The subject of the thesis is «The methodology development for calculating the arc extinguishing in a combined arrester for voltage classes of 10-35 kV».The given work is devoted to the development of a technique for extinguishing an electric arc in a combined arrester, consisting of RMKE-35 and a 10 kV surge arrester for voltage classes up to 35 kV, capable of successfully suppressing both impulse and fault current. The research set the following goals:Study of the principle of operation of the surge arrester and multi-chamber arrester.Research on papers devoted to the mathematical modeling of these devices.Development of a combined device model.Verification of the model based on experimental data obtained during testing of arresters and surge arresters.Evaluation of the effectiveness of a hybrid device.The work was fulfilled on the premises of Streamer Electric Company Inc which included collection of factual materials, i.e. test oscillograms of the arrester RMKE-35 and surge arrester, characteristics of the surge arrester, schemes of the test facility GIN-300K. To describe the devices under study, mathematical modeling was used, namely, for modeling both the arrester and the surge arrester, âblack boxâ models were used, which are a kind of description of the device functions, where the model parameters were determined based on experimental data. The calculations were carried out in the Matlab/Simulink program.The results of the combined device simulation show that the design consisting of a series-connected multi-chamber arrester and surge arrester is indeed capable of extinguishing the electric arc with no fault current, and the calculation technique is correct, so it can be applied to develop new lightning protection devices in the future. |
