摘要
Abstract
In this paper, the establishment of differential equations of the continuous thermal model, conductor temperature changes with the current process has been fully reflected. The model is adopted to produce the inverse time overcurrent characteristic curves. In order to solve the problem of the inverse-time characteristic curve of exponential calculation into a microprocessor capable, this paper discusses it and puts forward solutions. The simulation shows it can be used in the actual application of microprocessor-based protection devices. It has a higher value of the practical application.关键词
