U type bolt component for mounting electric power line on-line apparatus

Abstract

The invention discloses a U-shaped bolt component for mounting a power circuit on-line device. The bolt component is used for fixedly mounting the on-line device on a high-voltage pylon angle iron; the bolt component comprises a U-shaped bolt, nuts matched with the U-shaped bolt, and bolt cover plates; a straight rod of the U-shaped bolt is sleeved with a first bolt cover plate, a first nut, a second nut, a second bolt cover plate, a third bolt cover plate and a third nut in sequence; the first bolt cover plate and the first nut are used for clamping a center shaft lever of the on-line device and the inside surface of a U-shaped elbow of the U-shaped bolt; and the second bolt cover plate and the third bolt cover plate are positioned at two sides of the angle iron respectively, and the angle iron is clamped between the second bolt cover plate and the third bolt cover plate through the second nut and the third nut. The U-shaped bolt assembly can ensure that the shaft lever keeps vertical when the on-line device is arranged.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a U-bolt assembly used for installing power line on-line devices. Background technique [0002] In order to detect meteorological parameters such as temperature, humidity, rainfall and other parameters in the area where the power line passes, online devices such as weather stations need to be installed in the power line. [0003] At present, the installation of online devices in the power system is generally done with the help of built iron towers or gantry frames. Fix the online device on the angle iron of the high-voltage iron tower through U-shaped bolts. [0004] In order to ensure the accuracy of the measurement data of the online device, when installing the online device in the power line, it is clearly required that the central axis must be vertical when the online device is installed. For example, the "Specifications for Surface Meteorological Observation" clearly stipulate...

AI Technical Summary

Problems solved by technology

[0010] From the above analysis, it can be seen that the installation method described in the prior art cannot realize the vertical central axis when the online device is installed, resulting in large errors in the measurement data of the online device

For example, for the wind speed sensor, if the central axis is inclined during installation, due to the weight of the wind cup itself, a torque will be generated on the rotation plane of the wind cup, which will affect the rotation of the wind cup and thus affect the accuracy.
