Referring to fig. 1-6, the present invention provides a technical solution:

the invention provides a self-cleaning type transformer bushing anti-fouling cover, which is provided with an anti-fouling cover 2 and a protective cylinder 3 in order to keep a transformer bushing clean and facilitate inspection. The outer side of the transformer bushing 1 is provided with a plurality of round tables 10 at equal intervals for reflecting the kilovolt number of the transformer, namely, the plurality of round tables 10 are a plurality of kilovolt. The top of the transformer bushing 1 is provided with an antifouling cover 2, and the outer side of the transformer bushing 1 is provided with a protective cylinder 3. The dirt protector 2 comprises a left shroud 20 and a right shroud 25 in a semi-circular block structure. An inner cavity 21 with a semicircular block structure is formed in the center of the vertical surface of the left protective cover 20 and is used for covering the circular truncated cone 10. The vertical face top corner of left guard shield 20 is equipped with ring cover 22, and the axis of ring cover 22 is located the top limit line of the vertical face of left guard shield 20 for left guard shield 20 and right guard shield 25 rotate the laminating closely. The bottom center of the left shield 20 is provided with a semicircular ring platform 23 communicated with the inner cavity 21, and the inner diameter of the semicircular ring platform 23 is smaller than the outer diameter of the circular platform 10, so that the circular platform 10 can be trapped, and the antifouling cover 2 is prevented from being upwards pulled out after being connected with the protective barrel 3. The bottom outside of semicircle ring platform 23 is equipped with semicircle platform 24, and the lateral surface of semicircle ring platform 24 is equipped with external screw thread 240, and the vertical face of right guard shield 25 just is close to central department symmetry and is equipped with lantern ring 26, and lantern ring 26 and ring cover 22 butt joint and inside all peg graft and have pin 4 for both relative rotations of left guard shield 20 and right guard shield 25 are drawn close. The inner side of the top end of the protection cylinder 3 is provided with an inner thread 30, and the inner thread 30 is in threaded connection with the outer thread 240, so that the anti-fouling cover 2 and the protection cylinder 3 are connected into a whole to protect the transformer bushing 1.

In this embodiment, the anti-fouling cover 2 and the protection cylinder 3 are made of ABS material and are integrally formed, so that they are tough, high temperature resistant, and rigid, and are durable.

Further, the inner and bottom structures of the right shield 25 and the left shield 20 are the same, the sizes of the right shield 25 and the left shield 20 are also the same, and only the positions of the circular sleeve 22 and the lantern ring 26 are different, so that the circular truncated cone 10 is wrapped by the left shield 20 and the right shield 25 which are close to each other to form a full circular structure.

Specifically, the top surfaces of the right shield 25 and the left shield 20 and the center of the vertical surface are provided with an avoiding opening 200 communicated with the inner cavity 21 to avoid a boss at the top end of the transformer bushing 1, and an electric wire can penetrate through the inside of the avoiding opening.

Specifically, the inner diameter of the inner cavity 21 is larger than the outer diameter of the circular truncated cone 10, so that when the left protective cover 20 and the right protective cover 25 are overturned to approach the circular truncated cone 10, space is available, and interference and jamming are avoided.

In addition, the distance between the bottom surface of the inner cavity 21 and the bottom surface of the half ring platform 24 is equal to the distance between the two circular platforms 10, so that the anti-fouling cover 2 is stable between the circular platforms 10 and does not shake.
