Abstract


In this paper, ANSYS software as a platform to low Busway system, vacuum circuit breakers and magnetic actuator for the object, the development of the internal electrical equipment field simulation software package main modules - field calculation module. First discusses the development of electrical equipment within the field simulation software package purpose and significance of the internal electrical equipment field simulation analysis of the status and trends, and the main contents of this paper to address the key issues. This paper uses a lot of space studies of low-voltage busbar two series (LD, XL) electromagnetic, structural and thermal performance calculation module development; while in the development of temperature field calculation module, in order to consider the existence of contact resistance, contact resistance carried out measurement; In order to verify the accuracy of the simulation module calculates carried out temperature rise test; additional development of vacuum circuit breakers and magnetic actuator solenoid calculation module; finally, discusses the field simulation analysis module parameterization formation process. Low-voltage busbar insulating properties, analysis and calculation of the single-phase voltage relative pressure and the electrostatic field in both cases, the formation of the electric field of the parameter calculation module. The mechanical properties of low-voltage busbar, the paper used the magneto - structural coupled analysis, extensive use of ANSYS apdl language, the computer program, drawn Busway relatively short in three cases suffered the largest electric power and X- The maximum displacement direction, forming a magnetic - structural coupled analysis module. Air insulated busbar (LD series) thermal performance, using magnetic - Flow - Thermal three coupling method, the magnetic field resulting from the use of indirect coupling Joule heat flow field analysis method as a load, the flow field and temperature field direct coupling, draw temperature distribution; right-intensive (XL series) busbar thermal performance, using magnetic - thermal coupling method, derived from the analysis of the magnetic field as a thermal analysis of the Joule heat load, temperature distribution obtained . The results of the two models are compared with experimental results, the error is small, and because the preparation is parameterized procedures, analysis of changes in its busbar dimensions electromagnetic and thermal properties, forming a busbar temperature field analysis modules. This method other electrical equipment thermal analysis has certain reference value. Meanwhile this paper analyzes the two structures are also calculated vacuum interrupter and vacuum circuit breakers of the electric field phase insulation issues monostable magnetic actuator static magnetic properties, forming a permanent magnetic actuator vacuum circuit breaker with electromagnetic calculation module .
