An alternative methodology for thermoset resin dielectric insulation material insertion and electrical apparatus life cycle predictability

摘要

The successful insertion of an epoxy formulation into an advanced dielectric insulation system may be characterized as an expression of a complex, interactive set of properties and processing parameters; from raw material selection to design configuration. This expression represents the electrical apparatus as a set of structure and component design configurations ordered by assembly methodology to meet a given set of operating life cycle performance specifications. When reduced to their lowest common denomination; the electrical apparatus structure and component design configurations become an expression of interdependent material generic properties; while assembly methodology and operating life cycle performance specifications are reduced to an expression of progressive sets of ambient exposures. This programmatic approach redefines electrical apparatus into a weighted matrix expression of: (1) design configuration constituent material generic properties and their requisite handling parameters; (2) design configuration requisite assembly processing parameters; (3) operating life cycle performance specifications; (4) known constituent material generic property degradation profiles; and (5) electrical apparatus root cause failure history. This matrix expression represents an alternative methodology that will facilitate the timely insertion of new materials into advanced systems and will predict the in-service operating performance of an electrical apparatus while greatly reducing the expense and reliance on full-scale modeling and prototype development.
