter station and affecting the insulation of the converter valve, and maintaining the uninterrupted DC current under low load conditions.

[0003] In recent years, it has been found that bird activities have seriously affected the normal operation of converter station equipment in many places, especially for large dry-type hollow smoothing reactors.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The embodiments described in this application are only part of the embodiments of the utility model, not all of them. Based on the spirit of the utility model, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.

[0026] A dry-type hollow smoothing reactor fully surrounded by bird-proof device:

[0027] It includes a connecting support 1, an arc-shaped bird-proof mesh 2, an upper noise reduction device 3, a middle noise reduction device 4, a lower noise reduction device 5 and fasteners;

[0028] A certain number of connecting supports 1 are arranged on the surface of the dry-type hollow smoothing reactor noise reduction device, and a bird-proof mesh is installed on the outer facade of the connecting support 1. The bird-proof mesh has an arc that matches the outer diameter of the noise reduction device, so that the gaps between the layers of the noise reduction device are surrounded and closed.

[0029] Preferably, the connecting support 1 adopts an "L"-shaped structure, which is composed of a right-angle horizontal bar and a vertical vertical bar made of 304 stainless steel.

[0030] Preferably, the connecting supports 1 are evenly arranged on the surface of the noise reduction device, and the connecting supports 1 are respectively located on the lower surface of the upper noise reduction device 3, the upper surface of the middle noise reduction device 4, the lower surface of the middle noise reduction device 4, and the upper surface of the lower noise reduction device 5, forming a uniform cylindrical shape on the entire bird-proofing device.

[0031] Preferably, the upper noise reduction device 3, the middle noise reduction device 4 and the lower noise reduction device 5 are respectively located on the upper surface, the middle layer and the lower surface of the entire device, and are arranged to form vertical layers of the bird-proofing device.

[0034] The L-shaped structural design enables the connecting support to provide stable support, making the entire bird-proofing device stable. The setting of the connecting support helps to maintain the correct position of the bird-proofing mesh, so that it can effectively close the gaps between the layers of the noise reduction device.

[0035] Preferably, the middle-layer noise reduction device 4 comprises a circular hollow structure composed of six fan-shaped top cover end surfaces and six arc-shaped top cover inner side walls;

[0036] The connecting support 1 is arranged on the upper and lower surfaces outside the middle layer noise reduction device 4, and is connected to the arc-shaped bird-proofing mesh 2 through the L-shaped structure of the connecting support 1 using stainless steel fasteners with pressure-equalizing shielding caps to prevent external discharge.

[0043] Preferably, the conductive component is a slender wire or a flat conductive plate.

[0044] Suspended potential refers to the potential difference that may occur at points in the electric field that are not directly grounded or equipotentially connected. By connecting the support to the internal equipotential line of the noise reduction device, the formation of suspended potential can be prevented, the electric field in the entire system is evenly distributed, and the electrical stability of the equipment is maintained.

The utility model arranges a certain number of connecting supports on the surface of the existing dry hollow smoothing reactor noise reduction device, and the bird-proof mesh with a curvature designed according to the outer diameter of the noise reduction device can be directly installed on the outer facade of the connecting support. Multiple bird-proof meshes form a cylindrical structure, which surrounds and closes the gaps between the layers of the noise reduction device, can prevent birds from flying into the noise reduction device, and solve the hidden danger of birds affecting the operation of the reactor.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
