Analysis of low temperature environment on backup battery performance of automatic terminal of distribution network

In order to improve the battery use performance of the backup power supply of the distribution network automation terminal in the low-temperature environment, This paper analyzes the battery capacity performance of the power distribution automation terminal in low temperature environment. The influence of different temperatures on the performance of lead-acid battery is analyzed by the data, and put forward the distribution network automation terminal operation and maintenance of backup power supply and maintenance measures. It provides a firm foundation for the safe and reliable operation of distribution network automation equipment in low temperature environment.
