摘 要：環網運行的電纜配電網絡利用聯絡柜實現不同饋線之間的互聯。基于單片機基礎研究了10 kV聯絡柜饋線指示技術，分別提取10 kV聯絡柜自身及其所屬配電房進線柜的開關開合狀態、電纜帶電狀態作為輸入量，經單片機處理后，分別輸出聯絡柜母線和電纜的帶電狀態以及所屬饋線。研制出了相應的指示器產品，經現場應用表明，該饋線指示技術具有可行性，有效降低了現場作業人員的誤操作風險。
關鍵詞：聯絡柜；配電網；單片機；帶電狀態；饋線指示

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.
Key words: coupling switchgear; distribution network; micro controller unit; energized state; feeder indicate
