As we all know, the high-voltage electric poles are very high from the ground, and the distance between the poles is very far. When the wind is strong, it will cause the line to shake vigorously. Over time, it will cause the wire to be damaged and the line to break, which will affect the safe power supply. Therefore, in order to reduce the occurrence of such incidents, a small hammer will be hung on the line, hanging at the position where the pressure wire is close to the porcelain bottle. This small hammer has a scientific name, called "vibration damper". From the name, we can know vibration damper function. Shock-absorbing hammer protective rod ismainly set to prevent the wire from vibrating in windy weather.
The power overhead line is affected by meteorological conditions such as wind, ice, and low temperature, causing the line to vibrate and dance. The vibration frequency is high and the amplitude is small. The wind vibration causes the overhead line to be repeatedly bent at the suspension point, causing wire fatigue, and finally leading to strand and wire breakage accidents. The dancing frequency is very low, but the amplitude is very large, which can easily cause serious accidents such as line tripping, power outages, or wire burns. The vibration damper is a section of iron rod.Shock-absorbing hammer protective rod is hung at the suspension point of the line tower to absorb or weaken the vibration energy, change the line swing frequency, and reduce the vibration or dancing of the line. When the wire is vibrated by wind or other reasons, the fastener connection at the end of the wire will be subjected to strong impact force, which is the most destructive. However, after the wire is equipped with an vibration damper, the natural frequency between the wire and the fastener is destroyed, reducing or eliminating the mechanical damage caused by vibration or swinging in this part, increasing the service life, and ensuring the safety and reliability of power supply.
When the vibration amplitude of the wire is too large, it will not only affect the stability of the line, but also damage the insulator. Therefore, when the adjacent poles are more than 120 meters, Shock-absorbing hammer protective rods are installed on the wires on both sides of the insulator to offset the vibration energy by generating movement in the opposite direction of the wire vibration, thereby effectively protecting the safety of the line equipment. In other words, the role of the shock-absorbing hammer protective rod is to neutralize the vibration of the wire through reverse movement to ensure the smooth operation of the transmission line.
Now it is understood that the hammer hanging on the high-voltage overhead line is not an ordinary hammer, and its role cannot be underestimated. The vibration damper produced by our company is popular and well received. It can maintain a stable protective effect in long-term operation.Vibration damper is suitable for various mechanical equipment, construction, transportation tools and other scenes.Shock-absorbing hammer protective rod is widely used in mining, metallurgy, construction, automobile and other industries.
