Motivation and Prospect of Research on Electrical Equipment Reliability
This paper reviews the development process of the reliability research and summarizes the status of the research.General concept and commonly used reliability index of product reliability are described in detail.The new requirements for electrical equipments in China are comprehensively analyzed,and the opportunity and the development space for reliability study of electrical equipments are clarified by considering current development trend of power grid in China,the demand for construction of smart grid,and the change in management mode of grid and electric power administrations.Based on the research of reliability,life cycle cost management for electrical equipments is analyzed,and the significance,necessity and urgency of the reliability research for electrical equipments are clearly described.
Taking Jiaxing University as an examples,this paper discusses how to build a platform for data management of fundamental chemistry experiment and evaluation of experimental teaching.The platform applies average quality control chart and R quality control chart to experimental teaching management and evaluation.By using computer technology,we build the evaluation system that includes input of original data,calculation of quality control factors,drafting a quality control chart and evaluation of the experimental results of students,and have achieved an elementary result.
