Abstract
Aiming at the problems of the 10 kV distribution network such as short feed line
big loadand many subsection in feed line of ring main unit
analyzes the cause and puts forward solving proj?ect. The improvemenf result shows that using local protection device
by higher and lower protectiondevices closedown
can advance the selectivity of switch trip in 10 kV distribution network
