The 220kV transmission line is the most important high-voltage transmission line in China's power system and plays an important role in the power supply and social development in various regions.
In order to ensure the safe and stable operation of 220kV transmission lines, it is necessary to simplify the complex network structure of 220kV transmission lines as much as possible, optimize and improve the design of 220kV transmission lines, and improve the reliability of transmission lines.
When planning and designing 220kV transmission lines, you can choose the way of cat head towers or dry towers, single circuit design of transmission lines, reduce the floor area and width of 220kV transmission line corridors.
The influence of electromagnetic radiation on 220kV transmission lines mainly includes interference to radio and electric field effects.
In order to better control the influence of electromagnetic radiation on 220kV transmission lines, the voltage and current control of transmission lines are strengthened.
And the towers and electrical insulation of 220kV transmission lines are strictly controlled.
The cooperation between the equipment should reasonably set the distance between the ground and the tower and take effective measures to detect the operating status of the transmission line in order to avoid safety accidents and affect people's life safety.
For the design of 220kV transmission line, attention should be paid to the evaluation of geological disasters, hydrogeological impact assessment, flood control impact assessment, cultural heritage protection assessment.
And earthquake safety evaluation of a transmission line to the surrounding environment.
