The thesis is focused on the calculation of electrodynamic forces that counterwork on moving contacts of compact circuit breaker BL1600 from the company OEZ Letohrad. The thesis is divided into separates chapters that build on themselves. In the introduction the reason why we deal with calculation of dynamic forces and structural arrangement of current carrying path is described. In the following chapter there is a theoretical analysis of electrodynamic forces that conterwork on individual parts of circuit breaker´s element. The third part is devoted to structural arrangement of the circuit breaker BL1600. In this part we can find an example of using the circuit broker Modeion in practice. Two next chaptures deal with adjustment of the model of current carrying path which then serves for the calculation of electrodynamic forces. The rest of the thesis is devoted to my own calculations. These calculations are mainly stationary where we try to find the forces that conterwork on the contacts in a steady current and in a point in time. There are also dynamics calculation when we can watch the forces that counterwork on contacts in a certain time interval. The last chapter is devoted to a stationary calculation of forces that counterwork on the electrical arc which arises while turning the short-circuit current off. The obtained results are evaluated in partial conclusions of this thesis.

Abstract:
This Master thesis is based on problems of force effects of the magnetic field of short-circuit current. Firstly, I analysed the force action of the three phase busbars during the three-pole short circuit. The analysis was performed in the Ansys Maxwell program and I verified the correctness of the analysis by numerical calculation. The second practical part was executed for ABB company. The main task was to analyse the force effects of the short-circuit current in the HV switchgear with focusing on the arms and contact system of the circuit breaker. The simulations of the following configurations were performed in more details: three configurations of the simplified VD4 circuit breaker, two types of VD4 circuit-breaker contact systems and a linear circuit breaker configuration model. The objective was to calculate the forces acting on the current path of the arms and contact system of the VD4 circuit breaker during the three-phase short-circuit and to simulate the effects of forces on these current parts. For modelling of individual assemblies, calculations and simulations I used: SolidWorks 2014, Ansys Maxwell 16.0 and Ansys Workbench 14.5 programs. With SolidWorks 2014 3D CAD software were modelled simplified assemblies of circuit breakers and contact systems. These systems were imported into the Ansys Maxwell software, where the force effects of the magnetic field of the short-circuit current were calculated. In Ansys Workbench programme was simulated the effect of forces on the current circuit breakers. Moreover, the final deformations of the materials (with respect to the mechanical properties of the structure) were plotted. The analysis of force effects of the magnetic field was performed for the specified static short - circuit current value.

Analyzed values are obtained from laboratory measurements, software analysis and 2D finite element method simulation. The theoretical part of this thesis consists of two parts. The analysis of the higher spatial harmonics presents in the induction motor and the analysis of core losses of the motor. Practical part consists of laboratory measurements according to ČSN. Measured values are used to calculate individual losses. The next part consists of creating a model for software analysis (Maxwell RMxprt). The generated model is converted into a 2D simulation environment (Maxwell 2D), where it is adapted to obtain values from the examined parts (rotor and stator teeth and rotor cage). Results of simulations at different loads are compared and analyzed from the point of view of higher harmonics.

Abstract:
The work is focusing on dynamic effects of short-circuit currents, more precisely dynamic effects of short-circuit currents on switchgear cabinet (terminal box). The work was designated to a concrete construction type of two switchgear cabinets located on rotating machines via company Siemens Electric Machines Drásov s.r.o.. The switchgear cabinets are designed for non-explosive environment where the air is used as an insulating medium. The task was to determine how the device will behave during the three-phase short-circuit and three-phase short-circuit with earth/ground connection. The following programs were used for the calculations and simulations: Ansoft Maxwell 16.0, Ansoft Maxwell 2015 and ANSYS Workbench 16.0. By using these programs the effects of forces which acts on current paths in cabinet caused by the passage of short-circuit current were simulated, statically and also dynamically. Further the effects of pressure acting on cabinet frame during the arc short-circuit have been statically and dynamically simulated. All the results are summarized in the conclusion. Conclusion also contains the final evaluation of the functionality of both switchgear cabinets.

Firstly, an electrical machine model and its geometry was built using RMxprt, the design parameters include stator, rotor, slot, and winding. Secondly, the materials of the electrical machine were established. Finally, the parameterization and optimization was illustrated in this paper. Creating a model can be done by mean of two ways, one is from RMxprt transferring to Maxwell 2D, the another is import from some drawing software, the objects of the model need to clearly definition and set up, and then, the model was performed some analysis including static magnetic field, transient, back EMF, loss, cogging, and Electrical Machine Design Toolkit application presenting the machine characteristics and performance. In this study, a permanent magnet synchronous motor with 3-phase, 1 HP, 8-Pole 12-Slot was simulated. Firstly, the parameters were set through RMxprt and a rough sketch of the design was draw. And then, Maxwell 2D static magnetic field, the back EMF, average and RMS torque and D-Q axis transient analysis were carried out. Finally, the simulation results containing torque/speed curve and efficiency maps were demonstrated using Electric Machines Design Toolkit.

The study is on magnetic holding device using NdFeB N35 permanent magnet. The coil winding set up inside the device is energized to generate a magnetic field in order to control magnitude of magnetic flux of the magnetic holding device for the purpose of increasing attachment or otherwise unloading magnetic object. The initial model is analyzed by using ANSYS Maxwell, and the result is compared with the measurement of actual model. The geometric parameters are varied in this analysis when the appearance remains unchanged, in order to investigate the influence on magnetic flux of the device. In the comparison, the maximum error of magnetic flux between the initial model simulation and the actual measurement of energized magnetic holding device is 6%. In the result of different parameters, variation of bottom thickness and internal diameter of the box do not influence magnetic flux significantly. The pole size will change the relative position of coil winding or form a new magnetic circuit. When coil winding is less than 1mm from the surface, it will influence the magnetic flux of surface to a certain extent. Under same power, increasing number of coils will raise the resistance of copper wire, so performance of the device might not be improved. The result also shows dropping voltage will increase current, thus magnetic flux of surface of magnetic holding device can be enhanced directly.
