Study On Lightning Protection Of 6KV Line In Mine Special Line

In recent years,the 6kV line in Pingdingshan mining area has been repeatedly hit by lightning and caused an accident,and the trend is increasing,and the scope of the injured line is expanding.As an important user of the power system,the safety and reliability of the production of coal enterprises is not only related to the economic benefits of the enterprises,but also on the life and safety of many workers under the mine.Therefore,the lightning protection reform of the 6kV line in Pingdingshan mining area is imminent.Based on the current situation of the 6kV line in Pingdingshan mining area,this paper takes the existing lightning knowledge and lightning protection technology as the theoretical basis for the study,and puts forward some suggestions on Lightning Protection in combination with the actual situation in Pingdingshan mining area.A typical tower type is set up,and the horizontal offset distance between the lightning conductor and the conductor is checked,whether the protection angle and the lightning protection level of the lightning conductor to the side conductor are satisfied.The computer software simulation provides data support for the actual line to strengthen insulators according to local conditions.2 typical lines are selected as the technical test points to be reformed to compare the lightning protection effect before and after the transformation of the line.After 2 thunderstorm periods,the lightning trip accident has not occurred,and the test is qualified,which can be used as a demonstration line.Therefore,the typical towers and towers built in this paper can be modeled according to the transformation of the subsequent lines,and the parameters can be corrected by reference to the operation of the transformation lines.
