[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1 to 5 The present invention provides a corrosion-resistant wind power busbar structure based on a sulfurized composite insulation layer, comprising a tubular busbar body 1, a connector 2 fixedly provided at one end of the tubular busbar body 1, a plug plate 3 fixedly provided at the other end of the tubular busbar body 1, and two adjacent tubular busbar bodies 1 being connected by a number of bolts 4 and U-shaped limiting sleeves 5.

[0024] The bolt 4 and the U-shaped limiting sleeve 5 can make the connector 2 and the plug plate 3 securely connected, avoiding loosening and poor contact.

[0025] The tubular busbar body 1 is composed of a tubular conductor 6, a silicone rubber insulating inner layer 7, a copper foil shielding inner layer 8, a high-temperature vulcanized EPDM rubber insulating layer 9, a corrosion-resistant microporous silicone buffer layer 10, an aluminum foil insulating outer layer 11, and a fluorinated ethylene propylene copolymer protective sleeve 12. The silicone rubber insulating inner layer 7 covers the outer surface of the tubular conductor 6, the copper foil shielding inner layer 8 covers the outer surface of the silicone rubber insulating inner layer 7, the high-temperature vulcanized EPDM rubber insulating layer 9 covers the outer surface of the copper foil shielding inner layer 8, the corrosion-resistant microporous silicone buffer layer 10 covers the outer surface of the high-temperature vulcanized EPDM rubber insulating layer 9, the aluminum foil insulating outer layer 11 covers the outer surface of the corrosion-resistant microporous silicone buffer layer 10, and the fluorinated ethylene propylene copolymer protective sleeve 12 covers the outer surface of the aluminum foil insulating outer layer 11.

[0026] The silicone rubber insulating inner layer 7, the high-temperature vulcanized EPDM rubber insulating layer 9, the corrosion-resistant microporous silicone buffer layer 10, and the fluorinated ethylene propylene copolymer protective sleeve 12 can improve corrosion resistance and buffering performance. The copper foil shielding inner layer 8 and the aluminum foil insulating outer layer 11 can provide shielding to prevent the insulation layer from being broken down.

[0027] The tubular conductor 6 is made of either copper or aluminum.

[0028] The connector 2 is composed of a first snap-fit ​​plate 13 and a second snap-fit ​​plate 14. A snap-fit ​​groove 15 matching the plug-in plate 3 is formed between the first snap-fit ​​plate 13 and the second snap-fit ​​plate 14, which can be tightly connected with the plug-in plate 3.

[0029] The plug-in plate 3, the first snap-fit ​​plate 13, and the second snap-fit ​​plate 14 are connected by an interference fit, which can improve the stability of the contact and prevent loosening.

[0030] The U-shaped limiting sleeve 5 has a limiting head 16 and a limiting head 27 that are matched with the first snap plate 13 and the second snap plate 14 respectively fixedly installed on one end of each side of the U-shaped limiting sleeve 5 near the opening. These limiting heads can form a limiting effect with the first snap plate 13 and the second snap plate 14, further improving the stability of the connection between the plug plate 3 and the first snap plate 13 and the second snap plate 14.

[0031] Both the first snap-fit ​​plate 13 and the second snap-fit ​​plate 14 have bolt connection holes 18 that match the bolt 4, and the plug-in plate 3 has bolt connection holes 19 that match the bolt 4, which facilitates the installation of the bolt 4.

[0032] In operation, by setting up a tubular busbar body composed of a tubular conductor, a silicone rubber insulating inner layer, a copper foil shielding inner layer, a high-temperature vulcanized EPDM rubber insulating layer, a corrosion-resistant microporous silicone buffer layer, an aluminum foil insulating outer layer, and a fluorinated ethylene propylene copolymer protective sleeve, the overall corrosion resistance can be improved, while also providing buffering and shielding performance. By setting up a connector consisting of a first snap-fit ​​plate and a second snap-fit ​​plate, and ensuring that the plug-in plate is interference-fitted with the first and second snap-fit ​​plates, a tight fit can be achieved, preventing poor contact due to loose bolts. By setting up a U-shaped limiting sleeve, a limiting head one, and a limiting head two, the first and second snap-fit ​​plates can be limited, further improving the tightness of the connection between the first and second snap-fit ​​plates and the plug-in plate.
