description: The subject of the graduate qualification work is Â«Investigation of processes in the discharge chamber of the multicamber arrester LLPDE-10Â» The work is devoted to the development of a model of an arc discharge inside a discharge chamber MCA, accounting the deformation of the chamber under the action of the plasma jet flow. Development of the MCA working stand in the MATLAB Simulink product, obtaining the time dependence of the current pulse through the arrester using the circuit for import in to COMSOL Multiphysics model. The research set the following goals: 1. Comparison of lightning protection equipment. 2. Development of a test bench model in MATLAB Simulink and obtaining the time dependence of the current through the arrester. 3. Development of a model of an arc in a discharge chamber, study of thermal, gas-dynamic and electromagnetic processes. 4. Analysis of the results obtained. The main existing methods of lightning protection, their design, working principle, main advantages and disadvantages were studied, the multi-chamber arrester is compared with the most competitive protective device. With the help of Matlab Simulink, the stand was recreated, segmented into 3 parts, each in turn responsible for simulating the line and source, spark gap and lightning pulse. The circuit calculated the time dependence of the current passing through the electric arc block, and the resulting dependence was imported into the model of the discharge chamber. Further, using COMSOL Multiphysics, gas-dynamic, electromagnetic, and thermal processes were calculated, and a picture of the chamber deformation was obtained. Based on the data obtained from the Matlab Simulink and COMSOL Multiphysics mathematical models, conclusions were made.
