[0039] The anti-bird nesting protection sleeve for the single-arm horizontal rotary disconnector provided by the embodiment of the present invention includes a left protective cover and a right protective cover.

[0040] The left protective cover includes a left half shell 1 for buckling one side part of the grooved conductive rod 7, a left bellows 3 for buckling one side part of the crank mechanism, and a left annular shell 5 for buckling the upper part of one side of the insulator string rod 8.

[0041] The right protective cover includes a right half shell 2 for buckling the other side part of the grooved conductive rod 7, a right bellows 4 for buckling the other side part of the crank mechanism, and a right annular shell for buckling the upper part of the other side of the insulator string rod 8.

[0042] The left protective cover and the right protective cover are buckled on the upper parts of the grooved conductive rod 7, the crank mechanism and the insulator string rod 8 and are fixedly connected by a buckle.

[0043] Side covers 6 for plugging are provided in both of the two slots formed by buckling the left protective cover and the right protective cover on the grooved conductive rod 7.

[0045] Moreover, by adopting a bellows, the designed structure of the bellows has flexibility and does not affect the opening and closing operations of the disconnector. When the single-arm horizontal rotary disconnector flips, it can follow the stretching without pulling and damaging the protective sleeve, thus extending the service life.

[0046] Specifically, one side of the left half-shell 1 is connected to one side of the right half-shell 2. The other side of the left half-shell 1 is sequentially connected to the left bellows 3 and the left annular shell 5. The other side of the right half-shell 2 is sequentially connected to the right bellows 4 and the right annular shell.

[0051] To further optimize the above solution, both the left protective cover and the right protective cover are made of soft materials. It can prevent danger caused by falling from a height and has good adaptability to the flipping action of the single-arm horizontal rotary disconnector.

[0052] Specifically, both the left protective cover and the right protective cover are made of vulcanized silicone rubber. Both the left protective cover and the right protective cover are insulating materials. For example, HTV high-temperature vulcanized silicone rubber is adopted, which is flame-retardant, aging-resistant, and has a service life of 20 years. Moreover, the vulcanized silicone rubber has high insulation and will not affect the operating conditions of the disconnector.

[0053] Specifically, after the left half-shell 1 and the right half-shell 2 are buckled, they form a rectangular body to accommodate the grooved conductive rod 7. After the left bellows 3 and the right bellows 4 are buckled, they form a rectangular body to accommodate the crank mechanism. After the left annular shell 5 and the right annular shell are buckled, they form a cylindrical body to accommodate the upper part of the insulator string rod 8.

[0054] Among them, locking edges 10 are provided on both the left protective cover and the right protective cover, and a plurality of locking holes are provided on the locking edges 10. The locking holes are connected by lock catches. The locking holes are arranged at equal intervals.
