内容简介

本书系统地总结了作者十多年来在SF6与其混合气体中电弧动态特性

的研究成果。书中第1至5章，全面叙述SF6与其混合气体的基本特性和有

关实验研究。第6至9章着重介绍创新建立的电弧二维动态数学模型和所采

用的数值分析方法及其应用。第10至14章，深入分析SF6与其混合气体中

电弧热边界区特性和电弧阻塞现象，并系统地研究其气流特性。最后两章叙

述灭弧室结构参数的综合调整，以改善混合气体灭弧室的开断特性，为在断

路器中应用SF6/N2混合气体取代纯SF6提供了科学依据。

本书不仅对分析SF6和SF6/N2混合气体电弧特性有理论意义，并且对

SF6和SF6/N2混合气体断路器的研制开发具有实用价值。

本书可供高等学校、研究和设计制造单位有关专业的教师、研究生、科学

研究人员和工程技术人员参考应用。

A BRIEF INTRODUCTION TO THE BOOK

The systematical results of the authors' researches on dynamic charac-

teristics of electric arcs in SF6 and its gas mixtures are summed up in this

book. From Ist to 5th chapters, the fundamental properties of SF6 and its

gas mixtures and experimental researches concerned are comprehensively re-

lated. From 6th to 9th chapters, a new two-dimensional mathematical model

of arc and its numerical analyses and applications are presented. From lOth

to 14th chapters, characterictics of thermal bounday region of arc and phe-

nomena of arc clogging in SF6 and its gas mixtures are analyzed. In the last

two chapters the comprehensive adjustments of construction parameters of

the interrupter are introduced in order to improve the breaking characteris-

tics of the interrupter with SF6/N2 gas mixtures.

This book is an academic monograph and applies to teachers, postgrad-

uates, researches and engineers of relevant specialities of universities, re-

search and design institutes.
