Developing a High-Voltage Mechanical Disconnector: Meeting Safety Standards

Sammanfattning: This master thesis is conducted in collaboration with Opticept Technologies, a company operating in the Pulsed Electric Field (PEF) treatment industry. PEF treatment necessitates the use of high-voltage machines, and this thesis focuses on exploring a mechanical disconnector that serves as an essential safety feature for such high-voltage systems. The thesis examines relevant standards and delves into the associated requirements and guiding principles. These requirements and principles are subsequently translated into design criteria that form the fundamental basis for the development process, highlighting their pivotal role in ensuring safety. The master thesis encompasses a comprehensive development process, encompassing concept generation while considering specific design criteria. Through close collaboration with Opticept, the most promising solutions are further refined and ultimately presented as viable solution, accompanied by further development aspects. In addition to addressing specific standards and design considerations, the thesis explores broader aspects of product development. It investigates how the constraints imposed by requirements and existing knowledge impose limitations on design freedom. Moreover, it sheds light on the disparities between concept development for these types of safety systems and the approaches taught in the educational system, particularly in the realms of "product realization" and "product development" specializations. Overall, this master's thesis offers valuable insights into integrating safety standards throughout the development process of mechanical disconnectors utilized in Opticept PEF machines. It underscores the significance of adhering to specific safety requirements and their profound impact on product development.
