In recent years, with the rapid social and economic development and the implementation of the national policy of benefiting the people, the rural economy has entered the fast lane of development. A large number of household appliances such as air conditioners and refrigerators have entered the homes of rural people and the small industries in rural areas Rise, but also led to the rapid growth of rural economy, but also on the rural distribution network power supply and power supply reliability put forward higher requirements.

For many years, Jieshou Company continued to intensify the reform of rural power network for agricultural distribution network lines. At present, the trunk line of 10 kV distribution lines has been insulated and completed. 260 vacuum circuit breakers, 155 sets of fuses, 10 kV The average line protection equipment for the 5.4 units / Article, nevertheless, the overall technical level of 10 kV rural power network distribution lines is still low, the line
