Anti-vibration hammer for monitoring wind load of overhead transmission line

Abstract

The invention provides an anti-vibration hammer for monitoring the wind load of an overhead transmission line. The hammer comprises a left hammer body, a right hammer body and a connecting rod. The left hammer body and the right hammer body are connected through a connecting rod; the outer surface of the left hammer body is provided with wind pressure sensors; the wind pressure sensors surround the left hammer body for a circle and are used for measuring wind pressure in all directions on the surface of an anti-vibration hammer body; a motion measuring device is installed in the left hammer body and used for measuring the acceleration and angular acceleration of motion; a communication device is further installed in the left hammer body; a battery is installed in the right hammer body andused for providing electricity for other devices; and a central processing device is arranged in the right hammer body and used for collecting and processing data. According to the invention, the outer diameter of a hammer head of the anti-vibration hammer is consistent with the outer diameter of the wire, and the hammer head of the anti-vibration hammer is equipped with the wind pressure measuring sensors for measuring the wind pressure of each position of the circumference of the hammer head of the anti-vibration hammer, so that the actual stress direction and magnitude of the wire are accurately measured, and windage yaw or galloping states of the wire are monitored.

Description

technical field [0001] The invention belongs to the field of power transmission equipment, in particular to an anti-vibration hammer used for wind load monitoring of overhead power transmission lines. Background technique [0002] Affected by weather conditions such as wind, ice, and low temperature, overhead power lines are prone to vibration. If the vibration frequency is high and the amplitude is small, the overhead wire will be repeatedly bent at the suspension point, causing material fatigue, and eventually leading to broken strands and broken wires. If the vibration frequency is very low but the amplitude is large, it is easy to cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burning of wires. In order to avoid the above problems, the anti-vibration hammer can be hung on the suspension point of the line tower rod to absorb or weaken the vibration energy, change the swing frequency of the line, and prevent the line...
