Early safety warning model for mining HV cable based on radar chart method
Abstract：To fully access online safety condition of mining high voltage (HV) cable and ensure the safety operation of the mine, a new notion of safety early warning system for mining HV cable was developed. Based on the research about cable aging, a set of index characterizing the insulation parameters was proposed and the weight of each index was de- termined with analytic hierarchy process (AHP). To compare each index from persperitive of time and space, "perfec- tion degree" was introduced to deal with the data in the same measuring scale. Then an improved radar chart method with eigenvalue calculating algorithm was applied to the safety early warning system,in the process of which the refer- ence samples characterizing the impairment of cable and equilibrium factor reflecting the muhisource information fu- sion are adopted, and the result is concise, clear and intuitive. Finally, the system is tested by monitoring the 10 kV mining HV cable, the state of the cable is effectively represented by multi-dimensional data and picture, and with more superiority than other method.
