Why is the degaussing elbow bent
Degaussing elbow is a common device in the power system, which is used to convert a straight transmission line into a curved transmission line, so as to realize the bending and turning of the line. The reason why the degaussing elbow is bent is mainly based on the following considerations:
First of all, the curved shape of the degaussing elbow can eliminate the influence of the magnetic field. In transmission lines, the current creates a magnetic field around the conductor, especially in a straight transmission line, where the direction and magnitude of the magnetic field are relatively uniform. However, where the transmission line is bent, the magnetic field changes, causing the distribution of the magnetic field to become uneven. The curved shape of the degaussing elbow can effectively eliminate this uneven magnetic field distribution and reduce the impact of the magnetic field on the surrounding environment and equipment.
Secondly, the design of the degaussing elbow can reduce the reactance and resistance of the line. In transmission lines, resistance and reactance are parameters that are proportional to the length of the line. The effects of resistance and reactance are particularly significant in long-distance transmission lines. The design of the degaussing elbow can reduce the bending radius of the line, thereby reducing the length of the line, further reducing the resistance and reactance of the line, and improving the transmission efficiency.
In addition, the degaussing elbow can also reduce the mechanical stress of the line. In transmission lines, electromagnetic forces are generated due to the passage of electric current, which causes the lines to be subjected to mechanical stress. Especially where the road is bent, the mechanical stress will be more concentrated. The design of the degaussing elbow can reduce the bending radius of the line, thereby reducing the mechanical stress on the line and ensuring the safe and stable operation of the line.
To sum up, the reason why the degaussing elbow is bent is mainly to eliminate the influence of the magnetic field, reduce the resistance and reactance of the line, and reduce the mechanical stress of the line. In the modern power system, the degaussing elbow has been widely used, which plays an important role in ensuring the safe and stable operation of the power system.
