摘要（英）：

The invention discloses an electricity transmission insulator arc-over on-line monitoring and safety early-warning device which can timely find out arc-over of an insulator and early warn the fault or give an alarm to the fault. The device comprises an electric leakage arc-over image monitoring unit 101, an arc-over image extraction unit 102, an arc-over electric current detection unit 111, an arc-over data processing unit 112, a weak electric current leakage detection unit 121, a weak signal processing unit 122, and an embedded type core processor 151. The weak electric current leakage detection unit is used for monitoring the weak changes of the insulator when the insulator works, the arc-over electric current detection unit is used for finding out the electric current changes in the arc-over process of the insulator, the arc-over image monitoring unit and the arc-over image extraction unit are used for giving out an image-extraction instruction when the arc-over electric current reaches the preset grade, and the weak signal processing unit, the arc-over data processing unit and the arc-over image extraction unit are all connected to the embedded type core processor. The core processor is used for data processing, analysis, modeling, recognition, fault early warning or early warning decision making.
