Embodiment
[0015] Such as figure 1 As shown, the inclination indicating device for the linear insulator of the transmission line pole tower. The main body of this device is a semicircular dial with a rotating pointer on it. The material can be PVC composite material. The pointer on the semicircular dial is connected to the upper part of the linear insulator The neck of the linear insulator is connected and fixed, so that when the linear insulator is tilted, the pointer will also deflect together, and it will be displayed intuitively on the scale plate, which can reflect the degree of inclination of the linear insulator.
[0016] Concrete use process of the present invention is as follows:
[0017] 1 Put the inclination indicating device of the straight line insulator of the transmission line pole tower according to the attached figure 1 The marked position is installed at the upper cross arm of the linear insulator string, and the tilt indicating device dial (1) made of PVC composite ma...

The invention relates to a tilt indicating device for a straight insulator of an electric transmission line tower. The tilt indicating device is characterized in that a dial (1) is fixed at the edge of a cross arm above the straight insulator through a U-shaped clip (3) of the indicating device, and an insulator tilt indicating pointer (2) is arranged on the dial (1) and penetrates through the dial (1) through a connecting rod (5) to be connected with the straight insulator behind the dial (1) and fixed through a clamp (5). The indicating device is applied to an overhead transmission line straight tower and can intuitively reflect the tilt degree of the straight insulator through the pointer, help line inspectors to see the tilt condition of the insulator of the straight tower, and reduce the times of line transportation and inspection people climbing the tower for measurement. The indicating device conforms to the principles of science, actual effect, economy and specification and can ensure the safe and stable operation of a power grid.
Description
technical field [0001] The invention relates to an insulator tilt indicating device on a straight pole tower in a power transmission line of a power system. The bird prevention device can be applied to a straight pole tower of an overhead power transmission line with a voltage level of 66 kV or above. Background technique [0002] According to the provisions of 7.6.6 in 7.6 Attachment Installation of 7 Wire Projects in the "Code for Construction and Acceptance of Overhead Transmission Lines", after the suspension clamps under the linear insulator strings are installed on the straight line towers of the transmission line, the linear insulator strings should be perpendicular to the ground plane In individual cases, the offset angle between the line and the vertical position should not exceed 5°, and the maximum offset value should not exceed 200mm. However, after the construction of the transmission line is completed, the linear insulators and suspension clamps on some towers ...
