    Abstract: The cable distribution network of looped network operation takes advantage of the coupling switchgear to realize the interconnection between different feeder lines. On the basis of the micro controller unit, this paper researched on the 10 kV coupling switchgear feeder lines indicating technology and extracted the 10 kV coupling switchgear itself and the switch open-close state of belonging switch board room coil in cabinet and the cable electrification state as input respectively. After the micro controller unit was disposed, it output the electrification state and its belonging feeder lines of the output coupling switchgear bus bar and cable respectively. This paper developed the corresponding indicator products. The onsite application shows that this feeder lines indicating technology possesses feasibility and effectively reduces the misoperation risk of onsite operating personnel.
