內容介紹

        本課程是我校電氣工程及其自動化專業和農業電氣化與自動化專業的專業技術基礎課程,也是電子信息工程等專業的技術限定選修基礎課程。作為專業基礎課程,其總學時數為40學時。

        《高電壓技術》是一門新興的學科。它的發展始于20世紀初,至今已成為電工學科的一個重要分支,它主要研討高電壓(強電場)下的各種電氣物理問題。對于電氣工程類專業的學生來說,學習本課程的主要目的是學會正確處理電力系統中過電壓與絕緣這一對矛盾。事實上,在目前電氣工程類各專業的教學計劃中,《高電壓技術》是唯一研討電力系統過電壓和絕緣問題的一門課程,而且本課程的有些部分(例如電介質的電氣特性、分布參數電路中的行波理論等)還具有物理基礎知識的性質,實屬強電方面各個專業學生知識結構中不可或缺的組成部分。故本課程在我校人才培養中有著非常重要的作用。 

        通過高電壓技術課程的學習,使學生能夠系統、全面地掌握高電壓技術的基本概念、基本理論和分析問題的基本方法;掌握較強的高電壓測試技術;培養學生應用高電壓技術知識,分析、解決實際問題的綜合能力,為后繼課程的學習打下扎實的理論基礎。從而,使學生能夠從宏觀和微觀的角度掌握高電壓的產生與抑制、絕緣的特性與設計等基本理論,培養學生應用高電壓技術知識,分析、解決實際問題的綜合能力,為今后從事專業技術工作和科學研究打下必要的基礎。
