A plurality of vertical isolation sheets are arranged on the top surface of the circuit breaker body; the circuit breaker body is installed on a lifting seat. Vertical guide shafts are arranged at the four corner positions of the lifting seat. A positioning frame is arranged on the outer side of the guide shaft. The positioning frame is installed on a fixed seat. A top frame is arranged at the top of the positioning frame. A guide tube is arranged at the outer side position of the top frame.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, a primary-secondary integrated pole-mounted circuit breaker with anti-interference function includes a mounting frame 1 and an upper insulator 2. An auxiliary mechanism 7 is arranged at the front end of the mounting frame 1. The auxiliary mechanism 7 includes a fixing frame 71 fixedly connected to the front end of the mounting frame 1. One end of the fixing frame 71 is fixedly connected with a guiding plate 72. A connecting rod 73 is slidably connected inside the guiding plate 72. A linkage piece 74 is fixedly connected to the outside of the connecting rod 73. An amplitude piece 75 is fixedly connected to the front end of the linkage piece 74. A supporting piece 76 is fixedly connected to the front end of the amplitude piece 75. A limiting piece 77 is fixedly connected to the front end of the supporting piece 76. A docking frame 78 is fixedly connected to the front end of the limiting piece 77. A connecting rope 79 is fixedly connected to the inside of the docking frame 78. A vibration ball 710 is fixedly connected to the lower end of the connecting rope 79.

[0022] In this embodiment, a linkage rod 711 is slidably connected inside the guiding plate 72 near the front side of the connecting rod 73. The shape of the amplitude piece 75 is Z-shaped, and the middle position of the amplitude piece 75 is narrower. The shape of the limiting piece 77 is arc-shaped. The number of the docking frame 78, the connecting rope 79 and the vibration ball 710 are all multiple groups. Both the upper and lower ends of the linkage rod 711 are fixedly connected to the inner wall of the supporting piece 76. The number of the linkage piece 74 and the amplitude piece 75 are both multiple groups. The material of the amplitude piece 75 is metal material.

[0023] Specifically, in windy weather, the strong wind blows up foreign objects on the ground, causing the wind to blow up the vibrating ball 710, making the vibrating ball 710 swing up and down, and causing the vibrating ball 710 to drive the limiting piece 77 through the connecting rope 79 and the docking frame 78. Furthermore, the supporting piece 76 drives the linkage rod 711 and the connecting rod 73 to move up and down. Since the middle part of the amplitude piece 75 is relatively narrow, the amplitude piece 75 generates vibrations during the up and down movement, emitting vibration waves around the upper insulator 2, so that foreign objects cannot touch the upper insulator 2. By the strong wind blowing up the vibrating ball 710 and making the vibrating ball 710 swing up and down, the supporting piece 76 moves up and down, and the amplitude piece 75 generates vibrations, which can achieve the purpose of facilitating the vibration of the amplitude piece 75 around the upper insulator 2, thereby emitting vibration waves around the upper insulator 2, so that foreign objects cannot touch the upper insulator 2, and further achieving an anti-interference effect on the upper insulator 2.

[0024] In this embodiment, the upper insulator 2 is installed in the inner side of the front end of the mounting frame 1 close to the fixing frame 71. The middle insulator 4 is installed at the lower end of the upper insulator 2. The lower end of the mounting frame 1 is fixedly connected to the connecting frame 3. The lower insulator 5 is installed at the lower end of the middle insulator 4. The lower insulator 6 is installed at the rear end of the knife switch body 5. The rear end of the lower insulator 6 is installed at the front end of the connecting frame 3.

[0025] Specifically, the mounting frame 1 is installed on the electric pole, and the upper insulator 2, the middle insulator 4, the knife switch body 5, and the lower insulator 6 are located in the air, thus completing the installation.

[0026] Working principle:

[0027] During use, first install the mounting frame 1 on the electric pole, and the upper insulator 2, the middle insulator 4, the knife switch body 5, and the lower insulator 6 are located in the air, thus completing the installation. In windy weather, the strong wind blows up foreign objects on the ground, causing the wind to blow up the vibrating ball 710, making the vibrating ball 710 swing up and down, and causing the vibrating ball 710 to drive the limiting piece 77 through the connecting rope 79 and the docking frame 78. Furthermore, the supporting piece 76 drives the linkage rod 711 and the connecting rod 73 to move up and down. Since the middle part of the amplitude piece 75 is relatively narrow, the amplitude piece 75 generates vibrations during the up and down movement, emitting vibration waves around the upper insulator 2, so that foreign objects cannot touch the upper insulator 2. By the strong wind blowing up the vibrating ball 710 and making the vibrating ball 710 swing up and down, the supporting piece 76 moves up and down, and the amplitude piece 75 generates vibrations, which can achieve the purpose of facilitating the vibration of the amplitude piece 75 around the upper insulator 2, thereby emitting vibration waves around the upper insulator 2, so that foreign objects cannot touch the upper insulator 2, and further achieving an anti-interference effect on the upper insulator 2.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
