Problems solved by technology
In the existing medium-voltage communication technology, external medium-voltage capacitors are often used as the construction method of the communication link. However, during installation, operation and maintenance, and fault repair of this kind of communication link, power failure is required before subsequent operations can be carried out. The economic losses caused by power outages are huge, causing great unnecessary waste, and there are many inconveniences in equipment overhaul and maintenance, which has brought many obstacles to the robust development of medium-voltage power communication lines
If only this method is used to build medium-voltage communication links, the construction method is single, which is not conducive to long-term communication use

Description
technical field [0001] The invention relates to a networking method for realizing medium-voltage communication by using a lightning arrester. Background technique [0002] Medium-voltage power line communication technology refers to the use of medium-voltage power lines (usually 10KV voltage level) in the power transmission network as the signal transmission medium for the transmission of voice and data information. This technology is applied to the automatic data transmission platform of the medium voltage distribution network; in recent years, the medium voltage power line broadband network access is attracting more and more attention due to its complete infrastructure, wide distribution and low cost, especially It has strong practical value in remote rural areas or sparsely populated areas. In the existing medium-voltage communication technology, external medium-voltage capacitors are often used as the construction method of the communication link. However, during instal...
