Thermal-Electric Analysis of Various Types of Bimetals

Circuit breakers are important components of the current electric power system. It is crucial to make sure that commercial and industrial equipment is adequately secured, and that their circuits have a maximum running time. By preventing electricity from overflowing, inexpensive short-circuit protection and overload protection devices maintain the device's depend-ability. In many electrical applications, an overflow prevention device is a bimetallic component is used. The main goal of this research is to investigate the temperature increase on the bimetal component's tip caused by the electro-thermal load that is created when a current passes through it. The bimetallic composition uses a variety of materials with various linear thermal expansion coefficients. A NSYS was used tom odel a nd analyse t he bimetal structure element on a rated current, and the results were analysed and recommendations for the best current input for the component's maximum temperature rise were made based on the results of the analysis.
