With the development of urban transportation, the safety and efficiency of subway operation as an important part of urban public transportation have attracted more and more attention. In the construction of subways, in order to ensure the safety and stability of train operation, a series of measures need to be taken to reduce the impact of electromagnetic interference. Among them, the embedded degaussing tube is a common measure, which is used to reduce the strong magnetic field near the subway track and avoid interference with communication, navigation and other equipment.
1. The impact of electromagnetic interference on subway operation.
During the operation of the subway, strong electromagnetic fields are generated by the vehicles and tracks. These electromagnetic fields may interfere with nearby communications, television, mobile communications and other equipment, affecting people's normal life and work. At the same time, excessively strong electromagnetic fields can also have an impact on the control system of metro vehicles, leading to train failures or accidents. Therefore, it is necessary to take effective measures to reduce the effects of electromagnetic interference.
Second, the role of embedded orbit degaussing tube.
The embedded over-rail degaussing tube is a kind of degaussing equipment specially used for subway tracks. Its main function is to reduce the magnetic field present in the vicinity of the orbit, thereby reducing the effects of electromagnetic interference. The equipment is made of high magnetic permeability materials, by laying pipes under the track, the pipe is filled with magnetic materials, the magnetic permeability of magnetic materials is used to introduce the magnetic field on the track into the pipe, and the magnetic field is eliminated or reduced through the special design of the pipeline.
Third, the advantages of embedded rail degaussing tube.
Compared with the traditional degaussing method, the embedded over-orbit degaussing tube has the following advantages:
1.Reduce the interference range: The embedded over-orbit degaussing tube can greatly reduce the magnetic field near the track, thereby reducing the interference range to the surrounding equipment.
2.Effectively improve communication quality: By reducing the magnetic field near the track, the signal quality of communication equipment can be significantly improved, and people's communication experience can be improved.
3.Reduce maintenance costs: The embedded demagnetization tube has a long service life and low maintenance cost, which can save a lot of maintenance costs for subway operators.
4.Improve safety: By reducing the impact of electromagnetic interference, train failures or accidents can be avoided and the safety of subway operation can be improved.
Fourth, the future development of embedded orbit degaussing tubes.
With the continuous progress of technology and the continuous improvement of application requirements, embedded rail degaussing tubes will be more widely used in future subway construction. Future directions include:
1.Material optimization: Continuously improve the quality and performance of high permeability materials, improve the degaussing effect and the service life of the equipment.
2.Intelligent management: Through the introduction of intelligent technology, real-time monitoring and remote control of the embedded rail degaussing tube can be realized, and the operation efficiency and safety of the equipment can be improved.
3.Customized design: According to the actual situation and needs of different cities and different lines, customized design and optimization are carried out to meet the application needs in specific scenarios.
4.Environmental protection and energy saving: In the process of equipment production and operation, pay attention to the application of environmental protection and energy-saving technology to reduce the impact on the environment.
In summary, as an effective measure to reduce electromagnetic interference, the embedded over-rail degaussing tube has a wide application prospect in subway construction. With the continuous progress of technology and the continuous improvement of application requirements, the embedded orbital degaussing tube will be more widely used and developed in the future.
