基于单片机控制的10kV联络柜馈线指示技术

Feeder Lines Indicating Technology for 10kV Coupling Switchgear Based on Micro Controller Unit

环网运行的电缆配电网络利用联络柜实现不同馈线之间的互联。基于单片机基础研究了10 kV联络柜馈线指示技术,分别提取10 kV联络柜自身及其所属配电房进线柜的开关开合状态、电缆带电状态作为输入量,经单片机处理后,分别输出联络柜母线和电缆的带电状态以及所属馈线。研制出了相应的指示器产品,经现场应用表明,该馈线指示技术具有可行性,有效降低了现场作业人员的误操作风险。

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.
